RankMath Schema Markup: Complete WordPress Setup Guide

Yes — for most content sites, RankMath free covers the essential schema types: Article/BlogPosting, FAQPage, HowTo, Recipe, Event, LocalBusiness, Product (basic), and Person. The key limitations of the free tier are: no custom schema types (no Schema Builder), no JobPosting/Course/Book/SoftwareApplication, and limited WooCommerce product schema depth. If you run a recipe site, local business, or content blog, the free version is sufficient. For e-commerce, job boards, or SaaS products, RankMath Pro is worth the upgrade.

In the post editor, open the RankMath panel in the right sidebar. Click the Schema tab. Click "Add Schema" and select FAQPage from the type list. RankMath will then ask you to add each Q&A pair. Each question and answer you enter becomes a Question entity inside the FAQPage JSON-LD. After saving and publishing, validate the post URL using the Rich Results Test to confirm FAQPage is detected. Note: Google has reduced FAQ dropdown display since 2023, but the schema still provides entity signal value.

This is a common issue with schema-aware themes (Astra, GeneratePress, Divi, Elementor). Go to your theme's settings panel and look for an SEO or Schema section — most have an option to disable theme-generated schema. Disable it there. If your theme doesn't have this option, install a code snippet plugin and add: remove_action('wp_head', [your_theme_schema_function]). You can identify the duplicate schema type by pasting your page URL into SchemaValidator.org and looking for the same @type appearing twice in the output.

The Schema Builder is usually better unless you have very specific requirements. It handles variable mapping automatically (post title, author, image URL all get filled in from WordPress data), validates the schema before saving, and makes fields easy to update without touching code. Write custom JSON-LD directly only when: (1) you need a very specific entity graph structure that the Builder doesn't support well, (2) you need to inject schema on non-WordPress page types, or (3) you're migrating a complex existing schema implementation and want to preserve its exact structure.

The most common reasons: (1) Google's crawler cached an older version of the page — use the URL Inspection tool in GSC to request a fresh crawl. (2) The error is in a schema type that RankMath generates separately from what you validated (e.g. RankMath generates BreadcrumbList separately from Article — validate both). (3) GSC errors can lag by 2–4 weeks after fixes are deployed. (4) A plugin update changed the schema output — always re-validate after plugin updates. Try validating directly from the live URL in SchemaValidator.org rather than copying the code.

RankMath free adds basic Product schema to WooCommerce product pages automatically — including name, price, image, and description pulled from WooCommerce product data. RankMath Pro significantly improves this: it maps product SKU, barcode/GTIN, brand taxonomy, availability based on stock status, and aggregates review ratings from WooCommerce reviews into AggregateRating schema. For a complete WooCommerce product schema, RankMath Pro or Yoast WooCommerce SEO is strongly recommended over the free tier.

Go to RankMath → General Settings → Local SEO. Under the "Social Profiles" section near the bottom of the page, you will see fields for Facebook, Twitter, Instagram, YouTube, LinkedIn, Pinterest, and more. Fill in all the profile URLs where your brand has an active official presence. Each URL you add becomes an entry in the sameAs array in your Organization schema. Adding your Wikipedia article URL (if one exists) and official Wikidata entity URL (e.g. https://www.wikidata.org/wiki/Q12345) are particularly valuable for brand entity strength.

Yes. Go to RankMath → Titles & Meta. If you have custom post types registered, they appear as separate tabs. Each custom post type has its own Schema Markup section where you can set the default schema type and configure its properties. You can set the default to any built-in type (Service, ItemPage, TechArticle, SoftwareApplication) or use the Schema Builder (Pro) to create a completely custom schema template for that post type. This maps each custom field to schema properties automatically.
