Anchor Text, quotes from famous SEO guys

-Aaron Wall: “You can see how powerful this just by testing adding a new related word or two in your inbound anchor text and see how quickly you start ranking for phrases including that word.”

-Eric Ward: “Multiple factors play into the ultimate effect of anchor text. The best anchor text in the world is meaningless if the site has not shown previous signals of trust.”

- Peter van der Graaf: “As long as it doesn't look spammy, having perfect anchor text is easy SEO”

-Hamlet Batista: “Keyword rich anchor text still remains a very important factor, but links with URLs or brand names are important to have too.”

overall interesting quotes. I think any experience seo can say something like this.
