AJAX, Web 2.0 and SEO

AJAX offers some incredible new functionality for web sites, but it is not SEO-friendly by default. However, you can still successfully optimize a site that uses AJAX and Web 2.0 technologies. This article discusses some of the problems and solutions for AJAX SEO.

Get Google and AJAX to Play Nice

The best ways to incorporate the benefits of AJAX without making your site blind to search engines.

«If you build it, they will come.» It seemed to work for Kevin Costner in Field of Dreams, but when it comes to your AJAX website, a great design just isn't enough to bring in an audience.

AJAX gives developers the ability to build dynamic web applications without the need for constant server side script parsing, enabling you to provide users with simulated «load on demand» sites. That means shorter page loading times, a sharp decrease in bandwidth consumption and more accessible information in general.

In plain english, that means that in Google's eyes, many of your AJAX site's pages are invisible when it comes to search engine ranking.
