TechnicalSEO Schema Markup Generator is a free web tool for creating Schema.org structured data as JSON-LD markup. You choose the Schema.org markup type, then complete the required item properties and any additional properties provided by the generator. The resulting JSON-LD can be copied and pasted into an HTML page. The page links to Google’s Structured Data Testing Tool and Rich Results Test, giving you named destinations for checking the markup. It does not describe automatic publishing, so placing the generated code in a page remains a separate step. TechnicalSEO.com lists this generator among SEO tools covering areas such as crawling, rendering, mobile SEO, international SEO, local SEO, and SERP and ranking. The page also suggests Schema App for an end-to-end schema markup solution. Merkle launched TechnicalSEO.com in April 2015 as a resource for its SEOs, industry members, and clients. The generator runs on the web and has a free plan.
