Schema markup is a small piece of code on your website that describes your business in a format machines can read without guessing. Visitors never see it, but search engines and AI tools rely on it.
Without schema, Google has to infer that '555-0142' is your phone number and 'Mon–Fri 8–6' are your hours. With schema, you state it outright.
Why it matters more now
Search engines have used structured data for years to power rich results like star ratings and FAQs. AI tools add another reason to care: the clearer your information is, the easier it is for them to describe your business accurately and confidently.
The schema types most businesses need
LocalBusiness (or a more specific type such as Dentist, Plumber or LegalService) covers your name, address, phone, hours and service area. Organization connects your brand to your logo and social profiles. Service describes what you offer. FAQPage marks up common questions and answers. Article or BlogPosting describes your blog content.
Common mistakes
The biggest one is markup that doesn't match the page. If your schema lists services or reviews that visitors can't see, search engines may ignore it or treat it as spam. Others include outdated hours, missing service areas, and plugins that add generic markup nobody ever reviewed.
How to check yours
Google's Rich Results Test and the Schema.org validator will show what structured data is on any page. If you see nothing, or only a bare website name, you have an easy improvement waiting.
Schema won't rescue a weak website on its own, but on a site with good content it's one of the highest-value technical fixes you can make.
