IS there anyway i can see G SERPS pages with the last update of the sites?

If i am going to:
http://www.google.com/search?num=10...r:y9&q=allinurl:ageseo.com&aq=f&aqi=&aql=&oq=
i can see the first date of when pages were indexed

is there any trick i can do so i can see the last date of the pages. (when the page has been updates/or last crawled by google) ?

 

Yes, with Google Webmaster Tools.

Another way would be: There would a "cached" link for every result when you search "site:yourdomainname.com" in Google. You would find the most current information there.

Have a nice day,

 

You can also use the "specific dates" function listed under options when you do a search.
