Should one vary anchor text as to imply natural link progression or use consistent anchor text to build and imply keyword strength? I personally have been varying anchor text lately your opinion...
I would try to vary your anchor text as much as possible. Less of a chance of tripping a filter and you'll get more traffic from the different anchor text.
If you have some keyowrds need to get good position; ANCHOR TEXT is plays main role in ranking factors. And vary the anchor text with keywords pointing to your website. Lets say example ... If you've three main priority keywords - KW1, KW2, and KW3 Try to get the inbound links with anchor text KW1 and description DS1. Once you get 20 inbound links with KW1 anchor text, then chagne the anchor text to KW2 and DS2 (a small change in DS1). And get another 20 inbound links. After 20 link go for KW3 & DS3. So that you will get enormous number of links with diffrent anchor text and description. Good Luck !
One of the important reasons to vary anchor text is that different text could attract different clicks. Internal links using varied anchor text can increase the number of visitors that click through to a given page. That works well when you have more than one link to a page on any other given page. For instance a link in a standard site navigation block and a link in the text on the page.
