I have lost some rank on quite a few sites over the last 2 months - and although many are saying Panda 4.0 I also personally think there is something to do with links as well brought in with this update.
The only possible 2 things I can see which might adversely affect the sites as regards links are:
Sitewide Links - I have a couple of sitewide links which have been used which is a directory site & niche related but with generic anchor text - i.e visit website ?
Could this be an issue does anyone think ?
Anchor Text - Havent even used same anchor more than once but seems that naked url's seem to be doing the trick now more than anchors ?
