When managing a business website, it is easy to treat noindex and nofollow as interchangeable ways to keep a page out of search results. They do different jobs. Understanding the difference between noindex and nofollow helps you control what search engines can show, how they discover links, and where they spend time crawling—without accidentally hiding useful pages from customers.

What noindex tells search engines

A noindex directive asks a search engine not to include a particular page in its search results. It does not, by itself, prevent the page from being crawled. A search engine generally needs to access the page to read the directive, so blocking that URL in robots.txt can prevent it from seeing a page-level noindex instruction.

Site owners commonly use noindex on pages that are useful to visitors but have little value as search landing pages. Examples may include internal search results, account pages, duplicate campaign pages, or certain stages of a checkout process. The right choice depends on whether the page should be publicly accessible and whether it offers distinct value to a search user.

Noindex can be delivered through a robots meta tag in the page’s HTML or through an X-Robots-Tag HTTP response header. The header can be useful for files such as PDFs, which do not have an HTML head section. After adding a directive, allow crawlers to access the URL and check that the instruction is present in the rendered page or response.

What nofollow does—and does not do

Nofollow concerns links, not whether the page containing them appears in search results. On a link, rel=”nofollow” signals that the publisher does not want to endorse the destination or pass along a ranking signal in the usual way. It can be appropriate for links that are paid, user-generated, or otherwise not editorially vouched for. For paid placements, Google also recognises the more specific rel=”sponsored”; for comments and forums, rel=”ugc” may be a better fit.

A page can be indexed while its links are marked nofollow. Conversely, a page can be noindexed while its links are followed. The two instructions solve separate problems, so applying both should be a deliberate decision rather than a default setting.

It is also unwise to treat nofollow as a guaranteed crawl block. Search engines may treat it as a hint when deciding how to handle a link. If a URL must not be accessible, use appropriate access controls; if it must not appear in search, use a crawlable noindex directive. Neither tool replaces security measures for private information.

Choosing the right directive

  • Use noindex when a page should remain available to visitors but should not be listed in search results.
  • Use nofollow on a link when you do not want to signal endorsement or pass ranking credit in the usual way.
  • Use neither automatically on a valuable service, product, or article page just because it is new, has few links, or is not yet ranking.

Before changing directives, check the page’s purpose, canonical URL, internal links, and current search performance. A noindex tag on a page that attracts qualified leads can quietly remove an important entry point. Likewise, adding nofollow to every internal link may make it harder for crawlers to discover parts of the site, without providing a useful safeguard.

Backlinks, discovery, and indexing

Backlinks can help search engines discover pages, but a link alone does not guarantee that the destination will be indexed. Search engines consider factors such as crawl access, duplicate content, page quality, and internal navigation. If a page is missing from results, check for accidental noindex directives, blocked resources, redirect chains, and weak internal links before assuming that more backlinks are the answer. For a structured troubleshooting process, see this guide to indexing backlinks.

When earning or placing links, distinguish between a site’s own indexing controls and the attributes on links pointing to it. Nofollow on an incoming link does not mean the destination page is noindexed. It simply describes how the linking site labels that relationship. The destination still needs to be crawlable, useful, and eligible for search.

Recheck directives during a redesign

Website changes are a common source of indexing mistakes. A staging site may have been set to noindex, and that setting can accidentally survive the move to production. A redesigned site can also change URLs, navigation, templates, or analytics, so check both search visibility and business outcomes after launch.

For teams planning a rebuild, an end-to-end website redesign checklist can help organise audits, testing, and launch tasks. Include website redesign conversion rate measurement in that work: compare leads, sales, and key page actions before and after launch, while checking that important URLs remain crawlable and indexable. Osdire is one place businesses can find freelancers for web development, design, writing, and marketing tasks, but whichever team does the work, assign someone responsibility for the final SEO checks.

A simple review before publishing

For each important page, confirm that the URL loads without a login, the robots.txt file does not block crawling, and no unintended noindex instruction appears in the HTML or response headers. Then inspect outbound and user-submitted links to decide whether any need nofollow, sponsored, or user-generated attributes. Keep a record of changes so a future redesign or plugin update does not undo them.

The practical rule is straightforward: noindex controls search-result eligibility; nofollow labels a link relationship. Use each for its intended purpose, verify the result after implementation, and avoid relying on either directive to solve a problem it was not designed to address.
