Traffic from search engines suddenly stopped!

[Victoriatus]

Hello,
I have a site for 1,5 year and especially during the last 4-5 months the search engine ranking was good. For some popular keywords my site was in the firs
0-20 results. Suddently before 3 days my site stats went dramaticaly down. I am still trying to find what happened. One thing i noticed is the traffic from search engines like google or yahoo was decreased over 500%! Is this normal for search engines?

Hi Victoriatus and welcome to Webmasterworld!

Check out the Google forum and the thread 'Major Google changes' - you could be one of those sufferring through the limited Google update. There's also been a Yahoo update in the past few days so it could be that you've suffered in both.
