Can I Choose My Adsense Ads?:
AdSense ads on your website or blog can deliver high click-through rates, resulting in high income for you because they are Contextual Advertisements This means the ads displayed are what the reader is likely to be looking for. How does this happen?
The robot from Google (or Yahoo Publisher) finds keywords on your page and works out the topics covered then delivers links that take users to related sites that are very likely to interest them. This is a clever and sophisticated technique - BUT if the ads do not link to your keywords you will not be making the $000s per day that so many people are boasting about.
