Pre-launch site-migration risk auditor that diffs crawl snapshots, redirect maps, and server logs to flag ranking-loss risks before replatforms go live; sold to SEO agencies and enterprise marketing teams. · SEO Technical Audit
Condition: Three agencies must pre-pay for a migration audit before you build log ingestion.
Part I — The Verdict what the instruments read
01 — The ShipScore breakdown
Control
6
C6 — own crawler and direct agency sales; GSC/log APIs swappable-ish
Entry barriers

E4 — Screaming Frog named for pre-migration crawls; no tracked leader growing
Need

N6 — only adjacent $6k/$3k MRR tools; zero Reddit/X signal on concept
Time-freedom

T7 — productized diffing, but log ingestion and enterprise onboarding stay manual
Scale

S7 — global agencies and enterprise marketing teams, replatforms happen everywhere
What the five commandments measure
C — Control
Do you own the customer, or does a gatekeeper stand between you and revenue?
E — Entry
How hard is this to copy once it works? A rival's existence isn't the question — the durability of their advantage is.
N — Need
Is demand proven with money rather than vibes?
T — Time
Can income detach from your hours, or did you buy yourself a job?
S — Scale
How far does it reach without linear cost?
Scored on the evidence below, against CENTS as we've adapted it plus a Buffett-style moat reading of every rival — the same referee for every idea, including the ones we generate ourselves. The verdict follows the arithmetic: we never relabel a score to make it read better, and the weakest commandment is always named. The exact rubric stays in-house so the scale can't be written for.
02 — The pace test — $1M/yr
At $199/mo (assumed category price), you need 419 subscribers for a $1M/yr pace.
Screaming Frog — Evidence shows it's the default tip for pre-migration crawls and redirect maps, cheaply.
Xagio.com - AI SEO — Verified $6k MRR proves SEO tooling spend, and can bolt on migration checks.
Advanced GSC MCP — $3k verified MRR; already wired into Search Console data you'd need.
04 — Demand evidence
Two tracked SEO tools carry verified MRR ($6k Xagio, $3k Advanced GSC MCP) — category spend is real.
Zero Reddit signals and essentially zero X chatter for migration-risk auditing as a product.
X evidence shows practitioners solving this today with Screaming Frog, i.e. budget exists but flows elsewhere.
No funded companies tracked in or near the space — no validation and no proven pull.
05 — Risks
Migration audits are episodic, not monthly — churn after each replatform launch.
Screaming Frog plus a spreadsheet covers 80% of the job for £199/year.
Enterprise log-file access is a security and procurement slog.
Ranking-loss attribution is unprovable; buyers may dispute your value after launch.
06 — Kill switches — what kills this with one decision
Google Search Console API terms or quota changes — Removes the performance-delta data that proves your risk flags mattered.
Screaming Frog shipping a native crawl-diff/migration report — Wipes the wedge at a price point you cannot match.
Part III — The Plan if you insist on proceeding
07 — What this scan can't tell you
Cannot tell whether agencies buy migration tooling per-seat or bill it as a service.
No data on actual replatform volume or typical migration audit budgets.
Unknown how many enterprises will grant server-log access to a third-party SaaS.
Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-08-23.
08 — The wedge & the next step
Sell it as per-migration insurance to agencies — a fixed-fee pre-launch pass/fail report with a redirect-gap diff they can hand to the client's dev team.
Cheapest next step: DM 15 technical SEO leads at agencies offering a free manual migration audit on their next replatform; count how many hand over staging access.
