Sometime on June 13th my main site was hit with a 95+% drop in visits from Yahoo.com. Since I get most of my traffic from Yahoo, I took notice to say the least.

Yahoo's Slurp spider is still indexing my site constantly, so much so that I put the crawl delay in robots.txt to slow it down (after the drop in visits, thinking it was bogging down my server).

The domain in question currently has 400,000+ pages indexed in Yahoo, so it's not a banning issue as far as I can tell. Once thing I did notice that when using Yahoo's site explorer when you click on the "Cached" link under each listing, the cached page is displayed. BUT when you click the "Current Page" link at the top of the cached listing in goes to my home page instead of the current version of the cached page. Could this be part of the problem, some kind of weird redirect issue? I could not duplicate the problem with other sites in Yahoo.

This traffic drop occurred sometime around 5pm Eastern Time on June 13th (Wednesday). It was almost like a switch was pressed. The sit gets several thousand visits per day, and now it's a couple hundred or so.

I even switched over to me backup server on a completely separate web host (thinking server issue), and traffic has not increased. This pretty much isolates the problem to Yahoo's end.

I'm at wit's end.... any ideas, anyone?

Hi there was a Yahoo update last week, maybe your rankings were hit by that. Couldn't say any more without the url really, but Yahoo seem to be a bit more picky about backlinks. Most of my sites did well but I have a shopping site with very little on-page text and it got hammered in Yahoo.

Cheers,
Paz.
