Cache Problem

[PierreL]

I have picked up a problem on the indexing of our site. It was previous
developed by someone else on a .net framework. The site was submitted to
Google index. Since then we have scrapped the old site and redeveloped
it. I still find old link on the search index pointing to pages on the
old site. I even find under the image search. Is it possible to clear
all FlyTalk.co.za related pages from the search index and re submit the
site for index. I have gone through great lengths to optimize the title,
description, keywords and also body text and still getting a poor
ranking on the most common word used which has a very high density on
the site namely, fly fishing. I have looked at other sites raking well
under this keyword and my site has been far better optimized than their
site. Sites not even fly fishing related ranks higher than me and they have absolutly no keywords etc.Really puzzling I hope someone can advise.

You should make a custom 404 error page so that Google doesn't find pages which aren't there anymore.
With time, Google should index the new pages.
