Internal Links Versus External Links
Internal links are links that go to other pages of your own website. External links are links that go to pages that are not part of your website. In other words, other people’s websites.
Internal Links Should:
- Use keywords as anchor text
- Be interspersed with the content of your site
- Interlink between pages of your site that are related to each other
- Open in the same browser (i.e. don’t use target=”_blank” in the URL code)
- Be “dofollow” (i.e. don’t use the rel=”nofollow” in the URL code)
How to build an internal link
A typical link looks like this: <a href=”URL”>ANCHOR TEXT</a>
To build your link, you would replace URL with the URL of your web page and replace ANCHOR TEXT with your anchor text. Of course, you would want your anchor text to be a particular keyword related to the page you’re linking to. If you’re not familiar with this concept, please review choosing your best keywords.
If you didn’t notice, that link we just used there is an example of an internal link. It’s linking to a page that is related to this topic, using the anchor text: “choosing your best keywords”. When search engines crawl this page, they’re going to find that page too because of this internal link. It also adds additional relevant content for our readers.
Sitemaps as a Form of Internal Linking
Using an XML sitemap for search engines and an HTML sitemap for your human visitors is a great way to create strong internal links for your website. We’ve got an entire video dedicated to creating a sitemap (there, I did it again…another internal link).
