Structured Data & Schema Markup: The Complete Guide

What schema markup is, which types every business site needs, how to implement and validate it, and the mistakes that waste the effort.

Schema markup is vocabulary you add to your pages so machines know what your content is — a business, a service, an article, an FAQ — not just what it says.

The types every business site needs

  • Organization / LocalBusiness — who you are, where, how to contact you
  • Service — one per service page, with clear descriptions
  • FAQ — the questions you actually get asked
  • Article — on every blog post, with author and dates
  • Breadcrumb — site structure made explicit

Implement and validate

JSON-LD in the page head is the standard format. Mark up only what is visibly on the page, validate with Google's Rich Results Test, and monitor the Enhancements reports in Search Console monthly.

The classic mistakes

Marking up invisible content, fake review stars, orphaned schema that references nothing, and stale data. Structured data is a trust system — treat accuracy as non-negotiable. Webnet ships complete, validated schema on every page we build.
