Why your YouTube description links stop working after a few months

Someone comments "this link is dead" on a video from last winter. You check, and they're right.

YouTube didn't do anything here. Descriptions don't expire and YouTube never touches the links inside them after you publish. Whatever broke, broke on the other end - the destination itself, or something sitting between your description and it. The tricky part is that "broken" can mean several different things, and each one needs a different fix.

The product page is just gone

This is the single most common cause, by a wide margin. Amazon listings get discontinued, merged into a new ASIN when a product gets a minor revision, or pulled from sale entirely. Your link was never broken by anything you did - it's simply pointing at a page that no longer exists on the retailer's side.

Older videos are hit hardest here, and not because anything about them is different. It's purely a function of time. The longer a video's been up, the more chances the specific product it links has had to go out of stock permanently, get replaced by a newer model, or be delisted by the retailer without any notice to anyone linking it.

This is also the cause that's easiest to mistake for something more serious. A dead product page and a broken redirect chain look identical from a viewer's perspective - both end in an error or a dead end - but they call for completely different responses. One means finding a new link for a similar product. The other means fixing the plumbing.

Your shortener service changed or disappeared

If you used a free link shortener, you're depending on a company that owes you nothing in return for that dependency. Free shortener services shut down, get acquired by a company with different priorities, or change their terms and redirect behavior with little to no warning.

When that happens, every link you ever created through that service can go dead at once, across your entire back catalog, on the same day. This is the version of link rot that actually does real damage, because it's not one video failing on its own - it's potentially years of uploads failing simultaneously, and you often don't find out until a viewer tells you, sometimes weeks after it happened.

It's worth periodically checking whether the shortener service you're relying on is still actively maintained, still profitable enough for its owners to keep running, and still has the same terms it had when you started using it. None of that is something most creators think to check until after something's already broken.

Your affiliate tag expired or got reset

Some affiliate programs re-issue tracking IDs periodically, or deactivate ones that go quiet for long enough. If your tag stops being valid, the link itself might still resolve to a perfectly real, perfectly functional page - it just no longer earns you anything, which looks identical to "broken" from the outside even though the underlying mechanics are completely different.

This distinction matters because the fix is different too. A dead product page needs a new link entirely. An expired tag needs the same link, re-tagged - the destination was never the problem. Worth specifically checking this if a link loads fine but income tied to it has quietly dropped to zero without any comments about a broken page.

The retailer restructured its URLs

Large retail sites redesign occasionally, sometimes as a minor tweak and sometimes as a full platform migration. When that happens, old URL patterns sometimes get redirected properly to their new equivalent, and sometimes they just don't - it depends entirely on how carefully the retailer's own engineering team handled backward compatibility, which is completely outside your control or visibility.

A retailer migrating to a new site structure can silently break thousands of old product links across the internet without any announcement to the creators and publishers whose content depends on those links still working. You won't get a heads-up. The only real defense is noticing the pattern early, on your side, before too many videos are affected.

Seasonal and limited-run products are a special case of the same problem

Some products aren't discontinued forever - they're just seasonal, or a limited run that sells out and doesn't come back until the next cycle, if it comes back at all. A holiday gift guide linking a specific limited-edition item will look completely broken by February, not because anything failed, but because the product simply isn't for sale right now.

This gets confusing because the same link can flip between "working" and "broken" repeatedly over a year, depending entirely on the retailer's stock cycle rather than anything happening on your end. If you make a habit of gift guides or seasonal content, it's worth expecting this pattern specifically rather than treating every seasonal dead link as a surprise each time it happens.

A less obvious cause: regional availability

A link that works perfectly for you can fail for a meaningful chunk of your audience if the product simply isn't sold, or isn't in stock, in their region. This isn't a broken link in the traditional sense - it resolves fine, just not to something purchasable for that specific viewer.

This one's easy to miss because it never shows up as a dead link from your own testing. You'll open it, see the product, confirm everything looks fine, and move on - never realizing a chunk of international viewers are hitting an "unavailable in your region" message on the exact same URL. If your audience is international and a link seems to be underperforming without any obvious reason, regional availability is worth ruling out before assuming something else broke.

A worked example

Say a channel published a "best budget tripods" video eighteen months ago, linking three products. Today, one link 404s outright, one redirects to an unrelated accessory, and one works exactly as it always did.

The first is almost certainly a straightforward discontinued listing - the product itself is gone, and the fix is finding a current equivalent to replace it with, since there's nothing left on the retailer's side to repair. The second is more interesting: a redirect landing on an unrelated product usually means the retailer restructured its catalog and the old URL got reassigned to something else entirely, rather than pointing nowhere. That's not fixable by waiting - it needs a fresh link found manually, and the old one can't be trusted to self-correct.

The third link, the one still working, isn't actually proof nothing changed. It just means the product and its URL happened to survive whatever changes hit the other two - possibly because it's a more established item less likely to be discontinued, or because that particular retailer handled its migration more carefully. None of that visibility exists until you actually click through each one individually. Looking at the video's overall click count wouldn't have shown any of this - all three links pool into the same click number regardless of whether they still lead anywhere.

Checking links efficiently instead of one by one forever

Manually opening every link on every video isn't sustainable past a certain catalog size, so the goal is narrowing down what actually needs checking rather than checking everything with equal frequency.

Prioritize by traffic, not by age or gut feeling - a five-year-old video nobody watches anymore matters less than a two-year-old video still pulling steady search traffic every week. Batch your checks by publish quarter rather than checking video by video in upload order; products from the same era tend to fail together, since they were often sourced from the same retailer catalogs at a similar point in that catalog's lifecycle. And keep a simple log of when you last checked each video's links, even something as basic as a spreadsheet column - without it, you end up either re-checking things you already confirmed recently or, worse, assuming something's fine because you vaguely remember checking it, when that check was actually over a year ago.

Symptom to likely cause

What you're seeing	Most likely cause
One link dead, rest of the same video fine	Product discontinued or listing removed
Every link from one time period dead, across several videos	Shortener issue - check if the provider's still operating
Link loads, but you suspect you're not earning from it anymore	Tag expired or reset, not the link itself
Link redirects to something generic or unrelated	Retailer restructured URLs, old redirect never set up correctly
Very old video's links dead, recent ones fine	Ordinary rot - older content has simply had longer to be affected
International viewers report issues, you can't reproduce it	Regional availability - the product isn't purchasable where they are

The audit that's actually worth doing

Skip your entire catalog and start with the videos still getting real, ongoing traffic. A dead link nobody sees doesn't cost you anything meaningful. A dead link sitting on your evergreen top performer costs you a little bit every single day it stays broken, unnoticed.

Open the actual published URL yourself, in a private browser window, rather than trusting memory or assuming it's fine because it was fine last time you checked. Watch where it actually lands after any redirects resolve, not just whether something loads. If the page loads but earnings from it feel off relative to its click volume, that's a tag problem, and the fix for that is completely different from replacing a dead link - re-tag the same destination rather than hunting for a new one.

If you built your link structure on a free shortener, check whether that service is even still operating in its original form before assuming the fault sits with you or your video. And once you've identified what actually broke, fix it by editing the description directly - there's no need to touch the video itself, re-upload anything, or otherwise disturb content that's already published and possibly still ranking.

A quarterly pass through your best-performing older videos is enough cadence for most channels. There's no real benefit to checking everything constantly, and doing so mostly just trains you to react to noise rather than catching the failures that actually matter.

Why this deserves more attention than it usually gets

If your channel pulls steady search traffic on tutorials or reviews, your older uploads are doing more ongoing work than a quick glance at their age would suggest. That evergreen pattern compounds slowly over months, sometimes years, which also means a dead link sitting unnoticed on a still-ranking video isn't a small, contained problem limited to that one video's numbers.

It's daily traffic hitting a dead end, invisibly, for as long as nobody catches it - which in practice often means until a viewer happens to leave a comment about it, at which point you have no idea how long the link had already been broken before that comment showed up. There's no dashboard alert for this by default. It relies entirely on either your own periodic checking or someone else noticing and telling you.

Preventing this instead of just catching it faster

The audit habit above catches problems after they've already cost you some traffic. The more durable fix is structural: route every link through one destination you control, so that when the underlying product page changes, moves, or disappears, you update it in exactly one place instead of hunting down and re-editing descriptions across every video that ever linked it.

This doesn't prevent the underlying causes above from happening - products still get discontinued, retailers still restructure their sites. What it changes is the blast radius. Instead of a dead link on forty different videos requiring forty separate description edits, it becomes one redirect update that fixes all forty at once, the moment you notice.

It also changes how fast you find out in the first place. A shared destination is one thing to spot-check, rather than forty separate URLs scattered across forty separate descriptions written at forty different points in time, using whatever link format felt convenient that particular week. The consolidation is what makes a quarterly audit actually feasible instead of a task that quietly gets postponed indefinitely because it feels too large to start.

What to actually do once you've found a dead one

Finding the broken link is only half of it - what you do next depends on which cause it turned out to be, and treating all of them the same way wastes effort.

If the product's genuinely discontinued, look for the closest current equivalent from the same brand or category rather than leaving the link dead or removing it entirely; a close substitute keeps the video useful and keeps the link earning, even if it's not the exact item originally reviewed. If it's a shortener problem affecting multiple videos at once, prioritize fixing your highest-traffic videos first and work down the list, rather than trying to fix everything in one sitting - a partial fix on your best-performing content beats a slow, complete fix that takes weeks to finish. If it's a tag issue rather than a dead page, the destination is already fine, so the only change needed is re-tagging the same URL, which takes seconds once you've confirmed that's actually what happened. And if it's regional availability, there may not be a fix at all beyond acknowledging that some percentage of any audience simply won't be able to buy through that specific link, which is a normal limitation rather than something broken to chase down.

Frequently asked questions

Does YouTube ever break links in old descriptions on its own?

No. YouTube doesn't modify description content or the links inside it after publishing. If a link is dead, the cause is on the destination side or in whatever service sits between your description and that destination - never YouTube itself.

How often should I check my old links?

A quarterly pass through your top-viewed evergreen videos is reasonable for most channels. Checking everything constantly isn't necessary and mostly just wastes time - focus on the videos still pulling meaningful, ongoing traffic.

My link works but I don't think I'm getting credit anymore. What's wrong?

That's usually an expired or reset affiliate tag, not a broken link. The destination page loads fine; the tracking behind it just isn't valid anymore, which is a different problem with a different fix than replacing the link entirely.

Is it safe to use free link shorteners for long-term content?

Riskier than most creators assume, specifically because you have no visibility into that company's future decisions. Free services can shut down or change behavior with no notice, and when they do, it affects every link you've ever created through them simultaneously, not just one video.

Should I edit old video descriptions to fix dead links?

Yes - this is exactly what description editing exists for, and it doesn't require re-uploading or otherwise touching the video itself in any way.

How do I know if a redirect chain is the actual problem?

Click through the link yourself and watch where it actually lands, not just whether a page loads at all. If it resolves to a homepage, a generic search results page, or an outright error, something broke in the redirect chain - not necessarily anything about your original link or how you set it up.

Can a link be "broken" only for some viewers and not others?

Yes - regional product availability is the most common cause of this. The link resolves fine for you and for most of your audience, but shows as unavailable for viewers in regions where the product isn't sold or stocked.

Why does a link that worked in December stop working in February?

Likely a seasonal or limited-run product. It's not broken in the traditional sense - it's simply out of stock until the next cycle, and may or may not come back depending on the retailer's plans for that specific item.

Is there a way to prevent this instead of just catching it after the fact?

Routing every video's link through one destination you control is the closest thing to prevention. It doesn't stop products from being discontinued, but it means fixing one is a single update instead of a separate edit on every video that ever linked it.

Why a quick fix now beats a big cleanup later

There's a temptation to let a handful of dead links pile up and plan one big cleanup pass eventually. In practice, that pass rarely happens, because it keeps growing in scope every month it's delayed, until it feels too large to start at all.

Fixing a dead link the moment you notice it - whether from your own audit or a viewer's comment - takes a few minutes. Fixing forty of them at once, months later, after finally forcing yourself to sit down and do it, takes an afternoon you'll keep putting off. The math favors small and frequent over large and rare, even though large and rare feels more efficient in the abstract.

The takeaway

Links don't rot on their own. Something on the other end - the product listing, the shortener service, the affiliate tag, or the retailer's URL structure - changed, and your description is simply still pointing at the version of reality that existed when you published it.

Audit your best-performing older videos first, figure out which of these causes you're actually looking at before assuming the worst, and fix the description directly once you know. No re-upload needed, and if you've routed things through a single controllable destination, often no more than one edit needed at all.

Want links routed through one place you control, so a dead destination is a single edit instead of a re-audit across dozens of videos? GoloLink's free tier handles that.
