What is structured data, and does a service business website need it?

Structured data is a block of code, usually invisible to visitors, that describes what a page is about in a fixed vocabulary. Google's documentation defines it as "a standardized format for providing information about a page and classifying the page content." Instead of guessing that a string of numbers is your phone number, a search engine reads a field labeled telephone.

The vocabulary comes from schema.org, a shared project supported by the major search engines, which is why people also call it schema markup. Google supports three formats and says it recommends JSON-LD if your site setup allows it. JSON-LD sits in one script block in the page code, so it does not get tangled up with your design.

Yes, in a small, focused form. Structured data helps search engines connect your website to your business: your name, location, hours, phone number, logo and the profiles that belong to you. That matters for a law office with two locations, a med spa that changed its hours, or an auto repair shop whose name is close to another shop across town.

Google's own case studies show what rich results can do in other sectors. Google's structured data introduction reports that Rotten Tomatoes saw a 25% higher click-through rate on pages with structured data and that Nestle measured an 82% higher click-through rate on pages shown as rich results. Those are large publishers, not local service firms, so treat them as a sign of what is possible, not a forecast.

Structured data does not guarantee anything. Google says pages must meet its guidelines and include required properties to be eligible, and even then it decides whether to show a rich result.

Start with these, in this order:

• LocalBusiness: Google lists name and address as required, with telephone, url, opening hours, geo coordinates and price range recommended. Use the most specific subtype that fits, such as Dentist, LegalService, AutoRepair, HairSalon, RealEstateAgent or HealthClub. One block per physical location, on that location's page.
• Organization: Google says to add it to your home page or about page, not every page. Include your logo (at least 112 by 112 pixels), url and sameAs links to your official social and review profiles. This helps Google pick the right logo and tell you apart from similar names.
• BreadcrumbList: shows where a page sits in your site, such as Home, Services, Teeth Whitening. Google uses it to display a breadcrumb trail in results on desktop.
• Service: schema.org has a Service type for describing individual offerings. Google does not show a rich result for it, so treat it as optional context, worth adding only if your site platform makes it easy.

Not for Google rich results. Google narrowed FAQ rich results to well-known government and health sites in August 2023, then its documentation changelog recorded that FAQ rich results stopped appearing in Google Search on May 7, 2026. The FAQ documentation was removed in June 2026.

The questions themselves are still valuable. A clear FAQ section answers the objections people have before they book, and it gives search engines and AI tools plain, quotable answers. Keep the visible FAQs. Existing FAQPage markup does no harm, but do not spend new budget on it.

Indirectly. Google's page on AI features says there is "no special schema.org structured data that you need to add" to appear in AI Overviews or AI Mode, and its 2026 AI optimization guide repeats that structured data is not required for generative AI search. The same guide still recommends it because it helps with rich result eligibility.

Other search engines describe it differently. Search Engine Land reported in 2025 that Microsoft's Fabrice Canel said Bing and Copilot use schema markup to help their language models understand content.

The practical takeaway: accurate structured data is a supporting signal. The page content still has to answer the question. Markup that describes services you do not show on the page, or reviews you did not collect, is against Google's guidelines and can cost you eligibility.

Most site builders and content systems have a way to add it. Some generate LocalBusiness and Organization markup from your settings; others need a plugin or a code block in the page header.

• Write down the facts first: legal name, the name customers know you by, each address, hours (including holiday and seasonal hours), main phone, logo file and your official profile URLs.
• Check those facts match your Google Business Profile exactly. Mismatched hours or phone numbers are a common problem.
• Add LocalBusiness markup to each location page and Organization markup to the home or about page.
• Run each page through Google's Rich Results Test, which validates markup and previews eligible features. The Schema Markup Validator at validator.schema.org checks general schema.org syntax.
• After launch, use the URL Inspection tool in Search Console to confirm Google sees the markup, and check the rich result reports for errors.
• Put a recurring task on the calendar to update markup whenever hours, addresses or services change.

Most problems come from markup drifting away from reality. Common ones include hours in the markup that differ from the hours on the page, a single LocalBusiness block covering three locations, review stars added to your own business pages (Google limits self-serving review markup), and a plugin and a theme both outputting conflicting Organization data.

Monvell's development team builds structured data into every site from the business facts the client approves, then checks it in the Rich Results Test before launch. It is one of the items the free digital audit reviews.
