Ive heard allot recently about over optimisation regarding backlink anchor text ofsite.

What ive heard from seomoz was sites most effected by the penguin update had over 60% of their backlinks anchor text the same, so google saw this is unnatural and penalized them. Which kind of makes sense as its not normal to have such high density on one word / phrase.

If i where building links for a gastro pub in london. (this is purely hypothetical).

The sort of keywords i would go after are "gastro pub in london" and "london gastro pub"

If i where to mix up the anchor text by having:

• gastro pub
• gastro pub in london
• london gastro pub

would this be seen as ok ? or would these all be seen as broad match keywords and counted as one phrase, making me fall foul of the penguin update ?
