What is Schema Markup?

Schema markup using JSON-LD format provides search engines and AI crawlers with machine-readable context about your page content. Common schema types for SaaS websites include: Organization (homepage), WebSite with SearchAction (homepage), BlogPosting with Person author (blog posts), FAQPage (FAQ sections), BreadcrumbList (navigation), SoftwareApplication (product pages), and HowTo (tutorials). Google's Rich Results Test should be used for validation rather than curl, because many CMS systems inject schema via client-side JavaScript. Schema markup directly improves visibility in Google's featured snippets and AI Overviews. For SaaS companies, proper SoftwareApplication schema can trigger software-specific rich results showing pricing, ratings, and features directly in search results.
