If your using web analytics to improve your site there’s one thing you need to do before you even start looking at the numbers…

Identify areas on your website which don’t contribute towards your site’s goals and try to remove them where possible. These include blank spaces, duplicate content and unnecessary headers. A 1cm margin at the top of your site reduces your content area by 5% on an average size monitor! 

Of course you need to balance design and value, but if a space on your site isn’t adding either then get rid of it. This allows you to bring more content above the fold and focus your visitors attention on the things you want them to see.
