    How do I create schema markup?

    Choose the type of page, such as a local business or an article, fill in the fields and copy the JSON-LD block the tool builds. Paste it into the page's head or body. Empty fields are left out so you never publish blanks, and the checks list anything Google expects that is missing. Markup must describe content visitors can actually see on the page, and it should be tested with Google's Rich Results Test before you publish.

    What schema markup is for

    Schema markup is a standard vocabulary, from schema.org, for describing what a page is about in a form machines can read. Google recommends writing it as JSON-LD, a script block that sits apart from the visible page, and uses it to understand the page and, for some types, to show richer results. It is not a ranking switch: it helps search engines understand who you are and what the page contains, and it makes some features possible, but it does not by itself lift a page.

    Four types are covered. Organization states your name, website, logo and profiles. LocalBusiness adds an address, opening hours, telephone number and the kind of business, with a choice of more specific types such as Plumber, Dentist or Restaurant. Article describes a post with its headline, images, dates and author. BreadcrumbList describes the path to a page. For questions and answers use the FAQ schema generator.

    It runs in your browser. Nothing you enter is sent anywhere, and there is no sign-up.

    Keeping it honest

    Only mark up what is true and visible. Do not add ratings, reviews, prices or opening hours that the page does not show, and do not invent them: Google treats misleading markup as a violation of its guidelines and can remove rich results for the site. That is why this generator has no review or rating fields. Use the same name, address and telephone number as on your website and your Google Business Profile, spelled the same way, so every source agrees. Check the finished block in the Rich Results Test, and keep it up to date when your hours or address change.

    When to use it

    • Adding local business details to a home or contact page
    • Marking up blog posts with author and dates
    • Adding a breadcrumb trail
    • Checking what fields a type needs

    Mistakes it helps you avoid

    • Marking up content that is not on the page.
    • Inventing reviews or ratings.
    • Using an address or phone number that differs from the page.
    • Leaving the date, image or author out of an article.

    The formula

    How the answer is worked out.

    • 1. Choose the type and fill in the fields you have.
    • 2. Each filled field becomes a property in a JSON-LD object with @context https://schema.org.
    • 3. Opening hours lines such as Monday-Friday 08:00-17:00 become OpeningHoursSpecification entries.
    • 4. The object is written as formatted JSON inside <script type="application/ld+json">, with < escaped.

    Property names follow schema.org and Google's documentation for each type. Dates should use ISO 8601 (2026-10-26). Latitude and longitude are written as numbers. The generator checks for missing common fields, not for whether Google will show a rich result.

    Example: a plumber in Calgary

    You choose Local business, kind Plumber, and enter name, address and hours.

    1. @typePlumber
    2. Hours lineMonday-Friday 08:00-17:00

    A JSON-LD block with PostalAddress and an OpeningHoursSpecification for five days

    Test it in the Rich Results Test.

    Common questions

    Where do I put JSON-LD?

    In the head or body of the page, inside a script tag of type application/ld+json.

    Does schema improve rankings?

    Not directly. It helps search engines understand the page and can enable rich results.

    Can I add star ratings?

    Only for real reviews shown on the page. This generator leaves them out on purpose.

    Which format does Google prefer?

    JSON-LD.

    Is my data sent anywhere?

    No.

    Is anything I enter sent to a server?

    No. The calculation happens in your browser and nothing you type leaves your device.
