I am thinking to convert one of my site to ajax to save bandwidth but not sure how to do seo since data is not seen by search engines. If you have experience with it, I really appreciate your comments.
Just use AJAX for stuff that wouldn't be sniffed by search engines in the first place. Forms, search, list sorting etc. And if you insist on info slide-ins or whatever, just make sure there is a static version which fits on with your site's workflow.
I beleive AJAX is getting more popular isnt it? so i would imagine there shouldnt be any sort of problem with regards to search engines unless you have errors in the code.
On the client side, which is what the bots see, AJAX is simply javascript. The bots don't grok javascript. Best practice calls for a POSH[1] site, enhanced with AJAX. If the AJAX javascript is in a separate behavior layer[2] on top of POSH, SEO will not be compromised. People without javascript will not be barred from full usage of your site, while those with javascript will enjoy the enhanced experience. cheers, gary [1] POSH is Plain Old Semantic HTML [2] Javascript should not be mixed into the html, nor be integral to the document.
