Too many people concentrate on placing the Adsense on their website and then posting their content regularly.

This is of course very good practice - but not enough. You also need to rank high in search engines to get traffic and also think of any other way to get traffic

One of the most important routine tasks to do for your Google Adsense sites or blog is link building. You need build links to your site.
Links are needed to:


increase your Google PR so that you can sell one way links from your website
increase in traffic coming from other sites
make your website rank higher up the rankings especially with Google as backlinks has a great weight of importance




Your links should not come from link farms or any other unnatural ways. For example, getting thousands of links in one month is unnatural. What you need is to build the link naturally which means slowly.

The more links you have which are of high quality and with high PRs, then you will have more of a chance of ranking high in the search engines.
