how many links to your page from another page should there be. Example say you have 5 keywords should I ask for 5 different links with different anchor text pointing to my page or is one enough? Does to many hurt your ranking?
Using different keywords/anchor texts is a good idea. Not only you can promote with more keywords, but also to let Google think your links are natural. Many think that G seems to know too many links with the same anchor text are rather artificial.
one use one link from one page to another....using five with five different anchor text is obvious spamming
