Plumbing Schema Pack — Founding MVP
Plumbing Schema Pack — Founding MVP
A plumbing-specific structured data decision guide and JSON-LD template kit. Built for plumbing businesses, web developers, marketing agencies, and local SEO providers who want a clear, plumbing-specific framework instead of guessing.
This is a decision guide first and a template kit second. It helps you understand what schema belongs on a plumbing website, why it belongs there, what visible page evidence must support it, and how to validate the result before publishing.
Single-site license. Instant digital delivery.

17 files. One Clear Framework.
00 — README: Start Here — What this pack is, what it is not, and the correct reading order so you don't waste time on the wrong file first.
00b — Quick Reference Card — One-page schema type reference. Which type belongs on which page, the PlumbingBusiness type hierarchy, and required vs. recommended properties at a glance.
The decision layer
01 — Plumbing Schema Decision Guide — The core document. Which schema types belong on which plumbing page types, why they belong there, and what visible page evidence must support every field before you implement anything.
05 — FAQPage Eligibility Guide and Template — FAQPage schema is widely misused. This file tells you where you've earned it, where you haven't, and the actual eligibility criteria — updated for Google's May 2026 full deprecation of FAQ rich results.
06 — Review and Rating Safety Notes — AggregateRating has strict rules Google enforces. This file tells you exactly what must be in place before you implement it — and why most plumbing businesses should skip it entirely.
The templates
02 — Homepage JSON-LD Template — Ready-to-fill PlumbingBusiness entity schema with inline field guidance and visible evidence requirements built in.
03 — Service Page JSON-LD Template — For individual service pages — drain cleaning, water heater installation, emergency plumbing, sewer line repair, and more — with real service-specific examples included.
04 — Service Area Page JSON-LD Template — For city and county landing pages, with strong warnings against thin doorway pages and clear content requirements before schema belongs on the page at all.
07 — BreadcrumbList Guidance and Template — Navigation hierarchy schema with real-world plumbing site structure examples and implementation order.
The execution layer
08 — Visible Page Evidence Checklist — Schema must be backed by real on-page content. This checklist walks every field and confirms your page actually supports what you're claiming.
09 — Plugin and Theme Conflict Warning Sheet — The most common reason schema breaks without an error message. Covers ServiceTitan, Jobber, Housecall Pro, and common WordPress plugin conflict patterns. Read this before you publish anything.
10 — Validation Workflow — Step-by-step process for testing your implementation in Google's Rich Results Test and Schema Markup Validator before and after the page goes live.
11 — Stop and Hire Help Rules — Clear criteria for when this stops being a DIY situation and what to tell a developer when you hand it off.
Handoff and compliance
12 — Web Developer Handoff Notes — If you're passing this to a developer, this document tells them exactly what to implement, where, and how to confirm it's done correctly.
13 — License and Usage Notes — Single-site license terms. What you can do with these files, what you can't, and how commercial licensing works.
14 — Implementation Tracking Sheet — Page-by-page status tracker covering service pages, service area pages, and BreadcrumbList implementation.
15 — Changelog and V1 Roadmap — What changes between Founding MVP and V1, what founding customers receive automatically, and when to expect the update.
Built for four types of people
-
Plumbing Businesses
You want schema done right without paying a developer to guess. This pack gives you the framework to do it yourself — or hand it off with confidence. -
Web Developers
You build plumbing sites but schema isn't your specialty. This pack tells you exactly what to implement, on which pages, and what to verify before you call it done. -
Marketing Agencies
You manage local SEO for plumbing clients. This pack standardizes your schema process across every client site — no more reinventing the wheel per engagement. -
Local SEO Providers
You know schema matters but plumbing-specific implementation guidance doesn't exist anywhere else. Until now.
"Why not just ask ChatGPT?"
You can. Here's what you'll get: schema that looks correct, probably validates, and may or may not actually match your page.
ChatGPT doesn't know what's on your page. It doesn't know whether your service area page has a visible address or just a city name in the headline. It doesn't know whether your FAQPage actually has questions or just an accordion widget that Google can't read. It doesn't know your theme is outputting a duplicate schema type that will cause your whole block to fail silently.
It generates plausible schema. That's not the same as correct schema for your specific situation.
This pack teaches you to make that distinction yourself — so you stop shipping schema that looks right but doesn't perform.
This is the founding price. Here's what that means.
V1 will expand this Roofing pack with additional page templates — About, Contact, and BlogPosting examples — plus stronger service-area guidance, expanded schema type coverage for roofing-specific scenarios, and multi-location notes. Founding customers get the V1 Roofing update at no additional cost. No coupon codes. No request required.
Common Questions
What format are the files in?
All 17 files are delivered as Markdown (.md) files. They open cleanly in any text editor, Notion, Obsidian, VS Code, or any notes app. You don't need any special software.
Is this for WordPress specifically?
The JSON-LD templates are platform-agnostic. They work with WordPress, Squarespace, Wix, Webflow, or any platform that lets you add a script block to the page head. The Plugin and Theme Conflict Warning Sheet does include WordPress-specific notes because that's where most conflicts occur.
What if I have multiple plumbling sites?
The Founding MVP license covers one site. If you're managing multiple sites or client accounts, reach out before purchasing — commercial licensing is available separately.
What's the refund policy?
Because this is an instant-delivery digital product, all sales are final. If something in the pack doesn't work as described, contact us and we'll make it right.
I'm not a technical person. Can I still use this?
The Decision Guide and the Visible Page Evidence Checklist are written for non-technical users. The JSON-LD templates do require pasting code into your site — if that's a hard stop, the Web Developer Handoff Notes are written so you can hand everything off without losing the thread.
