I have a website which title I changed about a month ago. The website is a classifieds website which is dynamic, using php.

The title changed from "Free classifieds" to "buy and sell free classifieds".

The strange part is that after about two weeks the title showed in google search results changed to the new title, BUT when I searched for "buy and sell free classifieds" my website didn't show up at all. I mean I have gone through over 30 pages of search results and my site isn't listed.

However, searching for "free classifieds" still display my website at the same position it was before the title change.

Any reason for this? How patient should I be?

FYI the website has a sitemap submitted and updated, good meta tags and is W3 valid etc etc, so that is not the problem here.

Thanks
