Internal links are links that point from one page to another page on the same website.
Most of the time we neglect internal links and are therefore unable to reap the benefits of internal linking for SEO.
Having a good solid internal linking structure on your website helps a lot as it makes it easier for search engines to locate, crawl and inevitably index the pages on your site as easily as possible.
Not only this but internal linking also helps your audience to find more interesting information on your website therefore also indirectly increasing your site’s performance for visitors that make their way to your site in addition to its performance in search.
The Difference Between Internal Links & Backlinks
Internal links and external links both are vital for search engine optimization and contribute to a large section of off-page SEO.
The quality of your website’s internal links and external links has a direct impact on how well your page ranks in the search results.
Let’s now take a close look at the difference between internal links and backlinks.
As said earlier an internal link is a hyperlink that points to the other page on the same domain. For example: yourwebsitename.com/products/ is linking to yourwebsitename.com/products-q/
With the help of internal links, the users can easily navigate to your website as it allows the relevant content to be connected on your website and maintains a shallow website structure.
A backlink is a hyperlink that points to a page on another domain.
If some other website links to a page on your website then you gain a backlink. If your website links to another website then that particular website receives a backlink from you.
Internal Linking Basics
Internal linking can turn out to be a goldmine if used correctly.
However, too many links will only make your page look spammy which can negatively affect the page’s (or even the site’s) ability to rank.
We recommend adding three or four internal links to your post depending on the length of your post.
This is obviously just a general rule of thumb and obviously there will be exceptions – just write to help users find content, the moment there are so many links that the content is messy and no longer serves a specific purpose, that’s generally a great sign that you’re already way past the number of internal links that’s suitable.
Using Over-Optimized Anchor Text
Let’s begin with what is anchor text first.
Anchor text is the text of your links to your web pages from the authoritative sites generally highlighted in blue and underscored within a sentence.
For example, if I were to link to our guide on Schema Markup – the anchor text of the way I’ve added this link here is “Schema Markup”…
Now, over-optimized anchor text means that there is an insignificant amount of anchor text pointing to a page.
Anchor texts play a vital role in SEO as they help to boost your search engine rankings.
But if they’re not used correctly or they are over-optimized there are chances of your website even being penalized that will ultimately hamper your page rankings.
Avoid Unnatural (Non-Contextual) Internal Linking
Using unnatural or non-contextual internal links will only disrupt the site’s authority.
For example, if you’re using a plugin to link automatically to the pages on your website, it creates an unnatural backlink for those pages.
All of these will have the same anchor text which is not what we’re looking for.
Another thing that you’d not want to overdo is to apply a nofollow tag to the links on your domain. This is another way of unnatural Internal linking that can also get you penalized if done on a frequent basis.
The Concept of Link Equity
Link equity also known as link juice is a process in which the links can pass authority from one page to another.
Link equity can be passed from both internal as well as external links.
How does Link Equity Work?
When we talk about Link Equity, let’s not forget PageRank as this ties in very nicely here and is still applicable to this day.
PageRank was Google’s first algorithm that made use of a website’s backlink profile to determine the search engine rankings.
PageRank functions on the basis that the most suitable content/websites will receive the most links from other websites. And therefore it wouldn’t be an incorrect assumption to make that this is one of many factors to be taken into consideration when choosing which sites should be shown to users in search results.
The concept as it applies to internal linking is that every page has some inherent “value” which it can diversify by linking to too many external sources or also pass on by strategically linking to related content on a site internally.
How is Link Equity determined?
1. Follow or No Follow links
Links that make use of the nofollow tag are not crawled nor followed by the search engines. These links will not pass link equity.
2. Link Relevancy
Links that are not relevant or authoritative will not be of any value to the search engines.
For example: If you link to a website from a bakery page to homeschooling tips, the link is not relevant and Google is smart enough when it comes to understanding the relevancy of links.
Hence it’s important to know that the links will only pass value if they’re relevant and offer some value.
3. Crawlable Links
The link will not pass any value if the page is blocked by the crawlers via the robots.txt file.
4. Number of Links located on the Page
If there are numerous links to your website, then it’s not considered to be valuable. If your link is lost among the sea of links then it’s pretty obvious that the user will not be able to find it thereby devaluing it further.
5. Does the Status Code pass?
Google retains link value through 200s, 301s, and 302s.
How to check Link Equity?
There are various free link building tools that make it possible to check related/somewhat similar metrics, such as Ahrefs and SEMrush which are helpful in understanding this.
