I have noticed that one of the sites I manage has disappeared. No real reason. There was similar content with other sites (maybe a paragraph or two) but that is the only thing I can think of. Is Yahoo punishing large corporations who have huge databases? Do yahoo updates have names similar to Google (eg. Florida)
One of the sites I have shot to the top of some Yahoo results two days ago... maybe the same "update"?
Could be, how many pages are you talking? This site was template driven and was probably 5000 pages deep. It is a terrible thing to have this happen. Obviously Alta, ATW and others are toast as well. PS: Anyone know if AOL has their own algo?
Two data: 1. My Yahoo standing for the site I check there has been essentially unchanged from many weeks (or, by now, probably months) ago to a minute ago--swings are on the order of +/- 1 position. 2. Yahoo is still listing the site under a URL for that has been issuing a 301 redirect for those same week or months now. Either they ignore redirects, which seems unlikely, or they don't update very often. I also note that a couple of comically obvious search-engine spams (try this one: fantasy|science|fiction|hughcook|com, replacing the | with a . ) still place high, as does a site apparently two years dead.
AOL results are based on Google. I'm not actually tracking anything in Yahoo... I just noticed it because of the referrers.
WOW, I cannot believe that search return. Makes me question Yahoo's validity. I have to feel that this is some long, drawn out process of updating. Google, returning 188 links to the homepage while Yahoo is showing 6. Something is not computing. If I do a 'site' search in Google I get 38,700 returns, Yahoo is showing 22.
Ive noticed yahoo spidering more- they don't seem to go as deep into the site. They seem to find the basic catagory pages and then base their results on the on page content.
yahoo's SERPs are so unpredictable. we've done a ton of optimization, onsite and off, waited months, and there's been barely any improvement (while there was HUGE improvement in google's rankings).
Around the time this post was first generated, I noticed a huge difference in Yahoo results. It seems to me that they have changed their keyword density requirements. For a while one could have a very saturated page and stay high. But now they seem, stricter; one must clean their code up to get back up high.
