Official statement

For a link to exist in our systems, we always need a source and a destination, and both sides must be canonical URLs that are indexed. If we don't have any source in our systems, the link disappears because we don't know what to do with it.

TL;DR

Google only counts a link if both the source AND destination are canonical URLs that are indexed. If either one is missing from the index, the link is simply ignored — it disappears from Google's systems. In practice: a backlink from a deindexed page has zero value, and pointing to a blocked or non-indexed page transfers nothing.

What you need to understand

What does "indexed canonical URL" really mean?

Google only works with canonical URLs — the reference version of a page that Google has decided to display in its search results. If you have multiple variants of the same page (HTTP/HTTPS, www/non-www, URL parameters), Google picks one as canonical.

Indexation is the fact that Google has actually stored this URL in its database and considers it eligible to appear in search results. Without indexation, there is no consideration — neither for content nor for links.

What exactly happens to a link where one end is missing?

Mueller is categorical: the link disappears. Google doesn't know what to do with it, so it completely ignores it. No PageRank transfer, no authority signal, no thematic signal. The link is as useful as a nofollow link multiplied by zero.

Let's be honest — we already knew that a backlink from a deindexed page had no weight. What Mueller confirms here is that this is also true for the destination: pointing to a non-indexed page creates no SEO benefit, even if the source is powerful.

Why does Google work this way?

The search engine works with a link graph between indexed URLs. Each link is an edge between two nodes in this graph. If a node doesn't exist (non-indexed page), the edge cannot exist either — it leads nowhere or comes from nowhere.

This is a fundamental architectural constraint: Google cannot assign value to a link without knowing both endpoints. It does not store "pending links" in hopes that a page will be indexed later.

  • A link only exists in Google's systems if both source AND destination are indexed
  • The URL must be the canonical version recognized by Google, not a variant
  • A backlink from a deindexed page = zero SEO value
  • An internal link to a blocked page (robots.txt, noindex) = useless for PageRank
  • Google does not "set aside" links waiting for indexation — they disappear

SEO Expert opinion

Is this rule consistent with what we observe in the field?

Completely. Tests conducted by the SEO community have confirmed for years that a backlink from a deindexed page brings strictly nothing. We see this regularly with sites that get links from directories or aggregators whose pages are never indexed — zero impact.

What's interesting is that Mueller also emphasizes the destination. Some practitioners still think that an internal link to a noindex page "still counts" for site structure. No. If the target page is not indexed, the link transfers nothing and structures nothing in Google's systems.

What are the gray areas in this statement?

Mueller talks about "indexed canonical URLs," but doesn't specify how long a page must remain indexed for its outgoing links to count. If a page is indexed and then quickly deindexed, does it retroactively lose the value of its outgoing links? [To be verified] — no official data on this.

Another point: what about pages in crawl but not in indexation ("Discovered - currently not indexed" status)? Technically, they're not indexed, so links shouldn't count. But if Google crawls them regularly and stores a record of their links while awaiting future indexation? Mueller says no, but on-the-ground observations suggest that some signals can be "pre-calculated" — it's fuzzy.

In what cases does this rule cause problems?

The classic scenario: you have a new site with little authority. Google indexes your pages slowly. For weeks, some are in "Discovered - currently not indexed." During this period, all internal links pointing to these pages are useless — they transmit nothing.

Result: your internal linking doesn't work at full capacity, which further slows down the indexation of pages waiting. This is a vicious circle that many e-commerce or editorial sites suffer without realizing it.

Warning: If you see a high rate of "Discovered - currently not indexed" pages, your internal links to these pages serve no purpose until they are indexed. Focus your internal linking on already-indexed pages to speed up the process.

Practical impact and recommendations

How can you verify that your links really count?

First, make sure all your strategic pages are indexed. Use Search Console: "Coverage" or "Pages" section. Any page in "Discovered, currently not indexed" or "Excluded" is useless for internal linking and benefits from no backlink.

Next, check your backlink sources. A link from a site whose pages are never indexed will bring you nothing — even if the domain seems powerful. Cross-reference your backlinks (Ahrefs, Majestic) with the actual indexation status of source pages via a "site:URL" search on Google.

What mistakes must you avoid at all costs?

Don't waste your crawl budget on pages you don't want to index. If you block a section in noindex or robots.txt, avoid heavily linking it from your indexed pages — those links are lost.

Another trap: poorly configured canonicals. If Google chooses a canonical URL different from the one you're targeting, all your internal links pointing to your preferred version are ignored — Google mentally redirects them to the canonical, but it doesn't always work as intended.

What should you concretely do to maximize the value of your links?

  • Audit the indexation status of all your pages in Search Console — eliminate "Discovered, currently not indexed"
  • Focus your internal linking on pages actually indexed
  • Verify that your backlinks come from indexed pages (test "site:URL" on Google)
  • Fix canonicals so Google properly recognizes your target URLs
  • Avoid heavily pointing to noindex or blocked pages — it serves no purpose
  • Relaunch indexation of strategic blocked pages via "Request indexation" in Search Console
The rule is simple: a link only exists if source AND destination are indexed. Everything else is invisible to Google. Concentrate your internal linking and netlinking efforts on URLs actually present in the index. If you notice a high rate of non-indexed pages or inconsistent canonicals, this is a priority project. These indexation and structure issues can be tricky to diagnose and resolve alone — especially on large sites. Calling on a specialized SEO agency often allows you to quickly identify bottlenecks and implement an effective indexation strategy so that every link truly counts.

❓ Frequently Asked Questions

Un lien depuis une page en noindex compte-t-il ?
Non. Si la page source n'est pas indexée (noindex, robots.txt), le lien disparaît des systèmes Google et ne transmet rien — ni PageRank, ni signal thématique.
Que se passe-t-il si la page cible est indexée puis désindexée ?
Les liens pointant vers cette page cessent de compter dès qu'elle sort de l'index. Google ne conserve pas de trace de ces liens dans ses systèmes.
Un lien interne vers une page « Discovered - currently not indexed » sert-il à quelque chose ?
Non, tant que la page n'est pas indexée. Le lien n'existe pas dans les systèmes Google, donc il ne transmet aucun PageRank ni signal.
Comment savoir si mes backlinks proviennent de pages indexées ?
Testez chaque URL source avec une recherche « site:URL » sur Google. Si la page n'apparaît pas, le lien ne compte probablement pas.
Une canonical mal configurée peut-elle faire perdre des liens ?
Oui. Si Google choisit une URL canonique différente de celle que vous ciblez, les liens pointant vers votre version préférée peuvent être ignorés ou redirigés de manière imprévisible.
