1. Upload a page export

Accepted logical columns: date, page, clicks, impressions, CTR, and position. Header aliases are normalized, and CTR is recalculated from clicks and impressions.

What this is good for
A weekly refresh queue for pages losing clicks, visibility, or snippet efficiency.
What this does not claim
No technical SEO diagnosis, no query-level attribution, and no content rewriting.

3. How Decay score works
The score is intentionally transparent. It combines relative click loss, absolute click loss, impression decline, CTR decline, and ranking deterioration. Recent versus previous windows are fixed at 28 days each.
rawScore = 35 × clickLossRate + 25 × absoluteClickLossRate + 15 × impressionLossRate + 15 × ctrLossRate + 10 × positionWorseningRate decayScore = round(rawScore)
Reason tags and refresh actions
  • possible-deindex → Check indexing, canonicals, robots, and recent template changes before refreshing content.
  • rank-down → Refresh headings, examples, and internal links to better match current search intent.
  • ctr-down → Rewrite title and meta description, tighten the intro, and improve snippet clarity.
  • demand-down → Update stale sections, dates, examples, and external references to restore freshness.
  • mixed-decay → Run a full refresh: improve intent coverage, update facts, and rework snippet hooks.
