And that was that our client asked us to re-post his blog articles elsewhere for additional traffic. I posted them on Squidoo, since I know it well and could set it up rather easily. Most of the keywords I used over and over again with each publication took a major hit, while some of his lower volume keywords that I skipped remained on the first page.
I'm going to go unpublish all of those Squidoo reposts and see what happens. Worse case, nothing happens - but I do find it interesting that the only site we manage that took any kind of hit was one where we were reposting published blogs too.... (keep in mind that the rankings were quite good as of Monday)
Anyone else have similar indicators?
