wen you search for my site on google, instead of displaying the keywords it just diplays the text on the site, why does it do that?. Also the title is wot my old title used to be; i told the robots to revisit after a week (by placing this speical meta thingy) would the title change to the new one?

First off, major search engines don't even look at meta keywords anymore. At ALL. Secondly, the only meta tags you should use are description and character encoding. Google robots your site oftenly if your site is high ranked, if it is not then they won't robot it as much.

Google displays the text from within your site to give users more relevant search results...

So it displays a short sentance or two highlighting the keywords they searched
