Much has been said of links, but it’s mostly inbound links that get all the attention. Internal links – links that point from one page of your website to another – should also be considered a part of your overall link structure.
Internal links can have a big impact on your overall SEO. There are a couple of primary ways to make sure that you get the most out of your internal links. The first is to ensure that you use the proper anchor text. When you link from page A to page B you should use your primary keyword on page B as the anchor text for your link.
If you do that on every page then you should improve your SEO tremendously. Always use the primary keyword of the page to which you are linking no matter which page you are linking from.
The second way to use your internal links is to make sure they are html links and not dynamic links. Mouseovers, blinking text, and drop down menus are often used as features of navigation bars and they generally work against webmasters where SEO is concerned. The best way to improve your SEO with internal links is to make sure that your navigational bar is HTML-based.
If you do these two things on your website then your internal link structure will be stronger than ever before
