Schema markup is one of those terms that gets thrown around in SEO conversations without much explanation, and business owners often nod along without really knowing what it means or whether it’s something they need to worry about. The short version is that it’s a way of labelling the content on your website so search engines can understand it properly, rather than having to guess. It’s not glamorous, and on its own it won’t turn a struggling website around, but it’s one of those foundational things worth getting right.
What schema markup actually is
When Google crawls a webpage, it reads the text much like a person would, but it doesn’t automatically know that “£85” is a price, that “4.9 stars” is a review rating, or that “Mon–Fri, 8am–6pm” refers to opening hours. Schema markup is a bit of structured code added to the page — invisible to visitors — that spells these things out explicitly. It tells Google: this is a business name, this is an address, this is a phone number, this is a review score, and so on.
It’s technically known as structured data, and schema.org is the shared vocabulary most search engines agree on for writing it. You don’t need to understand the code itself to benefit from it — most website platforms can add the basics automatically or through a plugin — but it helps to know what it’s doing and why it’s there.
Why it matters more for local businesses than you’d think
For a local business, a lot of what makes you findable and trustworthy is exactly the kind of information schema markup is designed to describe: your address, your service area, your opening hours, your reviews, the specific services you offer. Getting this right doesn’t guarantee better rankings on its own, but it does make it far easier for Google to display your business accurately and to pull out the extra detail that shows up in search results — star ratings under a listing, opening hours in the knowledge panel, or a direct answer to a question someone typed in.
It also feeds into how AI-generated search results work. We wrote recently about what Google’s AI Overviews mean for small businesses, and one of the quieter points in that shift is that these AI summaries lean heavily on structured, unambiguous information rather than having to interpret loosely written page content. A site with clean schema markup is simply easier for both traditional search and AI-driven results to use correctly.
The types worth prioritising
There’s a long list of schema types available, and most small businesses don’t need anywhere near all of them. In our experience, a handful cover the vast majority of the value.
LocalBusiness schema is the obvious starting point — it covers your business name, address, phone number, opening hours and the type of business you are. This should broadly match what’s set up on your Google Business Profile, which we’ve written about separately when it comes to avoiding the mistakes that cost you enquiries there too. Consistency between the two matters; Google cross-references this kind of information, and mismatched details in different places can undermine trust rather than build it.
Review schema, where it’s genuinely earned and accurate, can help star ratings display in search results. Service schema helps if you offer several distinct services and want each one clearly identified rather than lumped together on one page. FAQ schema can be useful on pages where you’re genuinely answering common questions, though it’s worth noting Google has scaled back how often it displays FAQ rich results, so treat it as a nice-to-have rather than the main event. Breadcrumb schema, which describes the navigation path to a page, is a small thing that tends to tidy up how a URL is displayed in results.
A quick example of why this matters
Picture a general builder with a decent website and genuinely good reviews scattered across Google and a couple of trade directories. Without schema markup, none of that context is explicit to a search engine — it has to infer the business type, the service area and the credibility signals from ordinary page text, which it may or may not do accurately. Add the right LocalBusiness and Review markup, and the same information becomes unambiguous: this is a builder, based here, covering these areas, rated this well by this many people. Nothing about the business has changed, but it’s now much easier for Google to represent it correctly, and easier for it to be surfaced for the right searches rather than a vaguely related one.
Common mistakes we see
The most frequent issue isn’t missing schema at all — it’s schema that’s gone stale. A business moves premises, changes its phone number, or drops a service line, and the markup in the code never gets updated to match, even though the visible page content has been changed. Search engines can pick up on this kind of inconsistency, and at best it’s ignored; at worst it creates confusion about which version of the information is accurate.
The other common mistake is over-marking content that isn’t really there — describing reviews that don’t exist on the page, or ratings that aren’t genuinely displayed to visitors. Google’s guidelines are explicit that structured data should reflect visible, accurate content, not be used to game how a listing appears. It’s not worth the risk, and it tends to get caught anyway.
How to check if yours is set up correctly
Google’s Rich Results Test is a free tool that lets you paste in a URL and see exactly what structured data it can read from the page, along with any errors or warnings. It’s worth running your homepage and a couple of key service pages through it, since coverage often varies a lot from page to page depending on how and when each one was built. If nothing shows up at all, or the tool flags errors on information you know to be correct, that’s usually a sign it’s worth having a proper look at.
Where this fits into the bigger picture
Schema markup is a genuinely useful piece of technical housekeeping, but it’s exactly that — housekeeping. It works best alongside a website that’s fast, well-structured and easy to use, and it’s one of the areas we check as part of onsite technical SEO work, alongside site speed, crawlability and the more foundational technical basics.
