What is Schema Markup?

Schema Markup uses a vocabulary defined at Schema.org - a collaborative project between Google, Bing, Yahoo, and Yandex. You add structured data to your HTML (typically as JSON-LD in a <script> tag) that explicitly tells search engines what your content means. For example, instead of a search engine guessing that "4.5" on a page is a rating, Schema Markup explicitly says: "This is a rating of 4.5 out of 5 for a local business."

• LocalBusiness - Business name, address, phone, hours, reviews • FAQPage - Question and answer pairs that can appear as expandable results • Article / BlogPosting - Author, publish date, headline for news and blog content • Product - Price, availability, reviews for e-commerce • HowTo - Step-by-step instructions with images • BreadcrumbList - Navigation breadcrumbs shown in search results • Organization - Company info, logo, social profiles • WebSite - Sitelinks search box and site name • Review / AggregateRating - Star ratings in search results • Event - Event dates, location, and ticket information

Google recommends JSON-LD (JavaScript Object Notation for Linked Data) as the preferred format for structured data. JSON-LD is embedded in a <script> tag in the page head and does not require modifying your HTML body. Advantages of JSON-LD: • Easy to implement and maintain • Does not affect page rendering or layout • Can be dynamically generated • Cleanly separated from HTML markup • Supported by all major search engines

Rich results (formerly "rich snippets") are enhanced search listings that include additional information like star ratings, prices, FAQ accordions, or images. Not all Schema types trigger rich results - Google decides which types to display based on content quality and compliance with their guidelines. Common rich result types: • Review stars and ratings • FAQ expandable sections • How-to steps with images • Product price and availability • Recipe cards with cooking time • Event dates and ticket links

1. Identify which Schema types are relevant to your content 2. Write JSON-LD structured data following Schema.org specifications 3. Add the JSON-LD script to your page's HTML head 4. Test using Google's Rich Results Test tool 5. Monitor in Google Search Console under the Enhancements report 6. Fix any errors or warnings flagged by validation tools Platforms like PixlSEO can auto-generate Schema Markup for common types like LocalBusiness, FAQ, and Article.
