Schema Markup for SEO: Use Structured Data Without Mistakes
A practical Schema Markup guide covering Article, FAQPage, Service and Breadcrumb types, plus hidden and misleading data risks.
Schema markup is a structured way to explain what information a page contains to search engines. It does not automatically improve rankings, but accurate markup can reduce ambiguity when it matches visible content.
Which types are useful?
Use Article for articles, FAQPage when the questions and answers are visible, Service for service pages and BreadcrumbList for page paths. Never add a type that does not describe the page.
Common mistakes
Common problems include hidden FAQs, invented reviews, undisclosed prices and repeating identical Schema across every page. Structured data should represent what a visitor can actually read.
How should you review it?
Test JSON-LD after changes and confirm title, canonical, language and links. Monitor Search Console, but do not treat a rich result as guaranteed.
Read the simple SEO and GEO guide to see how Schema fits the wider system, then request a technical review for a larger site.
Clear answers before you start.
Does Schema guarantee rich results?
No. It helps search engines understand a page, but rich-result display is independent and depends on accurate visible content.
Can FAQs be hidden inside Schema?
No. Questions and answers represented in Schema should be available to visitors on the page.
