Content Decay Detector

Paste a published article or URL with its age and AI scores content freshness, flags stale claims, identifies missing context, and prioritizes refresh work.

How it works

A short, focused workflow — input, run, read the result.

  1. Paste the article

    Add the article text or URL you want to audit for decay.

  2. Add publish context

    Include publish date, last updated date, target keyword, or traffic decline notes.

  3. Generate the audit

    Review freshness score, stale claims, missing context, and recommended updates.

  4. Refresh strategically

    Update high-priority sections first, then recheck rankings and impressions.

What is content decay, and why does it silently drain organic traffic?

Content decay is the gradual loss of organic visibility as a page becomes outdated, competitors improve, or search intent shifts. Most sites lose 10-15% of traffic a year to decay and never notice because the drop is spread across hundreds of pages.

Content decay is what happens when a 2023 article on 'best email marketing tools' starts ranking for 2025 queries but still recommends 2023 winners. The page is technically fine. The page is functionally wrong. Google notices before you do: rankings slip from position 3 to position 7 over 6 months, impressions stay flat, and clicks quietly fall by 25%. The decay detector finds these pages before the damage compounds.The decay threshold that matters is 1.5% month-over-month click decline sustained over 90 days. A single bad month is noise. A quarter of consistent decline is decay, and it almost always means the content needs a refresh, not a rewrite. Refreshing the top 20% of decaying pages on a 500-page site typically recovers 80% of the lost traffic within 90 days of re-indexing.The tool scores any published article on a 0-100 freshness scale using AI, flags claims that look stale, identifies missing context competitors now cover, and returns a prioritized refresh checklist. You paste the article text or URL, add the publish date and target keyword, and get a fix list ordered by impact. Refresh the high-priority sections first, then recheck rankings in 30 days.
