Yahoo Results Bouncing Back and Forth

[RobinK]

I went to check some keywords and ranking in yahoo and I am seeing yahoo bounce back and forth between two sets of results. Anyone else seeing this?

The pure SERPS are on Alltheweb and Altavista. Y! then takes these and blends a subdomain penalty and promotes YSM! search partner sites to produce the Y! SERPS.

Yahoo (Google, and many other sites) use subdomains (for instance, to seperate services, like adsense.google.com), so I dont understand having a subdomain penalty.

kwasher,

That comment was prior to this update. Y! appears to be getting its act together!

There's a big difference between adsense.google.com and how-to-make-money-with-adsense.im-the-big-winner.com

Looks like Y! has now better addressed subdomains with this update.

Does anyone know how to get Yahoo to actually obey a robots.txt file? We run a .ca and .com and have a complete ban on all engines for the .ca, but Yahoo is the only engine that doesn't seem to want to listen to it.

Any suggestions?

IP Range Based detection might solve your issue

IP range detection as in banning Slurp based on it's IP addresses? That's a bit scary considering our .com site resides on the same box.
