Refreshing content is not a one-size-fits-all exercise. The best programs use decay curves to decide what to revisit, when, and how much effort to apply.
What a decay curve is
A decay curve plots a page’s performance over time:
- traffic or impressions
- click-through rate
- engagement metrics
As a page ages, performance typically declines. The rate of that decline helps you prioritise refreshes.
The content refresh cadence model
Monthly quick checks
- Review top pages for traffic dips
- Fix obvious issues: outdated CTAs, broken links, stale stats
Quarterly metric review
- Evaluate clusters and service landing pages
- Refresh supporting content and internal links
Annual pillar rewrites
- Rewrite pillar content with new insights
- Update case studies, sources, and strategic positioning
How to prioritise using decay curves
Score pages on three dimensions:
- traffic decline rate
- commercial intent
- ease of refresh
Pages with fast decay, high intent, and low refresh effort are the highest priority.
Focus on business impact
Refresh the pages that contribute to leads, citations, or visibility for core services.
- service landing pages
- commercial blog clusters
- high-intent FAQs
Avoid refreshing low-value articles just because they are old.
Practical workflow
Step 1: classify pages
Group content by type:
- pillar pages
- service pages
- cluster posts
- reference guides
Each type has a different refresh cadence.
Step 2: track decay signals
Use analytics and search console to detect pages with:
- falling traffic
- shrinking impressions
- decreasing CTR
These are the pages whose decay curves are steepest.
Step 3: choose the refresh action
For each page use one of three actions:
- quick update: fix numbers, add current examples
- content expansion: add new sections, sources, FAQs
- rewrite: rebuild the page for a new search intent
Implementation tips
- Tag pages with last reviewed dates in your CMS
- Use automated alerts for declines greater than 20%
- Keep a running backlog of refresh actions aligned to business goals
Example cadence for service content
- Core service pages: review every 6 months
- High-value cluster posts: review every 3–4 months
- Evergreen guides: review every 12 months
If a page is still performing, a light refresh is often enough.
Why cadence matters
A predictable cadence keeps the team focused and avoids the all-or-nothing refresh sprint.
A disciplined refresh program is easier to sustain than chasing every traffic dip.
