INTERNAL LINKING FUNDAMENTALS

There are two issues you need to be concerned with in regards to your internal site links.

The second issue is that the benefit that any single page receives from an incoming link is highly dependent on the context of that link - specifically the anchor text (text used within the link itself) for the link.
