Link stability is one of those SEO ideas that keeps resurfacing, usually attached to a Google patent from 2005 and a warning that changing your links too often will cost you rankings.

Most articles on it reach the same conclusion. The patent mentioned link churn, the wording is gone now, so the idea is dead.

That conclusion rests on a misreading, and the misreading is worth correcting, because the underlying mechanism is still in the granted patent and it has more to do with your internal links than your backlinks.

Two different things share this name

Before anything else, the term is used for two unrelated ideas, and the arguments talk past each other as a result.

The first is outbound link churn. How often the links on your own pages change, including the URLs and the anchor text. This is what the patent discusses, and it is entirely within your control.

The second is backlink longevity. How long a link to your site survives on somebody else’s page. You do not control that one at all.

Almost every article claiming link stability is a myth is answering the second question. The patent is about the first. Keep them separate and the evidence gets much clearer.

What the patent actually says

The 2005 application, published as US20050071741A1, named link churn directly. Its claims described determining an indication of link churn for a linking document and adjusting the ranking of the linked document based on it, with churn computed from the extent to which links change over time.

The 2005 application named link churn explicitly.

The phrase does not appear in the granted version, and that is where most write-ups stop. They treat a missing phrase as a retracted idea.

Read the granted patent and the mechanism is still there. US7346839B2 describes scoring a document based on the manner in which anchor text changes over time. It names the freshness of anchor text as a scoring factor. Claim 32 covers scoring a page on whether its content has drifted so that it no longer matches the anchor text pointing at it.

A later Google patent, US8244722B1, models how changes in link-based information move a document’s rank over time, partly to catch rank-modifying spam.

So the label was dropped. The idea that link and anchor changes carry information was not.

What this means in practice

None of that makes link stability a ranking factor you should chase. Patents describe what a company considered, not what ships, and Google has never confirmed a link churn penalty.

What the claims point at is narrower and more useful. The concern is not that links change. It is that the relationship between an anchor and its destination stops making sense.

Anchor drift is the real risk

Claim 32 is the interesting one. It describes a page whose content has moved away from the anchor text pointing at it.

That happens constantly, and almost always on internal links rather than backlinks. You write a post about a 2023 model, forty posts link to it with the anchor naming that model, then you update the page to cover the 2026 version. The page is current. Every anchor pointing at it now describes something that is no longer there.

Nothing broke. Nothing 404s. The signal just quietly stopped matching the destination.

The links themselves decay too. Posts get deleted, slugs get rewritten, and sites you linked to go offline, so a link that worked two years ago becomes a dead end while the page around it still looks fine.

This is the version of instability that actually costs you. Not churn, but links that no longer resolve and anchors that no longer describe anything.

The practical answer is not to freeze your links. It is to know when they stop being accurate.

Three things are worth checking on any site past a few hundred posts.

Which anchors you have used, and where they point. If one phrase points at two different pages, you have told search engines those pages compete. If one phrase appears forty times, it stops reading like writing.

An anchor report makes drift visible before it becomes a pattern.

Linkilo’s anchor text report lists every phrase in use with its destinations, which is the fastest way to spot both problems.

Which links have stopped resolving. A broken link checker that scans on a schedule catches rot as it happens rather than during an audit two years later.

Whether your URL changes left chains behind. Every slug change adds a redirect, and redirects stack into chains where one click travels three addresses. Linkilo flattens those back to a single hop.

The honest limit is that none of this is a ranking lever. It is maintenance, and maintenance is invisible when it works. Linkilo is also WordPress only, so if you are elsewhere you will need a crawler to do the same job.

The short answer

Link stability is not a Google ranking factor in any form you should optimise for. Update your links whenever the content calls for it.

But the patents are not as empty as the popular reading suggests. What they describe is a system that notices when anchors and destinations drift apart, which is a real problem on any site that has been publishing for a few years.

Change your links freely. Just keep track of what they say and where they go.

Common questions

Does Google penalise sites for changing links often?+

There is no evidence of a link churn penalty. The 2005 patent application described one, the granted version dropped the phrase, and Google has never confirmed it exists. Change links when the content calls for it.

Is link stability about my backlinks or my own links?+

The patent is about your own outbound links. Most articles arguing it is a myth are talking about backlink longevity, which is a different thing and outside your control. The part you can act on is the anchors and links on your own pages.

What is anchor drift?+

It is when a page changes but the links pointing at it do not. You update a post to cover a newer version of something, and every anchor still names the old one. The link works, it just no longer describes the destination. The granted patent covers exactly this case in claim 32.

How often should I audit internal links?+

Quarterly is enough for most sites. Check which anchors are in use and where they point, which links have stopped resolving, and whether slug changes have left redirect chains. On a site that publishes weekly, a scheduled scan handles it without an audit.
