Schema App
Schema App is an enterprise platform for generating and deploying schema markup — the structured data that helps search engines and AI systems understand a page — across large websites, either page-by-page or templated across similarly-structured page groups. It's sold entirely through a sales conversation, with a minimum 12-month contract and dedicated onboarding, not a self-serve signup.
Schema App's output is built entirely on the open schema.org markup standard and your own site content — the templated deployment tool and its own internal knowledge-graph database are real software to build, not a proprietary data moat like a crawled index.
What you lose building it yourself
- ✕Templated deployment across thousands of similarly-structured pages without hand-editing each one
- ✕An internal knowledge-graph database linking entities across the site and to outside reference sources
- ✕Dedicated onboarding and ongoing support built into the contract
- ✕Markup and entity performance tracking that flags drift as content changes
Why people still pay
For a handful of page types this is a weekend script; what enterprise buyers are actually paying for is reliable deployment across thousands of differently-structured pages, an entity knowledge graph that stays consistent as content changes, and a team that catches markup drift before it costs visibility — ongoing maintenance most in-house teams don't want to own.
BUILD YOUR OWN · WEEKEND SCOPE (BASIC MARKUP), HARDER AT TEMPLATE SCALE
A basic version — schema markup templates for a handful of common types (Article, Product, FAQ, LocalBusiness) inserted into a site's page templates — is a realistic weekend build for an AI coding tool, since schema.org's markup format itself is public and free to use. What's harder to replicate is deploying that reliably across thousands of differently-structured page types without breaking validation, plus an ongoing internal knowledge-graph database and monitoring layer that catches markup drift as content changes.
StackStatic schema markup templates per page type (Article, Product, FAQ, LocalBusiness) written against the public schema.org standard · a CMS templating hook or Google Tag Manager to inject them site-wide · Google's Rich Results Test to check the output validates.
Write a Node.js script that reads a CSV of pages with columns for page type (Article, Product, FAQPage, or LocalBusiness), title, author, datePublished, and price (where applicable), and outputs a JSON-LD script tag for each row using the correct schema.org type and its required properties. Skip and log any row missing a required field for its type instead of generating invalid markup. Write one output HTML snippet per row, named by URL slug, for manual insertion into the site's page template. Cap the run at 500 rows per execution.

Free alternative: Yoast SEO — Yoast SEO's free WordPress tier auto-generates basic schema markup (Article, breadcrumb, review) at no cost; it only works on WordPress, has no templated deployment tool for other platforms, no entity-linking knowledge graph, and no ongoing markup monitoring.
QUESTIONS
Does Schema App offer self-serve pricing or a free trial?
No — every plan is a custom quote with a 12-month minimum contract, a one-time onboarding fee, and a minimum of one paid support hour per month; there's no published price list or self-serve signup.
Is the markup format itself proprietary to Schema App?
No — it outputs standard schema markup built on the public schema.org standard, the same open format any site can implement without Schema App. What's proprietary is the company's own templated deployment tool and internal knowledge-graph database.
Can structured data actually stop an AI system from getting a brand wrong?
Schema App markets its entity linking as reducing AI 'hallucinations' about a brand — that's a vendor claim about how outside AI systems interpret markup, not something independently measurable. No schema markup can guarantee how a third-party AI model describes a brand.
