Everybody who has professed to know anything at all about search engine optimization knows about link building. Every single one of them will give you a list of ways to build links to your site (or how they will do it for you) to help your site to gain authority for its keywords.
All of them will talk about getting links to your site’s home page. Some of them will talk about getting links that point to your internal pages. How many talk about building internal link nets within your own site? Not many of them. Why not? The fact is that not a lot of people know how important they really are.
Building internal links within your site is actually very important for a number of reasons. Not only do they help your visitors to easily navigate to areas of your site where they can find the information they want, but they help you to be able to guide the search engine crawlers to the content you want them to crawl. The biggest advantage, however, in terms of SEO is that they pass authority.
If you have a few posts that the search engines don’t seem to want to notice, try linking to those pages from other pages that the search engines do like. Before long, you will likely see that those pages have suddenly gained favor. You may even see some that have gained PR in the next pagerank update without any external links pointing to them. That PR was passed to them from the other areas of your site. That’s how internal linking works.
Now, go do yourself a favor: go grab a plugin like “SEO Smart Links” and install it on your site. Set up the “Custom Keywords” to link your keywords to the posts that you wrote to target those keywords. Every time those keywords show up in one of your articles the plugin will link them to the appropriate post. It won’t take long to set up, and your internal link net will be done.
In order to thrive, an internet business needs any advantage it can get. Internal linking will not take the place of good, old-fashioned external backlinks, but it just could be the edge you need to push your site to the top.
