We know that JavaScript or JS is being used more and more by web designers and developers to improve the usability of the websites. It seems that Google has also given a stamp of approval to use of Java by Indexing of AJAX & JavaScript.

Here is confirmation from Matt Cutts in tweet at his twitter account

“Googlebot keeps getting smarter. Now has the ability to execute AJAX/JS to index some dynamic comments.”

On Webmaster Central Blog, Google has explained it in more detail as well which can be read here


Now Facebook comments are being indexed by Google which means many third party commenting software platforms which are based on Java or Ajax like Disqus will be properly indexed by Google, We know that Disqus is widely used by webmasters on Word Press Blogs and Popular blog commenting software.

So now its important that you block Java files in robots.txt correctly which you do not want to get indexed by Google.

Execution of AJAX/JS to index dynamic comments by Google’s spider or GoogleBot also shows that Google has improved its crawling to index content in JavaScript or AJAX as compared to other search engines like Yahoo or Bing.

For SEO’s and Marketers, this is good things as lot of links which were not indexed before this change, will now be indexed and they will get more link juice. It will also change behavior and thinking of SEO’s towards importance of dynamic contents in terms of SEO.

We here at Submitshop tested and found that some of the Facebook comments are being indexed very fast.
