Is JSON-LD better than Microdata or RDFa?

For most sites, yes. JSON-LD is the format Google recommends because it sits in one tidy block in the head, separate from your HTML, which makes it easier to add, read and maintain than inline Microdata or RDFa.

Will schema markup boost my rankings?

Schema isn't a direct ranking factor, but it helps search engines understand your content and can earn rich results that lift click-through rate. Better understanding and more clicks often lead to better performance over time.

Will this guarantee I get a rich result?

No tool can. Valid markup makes your page eligible, but Google decides whether to show a rich result based on quality, content and its own systems. Filling the recommended fields improves your odds.

Do I need to keep this generator open for my schema to keep working?

No. The generator just produces the code. Once you paste the script block into your page, the schema lives on your site and works on its own — you can close this tab.

Do I need schema markup on every page?

Not necessarily, but it helps on any page with a clear type — articles, products, FAQs, your homepage. Mark up the pages that matter most first, then expand from there.

How do I test my structured data?

Use Google's Rich Results Test or the Schema Markup Validator. Paste your code or enter the live URL and they'll confirm it's valid and show which rich results it's eligible for. The Test in Google button opens it for you.

Is this generator really free?

Yes — completely free, with no signup. Generate as many schema blocks as you need. If you'd rather have schema added to every page automatically, that's what BLG does for you.

What is schema markup?

Structured data and JSON-LD, explained simply

Schema markup is a small block of code that describes your page to search engines in a vocabulary they fully understand — schema.org. JSON-LD is the format Google recommends: a tidy script you drop into your page that spells out what each thing on it is — an article, a product, a business, a FAQ. You write it once; visitors never see it.

Where the markup sits on your page

The JSON-LD lives in a script tag of type application/ld+json, usually inside the head of your HTML. It sits alongside your content, not inside it, so it never changes how the page looks. Search engines and AI crawlers read it to label your content with confidence.

Why add schema markup to your site?

Win rich results and more clicks in Google

Valid structured data makes your pages eligible for rich results — star ratings, FAQs, breadcrumbs and more — that take up more space and earn more clicks than a plain blue link.

Give search engines clearer signals about your content

Schema removes guesswork. Instead of inferring what your page is about, Google reads exactly what each element is, which helps it index and surface your pages correctly.

Help AI search understand and cite you

ChatGPT, Perplexity and Gemini lean on structured data to parse and trust your content. Clear schema makes your pages easier to quote accurately — more on that below.

Which schema type should you use?

Match the type to what the page actually is. The most common ones, one line each:

Article, FAQ, Product, Organization, LocalBusiness

Article — for blog posts, news and guides — the default for most content pages.
FAQ — for a list of questions and answers, on a help or product page.
Product — for an item you sell, with price, availability and reviews.
Organization — for your brand — name, logo and social profiles, usually on the homepage.
LocalBusiness — for a physical location, with address, phone and opening hours.

How to add the markup to your site

Wherever your site is built, the JSON-LD goes in the page's head. Copy the block from the tool, then add it using the method for your platform:

WordPress, Shopify, Webflow, or plain HTML

WordPress

Paste it into a Custom HTML block, or use an SEO plugin like Rank Math or Yoast that has a schema field.

Shopify

Add it to your theme's theme.liquid head, or through your theme's structured-data settings.

Webflow

Open Page Settings → Custom Code and paste the block into the Head section.

Plain HTML

Paste the full script block directly inside the head of your HTML file and publish.

Schema best practices and common mistakes

Do

Only mark up content that's actually visible on the page.
Fill the recommended fields for a richer, more eligible result.
Use JSON-LD — it's the format Google recommends.
Keep your markup in sync when the page content changes.
Validate before you ship, with the Rich Results Test.

Avoid

Marking up content that isn't on the page.
Leaving out the required properties for your type.
Wrong date or URL formats that break validation.
Duplicate or conflicting schema blocks on one page.
Fake reviews or ratings — a fast way to a penalty.

Schema markup and AI search

How ChatGPT, Perplexity and Gemini use structured data

AI answer engines parse structured data to understand entities and relationships fast. Clean schema makes your facts machine-readable, so models can extract and attribute them without guessing.

Structured data and Google's AI Overviews

AI Overviews pull from pages Google understands well. Schema strengthens that understanding, improving your odds of being one of the sources summarized at the top.
