Can Google index content from within Facebook apps? (photos, events, custom app, etc.)

[millennium-marketing]

Hi guys,

I've Googled the heck out of this query and I seem to run into very top level answers (and I do apologize if my ignorance is to blame), but is Google able to index content from within Facebook applications such as Photos, Events, and possibly a custom app?

If Google is able to better index both Javascript and AJAX, I would assume that the simple answer would be "yes", but since many of these applications don't provide outbound links, tracking traffic and conducting follow up experiments appears to be quite difficult.

Since many of us use Facebook as a destination, if we take the time to optimize deeper content by adding detailed captions in pictures or unique descriptions for events, how can we determine that 1. the content is being crawled by search engines and 2. how is that content crawled and disseminated for user consumption on search engines?

I appreciate your time and thank you for your insights.
