" Watch your server logs - I have noticed that sometimes I will just mention something in an article for one sentence that brings in a lot of visitors so I go and write an entire article on that subject. The results have been stellar. You've been given a big hint that people are interested in this and if you ignore it you are missing a big opportunity. I have more than a few articles that have been linked to all over the web because they are almost the only decent material on this subject.
Write content that is as specific as possible. Don't write an article that is super long unless it is necessary. If you can break it up if it seems logical to do so." Atomic
