Google Cache Date

[PMC-312087]

The Google Cache date for my website:

This is Google's cache of http://www.petmedicalcenter.com/. It is a snapshot of the page as it appeared on Aug 28, 2011 03:19:05 GMT.

Does this date coorelate to the last time Google reevaluated their rankings for my site? So if I had done 15 or so backlinks after the August 28 date, will those start to affect rankings (once they are discovered) after the next time the site is updated?

Google has a public cache (i.e. what you see in the search results) and it's own private cache which is used to evaluate site rankings.

Although when the public cache is refreshed it more than likely updates several ranking factors, there's also crawling done behind the scenes. Backlinks can and most likely will be picked up before the public cache is refreshed.

I've noticed google is getting quite fast on updating rankings and new back links can have an impact sometimes within a day or so now.
