Schema Markup Audit & Generator Tool Build

I built the Schema Markup Audit & Generator as a public SEO tool for site owners who know structured data matters but do not want to become developers just to add JSON-LD.

Most schema tools stop at validation. This one audits a URL, explains what structured data is present or missing, and generates ready-to-paste markup with CMS-specific implementation guidance.

Existing structured data on the submitted URL

Missing schema opportunities based on page type and business context

Plain-English explanations of why each schema type matters

Ready-to-paste JSON-LD output

CMS-specific implementation steps

Usage tier logic for anonymous, email, and paid users

The front end runs in Astro on bree-sharp.com. A Cloudflare Worker handles the API layer, rate limiting, URL analysis, and calls to the Claude API for recommendation logic.

The user flow is deliberately narrow: paste a URL, choose a CMS, receive a schema audit, then copy the generated JSON-LD and implementation notes. The goal is to make the next action obvious instead of leaving the user with a validation report they still have to translate.

I also built a usage ladder instead of a hard paywall. Anonymous users get a small number of analyses, email users get more, and heavy users can buy a block of credits through Stripe. That keeps the tool useful as a lead magnet while giving it a way to cover API costs.

The tool works as a public utility, a conversion asset, and a portfolio artifact. Visitors can use it immediately, understand what it does, and see the engineering judgment behind the SEO recommendations.

It also connects naturally with the rest of the tool suite: schema explains page meaning, while robots.txt, sitemap validation, and indexability checks cover discovery and crawl eligibility.
