What Topical Drift detects (and scores by severity)
- 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
