Is nofollow applied link by link or page by page?

What is the importance of clarifying the scope of nofollow application?

For years, many SEOs mistakenly believed that placing a single nofollow link on a page could impact the PageRank transmission of all other links present. This misconception arose from confusion between how nofollow is treated at the link level and the mechanics of PageRank distribution at the page level.

Google clarifies: the nofollow attribute applies only to the specific link it is attached to. The other links on the page continue to operate normally. If you have 10 links on a page and only one has nofollow, the other 9 transmit juice as usual.

How does PageRank distribution work when some links are nofollow?

Historically, Google divided the available PageRank by the total number of outgoing links on the page, including nofollow. As a result, a nofollow link consumed a portion of PageRank without passing it on — that portion was lost.

Since the change of nofollow to a hint rather than a directive, Google can choose to follow or not follow a link marked as nofollow. The exact mechanics of distribution remain unclear, but the official statement confirms that applying a nofollow to a link does not prevent the other links on the page from playing their role.

What are the implications for internal linking and backlinks?

For internal linking, this rule is critical: if you place a nofollow on a link to your privacy policy or terms and conditions, the other internal links on the page — the ones pointing to your strategic content — are not affected.

For external backlinks, the same logic applies: a nofollow link in a comment or widget does not impact the normal editorial links present on the same page. Each link is treated independently.

• The nofollow attribute applies only to the individual link, not to the entire page.
• The other links on the page continue to pass PageRank normally.
• Nofollow is now treated as a hint; Google can decide whether or not to follow the link.
• Mixing nofollow and dofollow on the same page does not dilute the juice of valid links.

Is this statement consistent with real-world observations?

Yes, it confirms what empirical tests have shown for years. When tracking ranking changes after adding or removing nofollow on specific links, only those links see their impact change. The other links on the page remain stable in their ability to transmit juice.

However, Google remains deliberately vague about the PageRank distribution mechanics when nofollow links are present. Is the PageRank not transmitted by the nofollow links redistributed to the dofollow links, or is it simply lost? Google does not state this explicitly. [To be verified]

What nuances should be considered regarding this rule?

Be careful: the fact that nofollow applies link by link does not mean you should overuse nofollow on your pages. A page filled with nofollow links sends a strange signal to Google — why so many non-editorial links? This could affect the overall perceived quality of the page, even if technically each link remains independent.

Another nuance: the nofollow has been a hint for several years, not a strict directive. Google can choose to follow a nofollow link if it deems it relevant for indexing or crawling. This flexibility changes the game: a nofollow link is no longer a guarantee that it won't be followed.

In which cases does this rule not apply directly?

If you use the nofollow at the meta robots tag level (<meta name="robots" content="nofollow">), then the whole page no longer transmits PageRank through any link. That's a global directive, not at the link level.

Similarly, the UGC and sponsored attributes introduced alongside nofollow operate on the same logic: they apply link by link. But combining multiple attributes on the same link can lead to unexpected behaviors — Google considers the most restrictive, or interprets the combination as a contextual signal.

What concrete actions should you take on your existing pages?

Audit your strategic pages to identify links with unnecessary nofollow. Typically, this includes internal links to important categories, key product pages, or pillar content. If these links are marked as nofollow without editorial justification (login, terms, etc.), remove the attribute.

Conversely, ensure that links to low SEO value pages (login, cart, internal search) correctly carry a nofollow or UGC/sponsored attribute depending on the context. This concentrates PageRank on the links that truly matter.

What mistakes should be avoided when using nofollow?

Do not apply nofollow to strategic internal links reflexively or out of fear of “diluting” PageRank. This fear comes from a misunderstanding: the nofollow on an internal link makes you lose an opportunity to pass juice to an important page.

Avoid also applying nofollow to all external links by default. Outgoing editorial links to quality sources enhance the credibility of your content in Google's eyes. Reserve nofollow for sponsored links, UGC links, or links to dubious sites.

How can you ensure that your site is using nofollow correctly?

Use a crawler like Screaming Frog or Oncrawl to extract all links from your site and identify those marked nofollow, UGC, or sponsored. Filter by link type (internal vs. external) and by source page. This gives you a quick overview.

Examine pages with high internal PageRank (typically the home page, top categories): these pages should pass juice to your priority content. If they point to administrative pages in dofollow or to strategic content in nofollow, correct this.

• Remove nofollow from internal links to strategic pages.
• Add nofollow to links to utility pages (login, terms, etc.).
• Audit external links: do not apply nofollow by default to quality editorial links.
• Check consistency between nofollow, UGC, and sponsored attributes according to context.
• Crawl the site to map all link attributes and detect inconsistencies.
