Recently we had the well-known and discussed traffic power ban and now it looks like a big name SEO company based in the UK has been banned from Google. I have never heard of them, but the forums are buzzing about BigMouthMedia being de-listed from Google. Several current searches show that BigMouthMedia not listed as #1 for its own brand name, also no results for the site command.
Ammon Johns at Cre8asite asks; "is this a new sign of aggressive defence of its algorithms by Google?"
