Internal linking is the process of linking between two pages on the same website. External links are links from one website to another. Both internal and external linking is essential for SEO, and they can help your site rank higher in search engine results pages (SERPs).

When it comes to SEO, there are many things that go into getting your website ranked as high as possible. One of the most important is link building. But what are internal and external links, and why do they matter?

In this article, we will discuss the basics of both types of links and explain why they are so crucial for your website’s SEO. Thanks for reading!

Internal Linking in SEO

Internal linking is when you link one page on your website to another page on your website. It is important for two reasons. First, it helps search engines understand the structure of your website and find new pages. Second, it can help improve the ranking of individual pages by spreading link equity (or “link juice”) around your site.

There are two main ways to link pages on your website internally. The first is to do it manually by adding links in the text of your pages. The second is to use a plugin like LinkWhisper, which will automatically add internal links for you based on the keywords on your page.

However, it is better to create the internal links manually, as this will give you more control over the link equity. For example, if you want to promote a specific page on your website, you can add more internal links to that page from other pages on your site.

External Linking in SEO

External linking is simply adding links from your website to other websites. It is done to direct your readers to other sources of information that may be relevant to them. External linking is also a great way to build relationships with other website owners and help search engines to get a better idea of what your website is about.

There are a few things to keep in mind when adding external links to your website. First, make sure that the links you add are high-quality and relevant to your readers. You also want to be careful not to overload your website with too many links, which can actually hurt your search engine ranking.

External linking is a great way to improve your website’s SEO, but make sure you use it wisely. You can utilize tools like SemRush to help you discover external linking opportunities.

What are Nofollow and Dofollow Links?

When it comes to external linking, you may have heard of the terms “nofollow” and “dofollow.” These are actually HTML tags that can be added to links to tell search engines what they should do with those links.

Nofollow links are links that tell search engines not to follow them. It means that the search engine will not count the link as a vote for the website that it is linking to. Dofollow links, on the other hand, tell search engines to follow them and count them as a vote for the website that they are linking to.

Most external links are dofollow by default, but you can add the nofollow tag if you want to. For example, if it is an affiliate link, you may want to add the nofollow tag so that search engines do not count the link as a vote for that website.

Dofollow links are especially vital for SEO, as they can help improve your website’s search engine ranking.

What is a Backlink?

A backlink is simply a link from another website to your own. Backlinks are one of the most critical factors in SEO and can help improve your website’s ranking on a large scale.

While creating backlinks, you’ll want to make sure they’re coming from high-quality websites. There are a few factors that go into determining the quality of a website, such as Domain Authority (DA), Page Authority (PA), and MozRank.

When done correctly, backlinking can be a great way to improve your website’s SEO and help it rank higher in search engines.


Internal and external linking are both important for SEO. Internal linking can help improve your website’s ranking by spreading link equity around your site, while external linking can help search engines decide the quality of your pages. Be sure to use both of these wisely to get the most out of your SEO efforts!
