Any link to your domain that does not point to the homepage is called a deep link. These links point deep into a domain in order to link to content there.
What are Deep Links?
Deep Links are mainly used to point directly to a specific piece of content or product without the user having to take that route from the homepage. In terms of link building, deep links primarily strengthen the linked subpages.
How are deep links generated?
For Google, a link is always a link if it is a simple <a> element with an href attribute that points to a specific URL. A deep link, therefore, is a simple link that does not point to the homepage of the domain and has been given its own name in order to make it easier to describe.
Here is an example of a start page link to the SISTRIX start page written in HTML.
<a href="https://www.sistrix.com/"> SISTRIX start page</a>
And here are two deeplinks. The first to the ask-sistrix page, the second to an article deeper within that area of the website.
<a href="https://www.sistrix.com/ask-sistrix/"> <a href="https://www.sistrix.com/ask-sistrix/google-index-google-bot-crawler/how-can-i-remove-a-url-on-my-website-from-the-google-index/">
What percentage of deep links should my website have?
There are no quotas that a website operator must adhere to. The ratio is, of course, determined by the type of website. If the main entry point is the homepage, it is probable that it will have a high number of links pointing to it. If one offers good information on sub-pages, a high deep link value can also arise.
Here are a few examples of large, well-known domains:
Deep links and user experience
Deep links can be an interesting starting point when asking ‘What content on my domain do people like to share?’. A link to a subpage is always an indication that this page has added value for the linking website.
A higher value should, therefore, be placed on the user experience offered by these articles. With these pages, it is also worth thinking about what visitors will find there and how it might be made easier for them to dive further into the website.
