Mismatch The page says one thing, the markup another.
01 / Where to paste schema
Generate, paste,
validate.
01
Generate
Fill only the fields that are true for the live page.
02
Paste
Add the block to your page head, SEO plugin, or CMS schema field.
03
Validate
Run the final page through a schema validator before you leave it live.
02 / Common mistakes
Most schema issues
are mismatch issues.
Mistake 01
Post marked up as a service.
Rule. Do not mark a page as a service page if the copy reads like a blog post.
Mistake 02
Two names, one business.
Rule. Business, product, founder and service names should match the page copy.
Mistake 03
Questions only in the code.
Rule. Do not add FAQ schema unless the same questions and answers are visible on the page.
Mistake 04
Old prices, logos, links.
Rule. Empty or stale fields are worse than a smaller clean block.
03 / Best first pages

What does the schema generator do?
A free, rule-based schema builder for SEO, GEO, and AI search. Choose the page type, fill the fields, then copy the JSON-LD block into your website.
Put the block on the exact page it describes.
Copy the full script block and paste it into the HTML head or schema field for that page. If the schema describes a service page, paste it on that service page. If it describes an FAQ, the questions should be visible on the same page.
Use this for clean starter JSON-LD, not fake certainty.
When to use it
The generator is built for simple page-level schema: Organization, LocalBusiness, Service, FAQ, Article, Product, and BreadcrumbList. It gives you a safe starting block, then the final page still needs a validator check before it goes live.
Schema works best when it matches visible page copy. If the page says one thing and the markup says another, search engines and AI systems get a weaker signal.
Connect schema to the rest of the search surface.
Next checks
After adding JSON-LD, check breadcrumbs, internal links, llms.txt, sitemap coverage, entity names, sameAs links, and visible answer blocks. The goal is clear extraction, not code for its own sake.
Most schema issues are mismatch issues.
Common mistakes
A page can have valid JSON-LD and still send a weak signal if the markup does not match the visible content. Do not mark a page as a service page if the copy reads like a blog post. Do not add FAQ schema unless the same questions and answers are visible on the page.
Watch for old business names, missing breadcrumbs, duplicate Organization nodes, broken sameAs links, placeholder logos, stale product prices, and copied schema that still points to another site. Those small errors make extraction harder than it needs to be.
Start where the business value is clearest.
Best first pages
The first schema pass should usually cover the homepage, main service pages, paid audit pages, reports, resource guides, high-intent tools, and any published proof notes. These pages tell search engines and AI systems what the business does and which answers it can support.
After that, connect the markup to internal links and answer-ready sections. A tidy schema block works better when the page also has a clear heading, a direct summary, useful proof, and a next action.
What does the paid audit include?
The GBP 2,250 audit reviews your public website and up to 12 priority pages, relevant technical findings, up to 3 named competitors and one recorded 20-question ChatGPT panel. Implementation, paid API work, additional providers and ongoing monitoring are outside the standalone audit.
What to check before the block goes live
Match the page type
Use Service for service pages, Article for editorial pages, FAQPage only when the questions are visible, Product only when the page is really selling or describing a product, and BreadcrumbList only when the trail matches the visible site structure.
Keep entity names consistent
Business names, product names, founder names, service names, and URLs should match the page copy. If the title says one thing and the schema says another, the page becomes harder to extract and easier to ignore.
Validate the final page
Test the live URL after publishing, not just the generated block. CMS plugins, themes, redirects, and cached templates can change the final markup after you paste it.
Link it to useful content
Schema is stronger when the page has clear headings, direct summaries, internal links, proof, and answer-ready sections. The code helps crawlers understand a page. It does not rescue a thin page.
Remove stale fields
Do not keep old logos, old prices, broken sameAs links, copied addresses, or placeholder image URLs. Empty or stale fields are worse than a smaller clean block.
Review after site changes
Recheck schema when services, URLs, navigation, pricing pages, reports, or proof pages change. Schema should move with the site, not sit in the page head as forgotten code.
