Google Can Now Execute AJAX & JavaScript For Indexing

This morning we reported that the comments on Facebook are being indexed by Google. Google’s Matt Cutts just confirmed on Twitter that Google is now able to “execute AJAX/JS to index some dynamic comments.”

This gives Google’s spider, GoogleBot, the ability to read comments in AJAX or JavaScript, such as Facebook comments or Disqus comments and others that are dynamically loaded via AJAX or JavaScript. In addition, this means, Google is better at seeing the content behind more of your JavaScript or AJAX.

Well, this is a really good and big step. I just wondering that whether Google has not started all Ajax and JavaScript files or its just facebook comments?
