Content decay
The slow drop in traffic a page suffers over time as it ages and competitors update theirs.
In depth
What it really means
Content decay is the gradual decline in a page’s traffic and rankings after it peaks. Nothing broke. Competitors published fresher takes, your stats aged out, the SERP grew an AI Overview, and a page that used to win slipped.
Decay is predictable, which is what makes it manageable. Caught at 20% down, a refresh usually recovers the position within weeks. Caught at 70% down, the page has usually lost its rankings to a competitor who now has months of engagement data behind them, and recovery costs far more.
Decay rate = ((peak monthly organic sessions − current monthly sessions) ÷ peak) × 100
Run this quarterly against every page that has been live more than six months. The action thresholds most teams settle on:
| Decay rate | What it means | Action |
|---|---|---|
| Under 15% | Seasonal noise | Ignore |
| 15% to 35% | Early decay, rankings intact | Refresh now, cheapest fix |
| 35% to 60% | Losing page one | Full refresh plus internal link push |
| Over 60% | Displaced | Rewrite, merge, or prune |
Decays fast vs decays slow
Fastest: pricing pages, tool roundups, “best X in [year]” posts, statistics posts. Often 40% down within 12 months.
Middle: how-to guides tied to a specific product UI, integration posts.
Slowest: definitions, frameworks, opinion pieces with a durable argument. Glossary entries sit here, which is part of why they are worth maintaining.
Pros & cons
Pros
- Turns a vague “our traffic is down” into a ranked list of pages to fix.
- Refreshes cost a fraction of new pieces and recover faster, since the page already holds links and history.
- Gives you an honest read on which topics you have actually lost.
Cons
- Session data alone misleads. A page can decay in traffic while holding rankings, because an AI Overview absorbed the clicks.
- Some decay is correct. A post about a discontinued feature should decay.
- Chasing every decaying page crowds out new publishing, and a program that only refreshes stops growing.
The mistake people make
Measuring decay in sessions only, in a year when sessions are falling across the board for reasons that have nothing to do with your page. Pair the session number with average position from Search Console. Traffic down and position steady means the SERP changed and the fix is snippet and citation formatting. Traffic down and position down means a competitor overtook you and the fix is a real refresh.
Best practices
- Track organic sessions and average position per page, together, monthly.
- Act on multi-month trends, not single dips.
- Refresh before the page falls off page one, since recovery gets much harder after.
- Prioritize by business value, not by size of decline.
- Put a standing quarterly review on the calendar so decay never accumulates quietly.
- Retire or redirect pages whose topic genuinely died.
FAQs
What causes content decay?
Aging stats, fresher competitors, shifting search intent, and new SERP features taking the clicks. The page did not break, the context moved.
How do I spot content decay?
Compare each page’s current monthly organic sessions to its peak. A steady multi-month decline over 15% is the signal.
How do I fix decay?
Usually a content refresh: update data, examples and angle, improve internal links, keep the URL.
Is decay avoidable?
No. It is the default state of a published page. A refresh cadence keeps it from compounding.
Which pages decay fastest?
Anything tied to statistics, tools, pricing or a named year. Those can lose 40% in twelve months without anyone touching them.
