Real outcomes from real users
"Consolidated 47 zombie pages, fixed our Core cluster drift, and rebuilt internal linking. Traffic to our main category jumped from 8K to 35K/month."
"Audit revealed 23 pages cannibalizing our main product keyword. After consolidation, we jumped from #8 to #2. Added $47K in pipeline value in Q1."
"White-label reporting lets us charge $299/mo per client for drift monitoring. Paid for itself in 2 weeks. Now running monthly audits for 12 clients."
What Topical Drift detects
- Radial drift map + semantic zones: visualize what's Core/Focus/Extended/Peripheral and track drift over time
- Cluster architecture issues: weak clusters, isolated content, overbuilt topics, broken silos, cannibalization
- Internal link meaning mismatch: when anchor text + context contradicts destination page semantics
- Zombie pages: indexed pages with high impressions (500+), poor position (30+), and zero clicks
- Orphan pages & "lost cows": undiscoverable pages with 0-1 internal links
- Underperforming core content: pages in your Core zone that should rank but don't
- CTR optimization opportunities: pages with high impressions but low click-through rates
- Thin content signals: pages lacking the depth/entities needed to compete
- Meta tag issues: title/description optimization opportunities
- Structural analysis (HDR): heading density, section variance, over-segmentation, chunkability
- Crawl/extraction cost: boilerplate ratio, DOM complexity, content-to-noise scoring, schema gaps
- Growth opportunities: easy wins, expand winners, strengthen clusters

Pricing questions
Yes, absolutely. Crawl as often as your workflow requires. We only ask that you use the tool reasonably (no automated abuse).
Most users crawl 1-2 times per month. Power users running active remediation projects might crawl weekly. Both are perfectly fine under fair use.
Free gives you the diagnostic overview:
- ✅ Drift map showing your semantic zones
- ✅ Issue detection: "You have 23 zombie pages in Core zone"
- ✅ Cluster visualization with coherence scores
- ✅ Severity breakdown (Critical/High/Medium)
- ✅ Affected page counts per issue
Paid plans add the remediation data:
- ✅ Exact URL lists for each issue (which 23 zombie pages)
- ✅ Per-page diagnostics (why each page is a zombie, health score, HDR analysis)
- ✅ Internal linking recommendations with similarity scores
- ✅ CSV exports for your team
- ✅ Historical tracking to measure improvements over time
Paid plans (Starter/Pro/Agency): Give you ongoing access to diagnose issues and track improvements. You see the problems and have the data to fix them.
Topical Drift Audit: Delivers a strategic remediation blueprint — what to fix first, why it matters, and a sequenced 30/60/90 execution plan. Think of it as hiring a consultant who analyzes your crawl data and creates your strategy.
Best for: Teams that want expert guidance on prioritization, consolidation strategy, and internal linking architecture. The Audit includes 90 days of Professional access so you can execute the plan and track results.
We're not competing with those tools — we solve different problems:
Ahrefs/SEMrush ($129-139/mo): Backlink analysis, keyword research, rank tracking, technical audits
- ❌ Don't detect semantic drift or content architecture issues
- ❌ No embeddings-based clustering or cannibalization detection
- ❌ No zombie page analysis (impressions + position + CTR context)
Screaming Frog ($259/year): Technical crawling (broken links, meta tags, redirects)
- ❌ No semantic understanding of content
- ❌ No content strategy guidance
- ❌ Pure technical, doesn't understand topic relevance
Topical Drift: Content architecture + semantic analysis
- ✅ Embeddings-based drift detection (which pages are off-topic)
- ✅ Cluster cannibalization (which pages compete)
- ✅ Zombie detection with GSC context
- ✅ HDR/structural analysis for AI retrieval optimization
- ✅ Internal linking recommendations based on semantic similarity
Pricing context: We replace $2,500-5,000 manual content audits. At $49-149/mo, you get ongoing monitoring instead of a one-time deliverable. Most users recover $400-1,600/mo in traffic value from zombie consolidation + CTR fixes alone.
