SwiftSchema is for website owners, developers, and SEO professionals who need to add or check structured data without building JSON-LD from scratch. Choose from generators for more than 120 Schema.org types, enter details that appear on your page, and create JSON-LD you can copy as data or as a script to add to your site. For a starting point, its AI generator can use a public page URL or pasted page content to suggest schema and produce markup with validation warnings and implementation notes. You can also check existing markup and validate generated JSON-LD before publishing, including with Google’s Rich Results Test and the Schema.org Validator. It can help with tasks such as marking up products, articles, events, local businesses, and services; it’s suited to people who want to prepare and verify structured data, rather than deploy it automatically.
