FAQ Schema and Structured Data for Home Service Websites: What to Add and What to Skip

Structured data is a block of code on a web page that describes the page's content in a standard format that search engines and other automated systems can read. For a home service company it can state your business name, phone number, services and service area, and it can mark up the questions and answers on a page. It does not guarantee a special result in search or in AI tools, but it removes guesswork about what your page is.

This guide covers what to add, how to write it and how to avoid mistakes, in language a business owner can follow and hand to a developer.

What structured data actually is

The most common format is JSON-LD, a small script placed in the page, using the vocabulary from Schema.org. A person never sees it, but a crawler can read it. Think of it as a label on a box. The text on the page is the contents, and the markup says this box contains a plumbing business, here is its phone number and these are the areas it serves.

The golden rule is that the markup must describe what is visible on the page. Marking up reviews you do not show, services you do not offer or answers that do not appear on the page violates search guidelines and can cause the markup to be ignored.

Start with your business

The foundation is an organization or LocalBusiness record on your home page. Use the most specific type that fits, for example Plumber, HVACBusiness or RoofingContractor, which exist in the Schema.org vocabulary. Include your name, website, phone number, email, logo, social profile links and, if you are a service-area business, the areas you serve. If customers can visit a location, include the address. If they cannot, do not invent one.

Make sure the details match your Google Business Profile exactly. Mismatched names, numbers or addresses between the markup, the page and your profile cause confusion for systems that try to connect them.

Describe your services

For each core service page, you can add a Service record that names the service, describes it briefly, links it to your business as the provider and lists the area served. Keep the description short and factual and mirror the text on the page. Do not add price ranges unless the page states them and you keep them up to date.

Service markup helps clarify what each page is about. It works best on pages with unique, well-written content, because the markup supports the page and never rescues a thin one.

Where FAQ markup fits

FAQ markup, called FAQPage in Schema.org, labels a list of questions and their answers. It is appropriate when the page itself shows those questions and answers to visitors, written by you, with each question having one answer. It is not meant for forms where visitors submit questions, for advertising or for hidden text.

Be aware that search engines decide how, and whether, to display FAQ-based features, and their policies have changed over time. In recent years Google has limited the visual FAQ results it shows for many sites. Even so, a clear question-and-answer section remains valuable for readers, and clean markup can still help machines understand the content. Treat it as a clarity measure, not a way to claim extra space on the results page.

Write answers worth marking up

A good FAQ answer is direct, specific and honest. Begin with the answer in the first sentence and add a short explanation. For example, if the question is how long does a water heater replacement take, answer with what you typically see for a standard tank unit, explain what can lengthen the job, such as relocated piping or code upgrades, and say that the technician will confirm the timing after inspecting the site.

Avoid answers that only say call us for details. Customers and answer engines both prefer real information. Keep the number of questions manageable, usually five to eight per page, and make sure each belongs on that page.

Mind the Review and Rating markup

Be cautious with review and aggregate rating markup. Google's guidelines restrict self-serving reviews, meaning ratings a business marks up about itself on its own pages in certain cases, and they require the reviews to be genuine and visible. The safest path is to display real reviews from a trusted source and not to mark up ratings unless you have read the current rules and your implementation matches them. Fake or inflated ratings can cost you the markup and your credibility.

Add breadcrumbs and article data where they belong

Breadcrumb markup shows the path from your home page to the current page, such as Home, Insights, then the article title. It helps systems understand your site structure. For blog posts, Article markup should name the headline, the author or organization, the publication date and the date of the last update, all of which should match what readers see. Keep dates honest. Updating the modified date without changing the content makes your site look careless.

Test before and after you publish

Use Google's Rich Results Test to see which features your markup supports, and the Schema Markup Validator to check syntax against the Schema.org vocabulary. Fix errors first and warnings when they are relevant. After publishing, watch the enhancement reports in Search Console, which show problems that appear over time. Test again whenever you redesign a page, since a template change can quietly break the markup.

Common mistakes

The usual problems are marking up content that is not on the page, copying another company's code with their name still in it, using several conflicting business records on one page, leaving placeholder phone numbers in place and forgetting to update the markup when a service or number changes. Another is treating schema as a shortcut. Pages with weak content do not become strong because of the code underneath them.
