Schema markup generator that fills the gaps on each page

The Axiom GEO schema markup generator builds copy-paste JSON-LD for a single page. It covers Organization, Article, FAQPage, LocalBusiness, Service and BreadcrumbList, and only offers types the page does not already have. LocalBusiness markup takes its address and rating from your Google Business Profile. It uses no AI and costs no credits.

Key points

  • It builds JSON-LD for six common schema types, ready to paste into a page.
  • It checks what the page already has and only fills the gaps, so you do not end up with duplicate markup.
  • LocalBusiness markup uses the address and rating from your Google Business Profile.
  • No AI model is involved, so the output is the same each time and costs no credits.
  • It sits next to page analysis and the entity audit, which show where markup is missing or broken.

What does the schema generator answer for you?

It answers a simple question. What structured data is this page missing, and what should the code look like? You pick a page and get back JSON-LD you can paste straight in.

Most sites have some schema already. A theme or plugin adds a bit, a developer added a bit years ago, and nobody is quite sure what is there. The generator checks first and only builds the types the page does not have. That keeps you away from duplicate or clashing blocks.

How does it work?

The process is short and there is nothing to set up beyond your site and your Google Business Profile.

  1. Pick a page. The site crawler has already found your pages, so you choose one from the list.
  2. Check what is there. The generator reads the structured data the page already carries.
  3. See what is missing. It offers only the schema types the page does not yet have.
  4. Fill in the details. For LocalBusiness it takes the address and rating from your Google Business Profile.
  5. Copy and paste. You get a JSON-LD block ready to drop into the page or your content system.

Because no AI model is involved, the same page gives the same output each time. It also costs no credits, so you can work through a whole site without thinking about spend.

Which schema types can it build?

It covers the six types most business sites need. The table shows what each one describes and where it usually goes.

Schema typeWhat it describesWhere it usually goes
OrganizationThe business itself, its name, logo and linksHome page or about page
ArticleA written piece with its author and datesBlog posts and guides
FAQPageQuestions and answers shown on the pageFAQ sections
LocalBusinessA place with an address and ratingLocation and branch pages
ServiceA service you offerService pages
BreadcrumbListWhere the page sits in the siteMost inner pages

If you want the background on each format, the JSON-LD and schema markup glossary entries explain them in plain terms.

What do you see?

You see the page, the types it already has, and the types it could add. For each missing type you get the finished code block. LocalBusiness blocks show the address and rating pulled from your profile, so you can check them before you paste.

It helps to read the output once before it goes live. If your profile has an old address, the markup will carry that old address too. Fixing the profile first is usually the quicker route.

What mistakes does it help you avoid?

The most common problem we see is doubled markup. A plugin adds an Organization block, then someone pastes a second one with a slightly different name. Machines now have two versions of you to choose between. Because the generator checks the page first, it will not add a type that is already there.

The second problem is markup that says something the page does not. An FAQPage block with questions that are not visible on the page is a good example. It is worth keeping the markup and the visible text in step.

How is this different from a free online schema generator?

Most free generators are forms. You type in every detail by hand and they give you code, with no idea what your page already carries. That is fine for one page. It gets slow and error-prone across a site with dozens of service and location pages.

Here the generator already knows your pages from the crawl and your locations from Google Business Profile. It also sits in the same login as the checks that told you the markup was missing. So you find the gap, fix it and run the page check again, all in one place.

Structured data states facts in a form a machine can read without guessing. Your name, address, services and authors are all spelled out. That makes it easier for search engines and AI systems to connect your pages to one clear entity.

It is not a switch that turns on AI mentions. AI engines weigh many things, and nobody can promise a citation. What schema does is remove doubt about who you are and what you do. Our guide on schema markup for AI search goes through what matters and what does not.

Who uses it?

Agencies use it to tidy up client sites quickly without a developer for every change. The agencies page covers how that fits into client work. Local firms with several branches use it to add LocalBusiness markup to each location page. In-house teams use it alongside page analysis to clear the structured data checks that fail.

Where it fits

The generator is the fix step. Page optimisation scores each page on structured data and other signals and tells you where markup is missing. The entity audit checks whether your markup joins up across the whole site. Content packs come with their own FAQPage, Person and Article JSON-LD, so new pages start with markup in place.

Frequently asked questions

Is the schema markup generator free to use?

Yes, within your plan it costs nothing extra. The generator uses no AI and no credits, so you can run it on as many pages as you like. Credits are only spent on actions such as AI engine queries and rank checks, and every credit spent is logged.

Which schema types can it create?

It creates Organization, Article, FAQPage, LocalBusiness, Service and BreadcrumbList. LocalBusiness includes the address and rating from your Google Business Profile. It only offers the types a page does not already have, so it will not suggest a second Organization block if one is there.

Does schema markup help you appear in ChatGPT or AI Overviews?

It helps, but it is no guarantee. Structured data states facts about your business in a form machines read without guessing. That makes it easier for search engines and AI systems to be sure who you are. No one can promise a mention from markup alone.

How do I add the JSON-LD to my website?

Copy the block and paste it into the page, usually in the head or just before the closing body tag. Most content systems, including WordPress, let you add a script block to a single page. After that it is worth testing the page with a structured data testing tool.

What is the difference between the schema generator and the entity audit?

The generator writes markup for one page. The entity audit looks across your key pages and checks whether the markup joins up into one clear picture of the business, with stable @ids, name variants and authors as Person entities. Most people run the audit first, then use the generator to fix gaps.

Why does it not use AI to write the schema?

Schema should state facts exactly, so it is built from data you already hold rather than written by a model. That keeps the output the same each time you run it and means there is nothing to check for made-up details. It also keeps the cost at zero credits.
