No matter which ad program you decide, how you decide to put your ads, how you decide to write content or whether to use press releases or not, you must have some way to measure the performance of your chosen methods.
Luckily, you do not have to work very much to be able to track the success of the conflict on your web pages. This is because these programs provide free reporting and tracking for you. All you may want is to set up different areas or channels to monitor one page from one or more policies.
Area
Applications like Adbrite offer a way to set up different areas, even on a single web page. Then they track revenue in the areas too, so you get a good idea of what type of format, what kind of placements works best on your site. They are territorial interests on your web pages that define separate reports and revenue measurements based on what is clicked in that area, regardless of the format or type of ad.
Even if you do not have this option or you were using another application, you could simply decide that the top left is where you place affiliate offers, the center is where you are going to put the main ads and left about it will be its own direct sales products. By monitoring revenue from each of these streams of revenue, you must get a good idea of what ads placements work better for you.
