Internal links or "internal linking" are linking whose function is to redirect the Internet user, not to an external site, but to the pages of the same site or to another place on the page thereof. Not only do they help the site rank well on search engines, but they also help improve accessibility and the user experience by making navigation easier. These links allow navigation from the home page to the various pages of the website. When the site does not have optimized internal links, resulting in smoother navigation for users, the content they are looking for will be difficult to find. As a result, the site's bounce rate increases. In other words, the visit path of Internet users to the site is limited to one page. For your information, links are said to be external when they point to the pages of another site. While these two kinds of links are all useful for ranking, it is recommended that you start an SEO strategy with internal link optimization.
The use of internal links makes it possible to identify the links between the content of the pages of the site, to disseminate the value of the link to its pages, to improve the indexing of web pages, and also serves as a guide for user navigation.
Building connections between the pages of your site is essential to allow Google to better explore it. The search engine uses the content relationships to rank the site.
Internal links are important as they help build the authority of your web pages. So, when the content doesn't have links, it is seen by search engines as less relevant.
Content relationships allow search engines like Google to determine the value to assign to a link. The creation of several internal links thus maximizes the chances for a better ranking of your content.
The foundation of your content should be solid, that's in a nutshell what sums up Cornerstone content. The "cornerstone content" will allow visitors to better familiarize themselves with your website, the offers you offer and the various subjects you discuss.
It is not necessary to link every piece of content that contains a similar keyword. The links you use must always be relevant to the subject, therefore descriptive and relevant. You must then include links that will inform and entertain the user.
For newbies, anchor text is a link embedded in a keyword or phrase. It should be used as naturally as possible in the same way as your binding structure.
Like keyword misuse, filling in content with internal links is considered spam and should therefore be avoided. You should only link when it is relevant in the content.
As a reminder, the home page has the most authority. Some will tend to build multiple links pointing at it. However, you should also think about linking your other content in order to direct users to the other pages of your site: FAQ page, about page, video content, etc.
It is clear that the use of internal links contributes to the success of a website. Thanks to these key links, the content of your site will obtain a good ranking on the search engines, and Internet users will be able to navigate easily through the pages of the site. Internal links therefore play a key role in the optimization of natural referencing and allow a better user experience.
