Nofollow Internal Links: Why It Hurts More Than It Helps

Adding rel="nofollow" to internal links sounds like a clever way to control where your PageRank flows. In practice, it has the opposite effect: it destroys PageRank rather than redirecting it, leaves important pages starved of link equity, and disrupts the site structure signals Google uses to understand your content. This guide explains why nofollow internal links are almost always a mistake, what to do instead, and when — in rare cases — they might be acceptable.

What Is PageRank Sculpting?

PageRank sculpting is a technique from early SEO history in which practitioners used rel="nofollow" on internal links to intentionally control which pages received link equity. The theory was straightforward: a page with ten outbound links distributes its PageRank evenly among all ten destinations. If you nofollow five of those links — say, the links to a privacy policy, a login page, and other low-value pages — you concentrate more equity on the remaining five "important" links.

The goal was to funnel ranking power toward revenue-generating pages: product pages, landing pages, money-keyword articles. The privacy policy does not need to rank, so why give it PageRank? By nofollowing the link to it, you could theoretically push more juice to your category pages. This logic drove significant experimentation in the 2007–2009 era of SEO, and many practitioners believed they were seeing positive results.

The technique was always fragile — it required precise assumptions about how Google divided PageRank, and small changes to site architecture could undermine the entire sculpting strategy. But the fatal blow came from Google itself, which clarified exactly how nofollow interacts with PageRank in a way that made sculpting not just ineffective but actively harmful.

Why It Seemed to Work Before 2009

The apparent success of PageRank sculpting before 2009 rested on a misunderstanding of how Google was handling nofollowed links at the time. In the original nofollow implementation, Google did not follow nofollowed links and also did not distribute the PageRank that would have gone through them. This meant that if a page had ten links and five were nofollowed, only five links were counted in the PageRank calculation — and the PageRank was divided among those five.

Under that model, nofollowing low-value links genuinely did concentrate more equity on the remaining followed links. A page with a PageRank of 10 and five followed links passed 2 units to each. Nofollow the other five, and those same five followed links still received 2 units each — but now they were competing with fewer links. Whether this actually produced ranking improvements in practice was debated, but the theoretical basis was defensible.

This is also why so much early SEO content recommended nofollowing boilerplate links: footer links, breadcrumbs, navigation duplicates, pagination links. The SEO community built entire strategies around the assumption that nofollow was a redirectable valve rather than a drain. That assumption was wrong, and Google corrected the record.

How Google Changed Nofollow Behavior in 2009

In June 2009, Google's Matt Cutts published a blog post titled "PageRank Sculpting" that definitively ended the debate. Cutts explained that Google had changed how it handled nofollowed links: the PageRank that would have passed through a nofollowed link now simply evaporated — it was not redistributed to the followed links on the same page. Nofollow had become a leak, not a valve.

Under the new model, a page with ten links — five followed, five nofollowed — divided its total PageRank by ten, passed two units through each of the five followed links, and discarded the remaining two units for each nofollowed link. The followed links received no extra equity from the nofollowed ones. Sculpting had been neutralized: you were not concentrating PageRank, you were destroying it.

This change retroactively made all existing PageRank sculpting implementations counterproductive. Every site that had been nofollowing internal links to "concentrate" equity was actually hemorrhaging it. The correct response was to remove nofollow from all internal links and let PageRank flow naturally. Many sites that did this saw ranking improvements as previously starved pages received the equity they had been owed.

The 2019 Nofollow Update: Treated as a Hint

In September 2019, Google announced another significant change to how it treats the nofollow attribute, along with two new link attributes: rel="sponsored" for paid and affiliate links, and rel="ugc" for user-generated content links. Critically, Google announced that all three attributes — including nofollow — would henceforth be treated as hints rather than directives.

What "hint" means in practice: Google may choose to follow a nofollowed link for crawling and indexing purposes, but still discard it for PageRank and anchor text purposes. Alternatively, Google may choose to ignore the nofollow hint entirely if it has other signals suggesting the link should count. The key word is "may" — Google reserves the right to interpret these attributes as it sees fit, rather than treating them as commands it must obey.

For internal link sculpting specifically, this makes nofollow even less reliable as a tool. Even if you wanted to use nofollow to prevent PageRank from passing through a link, Google might simply choose to honor the link anyway. The 2019 update made nofollow a weaker signal for external links (where it is sometimes legitimately used) and made it essentially meaningless as an internal link management strategy.

Why You Should NOT Nofollow Internal Links

The case against nofollowing internal links is straightforward once you understand the 2009 behavior change. Every nofollow on an internal link destroys a portion of your site's PageRank rather than redirecting it. If your homepage links to ten pages and three of those links are nofollowed, you are leaking 30% of your homepage's outbound PageRank. Since the homepage is typically your site's highest-authority page, that loss is significant.

Beyond PageRank, nofollow on internal links disrupts the structural signals Google uses to understand your site. Internal linking patterns tell Google which pages you consider most important, how topics relate to each other, and what the information architecture of your site looks like. When you nofollow internal links, you are sending mixed signals: "this page exists, but I do not want to vouch for it" — an incoherent message for your own content.

There is also a crawl budget consideration. While Google may still crawl nofollowed links (especially since 2019), the inconsistency creates uncertainty. For large sites where crawl budget is a genuine constraint, you want every internal link to be a clear, unambiguous signal: follow this, it matters. Nofollow adds noise to that signal without providing any compensating benefit.

What Happens When You Nofollow Internal Links Today

In the current Google model, when Googlebot encounters a nofollowed internal link, it treats the attribute as a hint. In most cases, it will still crawl the linked URL — so you gain no crawl budget savings from nofollowing internal links. What you do lose is the PageRank that would have passed through that link, and the anchor text signal that would have contributed to the destination page's relevance for its target keywords.

The net effect is a weaker internal link graph. Pages that would have been well-supported by your strongest content are instead receiving diluted or zero equity through nofollowed links. This matters most for pages that rely heavily on internal links because they have limited external backlinks — which is precisely the situation for most deep pages on content-heavy sites.

A site crawl tool that analyzes link equity flow will often reveal this problem visually: pages that should have strong internal link equity based on their position in the site show up with surprisingly low scores, and tracing the inbound links reveals a nofollow somewhere upstream. Fixing a single nofollowed navigation link can unlock equity flow to hundreds or thousands of pages.

The Right Way to Manage Internal PageRank Flow

The correct approach to managing where PageRank flows within your site is through architecture, not attributes. Site structure determines which pages are close to the root (homepage), how many internal links they receive, and what anchor text those links carry. Pages you want to rank strongly should be well-connected: linked from the homepage, from relevant category pages, and from closely related content articles. Pages that serve utility purposes (privacy policy, login, terms of service) naturally receive fewer links and that is fine — you do not need to artificially suppress their equity.

Pillar page architectures are the modern best practice for managing equity flow in content-heavy sites. A pillar page covering a broad topic links to cluster pages covering subtopics, and those cluster pages link back to the pillar. This creates a hub-and-spoke structure where equity flows efficiently between related pages, reinforces topical authority, and makes the site's information architecture legible to Google. No nofollow required — the architecture does the work.

Link depth — how many clicks a page is from the homepage — is a more powerful lever than nofollow. A page at click depth 2 receives far more PageRank than a page at click depth 5, simply because more equity flows to shallower pages before it disperses. If you want a page to rank, reduce its click depth by adding links to it from high-authority shallow pages. This is the equivalent of PageRank sculpting, done correctly.

When Nofollow on Internal Links Might Be Acceptable

There are a handful of genuine edge cases where nofollow on an internal link is defensible. The clearest case is links to pages that are already blocked by noindex or robots.txt — login pages, user dashboard pages, admin panels, internal search results. For these pages, you do not want them indexed regardless, and while blocking them via robots.txt or noindex is the primary mechanism, some teams add nofollow as a belt-and-suspenders measure. This does not help, but it does not hurt much either given the pages are already excluded.

Another edge case is links within user-generated content sections of your own site — for example, a community forum where users can post links to other pages on your domain. If you cannot fully control the destination content, treating those self-referential links with ugc or nofollow is a defensible precaution, though it is unusual for truly internal destinations.

In virtually every other case — navigation links, content links, sidebar links, footer links, breadcrumb links — nofollow on internal links provides no benefit and actively destroys PageRank. When in doubt, remove the nofollow attribute and let the link pass equity naturally.

How to Audit Your Site for Unnecessary Nofollow Internal Links

A dedicated site crawl is the only reliable way to find nofollow internal links — they are invisible to users and easy to miss in code reviews. Screaming Frog SEO Spider crawls all internal links and flags those carrying the nofollow attribute. Run a crawl, navigate to the Internal Links tab, and filter by the Follow column to isolate nofollowed links. Pay particular attention to links in your global navigation (header, footer, sidebar menus) — these appear on every page and have the greatest impact on equity distribution.

Ahrefs Site Audit also detects nofollow internal links and presents them in the Internal Pages report. The advantage of Ahrefs is that it correlates link attributes with URL Rating (UR) — you can see directly which pages are receiving low equity scores and whether nofollowed inbound links are the cause. This makes it easier to prioritize fixes by SEO impact rather than raw link count.

SitemapFixer crawls your sitemap and linked pages, surfaces internal links carrying nofollow, and highlights the pages most affected by blocked equity flow. This is especially useful for identifying systemic issues — if a theme template or plugin is adding nofollow to a class of links, you will see the pattern immediately across hundreds of instances rather than finding them one by one. After fixing, re-crawl to confirm the attribute has been removed throughout the site.

Better Alternatives to PageRank Sculpting

The goal that PageRank sculpting was meant to achieve — concentrating ranking power on important pages — is legitimate. The method was wrong, but the objective is sound. Flat site architecture achieves this goal far more effectively. By keeping your most important pages at most two clicks from the homepage, you ensure they receive ample PageRank from your strongest pages. Pages that do not need to rank do not need to be suppressed — they simply need fewer inbound links from high-authority pages.

Strategic internal linking from your highest-traffic content to your most important commercial pages is another powerful lever. If you have blog posts that attract significant organic traffic, those posts have link equity to pass. Adding contextual internal links from those posts to your money pages — with descriptive anchor text — directly boosts the ranking power of the destination pages. This is PageRank sculpting done correctly: not by blocking equity, but by creating more of it in the right places.

Reducing orphan pages is the third pillar. Orphan pages — pages with no inbound internal links — receive almost no PageRank regardless of how well-structured the rest of your site is. A full internal link audit often reveals dozens or hundreds of orphaned pages, particularly in older sites with frequent content additions. Connecting these pages into your internal link structure can produce significant ranking improvements with no new content required.
