If you have ever run a website audit, you may have seen a warning about "missing structured data" or "no schema markup detected." It sounds technical, and most business owners skip past it assuming it is something only developers need to worry about.
It is worth understanding, though, because it is one of those quiet improvements that can meaningfully affect how often your business gets found, and increasingly, whether AI tools like ChatGPT and Google AI recommend you at all.
What structured data actually is
Every website is written in HTML, the code that tells your browser what to display on screen. A heading, a paragraph, an image, a button. That code describes how things look.
Structured data is a separate layer of information added to the same page that describes what things mean. Not just "this is a heading" but "this heading is the name of a local business." Not just "this is a number" but "this number is a price."
Think of it like this. A human reading your website can figure out from context that you run a physiotherapy clinic, that your opening hours are Monday to Friday 9am to 6pm, and that an appointment costs from $80. But Google's search crawler reads millions of pages per second. Structured data gives it a shortcut, a direct, unambiguous label on every important piece of information so it does not have to guess.
Why it matters more than it used to
Structured data has always helped with search rankings and rich snippets, those enhanced search results that show your star ratings, opening hours, or pricing directly in Google's results page, before someone even clicks through to your site.
But it matters even more now because of how AI search works. When someone asks ChatGPT or Google's AI overview to recommend a physiotherapy clinic in their area, those tools need to understand what your page is about, what you offer, where you are located, and how much you charge. Without structured data, they are making educated guesses from your body copy. With structured data, you are telling them directly.
Pages without structured data are more likely to be overlooked when AI tools are assembling recommendations. Pages with it are more likely to be surfaced confidently and accurately.
What types of structured data matter for small businesses
The most useful types depend on what your business does:
- Local business markup: your name, address, phone number, opening hours, and business category. Useful for almost any business with a physical location or local service area.
- Service markup: what services you offer and what they cost. Useful for consultants, clinics, tradespeople, and professional services businesses.
- Product markup: product names, prices, availability, and reviews. Useful for e-commerce and product-based businesses.
- FAQ markup: if your page includes questions and answers, this can get those answers displayed directly in search results.
- Review markup: if you have customer reviews or ratings on your page, this can surface your star rating in search results.
How to get structured data added to your page
If you use WordPress, there are plugins that add structured data automatically, Yoast SEO and Rank Math both handle the most common types without you needing to write any code. If you use Squarespace or Wix, some structured data is added automatically, though you may need to check that it is configured correctly for your business type.
If your site is custom-built, this is a task for your developer. The implementation is not complex, it is typically a block of code added to the head of your page, but it does need to be done correctly to pass Google's validation tests.
If you are not sure whether your page already has structured data, a free scan will check for it and tell you exactly what is missing and what type to add.
Structured data is one of those behind-the-scenes improvements that does not change how your page looks but can significantly change how often it gets found and recommended. It is also one of the things most small business websites are missing.
