AJAX allows a developer to query a local or remote data source and render that content right to the browser without refreshing or reloading the page. This gives the user a much more responsive experience, if you have ever used Google Maps or the new web apps like Google’s Docs & Spreadsheets beta, you will no doubt understand the power of this wonderful technology. Now with all the new AJAX toolkits out there it is easier then ever to dive in and use this technology in your web projects. Expect to see it in use very often in the coming years.
Recently I tried to find any information I could regarding SEO and AJAX. I have had much fun playing with it in the past and wanted get back into it, but this time I am questioning it from a SEO perspective. I have yet to find a good reliable solution to get AJAX content indexed.
