What are the best advertising services for a website?

[Shan]

Your best path is to find an affiliate product that matches the content on your site, such as putting ads for electronics on an electronics website. Serving relevant ads to your target audience is FAR more important than which affiliate network you end up using.

The Amazon affiliate program would work well, or Commission Junction or other direct affiliate programs. I wouldn't use Adsense because the earnings are too low, as you are paid a few cents to send a visitor clicking off to a product site that you would have earned a much higher commission percentage on, if it was your own affiliate ad there instead.

Work smarter, not harder...
