It’s no big secret that search engines have an affinity for blogs, websites that incorporate blogs, etc.
Case in point:
A Google search conducted for the name “John” yields some interesting results.
The first position belongs not to John McCain, John Lennon, or even the Gospel of John. No, the first position is currently held by John Battelle, founder of Federated Media and author of Searchblog.
More proof of the weight that Google’s search algorithms place on the frequently updated content that a blog can provide.
