Hello! In last month, I lost my best 3 sites... They were in first pages on keywords, I getting few backlinks daily from profile/dofollow blogs/sites. Now sites are in 100,69,7 page on keyword... Why ? A lot of work and nothing
Tripped a filter -Over optimisation of anchor text? Are all your links SEO Anchor text? - If so sounds like that to me. IF 90% of your links are 'red widgets' then tripped a filter, build more www's etc etc FS
