What is schema markup and why does it matter?

Schema markup is structured data added to your website that tells search engines – and increasingly AI tools – not just what your pages say, but what they mean.

Without schema markup, a search engine reading your website has to infer meaning from the text and structure of the page. With schema markup, you are explicitly telling it: this is a business, this is a review, this is a product, this is a frequently asked question, this is an event. That clarity allows search engines to represent your business more richly and accurately in search results – through star ratings, FAQ dropdowns, event listings, product prices, and other enhanced features that take up more space on the results page and attract significantly higher click-through rates.

Schema markup also matters increasingly for AI-generated search responses. AI tools use structured data to identify authoritative, well-organised sources of information when generating their responses. Websites with clear, comprehensive schema are more likely to be referenced accurately in AI-generated answers than those without it.

The schema types most relevant to small businesses are Organisation schema – which establishes your business as a verified entity with consistent contact details, logo, and social profiles – FAQ schema for question and answer content, Review and Aggregate Rating schema for displaying star ratings in search results, and Service or Product schema depending on what you sell.

Most good WordPress SEO plugins – including Rank Math and Yoast – handle the most common schema types without requiring you to write code manually. The important thing is to make sure they are configured correctly and that the information they output is accurate and consistent with what appears elsewhere online.
