Google provide some very useful guidelines on fine-tuning your AdSense campaigns.

Remember that:

1. AdSense works by crawling your web pages for content.

2. It delivers ads based on that content.

Help Google Crawl your site

So, if your content is limited, its crawler may have difficulty identifying the information on the page.

This means that you may see ads that are not directly relevant to your page or public service ads. You need to create more compelling, focussed content.

How to get Google ads that match your site

Do this:

1. Ensure that your pages are full of compelling content.

2. The more targeted, text-based information you provide, the easier it will be for Google to determine what your pages are about — and the greater the relevance of the Google ads.

Here’s a simple equation from Google:

1. A content-rich page = Highly-targeted ads
2. Highly-targeted ads + Interested users = Healthy click-through & conversion rates
3. Healthy click-through & conversion rates = Success!

Remember – you can also use page section targeting to focus our crawler on certain sections of your page that may be more content-rich than others.
