Kontera is proving to be a significant source of ad revenue for webmasters. It is a contextual ad program for websites. It is a cost-per-click (CPC) ad program - you earn when a visitor clicks an ad. Kontera uses a new concept of advertising called in-text advertising, unlike the banner ads or text link ads we are used to. Contextually relevant keywords on a page are double-underlined that on mouse-over loads a tool tip box containing the ad - they call it Contentlink.

To get in, you need to have a website with a lot of text content and 250,000 page impressions per month. Its a good thing that they are accepting publishers from all over the globe though the primary site language should be English. However, quality sites with less traffic can also make their way in by reference. For example, I signed up as a “friend of Joel Comm”�. John Chow also has a similar understanding with Kontera.

Kontera can be used by webmasters in conjunction with the most favored Adsense or any other contextual ad programs. Webmasters are looking at it as an added source of revenue to supplement their income from Adsense.

The more traffic you have the better. Great content will help too. The revenue will start generating after the initial 2 weeks during which your site will be optimized. I have started using Kontera on Niponwave (monthly page view 1.5 - 2.5 lacs) recently and my account balance reads $54 after 51 days out of which initial 14 days went for optimization and did not yield much of revenue.

Publishers are paid via checks in US dollars once the earning reaches $100.

So why wait? Apply to Kontera today and watch your revenue grow!
