Since the other day I am not ranking at all anymore in Yahoo. I used to have many top10 positions but now nowhere to be found in the top1000. Am still ranking quit nicely in MSN/Google. First I thought all my pages got booted, but all 12.200 pages are still in the index, they just don't rank for anything at all anymore. This must be some sort of penalty and on another forum it was suggested that it was due to alot of unrelated links. My site has been using the coop for about 3 months now, so this might be the issue. As long as I am not sure I will not post it in the coop forum, but I do want to know if this might be the case or that it is something else. Website: www.hotelalliances.com Pre Coop : about 2.000 links according to Yahoo Post Coop: about 101.000 Weight new style: 22.000 NR of keyword combinations: 35 Homepage links: 5 different keyword combinations Deep links: 10 different pages with 3 keyword combinations each IMO this is spread out quit nicely and because of the limit of 20 keyword combinations with 2 sites and 5 links to other sites, the limit has been reached. At least 3 different keyword combinations for each page in order not to be seen as spamming the index. I also bought a relevant sitewide PR6 and a relevant PR8 in the last 2 months. Before that most of the links were reciprocal, ranging from PR0 to PR5 and about a 100 or so links from different directories, PR ranging from 0 to 5 as well. If you have any idea as to the cause of my site not ranking anymore and/or have any suggestion as to how to get the rankings back that would be greatly appreciated! PS: pre coop rankings were many top20/30, so it is not like my sites ranking have referted to its previous place, the rankings have just completely dissapeared.
