Google Rich Results Test vs TechnicalSEO Schema Markup Generator

Google Rich Results Test is a free web tool for checking structured data and identifying rich result types a page may enable in Google Search. You can enter a full URL or paste code, then rerun the test. It accepts JSON-LD, RDFa, and Microdata, and can render JavaScript. Testing uses either a smartphone or desktop user agent, with smartphone selected by default. Results report structured-data errors and suggestions, identify detected result types, and show relevant rendered source code in an explorer. Some types receive previews for possible Search or Google Assistant appearances, including desktop and mobile layouts where available. Results can be shared through browser links without permissions; test state and code are saved, while shared links and bookmarked history remain available for approximately 90 days. Anonymous testing needs no Search Console permission, but pages and resources must be reachable publicly. A tunnel can expose local or firewalled pages. Preview output is not guaranteed to match the eventual Search result.

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.
