One best practice for SEO that trips up a lot of new search engine optimizers and webmasters is internal domain linking. It’s not difficult and to a large degree the methods are similar to those of building inbound links.
The search engines look at several criteria for determining the value of an internal link. They are basically the same as those for inbound links.
- Relevant anchor text
- Authority of web page linking out
- Age of domain
- Age of link
- Number of links from the linking page
These are just a few of the criteria search engines use to judge internal links, but they are important criteria. The most important one, of course, is link anchor text.
How Internal Link Anchor Text Works
Your website likely covers a broad topic. That’s usually the case. But each web page on your website covers a specific topic within the broad context of your niche. Let’s say your website is about 1950s fashion.
Within the broad purvue of this topic you could write about hairstyles, shoes, bobby socks, men’s fashion, and women’s fashion, just to name a few.
So let’s say your page on women’s fashion makes a mention of bobby socks and you have a page on footwear that has a subsection on bobby socks. You could use the text “bobby socks” to link to that footwear page and that’s good anchor text. To narrow it down further, you could create a bookmark on the subheading of the section on bobby socks and link directly to that bookmark. Voila! You have great anchor text for your internal link.
Number Of Links Per Page
When linking internally, you have to be careful how many links you add to a single page. The page authority for your outbound links will be distributed evenly among all the links on a page. So you want to make sure that you link between your pages optimally – not too liberally. But you do want some internal links.
Just as websites have authority, individual web pages have authority. The authority of each of the web pages on your website are intrinsically linked to the overall authority of your website within your niche. If your authority is relatively high compared to other sites within your niche, then your internal links will have great weight attached to them. That’s not to say you shouldn’t build inbound links from other websites. You should, but I’m just speaking relatively.
When you build internal links for SEO purposes, also be sure that add value to your website users. If a link doesn’t make sense for usability, then it probably won’t make sense for SEO. Don’t spam the search engines with useless and non-valuable links, internal or otherwise.
