Those are the DMOZ results. Look, the description matches with the Google directory one (which is DMOZ) and not with the site´s meta title: hxxp://www.google.com/Top/Computers/Programming/Languages/PHP/Scripts/Forums/phpBB/?il=1
You must submit your pages in DMOZ to be listed like that. Then if your site is in top 1, you would see the results.
I don't think its because of DMOZ.........I'm not sure the criteria for it but it always seems to be strong, reputable, authority sites..
DMOZ is Open Directory. An open source directory, that you can use to use its results in your website. Google Directory uses DMOZ results.
DMOZ has noting to do with results like that. They're called sitelinks and appear when your site is recgnised as being an authority on a particular search term. http://googlewebmastercentral.blogspot.com/2006/09/information-about-sitelinks.html
you can do nothink for that . read http://www.google.com/support/webmasters/bin/answer.py?answer=47334
Well, my guess is based on examples. As you see the one that I put above, you see that the Title and Description that Google is showing is not the meta tags of the site, but the title and description of DMOZ. And yes, I agree, it does it when a site is trustworthy and has high authority.
READ THE LINK - http://googlewebmastercentral.blogspot.com/2006/09/information-about-sitelinks.html It's NOTHING to do with DMOZ. People complain that they don't know how Google works, but even when they tell you themselves people still don't know.
