Best Internal Architecture for SEO

Internal linking should also be done with the help of in-text link rather than navigation menu.

What’s the difference ?

Navigation Menu	In-Content Links
Consists of sitewide isolated links that carry less SEO weight.	Are links in context that allows search engines to learn more about the destination page.
Offers more control over website internal structure: you don’t need to think much of internal interlinking once you set up your navigation.	Are more spontaneous (more difficult to manage) but offer full control over internal anchor text.

To my mind, in-content links are not going to replace navigation menu completely (after all, there is nothing better from usability point of view and it can be easily and thus effectively managed). The point of this post is to encourage webmasters to experiment moving some of your links from the navigation menu into the content area and also to try the following:

* breadcrumbs;
* “related categories” and “related articles” blocks;
* different navigation menu for different page types; etc.
