The ones that are spammy are easily identifiable as they use 3-4 particular keywords (i.e. over optimized anchor texts).
Now that I have a list of over 1200 such backlinks most of which are spammy, should I delete all of these spammy ones? These backlinks are usually comments at a blog which offer nothing of value (no wise good comment) but just say something vague and post a link to our site.
So what should I do now? I am a bit perplexed on whether I should remove all of these (by requesting the webmasters first and then by google disavow) or if I should leave some of these? Not that it makes any sense to leave them but also concerned about our traffic as our traffic has already dipped from 4000 impressions to 1000.
Please let me know your views. Thanks
