I posted in this thread http://forums.digitalpoint.com/showthread.php?t=17924 about the changes in my Yahoo rankings for my coop sites from yesterday to this morning. Is anyone else seeing a drop in Y for coop sites? The only words I still rank for are those tied to my paid Yahoo directory listings.
I have seen a penalty for sure. Be cautious of how much weight you push to a site. I am waiting though as Yahoo seems to be sorting through some new algos the past few months.
The sites have been in the coop for over 6 months with pretty consistent weight. One of the sites only had 2% of the weight pointed at it the entire time via 4 ads. Like you I'm going to wait and see what happens. I've seen a lot of fluctuation in Y on individual keywords over the last few months but this is the first time they've all been dropped at the same time. BTW here's the kw tool snapshot from the other thread:
pretty much all my sites with coop have lost all their rankings in yahoo pretty much but not all of them, so it could be from something else, or a combination I also lost some without coop weight I actually I just found a site thats doing great in yahoo, with coop weight, maybe its percentage of static vs dynamic links, or maybe another link distrubution type filter.
None of my sites have ever been affected by the COOP in Yahoo and have been using the coop since the start Yes there can be ups and downs but normally back in a week Its a search engine so things do change
