Kerbrank

About this app

Kerbrank helps UK businesses and agencies see where they rank on Google Maps street by street. It runs the same search from a grid of points around each business, checks whether ChatGPT recommends the business, compares nearby competitors and produces a short weekly fix list. Every plan includes weekly automatic rescans, local search demand, competitor insights and shareable reports. Pro and agency plans support branded client reports. Kerbrank is built for UK postcodes and businesses, priced in pounds, and starts with a 14-day free trial with no card required.

Key features

1Grid-based Google Maps rank tracking from up to 225 points, with sea points excluded so coastal businesses get a fair average.
2ChatGPT visibility checks — asks the questions customers ask and reports how often you're named versus competitors.
3Weekly automatic rescans with a plain-English fix list; tick a job off and the next scan verifies the problem is gone.
4UK-first positioning: GBP pricing from £29/month, postcode-aware, with branded client reports on Pro and Agency plans.

Scout Review

Written by AI from measured evidence, scored out of 100.

Kerbrank is a UK-focused local rank tracker that does grid-based Google Maps tracking, ChatGPT recommendation checks and a weekly fix list, priced from £29/month with a 14-day no-card trial. The build quality is genuinely above average: Lighthouse mobile 97/100 with zero layout shift, a perfect desktop score, and a 12/12 security header probe. The homepage sells with a live heatmap rather than a stock illustration, and the free no-signup rank check is a smart acquisition hook. Documentation is real — eight guides covering setup through billing — and the UK positioning (pounds, postcodes, sea-point exclusion) is consistent rather than decorative. The gaps are the usual early-stage ones: no SOC 2 or pen-test paperwork, no accessibility statement, English-only, and a domain registered in 2026. Against BrightLocal and Local Falcon, Kerbrank is narrower but sharper, and the ChatGPT visibility check is a genuine differentiator for now. It's a competent, well-built tool that hasn't yet proven anyone will pay for it at scale.

Measure by measure

Usability

Free 25-spot rank check with no sign-up is a strong try-before-register hook. 14-day trial needs no card. Eight guides (~36 min) cover setup to billing, and support promises a human reply in two working days.

Design

Clean, confident UK-branded UI. The live 9x9 heatmap demo with real rank numbers does more selling than any hero illustration. Pricing cards are dense but readable, with per-business maths shown.

Speed

Lighthouse mobile 97/100 (LCP 2.2s, CLS 0, TBT 15ms) and desktop 100/100. A zero CLS with an interactive grid demo on the homepage is genuinely well-built front-end work.

Security

Full header set verified: HSTS, CSP, frame protection, Referrer-Policy, Permissions-Policy, plus SPF and DMARC — 12/12 on the probe. Stripe handles card payments. No published SOC 2 or pen-test claim.

Accessibility

Lighthouse accessibility 100/100 with one residual failing audit on accessible names. Responsive layout confirmed by the mobile run. No WCAG statement or multi-language support published.

Growth

Improvement areas

No published security page, SOC 2, ISO 27001 or pen-test documentation — a gap for agency procurement.
No accessibility statement or WCAG conformance claim, and one residual failing audit on accessible names.
English-only with no multi-language support, limiting use outside the UK despite the postcode focus.
Very early stage (domain registered 2026) with no visible third-party reviews or case studies to validate outcomes.

Design & Usability

Kerbrank's design does the one thing most local SEO tools fail at: it shows the product instead of describing it. The hero is a live 9x9 heatmap for a fictional Leeds plumber, with real rank numbers, colour bands and a 'point E5 · rank 1' callout — you understand grid-based rank tracking in about four seconds. The UK positioning is threaded through everything: 'PRICED IN POUNDS', 'MADE IN THE UK, FOR UK SEARCHES', and a genuinely clever detail about excluding sea points so coastal businesses get a fair average. Usability follows the same pattern. There's a free rank check on the homepage — one search, 25 spots, no sign-up — which is the right hook for a category where buyers are sceptical. The 14-day trial needs no card. The guides hub lists eight short reads (~36 minutes total) covering setup, reading the map, the job list, competitor comparison, ChatGPT visibility, report sharing and billing, which is more documentation than most tools at this price ship. Support is an instant-answers assistant plus a human email reply within two working days. The pricing page is dense — four tiers, per-business maths, a plan-finder widget — but the numbers are honest and the '£19.67 per business a month when full' framing is refreshingly direct.

Speed & Security

Speed is where Kerbrank quietly embarrasses its category. Lighthouse mobile performance is 97/100 with an LCP of 2.2s, a CLS of exactly 0 and a TBT of 15ms; desktop scores a perfect 100/100. A zero cumulative layout shift on a page carrying an interactive grid demo is not an accident — it's disciplined front-end work, and it means the marketing site won't be the reason someone bounces. Security is similarly tidy. The HTTP probe came back 12/12: HTTPS enforced, HSTS, a Content-Security-Policy, frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy all present, with SPF and DMARC published on the domain. Card payments run through Stripe, which is the correct call for a small team. What's missing is the paperwork larger buyers ask for — no SOC 2, no ISO 27001, no published pen-test or bug-bounty programme. For a £29–£259/month tool aimed at UK SMEs and small agencies, that's a normal gap at this stage rather than a red flag, but an agency putting client data through it may want a security page before signing.

Accessibility & Growth

Accessibility is strong on the automated side: Lighthouse scores 100/100, and the mobile run confirms the layout is responsive. One failing audit remains — elements with visible text labels that don't have matching accessible names — which is the kind of thing a screen-reader user notices and a sighted developer never does. There's no accessibility statement or WCAG conformance claim anywhere in the fetched content, and the product is English-only, so anyone outside the UK gets nothing. On growth, the idea holds up better than most in this space. Kerbrank names a real, demonstrable problem — Google Maps results change depending on where the searcher is standing, so a single rank number hides the fact that you're invisible two miles away — and illustrates it with a Bramley vs Headingley comparison. The wedge is specific: UK postcodes, GBP pricing, sea-point exclusion, ChatGPT recommendation checks and a weekly fix list that gets re-verified on the next scan. Against BrightLocal and Local Falcon, that's a narrower but sharper position. The limit is that grid rank tracking is a well-served category and the ChatGPT check is a feature incumbents can copy. The domain was registered in 2026, so this is very early — the idea has room, the execution has to earn it.

Conclusion

If you run a UK service business or a small agency with local clients, Kerbrank is worth the free rank check alone — it takes a minute and shows you something a single Google search never will. The 14-day trial needs no card, so the downside is your time. The honest caveats: this is a young product with no published compliance paperwork, no accessibility statement and no multi-language support, and the grid-tracking category is crowded. If you need SOC 2 for procurement or you're outside the UK, look elsewhere for now. If you're a Leeds plumber or a Bristol agency wondering why a client ranks at their own desk but nowhere else, this is built for exactly that question, and it answers it cleanly.

Suggestions for improvement

Publish a security page with your data-handling practices, sub-processors and any pen-test or SOC 2 roadmap — agencies will ask.
Add an accessibility statement and fix the remaining accessible-name audit; a 100/100 Lighthouse score with a known failing audit is an easy win.
Show a real customer result on the homepage — a before/after average position with dates would beat any feature list.
Consider a lightweight public API or CSV export for agencies who want to pull Kerbrank data into their own reporting stack.
