Content Decay: How to Spot It, Diagnose It and Fix It

Pages that used to bring steady traffic often lose it slowly, and the site total hides it. This guide defines content decay with numbers, shows how to rule out seasonality and site-wide drops, diagnoses decay by what changed in search, and works through three pages with different fixes.

What content decay is

Content decay is the slow, steady loss of traffic on a page that used to perform well. It is different from a sudden drop: decay happens over weeks or months, page by page, often unnoticed because the site total is held up by newer pages.

A useful numeric definition: over the last 13 weeks, compare the average of the latest four weeks with the average of the best four weeks.

• Under 40% of peak: severe decay.
• Under 70% of peak, with a downward trend: decaying.
• Otherwise stable, or growing if the latest weeks trend up strongly.

Rule out the look-alikes first

• Seasonality: a "Black Friday checklist" peaks every November. Compare with the same weeks last year before calling it decay.
• Site-wide drop: if most pages fell at the same time, it is a tracking, technical or algorithm issue, not decay. See sudden drop in website traffic.
• Channel shift: if search visits fell but total visits did not, the page is fine; traffic moved elsewhere.

Diagnose by what changed

For decaying pages, look at the page's search data for the same weeks. The table below matches what changed with the likely cause and fix.

Open the page’s search data for the same weeks as the decline.

A worked example: three pages

Organic search visitors per week, 13 weeks (sample numbers):

• Setup guide: best four weeks averaged 1,250 visitors a week; latest four average 450, 36% of peak, severe. Search data: position steady at 3, impressions steady, CTR fell from 9% to 3%. The results page now shows an AI answer and a video carousel above it. Fix: rewrite the title and description around the specific question, add a short step list and a video, and accept part of the loss.
• Pricing comparison post: 800 → 520 a week, 65%, decaying. Position slid from 4 to 9; the post still lists last year's prices. Fix: update prices and screenshots, add the date, and add links from two newer posts.
• Glossary page: 300 → 240, 80%, stable. Normal variation; leave it.

Four weeks after the updates, the pricing post is back to position 5 and 690 visitors a week; the setup guide recovers to 640 a week.

Refresh, merge or leave

• Refresh when the topic still matters and the page has lost freshness or depth: update facts, examples, screenshots and the date; answer the question earlier.
• Merge when two of your pages compete for the same query; see keyword cannibalization.
• Leave stable pages and seasonal pages outside their season.
• Retire pages whose topic no longer matters; redirect if there is a close replacement. This is where a content audit helps.

Content decay in TapCub

Monitoring › Content decay looks at 13 weeks of visitors per page, one number a week, and compares the mean of the peak four weeks with the latest four. Statuses are growing, stable, decaying, severely decaying and not enough data (peak week under your threshold). The default channel is organic search; you can switch to all channels or AI sources. Results refresh hourly. Open a row to compare sources in the first four weeks of the decline with the latest four, to see whether only search dropped.

For position, impressions and CTR, connect Google Search Console or Bing in Monitoring › Search performance. Related: content performance metrics and how to improve organic search.
