Spam Attack on Yahoo, or Updating Algo?

[sanjalee]

Im seeing very strange results on yahoo. We were 1st for our major terms and now we are 90th with everyone that was top 10 in worse posistions then us. Above us are just spam results.

I am wondering if this is just some kind of huge spam attack on the yahoo search, or if its yahoo updating its algo, and in the middle these results would come through then go to their new results?

Any ideas?

It could be either spam attack or algorithm update. What are some of the keywords? Yahoo did just do an algorithm update around March 27th. I wouldn't be surprised if they followed it up with another one recently. Some spammer could've also figured out something offpage that Yahoo penalizes for.

I have had the same problems with yahoo, though when I was looking through my stats on G A and stat counter I noticed some very strange searches that were repeated within a certain amount of time. Have you considered you have been hit with black hat seo tactics? I would do a double check of your backlinks to make sure they are not being placed on link farms.

It was due to Algo Change, Yahoo is trying to get its lost visitor back.

May be you'll get your ranking back after a few weeks. May be this is temporaly.
