How many internal links should an article have to optimize its SEO? This is a recurring question among those looking to improve their web page rankings. However, the answer is not as simple as a specific number. According to Google, there is no magic number of internal links per page. What we do know is that internal links are crucial for helping Google understand your site’s structure and prioritize the most important pages.
The Importance of Internal Linking According to Studies
Internal linking is, according to Google’s John Mueller, “super critical” for SEO. This type of link helps Google discover new pages and indicates which content is more relevant within a site. A study by Zyppy analyzed 23 million internal links and found that more internal links correlate with higher traffic, up to a point. The idea is that each important page receives at least one incoming internal link, so it doesn’t become isolated as an orphan page.
Imagine a site with hundreds of pages. Without good internal linking, many of those pages could get lost in digital oblivion. In fact, Ahrefs’ analysis suggests that many pages are under-linked, receiving barely one or no internal links. Therefore, it is critical to review and optimize internal linking to not miss out on this opportunity to improve traffic.
But don’t obsess over reaching a specific number of links. The key lies in the relevance and context of the link. Google suggests that if a page seems to have too many links, it probably does. Instead of focusing on a number, focus on creating links that truly add value to the user and the search engine.
Are There Ideal Numbers? Debunking Myths
It is often mentioned that having between 40 and 44 internal links could quadruple a page’s traffic. These figures come from simplified interpretations of Zyppy’s study, which analyzed 23 million links and concluded that the optimal number of links depends on the type and length of the page. It is important to clarify that this is a correlation, not a direct causation.
Google has been clear: there is no ideal number of links per page. The recommendation is to use common sense. If it seems like there are too many links on a page, there probably are. What matters is that each link has a clear purpose and is well-contextualized.
In practice, the variation of anchor text also plays an important role. Zyppy found that a greater variety of anchors can correlate with more traffic, but it must be natural and not forced. In summary, don’t get carried away by magic numbers; focus on the value and relevance of each link.
Internal Links in Your Site’s Structure
The structure of a website matters for SEO. Ahrefs recommends organizing content into thematic clusters, where a pillar page is linked from several specific pages. This approach reinforces thematic relevance and improves user experience by facilitating navigation.
The site’s hierarchy should be clear and accessible. Keep important pages a few clicks away from the main page so that Google considers them relevant. Click depth is a factor that Google takes into account when evaluating a page’s importance. The closer a page is to the home, the better for its visibility.
Additionally, avoid simple reciprocal links, which can appear as artificial exchanges. Instead, opt for triangular linking, which distributes authority more organically. Remember that good internal linking is not just about quantity, but about strategy and planning.
Common Mistakes in Internal Linking
Despite its importance, it is common to make technical errors in internal linking. One of the most frequent mistakes is using UTM parameters in internal links, which can distort analytics data. These parameters are useful for external links, but for internal links, they muddy traffic attribution.
Another common mistake is using generic anchor texts like “click here” or “read more.” These do not provide context to the user or Google about the destination page. Instead, use descriptive and relevant anchors that clearly indicate what the linked page is about.
Ensure that all links are crawlable. Google only follows links that are HTML elements with an href attribute that resolves to a real URL. Simulated links with other elements may not be interpreted correctly, affecting the effectiveness of internal linking.

Internal linking is a tool to improve SEO, but its effectiveness depends on careful and strategic implementation. Although there is no magic number of links per page, the key lies in the relevance and quality of the links you create. Always keep in mind the user experience and the thematic structure of your site when planning your linking strategy. In the future, internal linking automation could make this task easier, but common sense and best practices will remain essential.
