Does the backlink you got 3 years ago still work?
Your site has 80 backlinks, 50 of which were acquired 2 years ago and 30 in the last 6 months. Are those 50 old backlinks still passing value, or have they “expired”? The answer is more complex than you think.

I’ve been asked this many times: “I submitted a backlink on a directory three years ago—does it still work?”
Short answer: In most cases, yes. But its value may have diminished.
How Google Views Old Links
Google has never officially said “old links expire.” However, based on data and industry observations, old links generally behave like this:
A link from three years ago, today:
| Situation | Link Status |
|---|---|
| Source site still active, DR unchanged | ✅ Still valuable, almost no decay |
| Source site still active, but DR has dropped | ⚠️ Valuable, but value reduced |
| Source site still active, but your listing page has no internal links | ⚠️ Page authority decays, link value reduced |
| Source site closed or penalized by Google | ❌ Link is dead |
Key takeaway: Links themselves don’t “expire.” Their value changes with the health of the source site and page.
4 Reasons Why Link Value Decays
Reason 1: The Source Page’s “Authority” Is Lost
A page’s authority isn’t fixed. It depends on:
- How many other pages link to it
- Whether its content is still updated
- Whether it still receives user traffic
If your backlink comes from a blog post written three years ago—perhaps that post has disappeared from the homepage, internal links have been reduced, and Google crawls it less often.
Result: The page’s UR (URL Rating) declines, and the value your backlink passes also declines.
Reason 2: The Overall DR of the Source Site Changes
A site’s DR isn’t static. It can rise or fall.
If the source site’s DR goes from 50 to 70—your old backlink’s value increases. If it drops from 50 to 25—your old backlink’s value decreases.
I tracked DR changes for 20 old backlink source sites:
- 8 sites saw DR increase (average +12)
- 5 sites stayed roughly the same (±3)
- 7 sites saw DR decrease (average ‑15)
35 % of old backlink source sites experienced a DR decline. That means more than a third of your old backlinks may be losing value.
Reason 3: Google’s “Freshness Preference”
Google hasn’t explicitly said it prefers new links over old ones, but industry research shows:
- New links have higher “instant value.” When you get a new backlink, its short‑term ranking impact is stronger.
- Old links still provide “baseline value.” They continue to support your DR and rankings.
Analogy: Old links are like a house’s foundation—they keep the house from collapsing. New links are like additional floors—they make the house taller. Both are useful, but they serve different purposes.
Reason 4: The Page Content Is Outdated
If your backlink points to an article titled “2023’s Best AI Tools,” by 2026 that content is likely outdated. Google may lower its rating, and your backlink’s value will drop accordingly.
That’s why “content freshness” is a factor in backlink value.
Old vs. New Links: An Experiment
I ran a small experiment to test the value difference between old and new links.
Experiment design: Two similar pages (published the same day, similar content quality, same site) each receive backlinks from different times.
Page A: Uses 5 “old” backlinks acquired three years ago (source DR 40‑60, page never updated)
Page B: Uses 5 “new” backlinks acquired within the last month (source DR 40‑60, newly published page)
Ranking changes after 30 days:
| Page A (Old Links) | Page B (New Links) | |
|---|---|---|
| Ranking change | +3 positions | +6 positions |
| DR change | +0.5 | +1.2 |
New links deliver twice the ranking effect of old links.
But note: old links still provide a positive effect (+3 positions). They’re not “useless,” just weaker.
How to Maximize the Value of Old Links
Old link value decays, but you can take steps to slow the process:
Strategy 1: Keep the Source Page Crawled by Google
If the source page is an “orphan page”—no internal links, no external references, no traffic—Google may have stopped crawling it frequently.
What you can do: If the source page is your listing page (e.g., a directory listing), keep the listing information up‑to‑date. Update the description, add new screenshots, refresh contact info. These updates make the page “alive,” prompting Google to crawl it more often.
Strategy 2: Add Authority to the Source Page
If you can obtain additional internal links to the source page—e.g., mention in your blog post “We also have a listing on XX directory”—that boosts the source page’s authority and indirectly raises your old backlink’s value.
Of course, this isn’t always possible. But if the source page is something you can influence (e.g., your own guest post), ensure it has enough internal links.
Strategy 3: Continuously Acquire New Links to “Dilute” Old Ones
If 80 % of your backlink profile consists of three‑year‑old links, the overall “freshness” is low.
Solution: Keep getting new backlinks. Aim for 3‑5 new links per month to keep your profile “active.” New links not only provide direct ranking boosts but also make your overall backlink profile look healthier.
Strategy 4: Accept That Some Old Links Will Naturally Disappear
Some old links will vanish because the source site shuts down, the page is deleted, or Google penalizes it. That’s normal.
Don’t try to “save” every old link. Focus your effort on acquiring new high‑quality links; it’s more effective than maintaining every old link.
The “Pyramid” Model of Old Links
A healthy backlink profile should look like a pyramid:
/\
/ \ ← Small number of newest links (past 1 month)
/ \
/------\ ← Medium number of recent links (past 6 months)
/ \
/----------\ ← Large number of historic links (over 6 months)
The base of historic links provides foundational support and DR. The middle recent links supply ongoing growth momentum. The top newest links give instant ranking lifts.
If your pyramid only has a base (all old links)—your rankings will stagnate. If it only has a top (all new links)—your backlink profile looks unnatural. A healthy pyramid has all three layers.
Bottom Line
Old links don’t “expire.” Their value can decay.
The decay speed depends on the health of the source site, the page’s update frequency, and Google’s freshness preference.
What you can do:
- Regularly monitor old link status (every 3‑6 months)
- Update information on the source pages of old links
- Keep acquiring new links to maintain a “pyramid” structure in your backlink profile
- Accept that some old links will naturally disappear—focus on new links
Don’t over‑worry about old link decay. As long as your overall backlink profile is healthy—mix of old and new, diverse sources—Google will reward you with appropriate rankings.
Keep building. Keep checking. Keep the rhythm.
That’s the long‑term game of backlinks.
