Rolling Schema
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.
