Hi Geoff.
1. These are not websites I own, I had asked the webmaster to remove these site-wide links which they did.
2. They are not hosted on the same server.
3. The anchor text was keyword specific.
4. As a preventative measure, however it looks like this has back-fired.
5. Not to my knowledge, check PR and all is still the same.
6. Yes, they do have other links pointing to it, however in terms of percentage very little, as these were site-wide which was going into the thousands.
Some keywords have disappeared that were not in the site-wide links, which is a concern, maybe there is something else going on?
Shall I get the webmaster to re-instate these site-wide links?
