Welcome to the Q&A Forum

Hi All, It looks like Google has setup a nice dev site and FAQ page to go over the options here especially when using AJAX and hash tags to link to that content.https://developers.google.com/webmasters/ajax-crawling/docs/faq#whereinresults. It looks as if Google will be able to index the content of the entire page (hidden and initially shown) and not create a separate URL if you use a ! before the #. I'd read up on that FAQ page, and play with site commands on the Google dev site.

Hi Joel, Actually, the keyword difficulty tool is exactly what I needed. Thanks for your help! Ana
