Does using nofollow on internal links really enhance SEO?

Why does this statement undermine PageRank Sculpting?

The manipulation of internal links with nofollow dates back to when the attribute was still a strict directive. SEOs used to try to concentrate the flow of PageRank to strategic pages by blocking its spread to pages deemed secondary (legal mentions, terms and conditions, login pages).

Since Google transformed nofollow into a simple hint rather than a directive, this technique has lost its effectiveness. The engine now decides on its own whether to follow these links, making any control attempt unrealistic. Mueller confirms what field tests suggested: manipulating internal PageRank flow no longer works.

What exactly does a normal internal link structure mean?

Google encourages a natural and logical architecture, where links reflect the actual content hierarchy. This means linking pages according to their thematic relevance and business importance, without technical gimmicks.

A healthy structure prioritizes reduced click depths for important pages, a coherent semantic network, and descriptive anchors. PageRank distributes naturally according to the site's topology, without needing risky manual interventions.

Does this statement apply to all types of internal links?

Mueller primarily targets attempts at strategic manipulation of PageRank. He does not challenge the legitimate use of nofollow on certain functional links, such as sorting filters, alternative paginations, or user-generated links.

The nuance is important: Google distinguishes defensive use of nofollow (to avoid crawling areas of no value) from its offensive use (artificially sculpting PageRank). The former remains acceptable in certain specific contexts, while the latter is clearly disapproved.

• Internal nofollow no longer boosts the ranking of targeted pages since it became a hint
• A coherent link architecture is better than any technical manipulation
• Google favors natural structures that reflect the actual content hierarchy
• Defensive use of nofollow remains acceptable on functionally valueless SEO areas
• Internal PageRank now distributes according to the natural topology of the site

Is this position consistent with field observations?

Tests conducted by the SEO community largely confirm this statement. Since nofollow transitioned to hint mode, no measurable benefits have been observed from attempts at internal PageRank Sculpting. Sites that have cleaned up their internal nofollows have seen neither significant gains nor losses.

What truly works are architectural adjustments: reducing click depth for strategic pages, consolidating thematic linking, and removing zombie pages. These structural optimizations yield measurable results where internal nofollow fails.

What edge cases does Mueller not address?

The statement remains vague on some specific scenarios. E-commerce sites with thousands of filter facets may legitimately want to control their crawl surface. Nofollow or robots.txt can then be used to preserve the crawl budget rather than manipulate PageRank. [To be verified] if Google considers this use acceptable or recommends other approaches.

Similarly, platforms with user-generated content (forums, comments) use nofollow by default for security reasons. Mueller does not clarify if this practice remains relevant, although logic suggests it does to prevent spam.

Should you remove all existing internal nofollows?

Not necessarily. If internal nofollows exist for good functional reasons (saved crawl, user areas, dynamic filters), removing them could create more problems than they solve.

However, if these attributes were placed with a view to PageRank Sculpting (typically in footers, sidebars, legal pages), their removal will simplify the architecture without risk. The real task is to audit the initial reason for each nofollow and decide on a case-by-case basis, not to apply a mechanical rule.

What should you do if your site heavily uses internal nofollow?

Start with a comprehensive audit of your internal links to identify those marked as nofollow and understand their initial justification. A crawl with Screaming Frog or OnCrawl will quickly reveal usage patterns.

Then, categorize these links into two groups: those used for PageRank Sculpting (to be removed) and those with a legitimate technical justification (to be retained or handled differently). This distinction is essential to avoid unexpected side effects.

How can you effectively restructure your internal linking?

Favor a thematic silo approach where pages within the same category naturally link to each other. Ensure that your strategic pages are accessible in 2-3 clicks maximum from the homepage.

Work on your link anchors to make them descriptive and semantically rich, without falling into over-optimization. The link structure should primarily serve the user: if a link makes sense for navigation, it will make sense for Google.

What critical mistakes should you avoid during the redesign?

Never remove all your internal nofollows at once without prior analysis. Some may hide deeper structural issues (duplication, poorly managed pagination, infinite facets). Removing the attribute without addressing the underlying issue will worsen the situation.

Avoid also falling into the opposite excess: adding internal links everywhere artificially. A forced over-linking dilutes the signal and creates a degraded user experience. Relevance always prevails over quantity.

• Crawl the site to identify all links marked as internal nofollow
• Document the reason for each use (sculpting vs. technical)
• Remove nofollow associated with attempts to manipulate PageRank
• Retain or handle otherwise legitimate technical uses (robots.txt, pagination)
• Restructure linking into coherent thematic silos
• Ensure strategic pages are accessible in 3 clicks maximum
• Regularly audit the distribution of internal PageRank with specialized tools
