Amount of Internal Links?

[BrianBotts.]

Does anyone know how much internal linking is helpful in ranking? And, what is the recommended amount of internal links in a page of the website? I have seen some websites adding so much internal links ranking good but not sure about the recommended amount.

There's really no recommended number but yes, they are pretty important.

You can check out the Zappos site and look at how they interlink. It's not excessive but still adds to what the user needs or wants to see during their stay on the site.

The unofficial best practice is 100 as the upper limit but in the end I'd try to think of it more from the context of how the weight passes between pages and how you want the engines and users to prioritize your content.

I actually wrote an article on this exact subject some time ago on Search Engine Watch where I show the math and how site structures to pass weight differently.  That's probably a better answer that a flat number without reason so if you're interested you can see how the weight flows with diagrams at http://searchenginewatch.com/sew/how-to/2179376/internal-linking-promote-keyword-clusters.

Hope that helps and let me know if you have any questions.
