Schema Markup for Contractor Websites: What to Add and How to Validate It

Structured data gives search engines a machine-readable description of the information on a page. For a contractor website, the useful starting point is accurate business and service information. Markup should describe that information faithfully, not add claims that customers cannot verify on the page.

Google recommends JSON-LD and also supports Microdata and RDFa. Valid markup does not guarantee a rich result, a ranking improvement, or an AI recommendation. Read Google's structured data guidelines.

Start with verified business information

Evaluate LocalBusiness markup and the most appropriate supported subtype when the page represents a local business. Use genuine details such as the business name, address where applicable, contact information, and opening hours. Check Google's required and recommended properties for the feature you are implementing. Do not invent an address, rating, or credential to satisfy a validator.

Keep these details consistent with the visible site and update them when the business changes. A complete-looking block with inaccurate information is not a successful implementation. Google's LocalBusiness documentation explains the supported properties and requirements.

Describe each service clearly

Schema.org's Service type can describe a service, its provider, and the area served. Use it to represent the actual offering on the page. For example, an AC repair page should describe AC repair and the business providing it, with service areas the business genuinely covers.

A vocabulary type existing on Schema.org does not by itself establish eligibility for a Google rich result. Check the documentation for the particular search feature separately. See the Service vocabulary and Google's supported structured-data features.

Represent navigation with breadcrumbs

BreadcrumbList describes a page's position in a site's hierarchy. Build the trail around useful navigation, with accurate names, positions, and URLs, and validate it against Google's requirements. Treat the markup as a description of the hierarchy, not a guaranteed click-through improvement. See Google's breadcrumb documentation.

Do not sell FAQ markup or review stars as guaranteed results

Google stopped showing FAQ rich results on May 7, 2026. Useful question-and-answer content can still help visitors, but FAQPage markup is not a ticket to an FAQ search feature or an AI citation. Google's generative search guidance does not require special schema or a particular writing format. See the FAQ retirement notice and Google's AI search guidance.

Google also excludes self-serving LocalBusiness and Organization reviews from its review-star feature. Adding an aggregate rating to your own business website does not make it eligible for those stars, including when the reviews come through an embedded third-party widget. Read the review snippet guidelines.

Validate the implementation and inspect the live page

1. Compare the markup with the visible page and verified business records. Check facts as well as syntax.
2. Use Google's Rich Results Test for supported Google features. Use the Schema.org validator to inspect vocabulary markup more broadly. A missing rich-result detection does not prove that a page contains no structured data.
3. After deployment, inspect the actual page and use Search Console's URL Inspection tool to check how Google accesses it. Monitor relevant reports as data becomes available.
4. Recheck the markup when business details, page content, site structure, or platform requirements change.

Open the Rich Results Test or the Schema.org validator. These checks help identify implementation problems. They do not certify every factual claim or guarantee search visibility.
