Schema Markup Explained: What It Is and Why It Helps

Schema markup (structured data) is one of the more technical-sounding parts of SEO, but the concept behind it is simple: it's a way of explaining your content to search engines in a language they parse with certainty.

What It Actually Does

It helps search engines understand specific facts about your page — that a page is a FAQ, that a business has certain hours, that a page is a specific service — rather than inferring it.

It can enable rich results in search (star ratings, FAQ dropdowns, breadcrumb trails) that make a listing stand out.

Common Schema Types Worth Using

LocalBusiness schema, which communicates your business's core information directly to search engines and local search features.

FAQPage schema, which can surface expandable questions directly in search results.

BreadcrumbList schema, which helps both users and search engines understand where a page sits in your site's structure.

What It Won't Do

Schema markup doesn't directly boost rankings on its own — it improves how your content is understood and displayed, which indirectly supports performance.

Incorrect or misleading schema (marking up content that isn't actually on the page) can trigger manual penalties from Google.
