Content Decay

Content decay is the gradual decline in a page’s organic traffic and rankings over time. A page that once performed well slowly slips down the results, often without anyone noticing until traffic has fallen significantly.

Why content decays

  • Information goes out of date: prices, statistics, tools, laws and best practices change.
  • Competitors publish better content: newer, more detailed or more useful pages overtake yours.
  • Search intent shifts: Google starts preferring a different type of page for the query (Search Intent).
  • SERP changes: new features such as AI Overviews, videos or ads push organic results down (Zero-Click Searches).
  • Declining interest: the topic itself becomes less searched.
  • Lost links: pages that linked to yours are removed or updated.
  • Internal changes: fewer internal links after redesigns, or new pages competing for the same keyword (Keyword Cannibalisation).

How to spot content decay

  1. Google Search Console: compare clicks and impressions for each page over the last 6 to 12 months against the previous period. Sort by the largest drop.
  2. Check positions for the page’s main queries to see whether rankings fell or demand fell.
  3. Analytics: look for landing pages with steadily falling organic sessions and conversions.
  4. Rank tracking: watch for slow downward trends on important keywords.

Separate decay from sudden drops. A gradual decline over months suggests decay; a sharp fall on a specific date suggests an algorithm update or technical issue. My guide to the causes of a Google rankings drop covers sudden falls.

How to refresh decaying content

  1. Re-check the search results to see what currently ranks and why.
  2. Update facts, figures, screenshots and examples.
  3. Add missing subtopics and questions competitors now answer.
  4. Improve structure with clearer headings, summaries and tables.
  5. Add first-hand experience and expert insight (E-E-A-T).
  6. Refresh the Title Tag and Meta Description to improve click-through rate.
  7. Strengthen Internal Linking from newer, relevant pages.
  8. Update the published or modified date honestly, only when meaningful changes are made.
  9. Request indexing in Search Console after significant updates.

When not to refresh

If a page’s topic no longer matters to your business or audience, consider merging it with a related page or removing it instead (Content Pruning). Not every old page deserves to be saved.

Preventing content decay

  • Schedule regular reviews of your most valuable pages, at least every 6 to 12 months.
  • Keep a content inventory with last-updated dates and owners.
  • Avoid putting dates or years in URLs for evergreen content.
  • Monitor competitors for your top keywords.

Refreshing an existing page that already has links and history is often faster and cheaper than creating something new, which makes decay management one of the best returns in SEO.

Key Takeaways

  • Content decay is the gradual loss of traffic and rankings over time.
  • Outdated information, stronger competitors and changing intent are the usual causes.
  • Compare page performance over 6 to 12 months in Search Console to spot it.
  • Refreshing an existing page is often faster than creating a new one.
  • Review your most valuable pages at least once or twice a year.
