My Yahoo Search Traffic is down 50%

[sumitkhare]

I found that my yahoo search traffic is down 50%, I also found that they atlast processed my sitemaps on October 2006, Please help so that I can increase search traffic. I was looking at Yahoo Site Explorer..Also please suggest, if there could exist some problem with my sitemaps , due to which Site's traffic is low? Is there need for some modification in the sitemaps or what are the ideal conditions to be added in the sitemaps...

Don't focus on just one search-engine. Quiet possible that some users moved from Yahoo to Google ( and Bing?). So if the amount of visitors and pageviews did not dropped to hard then I don't see any problem.
