One thing that you should be clear on before we go any further is that improving website conversion rates isn't something that only matters to e-commerce companies.

Websites can also form an important part of your company's customer retention strategy; the 'conversions' that you track can be customers who return to leave feedback, people who sign up for regular newsletters and promotions, or a whole wealth of actions that could prove useful to your business over time. Even if you only build good feeling with your website, the improved brand awareness can still lead to a sale further down the line.

Anyway, moving on swiftly, here are a few key aspects that can help you improve your website conversion rate - whether that means more customer interest or an actual customer sale:

Know your customer: A better understanding of the customer is essential to improving your conversion rates. Dig deep into your web analytics to track click patterns, user behavior, referral sites - anything you can find. It can all prove extremely useful in knowing just why people are on your site in the first place and why they are or are not taking the actions you want them to. Working out why people aren't converting in the first place is a pretty fundamental step.

Don't neglect self-promotion: There's a lot of competition on the web and users are notoriously impulsive in their browsing habits. It doesn't matter if you've got a great reputation if people haven't heard of you. Make sure that if you have good feedback, industry awards or some kind of proof that your business is the best at what it does, then anyone who visits your site will know it by the time they leave.

Be clear about what you do: People rarely throw money at things they don't understand. Well, things they don't think they understand (there is a small but important difference after all). You should clearly explain what you offer and what the customer would be doing when they 'convert' - and you should never, ever be unclear about anything that might affect your customer. People who feel in control are more likely to take action.

Commit to testing: Don't put half-baked strategies into action on your website. Using what you've learnt about your customer, seriously consider what you can do to improve your site before you take any action. Then once you've taken it, commit to it - see how rates are affected over time. You can experiment by all means but make sure that the experiment runs for long enough to be worth doing and make sure that it has a chance to make a change in the first place.

So if you have decided you want to join an SEO reseller program, how do you decide which one to go with? Here are the decision criteria you should use to make sure you end up with a partner that will help you hit your revenue goals. First, don't join any SEO reseller program from a company that does not themselves have good ranking. As obvious as this sounds, it would be like to see a dentist with yellow teeth. If the SEO doesn't use their own approach to rankings with good results, they will not be a good partner. You need to be with a team that believes in what they are doing enough to use it on their own website. If not, you should be worried about the quality of the search engine optimization.

The second criteria when selecting an SEO reseller partner is to try calling them. If you land in a call center where the people on the other end of the phone don't really understand SEO, pass. You want a team at the other end of the phone that is knowledgeable. No, not every member of the entire team will be an SEO super star - but the training in the organization should be strong enough to keep even their entry-level people from saying things you know to be incorrect.

Finally, the economics of the deal have to be good. I listed this one last because it actually isn't the first consideration. You want an SEO reseller program that satisfies criteria 1 and 2 before you even consider the deal. But then the deal has to be reasonable for you. Don't automatically reach for the deal that makes you the most money on paper. Really think about the entire picture. If you are just getting into the SEO reseller space, you probably have not fully realized how competitive it is. You will soon. And the importance of customer retention will hit you in the face shortly too. For this reason, I would join an SEO reseller program that paid me 20% less but kept the customers on-board 40% longer any day. But without a thorough understanding of the search engine optimization space, you would probably first conclude that higher payments are better.

In summary, the SEO space had come a long way in the last 18 months. By every indication, it is a growth industry and has an economic upside to those who want to enter it. Joining an SEO reseller program is a great way to get into the space without investing in the product development and R&D that is really required. And if you use the decision criteria I've laid out here you will find a partner that will help you achieve your revenue targets in this exciting growth industry.

This clearly shows that the candidates can get requisite skills on troubleshooting the network environments. Microsoft is providing quality training by having special class rooms for the students and even practical training is also held that will help the professionals during their work environment. Professionals who are currently working for an organization cannot attend the special classes by Microsoft and hence they can choose their online training classes which are available in the Microsoft website itself. Several career options are available to all successful certified candidates. Network technician, technical support specialists and information system analysts etc are the possible job roles to the successful certified candidates.

1. Picasa Photo Viewer is a quick and Beautiful

Picasa's Photo Viewer provides a nice alternative to the default Windows Photo Viewer. It pops up the image a nice smooth animation and gives you some options that appear in the picture. It'sa very aesthetically pleasing way to view the photos, and doesn't have to use the other part of Picasa! After Picasa is installed, just go to the Start menu, go to Picasa 3, and then click Set Picasa Photo Viewer.

2. It provides a quick and easy Web Backup

I never got a picture on Flickr or other sharing sites, but I think Picasa is a good (and easy) way to keep me back to the company's own image. All you need to do is log in with your Google Account and select Synchronize the Web! Before you do this, you can go to the Picasa, go to Tools and select Settings and then click the File tab to add the file types Picasa, go to the Web Albums tab and change the default size of the Original so doesn't resize your images.

3. Easy image editing

Although it might not be as powerful as Photoshop, Picasa is still an excellent program for editing images. It replaces most of the cases of simple sliders and buttons. I actually prefer this quick edits in Photoshop, simply because of its simplicity and speed. It will also save the original if you ever want to come back. The above image before and after a series of simple slides and press a button.

4. Nice screen saver

Picasa is a really nice screen saver with many different settings. Get it to Picasa, go to Tools, Options. Click Settings to change some stuff. It offers several ways to browse your pictures and you can choose which folders to use it. Or, you can also use the RSS feed!

5. It's Made by Google!

I won't deny it, I'ma fan of Google. I like pretty much everything Google releases. But even if Aren't a fan boy Google, Picasa is Google's yet to gain. It integrates well with Gmail and Picasa Web Albums, and Google loves the Easter eggs! As above. Pressing Ctrl + Shift + Y to see it, and you can continue to press it further. They can also drag around.

For beginners, Chrome OS is Linux. To be precise, it owes much of its genes on Ubuntu. But that's all under the surface. You won't need to know the shell command from GNOME to use it. As in fact, you won't need to know about traditional desktop Linux - KDE and GNOME - either. Chrome OS's interface, Google's browser Chrome. If you use a web browser, you'll be able to use Chrome OS.

That'This is not the case now. Today, you have two options if you want to try Chrome OS. The first of these is to create yourself using Google's instructions. Even though it's pretty trivial for professional users of Linux, it's not for anyone else. A simpler way to try is to visit the Chrome OS blog, fan site Chrome OS frequently that the function is based on the Chrome OS, you can either run from a USB stick, or as a virtual machine using Sun's VirtualBox.

Either way, you should keep in mind that you're working with an outline of the operating system. This is no way, shape, or form the operating system that's ready for prime-time yet. Between it and the recent public comments from Matthew Papakipos, Chrome OS' engineering director, you can see where Google goes netbook with its operating system.

One of the first things I thought about this new operating system is that Chrome is not OS' to replacement Windows. It's a Windows alternative.

You won't be able to run Photoshop, Gimp, or other heavy programs on it. Or rather, it's Linux I'm one that will work out how to do it, but it's not with capital letters, point. Point is not't run standard desktop applications on top of it, point it to run Web-applications.

For example, you can forget about Microsoft Office or OpenOffice to Chrome OS. Google Docs or other Web-based office software such as Zoho, will be what you use for desktop software.

In short, if you can run from the web, you should be able to use Chrome on the PC OS. If it's a traditional desktop applications, even though it's Linux-based, you won't be able to run it. You also won't be able to run Android-specific applications on it (the Google Android's smartphone operating system.) Chrome OS doesn't even support Dalvik runtime program that allows developers to run Android on other operating systems. Sometime in the future, which may change, but so far it's Chrome for netbooks, smartphones, and Android for two don't meet.

Although this is subject to change, there are currently two ways to get into the application. The first is to show web applications in different tabs, while others show more Chrome browser window and allow the movement of applications between Chrome browser windows. To some extent this reflects the different types of applications: programs that you expect to run in a web browser window and those you expect to run as a separate program. Google is working to erase the differences between them so that the web browser interface is becoming a universal interface for all applications and websites.

That doesn't mean that you won't be able to Run for serious business applications in Chrome OS. You will. They'll be only be SaaS (Software as a Service Programs), as SAP's Business by Design, SugarCRM or Salesforce.

Thou't, however, must be tied to the Internet through the use of Chrome OS or Web-based applications. Chrome OS uses Google Gears to frequently used applications and data on your netbook. Gears works to keep the cache a copy of your programs and data on local disk. If the user so everything is visible. For example, if you need to edit the document, and you're offline, but it's found in Gear's cache data, you'll have to do the same as if you were online. No problems, no muss.

You also won't have to be online to view or play multimedia files. Already we know that Chrome OS will be able to read Adobe PDF files, Adobe Flash and video playback. Now we know that Google is a media player to integrate Chrome OS, which will at least play music in MP3 format. This will certainly play a different media file types, as well, but exactly what you, we don't I do not know. We know that you won't have to be online to play with. So for example if you have a movie in MP4, USB stick, you'll be able to watch it, even if you are not online. Again, the intention is not't click on the movie file and have the media player pop-up her play. Instead, the movie will start playing in the browser window. Chrome OS is all about everything integrated into a Web browser experience.

Flurry Analytics on Friday released its latest edition of the "Smartphone Industry Pulse" for January 2010. The mobile analysis firm, which has tracking data in over 20,000 mobile applications, said developers integrating Flurry analytics into iPhone OS applications in January increased nearly three times over December's total.

More than 1,600 new applications for Flurry started in January, when less than 600 at the beginning of December 2010 represents the largest increase in history, the analysis starts the company's follow-up.

"Thus, we hypothesize that the excitement generated by Apple's iPad event in January to guide the growth,"the company said."For developers who are customizing their applications to skip the iPad, may have the opportunity to stand out early on, and make more money on downloads."

Apple revealed the iPad the event that there is over 140.000 applications available on the mobile App Store. That the software is compatible with the iPad when it first appeared in the end of March.

But developers can also create a new iPad specific applications that take advantage of multi-touch device and its 9.7-inch display

While the App Store as a huge growth of new Android applications increased by about 25 percent in January, continues a steady ramp in Google's mobile platform. However, Apple's App Store spike helped to push it further before Android.

"Although the Android's new application for a steady growth in the second half of 2009 closed the gap against the iPhone, and it was even one of the three new application for Flurry starts in December, the last Spike Apple iPad support has swung the pendulum back to Apple's benefit level was observed Flurry six months,", the report states."In an unprecedented rise in support iPad is a positive indicator of the beginning of its commercial potential.

Link building

Note: This was tested on Ubuntu 9.10. Previous versions of Ubuntu require different procedures because of changes to the way Ubuntu boots.

Open /etc/init/tty1.conf as root:

sudo nano /etc/init/tty1.conf

Change the last line of this file to (where USERNAME is the username of the user you want to log in):

exec /bin/login -f USERNAME < /dev/tty1 > /dev/tty1 2>#038;1

Reboot, and the user you chose should be logged in automatically after boot. If something goes wrong, you can switch to a different TTY with CTRL+ALT+F2 and log in normally.

If you want this user to be logged into a graphical environment instead of just a shell, there#8217;s more work to be done. Open your user#8217;s .bashrc file:

nano ~/.bashrc

Add the following to the end of the file:

if [ $(tty) == "/dev/tty1" ]; then
 startx
 fi

This code will start X (the graphical environment) whenever the user logs in on TTY1. You can add more code after startx that will be executed if the user logs out of X.

II used my usual technique to install the new version of Ubuntu. I'm using a separate home and root partition. To use a custom installer Ubuntu partition and converted small partition using the new ext4 file system and use the old boot partition as the new boot partition. Setup has finished in less than nine minutes. Before leaving the live CD, opened a file browser (Alt-F2 and "gksu nautilus") to remove the old configuration files (files and folders from the period in your home directory). With the exception of a few applications I don't want to have to reconfigure, I moved the old config files in the backup location. This allows me to start new applications and application configuration, without having to backup and restore my data.

Ubuntu 9.10 is out for a while now, so surely everyone knows what's new. I'll just mention a few things I've found setting up the new system.

The default theme (and especially the icons) are much improved in Ubuntu 9.10. But I'm not a fan of orange so I installed the elementary theme (just the GTK and icon themes). I'm getting a warning that I don't have the right theme engine installed, but I like how it looks so I just ignored it.

The first thing I noticed after installing the Nvidia drivers and getting Compiz running was how moving windows around looked jerky. I reapplied my settings from Make Compiz Run Smoothly and Without Tearing to fix Compiz's refresh frequency and now it's back to being smooth.

I'm using Chrome for web browsing now. Before the upgrade I was using the daily builds of Chromium. I used Google's bookmark sync to save my bookmarks, but couldn't restore them because the official release of Chrome lacks the sync feature. I couldn't find a way to get at the bookmarks online (why isn't this integrated with Google Bookmarks?)(update: A commenter points out that bookmarks are available in Google Docs), so I copied .config/chromium/Default/Bookmarks from my backed up configuration folder to the new Chrome configuration at ~/.config/google-chrome/Default/Bookmarks.

I installed Ubuntu Restricted Extras as usual to install Flash, Java, web fonts, and media codecs. For some reason this didn't install the Java plugin. I installed 'sun-java6-plugin' separately to fix this.

After installing the latest version of GNOME Do I was pleased to find that it can now open my home folder. This bug (I think it was actually in Nautilus) has been annoying me for ages.

I added the new Wine PPA to get the latest versions of Wine. Trying to install the 'wine' package failed with a "unresolvable dependencies" error. Installing wine1.2 instead worked (all 'wine' should do is install wine1.2 anyways). There's a forum thread about this issue.

Ubuntu 9.10 has a little mail icon near the notification area called Indicator Applet. I'm using web-based mail and instant messaging, so the Evolution and Empathy integration aren't useful for me. I am using a utility called Gmail Notifier which integrates with Indicator Applet and Ubuntu's notification system. When I get a new email it pops up one of Ubuntu's fancy notifications and lights up the mail icon.

But spammers are always there to exploit any opportunity they could find. Then also use this technology and use the old domain is nothing more than a link farm. Spammers tend to make use of link farms in order, although age domains are lots of good links more weight to get a higher ranking. Apparently, search engines hate these tactics and have tried and still trying to find ways to combat these link farms, both old and new.

Microsoft has tried to combat this problem by looking not only at the age of the domain, and the number of sites linking to it, but also an age of the domain of those sites. This means that although the link farms can get lots of incoming links those links would not't keep as much weight as links from older, more reputable sites, since most of the sites, joining link farms are new. MSN Live Search factors in not just the domain age of your own side, but the domain age of the pages linking to you also. This means that even assemble a large quantity of links is no longer enough, if the search engines find these compounds are of low quality links. Two things that have been treated in an age of a domain are: age of the site and how long a domain has been registered.

On the other hand it means for ordinary websites, what is that it will make it a bit harder to do link building because we need to get more links from older sites. Add to the relevance of the site, and all these factors, what it simply means that organic link building makes more sense since search engines can find better ways to determine which sites are really offering something of value and not.

The new service allows users to bypass your own Internet service provider's DNS to use Google's performance-optimized servers, name lookup. Internet users continued access to the DNS in the background every time you enter a URL in your browser, click the hyperlink, email, or perform any other task to resolve IP address of host names.

User's currently assigned DNS server may be overloaded, slow, or even maliciously poisoned provide bad information. This means that Google's new services so the potential to improve the efficiency and safety.

Users can search by entering a new Google's difficult to remember DNS IP addresses (8.8.8.8 and 8.8.4.4) to replace their existing DNS settings, either individually on each computer used by, or central to your AirPort base station or other router, which will then have access to Google's DNS to perform all network query host name.

No redirection, blocking or filtering

Other free DNS services are already available, but most cover their costs by shifting is not a query (for mistyped or incorrect URLs) for ad-supported sites that propose alternatives. Until now, Google in March't perform any conversion of such business. Instead, the company providing the service for free as a way to collect information on how Internet users in anonymous and aggregate level.

In its Google Public DNS information page, the company stated,"Sometimes, in the case of queries for mistyped or non-existent domain name, right [DNS] response means that there is no reply or an error message stating the domain name could not be resolved. Public Google DNS never blocks, filters or conversion of users, unlike some open resolvers and ISPs."

Google also provides detailed instructions on how to use their new service, including free telephone support. It also explains performance advantages in security benefits their new services.

Google's network of savvy and ability to handle huge amounts of public requirements would be uniquely placed to offer this service free of charge to the public. The company itself describes the services offered to quickly caught, as every typical user loads a Web page in the browser include several or even many DNS queries, each of which can stall the progress of loading pages, if it can not be resolved quickly.

So, external links, which are listed on the site should add value to existing content. If a web site but don't provide services, then makes perfect sense to recommend some quality visiting Web sites or resources. Similarly, a company can link to a website or websites that provide search engine web page designs or sites which contain useful web design tips and tricks. So it is that we should be concerned. Another risk is the very fact that promiscuously exchange links with different types of websites can damage the reputation of your website, and can not be a punishment for links to websites which have a bad reputation. So uncritically put the website link does not work for you more.

When you have a lot of quality incoming links, to communicate to search engines that your website contains very valuable information and therefore should be ranked higher on a related topic. Even when links to other websites and if these external websites containing information, then too much trust your website deserves a higher rank. So when it comes to exchange links, then always remember to share your connection with some other link quality but not the mass and quantity of links that can damage your purpose, instead of doing good for your site high.

Search engines consider the number of quality incoming links, they are telling the popularity of a specific site for that keyword. Now your are happy that you get more incoming links, but the fact is your links now and should be interrelated and voluntary. So when you exchange links then do not forget to share with some other link quality but not the mass and quantity of links that can damage your purpose, instead of doing good for your site high. It is all about building quality links in search engine optimization.

First is that you need to look for the right keywords or phrases. Before you create a good website, make sure you know what type of business you are in and choose an appropriate keywords that would fit perfectly in your products or services. It is very important for you to search for the right keywords, as this will serve as your tool to locate your business. And do not forget to use the keywords, at least 5 times in your pages, then there will be chances that your website will be opened and the perception that users of the website. I'll give an example, if your business caters more about dresses, and so after a perfect or near word for dresses.

It can be a garment or it depends on what kind of dresses you have to. Just be specific and precise by selecting a keyword or keywords. Internet savvy people will easily see your site, because these keywords commonly used by most website users. And they can easily find your website with just one click. Another is to do your part is minimal content. It is the most important rule of Search Engine Optimization. Website users prefer to visiting sites that have a minimal content of the page than long, wide pages. It will certainly cause them to be bored to read all your pages. It would also be very time consuming to read all the pages. So create pages with minimal content yet very informative and easy to understand. But you must not make it so complicated, but make it as simple as you can. The content of the pages should be over 300 words because some search engines will penalize page in search engine rankings. In fact, sometimes if it is really necessary is it still ok to have a long scripted page that would be inserted on your website. The Web users will just scroll down until they get what they want.

If you have a site of your own and wish to keep a close watch on it all the time, this service will come in more than handy. Presented by MazeCore, it will enable you to keep track not only of aspects like positioning and ranking, but it will also let you monitor the number of backlinks and social bookmarks in question. The system also makes for getting instant alerts whenever certain events take place. For example, you can be informed when your site is down so that you can remedy that without wasting a single second. The alerts can be put your way both by e-mail and/or text message, and you are free to specify how often your site will be checked.

A sister service that goes by the name of “Analyze” is likewise available, and it complements this one quite well. That particular service can be found at Analyse.mazecore.com, and if you found this one compelling it is fair to say you are going to appreciate it, too.

Services like this one do never come amiss. It monitors every single aspect a webmaster looking for better traffic figures would look for. Not only that, it takes cares of notifying duties, and that is equally important

Manually downloading and installing Firefox from Mozilla every time there is a security update is not a great option either. Instead, let’s use Ubuntuzilla, a script that can install and update Mozilla applications outside of Ubuntu’s repository system.

Ubuntuzilla can integrate the new version of Firefox into your system as well as undo its changes if you want to go back. All your extensions, bookmarks, plugins, and settings should transfer over to the new version. The only thing that didn’t transfer was my open tabs from my previous session.

1. Visit the Ubuntuzilla download page to find the latest deb package appropriate for your system (32 or 64-bit). Download and install the package.
2. At this point you should completely close Firefox.
3. You’ll need to use a terminal to let Ubuntuzilla guide you through the installation. Run this command to start:
   

   ubuntuzilla.py -a install -p firefox

Ubuntuzilla will ask a few questions: confirming that it has found the correct version to install, choosing a localization (14 for en-US), confirming the localization, a sudo prompt, and a prompt for enabling automatic updating.

4. Near the end of the process you should see The new Firefox version 3.5 has been installed successfully.

You can now use your normal Firefox item in the menu to start Firefox 3.5, or by running the command firefox. Check out Ubuntuzilla’s website for the simple removal instructions as well as what do do when you are notified there is a Firefox update available.

[update] Mozilla has released Firefox 3.5.1. I followed the instructions on Ubuntuzilla’s page to update to this new version.

I’ve come across two bugs so far in Firefox 3.5: clicking the middle mouse button anywhere on a page tries to load a URL from the clipboard (fixed using workaround), and fullscreen Flash video crashes Firefox (waiting for a fix or better workaround).

Here’s how you can easily install Google Earth on Ubuntu.

./googleearth-bin: relocation error: /usr/lib/i686/cmov/libssl.so.0.9.8: symbol BIO_test_flags, version OPENSSL_0.9.8 not defined in file libcrypto.so.0.9.8 with link time reference

• Boot performance has been improved, even without Ext4 you should notice a speedup.
• The slick new notification system is enabled.
• The latest version of the GNOME desktop environment is included.
• OpenOffice has been updated to version 3.0.
• Ext4 filesystems are now supported (but Ext3 is still the default for now).

If you’ve installed from an alpha, beta, or release candidate CD all you need to do is install any available updates to get the final release version. If you need a CD, be sure to use the Bit Torrent downloads.

Hedgewars is open source, and packages of the latest version are available for Ubuntu at GetDeb.

From Hedgewars’ setup interface, you can jump right to quick game against an AI team, start a multiplayer custom game, connect to a network game, or host your own Hedgewars server.

One feature I really like is the teams setup. You can create your own teams, name their members, choose from a selection of hats for the hedgehogs to wear, and even choose what voice your team will have.

Here are the in-game controls you’ll need to get started: move the current hedgehog (right and left arrows), aim weapon (up and down arrows), control power and fire (hold left mouse button and release), open weapons menu (right mouse button), jump (return key). See the Hedgewars FAQ page for more controls.

For Lighttpd there is mod_expire module. Enable it in server.modules section:

server.modules = (
...
"mod_expire",
...
)
Then add following directives for directories with static files:
$HTTP["url"] =~ "^/images/" {
expire.url = ( "" => "access 30 days" )
}

Max-age for Nginx server can be enabled using ngx_http_headers_module:

expires max;

Now web server sends the caching header for static files:

Cache-Control: max-age=2592000

In case of design change we should prevent using outdated content that browsers have in their caches. This can be done by adding file versions to filenames:

script.js -> script1.js -> script2.js -> ... etc

header('Cache-Control: max-age=28800');

For Apache2:
compression done by mod_deflate

AddOutputFilterByType DEFLATE text/html text/plain text/css text/javascript application/x-javascript text/xml

For Lighttpd:
enable mod_compress in lighttpd.conf and add configuration directives:

compress.cache-dir = "/tmp/"
compress.filetype = ("text/plain", "text/html", "application/x-javascript", "text/css", "text/javascript", "text/xml")

Nginx configuration directives:

gzip on;
gzip_min_length 1000;
gzip_types text/html text/plain text/css text/javascript application/x-javascript text/xml;

Besides compression there is minification (removing comments and unnecessary whitespaces) that can further reduce size of Javascript.
Minified Prototype.js becomes 92KB size uncompressed and 23KB compressed, this is 20% less than compressed non-minified script.
There are number of tools for minification exists, I’m using JSMin (http://crockford.com/javascript/jsmin).
