Vanessa Fox has a wonderful post on her blog called “the power of search: driving traffic to your blog (a BlogHer recap)”
I was just going to bookmark it to read later, but I started reading and finished the whole thing, it’s pretty long. She talks about how people find your blog in clear terms that even someone who is a casual observer could understand. I think it’s a great post that I’m going to recommend.
Vanessa recently left Google so she has some relevant experience to share and even though she says she is talking about blogs her advice really applies to any part of your site.
