Half Your Links Won't Survive the Decade — Here's Which Ones Are Already on Death Row

Imagine spending weeks building out a resource library — blog posts, research citations, product pages, social profiles — only to come back two years later and find that nearly half of it leads nowhere. No warning. No redirect. Just a cold, blank error page where something useful used to live.

This isn't a hypothetical. Studies tracking URL longevity across the web have consistently found that somewhere between 35% and 50% of shared links become inaccessible within five years. Some research puts the half-life of an average URL at under two years. The internet, it turns out, is a lot more fragile than it looks.

At LinkFrog, we think about links constantly — how they're shared, tracked, and (too often) forgotten. So we dug into the data on link decay to figure out which URLs are most likely to go dark, and which ones actually hold up over time. The results might change how you think about every link you share.

What "Link Decay" Actually Means

Link decay — sometimes called link rot — happens when a URL that once pointed to live content stops working. This can happen for a bunch of reasons: the page gets deleted, the domain expires, a company restructures its website, a platform shuts down entirely, or content gets moved without a proper redirect in place.

The result is always the same: someone clicks your link and gets nothing. A 404. A blank screen. A parked domain selling cryptocurrency. Whatever goodwill or value that link was supposed to deliver? Gone.

The tricky part is that decay doesn't announce itself. Links don't send you a farewell email. They just quietly stop working, often long after you've forgotten you shared them.

The Fastest-Dying Links on the Web

Not all links decay at the same speed. Certain content types are almost guaranteed to have a short shelf life.

News articles and media coverage are among the most volatile. Major outlets regularly prune their archives, restructure their CMS, or put older content behind paywalls. A link to a news story from three years ago has a surprisingly high chance of redirecting to a paywall or returning a 404 — especially from regional publications and local TV station websites, which tend to have less stable web infrastructure.

Social media profile links and posts are notoriously unreliable. Twitter/X has restructured URLs multiple times. Facebook post links break constantly as privacy settings change or accounts get deactivated. Instagram posts vanish when accounts go private or get removed. If you're linking directly to a specific social post rather than a stable profile page, assume it has a short lifespan.

E-commerce product pages are another graveyard. Products get discontinued, SKUs change, seasonal items disappear. If you've ever clicked a link in an old email campaign that sent you to a "product not found" page, you've experienced this firsthand. For affiliate marketers and content creators who rely on product links for income, this is a genuine financial problem.

Government and academic URLs actually hold up better than most people expect — but they're not immune. Reorganizations at federal and state agencies frequently break old links, and university web pages get restructured when departments merge or faculty leave.

The Links That Actually Last

Some link types have a much better survival rate, and understanding why can help you build more durable digital assets.

Established nonprofit and institutional domains tend to be stable. Organizations like the CDC, major universities, and well-funded nonprofits invest in web maintenance and redirect management. Their links aren't bulletproof, but they're more reliable than most.

Wikipedia is one of the most link-stable destinations on the internet. Its community actively maintains pages, updates URLs, and manages redirects. Linking to a Wikipedia entry is about as safe a bet as you'll find.

Archived content via the Wayback Machine (web.archive.org) is, paradoxically, one of the most permanent link destinations available. Once something is archived, it stays archived. If you're citing important research or referencing a page that might change, an archived URL is a smart fallback.

Owned domains with active maintenance — meaning your own website or a platform you control — are only as stable as your commitment to keeping them alive. But at least you're the one holding the keys.

Which Industries Lose Links Fastest

Industry matters more than most people realize when it comes to link decay.

Retail and e-commerce see some of the highest link mortality rates, driven by constant product turnover and frequent site redesigns. Fashion brands in particular restructure their URLs seasonally.

Startups and tech companies are unpredictable. A startup that raised a Series A last year might be acquired, pivoted, or shut down within 18 months. Links to their blog posts, product pages, or documentation can vanish overnight.

Media and publishing remains volatile, especially as the industry continues consolidating. When a publication gets acquired or shut down, its entire URL structure often disappears with it.

Healthcare and finance, by contrast, tend to maintain more stable web presences — largely because regulatory requirements push these industries toward better content governance.

How to Figure Out Which of Your Links Are at Risk Right Now

Here's a practical framework for auditing your most vulnerable links before they go dark.

Age is your first filter. Any link you shared more than two years ago deserves a spot-check. Pull your old email campaigns, your social archives, your published blog posts, and start clicking. You might be surprised what's already broken.

Platform dependency is your second red flag. If a link relies on a third-party platform — a specific social post, a news article, a startup's blog — it's inherently more fragile than a link to content you own or control. Flag these for closer monitoring.

Domain age and stability matter. A link to a domain that's been around for 15 years and belongs to a major institution is more likely to survive than a link to a two-year-old startup's subdomain. Tools like WHOIS lookups can give you a quick read on domain history.

Redirect chains are a warning sign. If a URL already redirects once or twice before landing on the destination, that chain is one step closer to breaking. Each redirect is a potential failure point.

What You Can Actually Do About It

Knowing your links are fragile is only useful if you do something with that information.

For your most critical links — the ones embedded in high-traffic content, live campaigns, or long-term resource pages — using a link management platform to create short, tracked URLs gives you a layer of control you wouldn't otherwise have. When a destination URL changes or breaks, you can update where the short link points without touching every place you've already shared it. That's a huge deal for anyone managing links at scale.

For archival purposes, proactively saving important pages via the Wayback Machine before you link to them gives you a permanent backup you can reference if the original disappears.

And for ongoing monitoring, setting up periodic link audits — even just a quarterly pass through your most-shared URLs — catches decay early enough to actually fix it.

The Bigger Picture

The web feels permanent. You share something, it lives at a URL, people click it. But underneath that surface, there's constant churn — domains expiring, companies folding, platforms restructuring, content disappearing. The links you're sharing today are already on a clock.

That doesn't mean you should stop sharing links. It means you should share them smarter — with a system behind them that gives you visibility, flexibility, and a fighting chance of keeping your most valuable digital assets alive long after you've moved on to the next campaign.

The graveyard is real. But with the right habits, your links don't have to end up in it.
