Content Decay Detector

Score any blog for structural decay.

Paste a domain. We walk your sitemap, fetch each post, pull a Wayback Machine snapshot from 90 days ago, and surface the posts whose content signals are slipping — FAQs removed, schema thinned out, last-updated dates aged out, word counts shrunk. Each one tagged with a recommended action you can ship today.

Public signals only. No GSC. No login. Runs in your browser.

What this is. An honest structural-decay scan of a public blog. We compute four signals per post: freshness gap (days since last update), structural delta (Wayback snapshot diff — schema removed, FAQ blocks removed, word-count change), content thinness (current word count, schema gaps, FAQ presence), and internal-link orphaning. Each post gets a 0–100 decay score, a severity tag, and one recommended action.

What this isn’t. A traffic-decay tool. We don’t have your Search Console or an Ahrefs key, so we don’t fabricate traffic numbers. Where Wayback has no snapshot or freshness can’t be parsed, we mark the row insufficient data and skip the score — credibility of the whole tool depends on this.
