Should you really apply 'nofollow' to pages that lack SEO interest?

Why does Google differentiate between login pages and legal notices?

Google makes a clear distinction between two categories of pages. On one side are login pages, shopping carts, or administrative interfaces that should never show up in search results. On the other side are informative pages like legal notices or privacy policies that, while not very appealing from an SEO perspective, fulfill a real user need.

This distinction is based on a simple logic: some pages actively harm user experience if indexed, while others are simply neutral. A user who stumbles upon a login page through Google won’t find anything useful. In contrast, someone specifically searching for "privacy policy [site name]" should be able to access that information.

Is 'nofollow' really enough to block indexing?

Let’s be honest: nofollow does not block indexing. It merely tells search engines not to follow the links on the page or to the relevant page. To truly prevent indexing, you need to combine several signals: noindex in the meta robots, X-Robots-Tag HTTP, and ideally an exclusion via robots.txt if you also want to save crawl budget.

Google intentionally simplifies its message here. In practice, a single nofollow doesn’t guarantee anything. I’ve seen nofollow pages indexed because they received external backlinks or users shared them on social media. Context matters more than the attribute in isolation.

Why does Google emphasize content creation over these technical details?

This recommendation reflects a clear stance from Google: stop over-optimizing the details and focus on what really generates value. SEOs sometimes spend hours debating whether a page should be nofollow, while that time would be better invested in producing content that naturally attracts links.

This also sends a message to sites that misuse nofollow to artificially sculpt PageRank. This practice has lost its effectiveness since Google changed the status of nofollow from "directive" to "hint" in 2019. Today, Google can choose to ignore your nofollow if it believes the link adds contextual value.

• Nofollow is suitable for pages to be completely excluded (login, admin, cart)
• Legal informational pages: no need for nofollow, they can serve users
• Nofollow alone does not block indexing: combine with noindex for more security
• Google considers nofollow as a hint, not an absolute directive since 2019
• Priority: create linkable content rather than micromanaging every link attribute

Is this recommendation consistent with real-world observations?

Partially. Across thousands of audits, I find that Google regularly indexes technical pages despite the presence of nofollow, especially if they receive external signals (shares, direct backlinks). Google’s statement works in an ideal world where sites are perfectly structured and crawl budget is never an issue.

In reality, e-commerce sites with thousands of product variations, user-generated content platforms, or complex multilingual sites must absolutely manage their indexing surgically. Letting Google "figure it out" often leads to massive waste of crawl budget on low-value URLs.

What specific cases contradict this minimalist approach?

The e-commerce navigation facets serve as the most glaring example. A site with color, size, and price filters can generate thousands of almost duplicate URLs. Google says, "focus on quality content," but realistically, if you don’t manage those pages with noindex + canonical, you dilute your equity and disrupt the ranking algorithm. [To be verified] that this passive approach works on sites with over 10,000 pages.

Another case: internal search pages or user filter results. I’ve seen sites lose 40% of their organic visibility because Google was massively indexing empty or irrelevant result pages. The advice "don’t worry about nofollow" becomes dangerous in this context.

What is the true nuance that Google intentionally omits?

Google simplifies its message to avoid historical abuses of PageRank sculpting, but this simplification can harm sophisticated sites. The real recommendation should be: "Do not use nofollow to manipulate the flow of PageRank, but absolutely use noindex + canonical + robots.txt to control the indexing of technical pages."

What’s missing here: no mention of crawl budget, no nuance regarding large sites, and no distinction between SMEs with 50 pages and marketplaces with 5 million URLs. An SEO expert knows that the size and complexity of the site radically change the indexing strategy.

What specific actions should you take on your technical pages?

Start with a complete indexing audit via Search Console and a crawler like Screaming Frog. Identify which pages are currently indexed that shouldn’t be. Classify them into three categories: pages to be completely excluded (noindex + robots.txt), pages to keep indexed but without passing equity (noindex or canonical), and legitimate pages that deserve to be indexed.

For login, cart, checkout pages: noindex in the meta robots is the minimum. Add a robots.txt exclusion if you really want to save crawl budget. For legal notices and privacy policies, let them be indexable without overthinking, unless you notice they are draining crawl budget at the expense of important pages.

How can you prioritize your efforts without falling into over-optimization?

Apply the inverted 80/20 rule: don’t spend 80% of your time on the 20% of technical pages that don’t impact your rankings. Focus on content that drives traffic and conversions. Monthly check in Search Console to ensure Google is not massively indexing unwanted pages, but don’t micromanage every link attribute.

Create a validation process for any new section of the site: before launch, define the indexing strategy (indexable or not, canonical, nofollow or not). Document these choices in a shared file with the dev and product teams to avoid regressions during updates.

What critical mistakes should you absolutely avoid?

Do not confuse nofollow and noindex. I’ve audited dozens of sites where technical teams blocked indexing with nofollow alone, thinking it was sufficient. The result: sensitive pages indexed and visible on Google. If you want to block indexing, use noindex, not nofollow.

Another trap: blocking via robots.txt AND noindex simultaneously. If you prohibit crawling in robots.txt, Google cannot read the noindex in the HTML of the page, so it might still index it (without content) if it receives backlinks. Use one or the other depending on the context, rarely both together.

• Search Console audit: identify unwanted indexed pages
• Login/admin pages: noindex + robots.txt exclusion if crawl budget is limited
• Legal notices/terms: keep them indexable unless there’s a proven problem
• Nofollow only for links to unvalidated external content (UGC, comments)
• Document your indexing strategy by page type
• Quarterly review of indexed URLs vs. planned strategy
