My main site has A LOT of exact anchor text links for the keywords I was targetting. The site used to be ranked near the top for some very competitive keywords. These links were generated over a period of 5 years or so, and the majority are exactly the keyword I was targeting (with one in particular having more than half of the total incoming links). Now, after the latest Google updates I've lost nearly all of those rankings. Initially I just waited it out and hoped they'd come back... they never did. So my question is, if you have an authority site like this and believe the reason for your drop in rankings to be link diversity, what would you do to improve the situation. What kind of links would you try to get, and what kind of anchor text would you use ? I want to try to get back the rankings I had before, but I'm hesitant that just blasting a bunch of irrelevant 'click here' or a naked URL will actually be worth the effort. Anyone have any positive experience with improving a site like this ?
