I have a site that had been on 1POS for all it's keywords for the past year. I was adding unique content each week. My site had very good links (wikipedia, linkedin, Whosington post, Etc..) In the last two month, I went down for more then 50% in traffic and going down to POS 5-7 on search engine results. I went to google webmastertools and I saw more then 10,000 links were made to my site, most of them are comments links with my original keywords linking to my money site & money pages. Moreover, I've noticed that most of the links were created at the same date (by the date next to each comment on each spam link) and I noticed one of the comments had the same username that was used to do a good SEO to my competition, so I guess that he is doing the Negative SEO. (he is now ranking 1#-2#) I've already disavowed those links but my site keeps going down each day & I'm getting new links each day that I need to disavow. What Can I do to recover from this? Maybe I should send an email message to google webmastertools team? Have someone here recovered from such an attack (large amounts of spam links with the same anchor text that you are trying to rank)? I need your help mates!
