DEAD SLOW · CAUTIOUS

5.8 ShipScore / 10

Strongest need — verified SEO spend; weakest control, entirely Google-data dependent.

Condition: Must prove agencies pay for prioritized multi-site refresh briefs — not just decay alerts, which free GSC tools and Toprank already give away.

Part I — The Verdict what the instruments read

01 — The ShipScore breakdown

Control

C4 — decay signals come from Google Search Console/SERP data only

Entry barriers

E3 — Leafpad, SEO Booster PRO, Toprank open-source already ship decay alerts

Need

N7 — EarlySEO $100k and Keytomic $18k verified; multi-site wedge modest

Time-freedom

T8 — automated monitoring plus generated briefs, no per-client labor

Scale

S7 — global publishers and agencies, but SEO-tool buyers are a niche

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 $99/mo (assumed category price), you need 842 subscribers for a $1M/yr pace.

Nearest tracked rivals on that curve:

Keytomic

Part II — The Evidence the receipts, good and bad

03 — Rival scan — corpus tracks 2 similar

MarkupX Brands / EarlySEO	verified MRR $100k · CENTS 6.4 · X-chatter: low (x)	X · quiet
Keytomic	verified MRR $18k (x)

MarkupX Brands / EarlySEO — $100k verified MRR in the same lane; owns the buyer relationship already
Keytomic — $18k verified MRR proves the niche but crowds the mid-market price point
Toprank (open-source GSC traffic-drop fixer) — Free open-source alternative caps what you can charge for alerting

04 — Demand evidence

EarlySEO at $100k verified MRR shows real recurring spend on SEO monitoring
Keytomic at $18k verified MRR confirms a second paying tier exists
Neither tracked product stalls under $2k MRR — category is monetizing
Zero Reddit signal and near-zero complaints on X: pain is treated as solvable, not desperate

05 — Risks

Google Search Console API terms or SERP scraping crackdowns could sever the data feed
Decay alerting is commoditizing fast — multiple 2024-25 launches plus free open-source and Claude skills
Ahrefs/Semrush could ship portfolio decay dashboards as a checkbox feature
AI search shifting traffic patterns may make historical decay baselines less meaningful

06 — Kill switches — what kills this with one decision

Google Search Console API access/quota policy — Lose the per-page impression/click history and the product has nothing to monitor
Google SERP anti-scraping enforcement or rank-data API pricing — Ranking decay signal becomes unaffordable or unobtainable
Ahrefs/Semrush bundling decay detection free into existing plans — Removes the reason for agencies to buy a separate tool

Part III — The Plan if you insist on proceeding

07 — What this scan can't tell you

Cannot tell whether EarlySEO's $100k MRR is growing or flat — trend unknown
No data on what affiliate publishers actually pay per site for refresh workflows
Unknown whether generated refresh briefs are good enough to replace an SEO's judgment

Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-09-11.

08 — The wedge & the next step

Portfolio view for agencies/affiliates running 20+ sites: one ranked queue of refresh briefs across all properties, priced per site — something single-site tools and free GSC scripts cannot assemble.

Cheapest next step: DM 15 affiliate site owners and agency SEOs on X with a manual decay audit of their portfolio; ask for $99/mo preorder before writing code.
