Google & async="true"

Hello,

Any idea if Google (or Bing) parses/indexes content from scripts that are loaded using the async="true" attribute?

In other words, is asynchronously loaded content indexable?

Thank you.

They're indexing AJAX comments for sure (e.g. Facebook comments - see http://www.searchenginejournal.com/google-indexing-facebook-comments/35594/), and on one of my sites where the main page content is loaded via AJAX, Google is indexing the text, because when I search for that exact text, it's returning that page. This was nice, because my developers weren't looking forward to having to implement the HTML snapshots as Google suggests in http://code.google.com/web/ajaxcrawling/.

So, Google is already doing it, and presumably they'll only be getting better at it.  That same search that works in Google doesn't work in Bing, so I think Bing is behind with crawling AJAX content.

Thanks for your reply John.

Yes, you are right about XHR related content.

What I was asking was about content being injected into the DOM (Document Object Model) using scripts which are loaded asynchronously using the async attribute.

I believe this is a different case.
