How Many Hits Are You Getting?
Some engines also consider ranking based on how many times users have clicked through on your listing. Imagine that your listing on a search engine has a counter on it. Sites with the most click-through’s will tend to have higher ranking. After all, they are clearly more popular.
The bad news is that there is not much you can do about this. Trading links and optimizing your site will have no direct effect on this value. However, the good news is that this type of ranking is not used by many engines, and doesn’t have an enormous effect on ranking… but it is certainly worth noting.
