Existing indexed pages that are changed

[nadsab]

Hi,

I have several sites that have been on google for several years now. Each site has anywhere from 20 to 150 pages indexed in google. For some stupid reason most of the pages have the exact same titles, they all have the company names that's it. I never bothered with the titles. Now I'm changing all the titles to reflect the page content, they will all be different.

I was wondering when I do this, does google automatically, if a web page is in the index, revisit every page in the index? And will all of these pages be updated in the new index to reflect the title changes I made, or is it a random process and some may get changed and some may not?

Thanx

I've just done this for three of my main sites and google picked up the changes when the freshbot visited.
