What are Ads and Banners?

Ads and Banners are simply pre-sized adverts (looking something like small stickers) that you stick to your website in key locations. They may be Pay Per Click (PPC) revenue generators or they may require the site user to make a purchase on the site clicked through to. Either way, an identifying tag embedded in the Ad or Banner will identify that that purchaser was directed to the site through your site, and a commission may be payable based on a flat fee or a  percentage of the purchase value.

Ads and banners may be text, pictorial or a combination of both and also static or contain dynamic content, as in the examples on this page.
They tend to come in standard sizes (although this is not always the case) to make website designs easier and cleaner.
Common sizes, in pixels, are: 300x250, 336x280, 728x90, 160x600, 468x60, 234x60, 120x600, 120x240, 250x250, 200x200, 180x150 and 125x125.
