What is Schema Markup?

Schema markup sounds like a technical rabbit hole, but it's simpler than it looks once you know what it does. This guide explains what it is, why it's worth bothering with for a trades or service business, and which types still earn their place in 2026.

What is Schema Markup?

Schema markup is a small piece of code you add to your website. It helps search engines understand your content, not just read the words on the page but actually grasp what they mean.

Without it, Google has to guess what your business does from your text alone. With it, you're telling Google straight out: "This is a local business. These are our services. These are our opening hours. These are our reviews."

Think of it as a label stitched into your site. Your visitors never see it, but search engine crawlers read it constantly.

Schema is written in a format called JSON-LD (JavaScript Object Notation for Linked Data), which is the format Google recommends. It sits in the <head> of your pages and never shows up on screen.

Here's what a basic version looks like in your code:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "LocalBusiness",
  "name": "Your Business Name",
  "telephone": "01234 567890",
  "address": {
    "@type": "PostalAddress",
    "addressLocality": "Nottingham",
    "addressCountry": "GB"
  }
}
</script>

How Schema Works

From the moment you add it to the moment it changes your search listing, schema goes through four stages.

From Code to Search Result
1 You add the code JSON-LD goes on your pages, describing your business, services, or content.
2 Google reads it When Google crawls your site, it reads the schema and understands your pages more precisely than from text alone.
3 Data is processed Google stores the structured data and uses it to categorise your business and match it to relevant searches.
4 Your listing improves Your result can show extra detail like star ratings, opening hours, or service areas, known as rich results.

Types of Schema That Matter for Trades Businesses

There are hundreds of schema types, but only a handful actually do anything for a UK trades or service business. These are the ones worth your time.

The Schema Types Worth Adding
LocalBusiness Essential
Tells Google your business name, address, phone number, opening hours, and service area. If you do nothing else, do this. Add to: your homepage
Service High value
Defines each service you offer, such as roofing, landscaping, or electrical work, with descriptions and areas covered. Add to: each service page
Review / Rating Trust builder
Pulls your star rating into search as gold stars, which has a real effect on how many people click. Add to: pages with reviews
BreadcrumbList Structure
Helps Google read your site structure and can show a breadcrumb trail under your URL, making the listing cleaner. Add to: inner pages
Article / BlogPosting Content
Adds context to your blog posts, including the published date, author, and topic, helping them surface in content searches. Add to: blog posts
FAQPage See note below
Still valid, but no longer shows as a rich result. Harmless to keep if you have genuine FAQ content. Add to: pages with real FAQs

A Note on FAQPage Schema

FAQPage is still a valid Schema.org type, and plenty of older SEO guides will tell you to add it. Here's where things actually stand in 2026.

Google fully deprecated FAQ rich results on 7 May 2026. That finished off a process it started back in August 2023, when it limited FAQ rich results to well-known government and health sites only. From that point on, trade, service, and commercial sites stopped getting them anyway.

The deprecation means FAQ dropdowns no longer appear in Google's search results for any website. Search Console's FAQ report and the Rich Results Test support are being removed in June 2026, with API support following in August 2026.

This is a display change, not a markup penalty. Google has said it will keep reading FAQPage data to understand your pages, it just won't render it as a visible search feature. If you have real FAQ content, leaving the markup in place does no harm and there's no rush to strip it out. What no longer makes sense is bolting on FAQ schema purely to grab more space in the results, because that benefit is gone.

What Are Rich Results?

When schema is set up correctly, Google can add visual extras to your listing that make it stand out from the plain blue links around it. For a trades business, the ones that matter most are star ratings, opening hours, service area, and sitelinks.

The difference is easiest to see side by side.

Same business, same page. The richer listing takes up more space and gives people a reason to click before they've even read the description.

A listing with stars and opening hours is a completely different proposition to a plain title and description. It's physically bigger, more informative, and far more likely to win the click over a competitor.

Why Schema Matters for Your Business

Higher Click-Through Rates

Rich results consistently beat standard listings on click-through rate. Stars and opening hours give people more to go on, and more reasons to pick you.

Google Understands You More Precisely

LocalBusiness schema with a defined service area is one of the clearest signals you can send about where you work. It backs up your visibility in the local pack and "near me" searches.

Set It Once, Keep the Benefit

Unlike paid ads, schema is a one-off job with an ongoing payoff. Once it's on your site it keeps telling Google what you do, where you work, and how trustworthy you are, with no monthly bill attached.

Most Competitors Haven't Bothered

Most UK trade websites have no schema at all. That's an edge sitting there for the taking, simply by doing something the business down the road hasn't.

How to Add Schema to Your Website

There are three routes, depending on how technical you want to get.

Option A: Google's Structured Data Markup Helper. A free tool where you highlight elements on your page and Google generates the code for you. Fine for simple LocalBusiness markup.

Option B: Plugins (WordPress / Wix). Tools like Yoast SEO on WordPress or the Wix SEO app can auto-generate basic schema. Quick to set up, but limited in how much you can customise.

Option C: Custom JSON-LD. Add the schema by hand to your site header or individual pages. It takes more effort, but you get full control over every field on every page. This is what we do as standard at WAT Websites.

Schema Implementation Checklist

Get These Right and You're Covered
LocalBusiness schema on your homepage
Service schema on each individual service page
Review / Rating schema if you have reviews
BreadcrumbList schema on inner pages
Test every page with Google's Rich Results Test
Resubmit your sitemap in Search Console once it's added

You can run any page through Google's Rich Results Test for free to check your markup is valid.

Common Schema Mistakes to Avoid

A few mistakes come up again and again. Here's what to watch for.

Using the wrong schema type
Always use the most specific type for your content. A local builder should use LocalBusiness (or more specifically Contractor), not the generic Organization type. More specific means clearer signals.
Marking up content that isn't on the page
Schema has to describe what visitors can actually see. If your phone number is in the schema but not on the page, Google may ignore or penalise the markup. Only mark up what's really there.
Adding it once and forgetting it
If your address, phone number, or hours change, the schema has to change too. Stale schema chips away at Google's trust in your site. Update it whenever your details move.
Not testing after you add it
Run every page through Google's Rich Results Test once the schema is in. Errors in the code quietly stop rich results from ever showing. Test before you move on.
Only adding it to the homepage
Schema belongs on every relevant page, your service pages especially. Each one can carry its own markup describing that specific service. Cover the whole site, not just the front door.
Keyword-stuffing the description fields
Schema descriptions should read naturally and match the page. Cramming keywords into them goes against Google's guidelines. Write them for accuracy, not for keywords.
