Missing Structured Data: How to Add Schema Markup

Short answer: structured data is a block of machine-readable code that labels what a page contains, such as your business details, an article, or FAQ answers. If it is missing, search engines and AI tools have to guess. Add it as JSON-LD using schema.org types, then check it in Google's Rich Results Test.

It sits alongside basics like a good title and meta description, and does not replace them.

Step 1: decide which types fit your pages

Only mark up what is actually visible on the page. Common matches:

Check Google's structured data documentation for which types can still earn rich results, since support changes over time.

Step 2: write the JSON-LD

Here is a minimal organization example. Replace the values with your own:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Example Co",
  "url": "https://example.com/",
  "logo": "https://example.com/logo.png",
  "sameAs": ["https://www.linkedin.com/company/example"]
}
</script>

The sameAs links point to your official profiles, which helps identify your brand consistently.

Step 3: add it to your site

• WordPress: use an SEO plugin that outputs schema, and fill in its organization and author settings.
• Other CMS or custom sites: paste the script into the page template, with values generated from page data.
• Make sure the markup is in the delivered page or rendered reliably, see the rendered content gap.

Step 4: validate

Paste the URL into the Rich Results Test or the Schema Markup Validator. Fix errors first, then warnings. After the page is live, Google Search Console reports detected types and problems under "Enhancements".

Step 5: keep it accurate

Update the markup when prices, hours or contact details change. Out-of-date schema is worse than none, and markup that describes content visitors cannot see can lead to a manual action.

Common mistakes

• Marking up content that is not visible on the page.
• Copying another site's schema without changing the values.
• Adding both a plugin's schema and hand-written schema, creating duplicates.
• Leaving required fields empty or using the wrong data type.
• Never revalidating after a redesign or plugin update.
