Schema Markup Generator
Structured DataFree JSON-LD structured data generator by Merkle's team
Overview
Schema Markup Generator by Merkle is a straightforward, no-frills tool for creating JSON-LD structured data markup. Built by the team at Technical SEO, this free generator focuses on the most common schema types that actually drive rich results in search engines. Unlike complex enterprise tools or WordPress plugins with dozens of features, this generator does one thing well: produces clean, valid JSON-LD markup for essential schema types.
The tool emerged from Merkle's internal need for a reliable way to generate structured data markup quickly. Rather than wrestling with complex schema documentation or building markup from scratch, their team created a form-based interface that guides users through the process. They made it publicly available in 2019, and it's remained a go-to resource for SEOs who need quick, reliable schema generation.
What sets this apart from other schema tools is its focus on markup that actually matters for SEO. While platforms like Schema Pro offer dozens of schema types, Merkle's generator concentrates on FAQ, HowTo, Product, LocalBusiness, and other schemas that frequently trigger rich results. This targeted approach means less feature bloat and faster markup generation.
