Free scans up to 500 pages/site — then unlock the exact URLs and page-level diagnostics.

Start with a high-level scan that shows your radial drift map, cluster visualization, and issue counts across duplicates, thin content, orphans, zombies, underperformers, linking gaps, and more. Upgrade to unlock affected URL lists, then unlock per-page details and exports. Need a complete remediation blueprint? Add the Topical Drift Audit.

✨ Free scan includes
  • Free scans (fair use)
  • Up to 500 pages per site
  • Radial drift map + clustering
  • Issue counts (high-level)
  • Unlock to see affected URLs + page details
Unlimited scans (fair use) on paid plans
Scan weekly during projects, rescan after fixes, or check drift after content updates — no artificial monthly limits.
Run a free scan
See your radial drift map, clusters, site focus, and issue counts (duplicates, thin pages, orphans, zombies, underperformers, linking gaps, and more).
Unlock affected URLs
Upgrade to reveal exact URL lists for each issue category (e.g., which pages are thin, orphaned, duplicate, underperforming, etc.), plus filtering and exports.
Add the Audit (optional)
Get a done-for-you remediation blueprint: executive report, priority sequencing, consolidation recommendations, internal link strategy, and a clear 30/60/90-day plan.
Important: The app helps you diagnose issues and track improvements. The Audit delivers a strategic execution sequence (what to fix first and why).

What Topical Drift detects (and scores by severity)

Free scans show maps + counts. Paid plans unlock URLs, page diagnostics, and exports. The Audit turns findings into a sequenced remediation plan.
Map → Clusters → Fix list Counts → URLs → Page detail
  • Radial drift map + semantic zones: see what’s Core/Focus/Extended/Peripheral and which pages drift over time
  • Cluster architecture: weak clusters, isolated clusters, overbuilt clusters, broken silos, and overlap/cannibalization patterns
  • Internal link meaning mismatch: when anchor + surrounding context contradicts the destination page’s meaning
  • Orphans & “lost cows”: pages that are weakly linked, undiscoverable, or stranded outside hubs
  • Zombies & underperformers: indexed visibility with little/no clicks, or core pages losing traction
  • CTR opportunities: high impressions with weak CTR (rewrite intent match + snippet assets)
  • Thin content signals: pages that don’t cover the intent/entities needed to compete
  • Meta tag issues: titles/descriptions that don’t support the winning intent (length, clarity, mismatch)
  • Deep structure analysis (HDR): heading density ratio, section variance, “bullet spam”, over-segmentation, and chunkability
  • Crawl/extraction cost: boilerplate load, DOM complexity, content-to-noise ratio, missing schema, and extraction blockers
  • Growth opportunities: easy link wins, expand winners, strengthen core clusters, breakout pages

Topical Drift Audit

The app shows you what’s wrong. The Audit tells you what to do first—with a fix sequence you can execute.

  • Executive report + narrative analysis
  • Prioritized remediation sequence (30/60/90)
  • Consolidation & cannibalization plan
  • Internal linking strategy built from semantic neighbors
  • Structure/HDR cleanup recommendations
