Schema Markup Explained: What It Is and Why AI Cares

Schema markup is code that tells Google and AI platforms exactly what your business does.

Think of it as a business card written in a language computers understand perfectly.

Without it, AI platforms guess what your business does by reading your website like a human. Sometimes they guess wrong.

With it, they know exactly who you are, what you offer, where you are, and what customers think of you.

Here’s everything you need to know in about 11 minutes.

The Business Card Analogy

Without Schema: The Messy Resume

Imagine your website is a resume with no structure.

Bob's Plumbing we do residential and commercial plumbing
in Phoenix since 2005 call us 602-555-1234 emergency
service available 24/7 licensed and insured...

A human can figure this out with effort. A computer has to guess:

Is this a plumber or a plumbing supply store?
Is 602-555-1234 the phone number or a product code?
Is “Phoenix” the location or just mentioned in passing?
Does “24/7” mean they’re open 24/7 or just available for emergencies?

AI platforms make these guesses. Sometimes wrong.

With Schema: The Perfect Business Card

Schema markup is like handing AI a perfectly structured business card.

{
  "Business Name": "Bob's Plumbing",
  "Business Type": "Plumber",
  "Services": ["Residential Plumbing", "Commercial Plumbing", "Emergency Repair"],
  "Phone": "602-555-1234",
  "Address": "123 Main St, Phoenix, AZ 85001",
  "Hours": "Emergency 24/7, Office Mon-Fri 8am-6pm",
  "Founded": "2005",
  "Licenses": ["AZ ROC #12345", "Insured"],
  "Service Area": ["Phoenix", "Scottsdale", "Tempe"],
  "Reviews": {
    "Average": 4.8,
    "Count": 127
  }
}

No guessing required. AI knows exactly what you do and who you serve.

What Schema Markup Actually Is

The Technical Definition

Schema markup is structured data using a standard vocabulary from Schema.org.

It’s HTML code you add to your website that machines can read and understand.

The Practical Definition

It’s information about your business formatted so computers don’t have to guess.

You define:

What type of business you are
What services you offer
Where you’re located
When you’re open
How to contact you
What customers say about you

Why AI Platforms Care About Schema

Reason 1: Speed and Accuracy

When ChatGPT or Perplexity searches for “best plumber in Phoenix”, they analyze hundreds of businesses in seconds.

Without schema:

Read entire website
Guess business type from context
Parse address from footer
Hunt for phone number
Estimate service area
Hope review count is accurate

With schema:

Read structured data instantly
Know exact business type
Get verified address
Find primary phone number
See defined service area
Trust review aggregation

Result: Businesses with schema are easier to evaluate and recommend.

Reason 2: Verification

AI platforms need to verify information accuracy.

Example query: “24/7 emergency plumber Phoenix”

Business A (no schema):

Website mentions “always available”
Footer says “call anytime”
Hours page says “Mon-Fri 8-6”
Conflicting signals

Business B (with schema):

Hours clearly defined: Office Mon-Fri 8-6, Emergency 24/7
Service type includes “Emergency Repair”
No conflict

Winner: Business B. AI trusts structured data over text interpretation.

Reason 3: Matching to User Intent

Schema helps AI match businesses to specific queries.

User asks: “Need a plumber who does commercial work and has liability insurance.”

Without schema:

AI searches website text for “commercial” and “insurance”
Might miss if terms appear in blog posts but not service pages
Can’t verify insurance claim

With schema:

Service type lists “Commercial Plumbing”
Insurance certification included in structured data
Perfect match confirmed in seconds

Types of Schema That Matter for AI Visibility

1. LocalBusiness Schema (Most Important)

This tells AI you’re a local business.

What it includes:

Business name
Type (Plumber, HVAC, Lawyer, Restaurant, etc.)
Address
Phone
Hours
Geographic service area
Payment methods accepted

Why it matters: This is the foundation. Without it, AI might not recognize you as a local business.

2. Service Schema

This defines what services you offer.

Example for HVAC company:

{
  "Services": [
    {
      "name": "AC Repair",
      "description": "Emergency and scheduled AC repair",
      "areaServed": ["Phoenix", "Scottsdale", "Tempe"]
    },
    {
      "name": "HVAC Installation",
      "description": "New system installation for residential and commercial",
      "areaServed": ["Phoenix", "Scottsdale"]
    }
  ]
}

Why it matters: Helps AI match you to specific service queries.

3. Review Schema (AggregateRating)

This displays your review count and average rating.

What it includes:

Average star rating
Total number of reviews
Best and worst possible rating

Why it matters: AI platforms heavily weight reviews in recommendations. Schema makes your review data trustworthy.

4. Organization Schema

This defines your company identity.

What it includes:

Logo
Social media profiles
Founded date
Organization type
Parent organization (if applicable)

Why it matters: Helps AI understand your authority and longevity.

5. FAQPage Schema

This structures your FAQ content.

What it includes:

Question and answer pairs
Formatted for direct display

Why it matters: AI platforms often pull FAQ answers directly. This helps you appear in featured responses.

How to Check If You Have Schema

Method 1: Google Rich Results Test (Free)

Go to search.google.com/test/rich-results
Enter your website URL
Click “Test URL”
See what schema Google detects

What you’ll see:

Detected schema types
Errors or warnings
Missing recommended fields

Method 2: View Page Source (Manual)

Visit your homepage
Right-click and select “View Page Source”
Search for "@type" or "schema.org"
If you find it, you have schema
If not, you don’t

Method 3: Surmado Scan ($25)

Surmado Scan checks your schema and tells you:

What schema you have
What’s missing
What’s misconfigured
Priority fixes for AI visibility

Run Surmado Scan for complete analysis

How to Add Schema to Your Website

Option 1: Use a Plugin (Easiest for WordPress)

For WordPress sites:

Install Yoast SEO or Rank Math plugin
Go to plugin settings
Enable Schema features
Fill in business information
Select business type
Save

Time: 30-60 minutes

Cost: Free (both plugins have free versions)

Limitation: Basic schema only. May miss service-specific details.

Option 2: Use Google’s Structured Data Markup Helper (Free, Manual)

Go to Google’s Structured Data Markup Helper
Select “Local Business”
Enter your website URL
Tag elements (business name, address, phone, etc.)
Generate HTML
Add to your website

Time: 1-2 hours

Cost: Free

Limitation: Requires basic HTML knowledge.

Option 3: JSON-LD Manual Implementation (Most Control)

Hire a developer to add JSON-LD schema.

What they’ll add:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Plumber",
  "name": "Bob's Plumbing",
  "image": "https://example.com/logo.png",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "123 Main St",
    "addressLocality": "Phoenix",
    "addressRegion": "AZ",
    "postalCode": "85001"
  },
  "telephone": "+1-602-555-1234",
  "priceRange": "$$",
  "openingHoursSpecification": [
    {
      "@type": "OpeningHoursSpecification",
      "dayOfWeek": ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"],
      "opens": "08:00",
      "closes": "18:00"
    }
  ],
  "areaServed": [
    {
      "@type": "City",
      "name": "Phoenix"
    },
    {
      "@type": "City",
      "name": "Scottsdale"
    }
  ],
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": "4.8",
    "reviewCount": "127"
  }
}
</script>

Time: 2-4 hours for developer

Cost: $200-500 depending on complexity

Benefit: Complete control, all schema types, no plugin overhead.

Option 4: Schema Generator Tools (Middle Ground)

Tools:

How it works:

Select business type
Fill in form with business details
Generate JSON-LD code
Copy and paste into website header

Time: 30-60 minutes

Cost: Free

Limitation: Still need to add code to website manually.

Common Schema Mistakes

Mistake 1: Incorrect Business Type

Wrong:

"@type": "Organization"

Right:

"@type": "Plumber"

Why it matters: “Organization” is generic. “Plumber” is specific. AI platforms match based on type.

Fix: Use the most specific business type from Schema.org business types.

Mistake 2: Missing Service Area

Incomplete:

"address": "123 Main St, Phoenix, AZ"

Complete:

"address": "123 Main St, Phoenix, AZ",
"areaServed": ["Phoenix", "Scottsdale", "Tempe", "Mesa", "Chandler"]

Why it matters: AI needs to know if you serve the area someone is asking about.

Fix: Explicitly list all cities you serve.

Mistake 3: Conflicting Information

Problem:

Schema says open Mon-Fri 9-5
Website footer says “Available 24/7”
Google Business Profile says Mon-Sat 8-6

Why it matters: AI sees conflicting data and may not recommend you.

Fix: Make sure schema, website text, and Google Business Profile all match.

Mistake 4: Missing Reviews Schema

Incomplete schema:

Business name ✓
Address ✓
Phone ✓
Reviews ✗

Why it matters: Reviews are a huge trust signal. If your schema doesn’t include review aggregation, AI can’t verify your rating.

Fix: Add AggregateRating schema with your average rating and review count.

Mistake 5: Not Updating Schema

Problem:

Schema says you’ve been in business since 2005
Today is 2024
You have 127 reviews
Schema still says 43 reviews from 2022

Why it matters: Stale data makes AI think information is unreliable.

Fix: Update schema quarterly (at minimum). Update immediately when key facts change (new location, phone number, service additions).

Expected Results Timeline

Week 1-2: Google Re-indexes

After adding schema:

Google re-crawls your site (1-7 days)
Rich results test shows new schema (immediately)
Google Search Console shows enhancement (3-7 days)

Week 2-3: AI Platforms Recognize Updates

AI platforms re-index your site:

ChatGPT with search sees new structure
Perplexity updates business information
Gemini recognizes schema
Other platforms follow

Week 3-4: Improved Recommendations

You start appearing in more AI search results:

Better matching to specific queries
Higher trust score
More accurate business description
Improved competitive standing

Week 4-8: Measurable Improvement

You can measure the difference:

Re-run Surmado Signal test
Compare presence rate before and after
Check if AI quotes are more accurate
See if you appear for more persona types

How to Measure Schema Impact

Test 1: Before and After Presence Rate

Before schema:

Run Surmado Signal with 5 personas
Note presence rate (example: 20%)

After schema:

Wait 3-4 weeks
Re-run with same personas
Compare presence rate (target: 40-60%)

Test 2: Accuracy of AI Descriptions

Before schema:

“Bob’s Plumbing in Phoenix offers plumbing services.”

After schema:

“Bob’s Plumbing in Phoenix provides residential and commercial plumbing, including 24/7 emergency repair. Serving Phoenix, Scottsdale, and Tempe since 2005. Rated 4.8 stars from 127 reviews.”

Improvement: More specific, more accurate, more trustworthy.

Test 3: Google Rich Results

Check Google Search Console:

“Enhancements” section
Look for “Unparsable structured data” errors
Fix errors
Monitor improvement

Schema and SEO: The Relationship

Schema helps SEO in 4 ways.

1. Rich Snippets in Google

Schema can trigger rich snippets:

Star ratings
Business hours
Price range
Event information

Impact: Higher click-through rate from search results.

2. Knowledge Graph

Google uses schema to build knowledge graph panels.

Example: Search “[your business name]” and see knowledge panel on right with map, reviews, hours, etc.

Schema feeds this data.

3. Voice Search Optimization

Google Assistant, Siri, and Alexa rely on schema for answers.

Query: “OK Google, find a plumber near me that’s open now.”

Google’s process:

Find plumbers near user
Check schema for hours
Return businesses marked as currently open

Without schema: You might be open but Google doesn’t know.

4. AI Search (As Discussed)

Same schema that helps Google helps ChatGPT, Perplexity, and other AI platforms.

One implementation. Multiple benefits.

Frequently Asked Questions

Do I need schema on every page?

No. Most important on homepage and location pages.

Service pages benefit from Service schema.

Blog posts can use Article schema but lower priority.

Will schema guarantee I appear in AI search?

No. Schema is one signal among many. But it’s a strong signal that’s fully under your control.

Think of it as removing barriers. Without schema, AI has to guess. With schema, AI knows for sure.

Can I add schema myself or do I need a developer?

Depends on your website platform.

WordPress: Use plugin, no developer needed.

Custom website: Probably need developer unless you’re comfortable editing HTML.

Shopify/Squarespace/Wix: Check if platform has built-in schema or plugins.

How often should I update schema?

Immediate updates:

Phone number changes
Address changes
Hours changes
New services added

Quarterly updates:

Review count and average rating
Service areas (if expanding)

Annual updates:

Verify all information is current
Check for new schema types relevant to your business

Does schema help local SEO?

Yes. Google uses schema for:

Local pack rankings
Knowledge panel
Rich snippets

Same schema helps both Google and AI platforms.

The Bottom Line

Schema markup is structured data that tells AI platforms exactly what your business does.

It’s like handing AI a business card instead of making it read your website and guess.

Benefits:

Faster evaluation by AI platforms
More accurate business descriptions
Better matching to user queries
Higher trust score
Improved visibility in both Google and AI search

Time to implement: 30 minutes with plugin, 2-4 hours with developer

Cost: Free to $500 depending on method

Impact timeline: 3-4 weeks to see results

Expected improvement: 20-40% increase in AI search presence rate

You can’t control whether AI recommends your business. But you can make it easy for AI to understand you. Schema does that.
