What I need to do?

Hello,

I have a website, I have 100+ of urls that are now showing 404 and are index in google. I have new urls but new ones are not index, instead old ones are indexed. What I need to do to remove the old one and make the new one index.

Thanks

Use search tool on left hand side..plenty of threaded about this alreadyk

GO to webmaster and submit sitemap. Also do this for the other Search Engines
