Static calculator website pilot
Prove one reusable calculator before multiplying pages.
SignalMend builds one fast, cacheable calculator shell and one accepted calculator module first—so layout, math, metadata, and deployment are verified before category expansion.
$49 diagnosis · $149 first repair pilot · starts after funding and access
Good first-pilot signals
- A calculator library needs a reusable page system, not copied one-off files.
- WordPress or a database adds runtime work to otherwise static pages.
- Inputs work visually, but edge cases and invalid states are not tested.
- Metadata, canonical URLs, or deployment steps drift between calculators.
Included
- One reusable responsive page template
- One working calculator with agreed test cases
- Semantic HTML, plain CSS, and vanilla JavaScript
- Canonical, Open Graph, JSON-LD, robots, and sitemap foundation
- Git setup, static deployment, and a 3–5 minute walkthrough
Not included
- Bulk calculator, category, or search expansion before pilot acceptance
- Accounts, database, CMS, or payment functionality
- Legal, financial, or medical accuracy certification
- Traffic, ranking, conversion, or revenue guarantees
- Production changes before scope, funding, and authorized access
Acceptance
A repair is complete only when the evidence is repeatable.
- 01The agreed calculator returns correct results for valid, zero, and invalid test inputs.
- 02The template remains usable with keyboard controls and responsive at mobile and desktop widths.
- 03The built page contains the agreed canonical, social, structured-data, robots, and sitemap metadata.
- 04A clean Git checkout builds and deploys using the documented static-hosting steps.
Relevant evidence
Live break-even calculator shell
A self-initiated static implementation demonstrates responsive semantic HTML, plain CSS, local vanilla-JavaScript math, JSON-LD and Open Graph metadata, a pinned Chart.js asset, robots, sitemap, and zero stored inputs. It is evidence of implementation—not invented client work or traffic results.
