What Topical Drift detects

Issues other SEO tools miss: semantic drift, cluster cannibalization, content architecture problems, and structural inefficiencies that waste crawl budget.
  • 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

Unlimited crawls policy

"Unlimited crawls" means you can crawl whenever strategy changes, content updates, or traffic shifts require validation. Most users crawl 1–2 times per month, but frequent iteration during active projects is fully supported.
✅ Fair use includes:
  • Weekly crawls during remediation projects
  • Before/after testing to measure structural fixes
  • Cluster expansion validation after new content
  • Internal linking optimization cycles
  • Comparing strategic pivots or topic expansions
  • Re-crawling after major site updates
⚠️ Not fair use:
  • Automated crawling via scripts (use API for this)
  • Reselling crawl access to third parties
  • Crawling competitor sites without authorization
  • Page limits apply to indexable URLs discovered via sitemap or crawl
  • Similarity scoring runs on page-level embeddings
  • Excessive automated usage may require Enterprise pricing
  • Sites requiring authentication may need custom configuration
  • Cancel anytime (no annual lock-in required)
  • Annual billing available (save 15% — 2 months free)

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.

Your card will be charged automatically at the end of your trial period. You can cancel anytime during the trial with no charge. We'll send you reminder emails at 7 days and 1 day before the trial ends.

Yes, you can change plans anytime. Upgrades take effect immediately with prorated billing. Downgrades take effect at your next billing cycle (you keep full access until then).

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.

Start with Free to see if topical drift is impacting your site.

Upgrade to Starter ($49/mo) if:

  • You manage 1 site (blog, small business, personal brand)
  • You need the affected URL lists to start fixing issues
  • You're a freelance SEO consultant

Upgrade to Professional ($149/mo) if:

  • You manage 2-3 sites (multiple brands, subdomain strategy)
  • You have a team that needs shared access
  • You want white-label reports for stakeholders

Upgrade to Agency ($349/mo) if:

  • You manage 5-10+ client sites
  • You need full white-label branding for client deliverables
  • You want to charge clients $199-399/mo for drift monitoring

Yes. If you're not satisfied within the first 30 days, we'll refund your purchase — no questions asked.

For the Audit: We offer 2 revision rounds to ensure you're happy with the deliverable. If you're still not satisfied after revisions, we'll refund 50% of the audit fee.
