JSON-LD Generator vs TechnicalSEO Schema Markup Generator

JSON-LD Generator is a free web tool that creates structured data markup from fields users fill in, with generated JSON-LD shown in real time. It covers 17 schema types, including Article, Breadcrumb, Course, Event, FAQ, HowTo, Local Business, Organization, Product, Recipe, Review, Video, WebSite and WebPage. Product fields include offers, ratings and reviews; Local Business offers more than 100 subtypes, with examples such as Restaurant, Hotel and Dentist. The tool displays live checks for required fields and produces JSON using JSON.stringify, which the site describes as strictly valid JSON. Users can copy the generated code and open Google’s Rich Results Test, or follow a shortcut to the schema.org Validator. The form state is preserved between visits. A companion address-to-latitude-and-longitude tool is available for Local Business or Organization data. The generator runs on the web and requires JavaScript. Its creator, Patrick Coombe, says the site launched in 2017 as a reference for web developers and SEO practitioners learning about JSON-LD.

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.
