What is the meaning of anchor text penalty?

[web2smspk]

If i have 70% back links with same anchor text, will i get penalized? some of my blog's pages which were previously in top 100 in google are no where now. but for other long tail keywords, m still in same position. How to get rid of this penalty?

Should i create more links with different anchor text to reduce the effect or should i remove that 70% back links?

Basically it's unnatural to have 70% the same anchor text, Google will most likely penalize you. Just reduce the % and create more high quality backlinks with a variation, mix it up, make it look natural, 'click here' 'more info' and so on.

Hope this helps, there is more information out there, it's to do with Penguin I believe.
