Clicksor is yet another alternative to Google Adsense. They ranked within the top 100 on Alexa in October 2008 and May 2009.
By centralizing advertisers and publishers on one network, Clicksor selects advertisements most relevant to publishers’ content and places the ads accordingly. This is commonly known as contextual advertising. Clicksor first scans a publisher’s page to find keywords that describe the content. Next, they will match these with advertiser-provided keywords so only advertisements related to the page content will be displayed.
As with any PPC program, the success you achieve with Clicksor will be directly impacted by the amount of traffic your website generates.
