Hi, I run a small gaming site as a hobby, and I was thinking of making some money just to at least cover my server costs with advertising. And when I look at my stats I see that there is such a thing as "visits", and there is such a thing as "hits". Also when I was looking around the Internet to see how others do advertising, I saw that there is such at term as "impressions". So what I was wondering is what does each one of those terms means?

Thanks

visits = unique visitors to your site

hits = graphics and such.. all requests..
[one user can have 100 hits.. etc.]

what he said ^^

hits are counted as each item that loads from your page. if you have 100 images, one user loading one page would probably generate alittle over 100 hits. (depending on how much stuff had to be loaded)

impressions are how many times a banner is shown.. like if you were selling banner space for "x" amount of impressions, each time a visitor opened the site and their banner came up it would equal 1 impression.
