I now have a total of 6 of my wiki sites/buffer/article2.0 ranking on the top 2 pages for my term, and the MONEY PAGE nowhere in the top 100
I experienced the same yesterday - here is my case:
4 year old domain (quality moneysite)
I've optimized for one page the last two months using web 2.0s only (blasted a few of the web 2.0s, but mainly web 2.0s that stood alone)
The 2.0s contained spun readable content (nothing fancy).
Each KW I went for had around 50 2.0s pointing to the site with the same anchor.
Been doing it for around 2 months. Adding more KW runs to the mix.
Yesterday all the ranks got wiped out relating to the KW's I've optimized for. The moneysite retained the normal ranks. Only the rankings obtained by the 2.0s got obliterated.
What happened? It looks like I've overoptimized the anchors. No variation. I've used the same technique on two other sites. They have not been hit, but I haven't made that many 2.0s to them yet, so perhaps they are under the anchor diversification radar.
Which brings me to the solution:
Either change the anchor on 60% of the 2.0 that I've created (they are indexed and many of the rank in top 100) or create new Web 2.0s with only non kw anchors (click here, check this etc.) or blast some social bookmarks at the site (also with non kw anchors).
So what do you guys think? Should I redo the 2.0s, or blast new anchors to the site?
