I'm a web designer and I've built a ton of websites and want to start linking to my website for a keyword. I try to get a link to my website on every site I built. My question is, should I go back to every website I've built and change the anchor text to the keyword I am going for? Right now it is just the name of my company. Or is it bad to always have the same exact anchor text in every link? It's not black hat so there's nothing fishy going on. Also, will the fact that the only links I have built to my site are homepage links be negative? Does Google like link diversification on different types of sites? Like blog comments, articles, etc.
