Hi,

As far as I considered through Penguine update Google is more concern about keyword spamming so:

The site which has so many links with same keyword has been penalized or hit by Google.

The website lost their rankings and traffic too.

As it is tough for websites to recover from Penguin hit.

You should make variation in anchor text according to penguin.

Have you read this case study. Penguin Analysis: SEO Isn't Dead, But You Need to Act Smarter | Microsite Masters

I've seen sites post Penguin ranked in #1 position in Google even though they have no anchor text links at all targetting that keyword. It seems anchor text over optimization is a key factor although it might be combined with on page factors also, so if you are above a certain keyword density and have xx number of links in relation to other anchor text keywords.

Thanks guys for the suggestions....I will take that...
