not to fret bloggers! There are other alternatives to Google AdSense. Using the same concept, which is contextual advertising, many advertising websites have started that are not as strict as Google AdSense.

1) AdBrite (has only content requirements)
4) Clicksor (sometimes shows irrelevant adverts)
There! Enjoy earning income even without Google AdSense! Anything to add? Comments below!
