If we can assume that each and every web page is awarded points and these points were distributed to the links on that page according to the significance of those links, that points distribution is denoted as link juice.

As you might imagine, link juice is an expensive resource that you want to cultivate and protect. One great way to protect your juice is to pay attention to your page architecture.

You may be committing a very common mistake that is poking holes in the bottom of your cup and letting your juice pour right out.

Whenever a particular link appears over and over again in a website, the spiders assume it as an extremely important link, and so it is awarded a hefty portion of the juice.

However take a look at your website... Go ahead; take a peek way down at the bottom of the page. Now take a glance at your next page, way down there at the bottom. And the next page, and the next. Are you seeing repetitive links to your privacy policy page? Your terms of service page, your affiliate pages, your sitemap?

Your footer navigation might be a serious source of link juice leak. Since those links appear again and again, the spiders will assume they are important, so you want to protect them from being awarded any of your juice.

The easiest way to protect yourself against this link juice loss is to use NoFollow in your footer, sidebar, or any repetitive navigation. If you desire to get really serious about generating traffic, it is time to get proactive.

Come to a decision that which pages on your site YOU consider the most important (don't put down this critical issue up to the spiders!) and create an information architecture strategy to ensure that your pages are ranked accordingly.
