Short answer

To add schema markup to Duda, open the page's settings from Pages, go to its SEO screen, paste the complete JSON-LD block, script tags included, into Header HTML, save and republish. Details that are true on every page, like your Organization, go once in Settings → Header HTML.

Where it goes: Page SEO settings → Header HTML
Site-wide: Settings → Header HTML

Step by step

How to add it

1
Generate the code
Paste the published page's URL, not the editor's preview link. Copy gives you the block with its <script> tags; Duda's Header HTML keeps code only when it's a complete tag.
2
Find the page's Header HTML
In the editor, open Pages, open the settings for the page, and go to its SEO screen. The Header HTML box is there, next to the meta title and description.
3
Paste and save
Paste the block into Header HTML and save. Duda removes code it considers invalid, so paste the complete block, script tags included.
The page's SEO screen: paste the complete block, script tags included, into Header HTML.
4
Add site-wide details once
For your Organization block, which is true on every page, use More → Settings → Header HTML instead. Keep everything page-specific out of it.
More → Settings → Header HTML: one Organization block for the whole site, nothing page-specific.
5
Republish and verify
Edits go live only after you republish. Then open the live page and check View Page Source for application/ld+json, or run the URL through Google's Rich Results Test.
What the markup tells search engines and AI assistants: the same details your page shows, in a form they can read.

Good to know

A product or service block in the site-wide box would claim every page is about that product. Keep those in the page's own box.

If you're a client on an agency's Duda account and can't see SEO settings, your agency controls that permission. Send them the block, or ask them to turn SEO editing on for you.

Dynamic pages can take a full block per item. Add a text field for the schema to the collection, paste each item's code into it, then open the dynamic page's Header HTML and connect that field with the Connected Data icon.

Duda writes business schema for one location only. For several locations, Duda's own advice is to turn its generated schema off and give each location page its own block.

On your own

How to add schema to Duda manually

Without FullSchema: what the same result takes by hand.

Duda covers part of the job on its own. The rest is up to you, page by page.

1. Complete Business Info first: Duda builds the business markup from the site's Business Info. Fill in the name, address, phone and hours completely, and keep them the same as the site's contact page. Blog posts and native store products get their markup automatically.
2. Write page-specific blocks: For services, locations and FAQs, write a JSON-LD block by hand: the most specific schema.org type, the fields Google's documentation lists, and only details the page shows. Paste it into that page's Header HTML in its SEO settings. On dynamic pages, Connected Data can fill in values from the collection.
3. Validate the live pages: Run the published URLs through the Rich Results Test. Check that your blocks and Duda's automatic business markup list the same phone, address and hours.
4. Keep it current across client sites: Hand-written blocks don't follow page edits. If you manage sites for clients, note which pages carry custom schema so they get updated when the client changes prices, hours or services.

From the forums

What people ask about Duda schema, answered

Collected from Reddit, the Duda community and SEO forums. Straight answers, including the cases where you don't need us.

Duda already adds LocalBusiness schema from Business Info. Will mine conflict?

Two blocks describing the same business aren't an error, but they should agree. If they list different phones or hours, Google picks one. FullSchema reads the details from your live page, so its block matches what visitors see; keep Business Info up to date with the same details.

I pasted the code into Header HTML and it disappeared after saving.

Duda strips code it can't parse. The usual cause is a partial paste, like the JSON without its script tags or a block cut off at the end. Copy again with the Copy button and paste the whole block.

Can I add schema to dynamic pages?

Yes, two ways. Keep a full block per item in a text field of the collection and connect that field in the dynamic page's Header HTML with the Connected Data icon; then each item is a paste into its own field. Or write one block in Header HTML and connect the collection's fields to the values that change, using a generated block for one item page as the model.

We manage dozens of client sites on Duda. Is there a faster way?

Add each client's domain to FullSchema: the free site report lists every page from the sitemap and shows which ones have no schema. Generate for the pages that matter, paste each block into its page's Header HTML, and Monitor tells you when a page changes and its schema no longer matches.

How should a multi-location business set this up?

Give each location page its own block with that location's address, phone and hours, pasted into that page's Header HTML. The home page carries the business as a whole. That way each location can show up for searches near it, and no page claims an address it doesn't list.

The page changed. Do I need to regenerate the schema?

If prices, hours, services or contact details changed, yes: replace the block in the page's Header HTML and republish. Monitor checks your pages every week and tells you when a page no longer matches its schema, so you don't have to remember which ones changed.

About the setup

Duda schema markup questions

Page Header HTML or site-wide Header HTML?

The page's own box for anything about that page. The site-wide box for your Organization only, if at all.

Does Duda put Header HTML in the page source?

Yes. It's added to the <head> of the published page, so crawlers get it without running JavaScript. View Page Source on the live URL confirms it.

My Duda site has several languages. Does each need its own block?

Yes. Each language version is a separate page with its own URL, so each gets a block written in that language, with the text that page shows. Generate for each version's URL.

Ready to generate Duda schema?

Paste your page's URL and FullSchema handles the rest. No dropdowns, nothing to fill in by hand.
