The easiest way to place advertising on your own web site is to join free adsense programme from Google.
There is also a similar programme run by Yahoo, but I suggest you start with Google Adsense because it is so easy to set up.
Google Adsense allows you to place adverts from thousands of potential advertisers on your website with minimal effort because the whole process is largely automatic.
The Google Adsense ads are 'contextualised' which means thatgoogle scans your site and finds out what it is all about and then only places adverts on it which are relevant. This is good news for the webmaster, because relevant ads are more likely to be clicked and therefore make money. When you change your content, the ads automatically change too. As i said, it really is very easy.
You can also customise the appearance of your Google Adsense ads to fit in with the look and feel of your website. This is important as how the ads look will have a big effect on how many clicks are made by visitors.
Getting started is fast and easy. To be perfectly honest, there is no reason to wait any longer. Apply for an adsense account today and within a week you could be earning money from your website.
The interface provided by google is excellent and they keep providing new tracking functionality to improve your understanding of how much money your website is generating for you.
