Rolling Schema vs StructuredValidator

Rolling Schema re-crawls websites, detects content changes, and regenerates validated schema.org structured data. It delivers JSON-LD server-side through a Cloudflare Worker or WordPress plugin so crawlers receive it in the page HTML. Shopify, Wix, Squarespace, and custom sites can use the API to render JSON-LD in their own templates or pipelines. Crawl intervals range from 30 minutes to no longer than one day. The service generates more than 20 schema types, including LocalBusiness, Product, Article, Event, FAQPage, HowTo, Recipe, Organization, Person, JobPosting, and Breadcrumb. Free covers five pages on one domain, 500 credits per month, and no API access. Standard costs €79 a month and includes one domain and 2,500 monthly credits, without API access. Power costs €249 a month, includes API access, 10 domains, and 20,000 monthly credits. Ultimate costs €749 a month and includes unlimited domains, dedicated GPU capacity, white-label reporting, and a custom deployment and SLA. The product targets local and service businesses, publishers, small e-commerce sites, and agencies managing client domains.

StructuredValidator is a free web tool for checking structured markup, with validation focused on JSON-LD. Paste JSON-LD or HTML to see results as you type. It detects Microdata and RDFa in pasted HTML, but validates JSON-LD only. Checks cover JSON syntax, contexts, types, property names, value formats, @id references, and required or recommended properties for supported rich-result features. The URL tool fetches public HTTP or HTTPS pages, extracts JSON-LD from server HTML, and validates it in the browser without rendering JavaScript. Fetches allow four redirects, eight seconds, 2 MB per page, and 12 requests per minute per visitor. A comparison view places two schema implementations side by side to show differences, missing properties, and coverage. Rich-result preview and API access are available. Validation history and preferences stay in browser storage, and the service says it does not retain validation data on its servers. Optional AI suggestions send markup and errors to an AI provider under that provider’s retention policy.
