Should we expect a shake-up of nofollow links in Google’s algorithm?

Why is Google testing new uses for nofollow now?

The nofollow has existed since 2005 and underwent a major evolution in 2019 when Google transformed it from a strict directive to a simple signal (hint). Since then, SEOs have observed that Google can choose to ignore nofollow in certain contexts, particularly for indexing or crawling.

Gary Illyes mentioning three simultaneous sub-projects means that Google is exploring several parallel avenues — likely to refine the weighting of these links in the algorithm, improve spam detection, or better manage UGC and sponsored contexts. The fact that a ranking official requested a public communication indicates that the impact could directly affect rankings.

Which aspects of nofollow are likely to be involved in these tests?

The three nofollow attributes (generic nofollow, ugc, sponsored) already offer theoretical granularity, but their real impact remains unclear. Google may be testing a better differentiation between these attributes, a more selective treatment based on the page context, or a new way to distribute PageRank through these links.

The areas most likely to be affected: internal PageRank sculpting (particularly through menus and footers), the management of outgoing links to partners, and the impact of UGC links in forums or comments. If Google decides to treat nofollow differently based on content type or site reliability, current strategies could lose effectiveness.

Does this announcement really promise transparent communication from Google?

The mention of a mandatory public announcement is unusual and worth highlighting. Typically, Google rolls out algorithmic changes without warning — except for major updates like Core Updates or new standards (such as Core Web Vitals).

That a ranking official demands communication suggests either an impact significant enough to justify transparency or a desire to test the SEO ecosystem's reaction before a large-scale rollout. It remains to be seen if this announcement will be as detailed as promised — Google's historical record regarding clarity is mixed.

• Nofollow shifted from directive to signal in 2019, giving Google more interpretative freedom.
• Three parallel projects indicate a multi-faceted exploration, likely focusing on ranking, crawling, and indexing.
• A formal public announcement will be made if any of the projects are deployed — which is rare for this type of change.
• UGC and sponsored contexts may be treated differently in the future.
• The impact could affect PageRank sculpting and internal linking strategies.

Does this statement align with field observations?

Since 2019, SEOs have observed that Google does not consistently respect nofollow attributes — some nofollow-labeled links appear in crawl data, while others visibly pass authority. Tests of PageRank sculpting via nofollow yield inconsistent results from site to site, reinforcing the idea that Google employs undocumented contextual logic.

That three projects are being tested simultaneously confirms this ambiguity: Google is likely seeking to formalize rules it already applies empirically. But the devil is in the details — without visibility into the exact criteria (site type, link volume, dofollow/nofollow ratio, semantic context), it’s impossible to predict the actual impact. [To verify]: whether these tests apply solely to large sites or also to smaller structures.

What risks should we anticipate if Google changes nofollow rules?

The main danger: losing control over the distribution of internal PageRank. Many sites use nofollow to limit flow to login pages, facet filters, or user-generated content. If Google decides to treat these links differently based on their context, pages deemed non-priority could gain more weight — and conversely, strategic pages could lose it.

Another risk: a tightening of penalties on poorly declared sponsored links. If the tests lead to better automatic detection of unreported paid links, some sites may face de-ranking without having changed their practices. PBN networks and aggressive guest-posting strategies are the most exposed.

Should we change our practices now or wait for the official announcement?

Let’s be honest: without concrete details, adjusting your strategy now is speculative. SEOs who have over-optimized PageRank sculpting via nofollow should begin auditing their internal links — not to redo everything, but to identify critical dependency areas on this technique.

Specifically: if your internal linking heavily relies on nofollow to control flow (navigation, footers, sidebar), prepare a plan B. Ideally, design a natural architecture where important pages receive contextual dofollow links without artificially neutralizing the rest. Waiting for the official announcement is legitimate, but having a diagnosis ready allows you to react quickly if the change negatively impacts your rankings.

What should be audited first on your site before a potential change?

First step: map all internal and external nofollow links. Use Screaming Frog or an equivalent crawler to extract the complete list and segment by type (navigation, footer, editorial content, UGC, sponsored outbound links). The goal: to understand where you use nofollow and why.

Next, identify the pages that depend exclusively on nofollow links to limit their PageRank. If a strategic page only receives weak contextual dofollow links and everything else is neutralized by nofollow, it risks losing weight if Google changes the rules. Conversely: identify pages you don’t want to rank that might receive more authority if Google treats nofollow differently in context.

What mistakes should be avoided in current nofollow management?

Do not confuse nofollow and noindex — a still common mistake. Nofollow does not block crawling or indexing; it merely (in theory) cuts off the PageRank transmission. If you really want to prevent Google from indexing a page, use the noindex meta tag or the X-Robots-Tag.

Another pitfall: overusing nofollow on editorial internal links for fear of diluting PageRank. This practice is counterproductive — Google values sites that create coherent navigation paths. If a page deserves to be linked in content, it deserves a dofollow link. Reserve nofollow for legitimate cases: non-editorial outbound links, UGC, sponsored or affiliate links.

How can internal linking strategy be adapted if rules change?

Favor a semantic silo architecture where each thematic cluster is connected by natural contextual links. This model withstands algorithmic changes better than artificial PageRank sculpting via nofollow. Dofollow links should point to pages with high ranking potential, while secondary pages are supported by a coherent but less dense linking strategy.

If Google rolls out one of the tested projects, the ability to quickly reorganize your linking will be crucial. Document your current choices (why a page is nofollow, what purpose it serves) to pivot if necessary. And test the impact of gradual changes: moving some strategic links from nofollow to dofollow and measuring the positional changes can provide clues even before the official announcement.

• Extract all internal and external nofollow links via a complete site crawler.
• Identify critical pages that depend on PageRank sculpting via nofollow.
• Check that the ugc and sponsored attributes are correctly applied to user-generated content and partnerships.
• Document the reasons for each use of nofollow to facilitate quick adjustments if necessary.
• Test the gradual shift of strategic links to dofollow to anticipate the impact.
• Prefer a semantic silo architecture over excessive optimization via nofollow.
