Does the position of an internal link on the page really affect its SEO weight?

Does Google handle a link differently based on its position in the DOM?

The official answer is no. A link placed in the footer theoretically has the same weight as a link in the main body of the page. This statement from Mueller breaks a widespread belief that search engines would favor contextual links over global navigation links.

In practical terms, this means that Google analyzes the structure of links independently of their location in the source code. A link located at the bottom of the page, in a footer section, theoretically conveys as much value as an editorial link that is at the heart of a paragraph. This approach simplifies the reading of the link graph but raises questions about contextual relevance.

Why might this approach seem counterintuitive?

In actual user behavior, a link in the main content generates more clicks than a footer link. SEO professionals have naturally developed the idea that search engines would reflect this difference in engagement in their link weighting algorithm.

But Mueller separates two issues here: the calculation of internal PageRank and user engagement signals. A footer link can pass SEO juice without generating traffic. These two metrics do not necessarily overlap, and Google seems to treat the passing of link value quite mechanically, independent of UX.

What about image links and anchor text?

The second part of the statement is equally important. A link placed on an image uses the alt attribute as substitute anchor text. If this attribute is absent or empty, Google has no semantic context to interpret the link’s destination.

This is a common mistake: entire websites build their navigation on images (clickable logos, product thumbnails) without a descriptive alt tag. The engine then reads a “blank” link in terms of text, which essentially wastes an opportunity for semantic enhancement of internal linking.

• Link position (header, footer, sidebar, content): little to no direct impact on transmitted SEO weight
• Anchor text: a decisive factor for Google’s understanding of the link destination
• Image links without alt: equivalent to “blind” links semantically
• Optimizing every image link with a relevant alt becomes a priority for internal linking
• Don’t underestimate the importance of position in the DOM at the expense of the quality of the anchor text

Is this statement consistent with field observations?

Yes and no. Empirical tests indeed show that footer links can transmit PageRank, validating Mueller's position. Sites that removed strategic footer links observed drops in visibility on target pages, confirming that these links were not ignored.

However, there is an important nuance: Google can identify repetitive link patterns across the site and adjust their weighting. A link present on every page in the footer probably does not have the same impact as a unique contextual link. The position itself may not be the discriminating factor, but the recurrence and dilution that result from it might be. [To be verified]: Mueller does not specify whether a global footer link is devalued compared to a footer link that appears on a single page.

What limits should be placed on this assertion?

Google's algorithm integrates hundreds of signals. Saying the position “doesn’t matter” does not mean it is completely ignored in other contexts. For example, Core Web Vitals measure the Largest Contentful Paint, which often concerns primary content. A link in that area can indirectly benefit from strengthened relevance context.

Furthermore, the position influences the click-through rate, which can in turn affect organic CTR and behavioral signals. A footer link generates fewer clicks, thus fewer sessions on the target page, which can indirectly impact its perceived authority. Mueller speaks here of the raw calculation of PageRank, not of all ranking factors.

What to make of the statement about image links and alt text?

This is an essential reminder, but not a novelty. The fact that the alt attribute serves as anchor text for image links has been documented for years. What’s interesting is that Mueller mentions it in the same breath as link positioning, suggesting that many sites still neglect this basic aspect.

In practice, an image link without alt is a link whose semantics for destination Google cannot interpret. It’s like a textual link with the anchor “click here.” It works from a technical standpoint, but contributes nothing to optimized internal linking. The alt thus becomes a critical optimization lever, especially on e-commerce sites where most product links are images.

Should you reconsider your internal link placement strategy?

Not radically, but this statement allows for greater flexibility in internal linking architecture. If you need to strengthen a strategic page, a global footer link can be an acceptable solution without theoretical positional penalties.

However, always prioritize contextual links in the main content when possible. Why? Because they generate more clicks, enhance user experience, and benefit from rich semantic context (surrounding text, co-occurrences). The position may not have a direct effect on PageRank, but it does affect engagement and conversion.

How to optimize image links in this context?

The absolute priority: audit all image links on your site and check for the presence of a descriptive and relevant alt attribute. On an e-commerce site with thousands of products, it’s a significant task, but the ROI is direct in terms of internal linking.

Then, use the alt as true anchor text. If you link an image to a category page “Women’s Running Shoes,” the alt should ideally contain that phrase or a close variant. Don’t settle for “product image” or the default filename. Google reads this attribute as it would read the text of a standard link.

What mistakes should be avoided in implementation?

Do not remove all your footer links just because they might be less effective. If they have been present for a long time and indexed, their removal can create orphan pages or break established PageRank flows. Analyze the impact first with a before/after crawl.

Another pitfall: do not massively duplicate identical links in the header, content, and footer of every page. Google generally only counts the first occurrence of a link to a given URL on a page. Multiplying instances offers nothing and can even dilute the engine's attention.

• Audit for missing or empty alt attributes on all image links on the site
• Write descriptive and optimized alt text for each strategic image link
• Ensure that important footer links do not create unnecessary duplication with the main content
• Prioritize contextual links in the body of the page to maximize user engagement
• Test the impact of adding or removing footer links on pilot pages before global deployment
• Avoid keyword stuffing in alt text: remain natural and descriptive
