How to make money from blogs - Contextual advertising

Here ads relevant to your topic appear on the page and you get paid every time someone clicks on the ad, also called cost per click. Google AdSense is the leading network, but there are others like Chitika or Tyroo. "You can sign up free and then integrate a given code to the page where you want the ads to appear," says SEO expert and Internet marketing professional Saptarshi Roy Chaudhury, who blogs at www.seo-kolkata.blogspot.com.

Manish Vij, co-founder, Tyroo, says, "Selecting the right ad network that suits you and using those words for which advertisers pay more per click will help increase your earnings. You can find which words make more money through trial and error testings."
