This is a newly emerging but extremely targeted and effective form of promoting your online business. Consumers download specific software from a contextual marketing network organizer at no cost and install it on their desktops. When the consumer is about to make a purchase for a specific product or service or is placing a search query for that item, the software will beam advertising messages from suppliers of that product or service, offering some incentive to the consumer such as discounts or promotion offers. Through this facility, the advertiser (supplier) is getting an opportunity to promote his offering to a targeted consumer and that too at the point of sale or when there is an intention to buy. Thus contextual marketing offers a highly targeted marketing tool that connects the supplier with a genuine lead and spurs transaction.
The effectiveness of contextual marketing can be seen from the fact that response rates and conversion rates are from 5 to 20 times higher than the results from conventional online advertising.
Here’s how Google AdSense applies this concept.
Google AdSense is a fast and easy way for website publishers of all sizes to display relevant, text-based, un-obtrusive Google AdWords ads on their website’s content pages and earn money. Because the ads are related to what your users are looking for on your site, you’ll finally have a way to both monetize and enhance your content pages. The program is free, and Google pays you for clicks on the AdWords ads on your site.
There are no strict criteria for acceptance into the AdSense program, which, unlike other ad networks, does not place minimum traffic requirements on applicants. The only real criteria are the standard “acceptable content” requirements that exist just about everywhere. Of course, AdSense wants to attract quality content sites, and will only allow AdSense members to serve one ad per page – the service can’t be used for both banners and skyscrapers.
Once you’ve been accepted, you’ll be able to run AdSense advertisements on any site you own using the same ad code, provided you obey the guidelines. Reporting doesn’t occur in real time, but is updated regularly throughout the day. Currently, you cannot view reports based on a domain or site basis if you run the ads on more than one site.
This is what Google says about what makes AdSense different from others
This innovative new Google business solution will help you unleash the true revenue potential of your site.
