How to Create and Add Schema Markup Manually in WordPress 

Have you ever searched for something on Google and noticed extra details? Like ratings, author names, FAQ boxes, or prices are shown under some websites? That’s called Schema Markup, also known as Structured Data.

Schema markup helps Google understand your content better and display rich results. It’s like giving search engines a clear description. Basically, what your page is about. Whether it’s a blog, a product, a recipe, or a local business. Most people use SEO plugins like Rank Math or Yoast SEO for schema. But what if you want to add schema markup manually in WordPress without plugins? At this point, your mind may be looking for several answers.

So let’s go step-by-step and learn how to create and insert a schema manually. By using simple methods, even if you’re not a coder.

What Is Schema Markup and Why Does It Matter

Schema markup is a small piece of code. It is usually written in JSON-LD format, which helps Google understand what your page is about. Think of it like a label that tells search engines, “Hey Google, this page is an article!” or  “This is a product page with price and reviews.”

When you add schema correctly, your pages can show rich results in Google. Like stars, ratings, event dates, or FAQs. You can learn more about SEO structure and canonical tags in our Wideripples SEO Guide.

Different Schema Types You Can Use

You can add a schema for many types of content. Here are some common ones used in WordPress:

• Article Schema: For blogs and news posts.
• FAQ Schema: For Q&A sections.
• Product Schema: For eCommerce pages.
• LocalBusiness Schema: For small businesses and stores.
• HowTo Schema: For step-by-step guides.

Example: If you write tutorials, use the How To Schema. If you sell items, use Product Schema.

The Best Format for Schema

There are three main formats:

• Microdata
• RDFa
• JSON-LD

JSON-LD (JavaScript Object Notation for Linked Data) is the best choice. Why? Because it’s clean, easy to read, and Google recommends it.

Why Add Schema Markup Manually?

You might wonder, “Why not just use a plugin like Yoast schema or Rank Math schema?”

Plugins are great, but a manual schema gives you full control over code. Also less dependency on plugins. Custom schema types (like FAQ, Product, LocalBusiness, or HowTo). Better speed and More accuracy for Google validation

Manual schema is perfect for developers, small sites, or anyone who prefers a clean, lightweight setup.

How to Create Schema Markup Manually

Let’s go step by step.

Step 1: Choose Your Schema Type

Decide what kind of page you’re adding schema to:

• Blog → Article
• Product page → Product
• Local business → LocalBusiness
• FAQ page → FAQPage
• Tutorial → HowTo

Example: If it’s a blog post, choose Article Schema. You can check all schema types at schema.org.

Step 2: Generate or Write the Schema Code

You can either create a schema manually or generate it using free schema tools.

Here’s a basic FAQ Schema example:

Option 2: Use Free Schema Tools

If coding feels difficult, use:

• Google’s Structured Data Markup Helper
• Merkle Schema Generator
• JSON-LD Generator

These tools create schema code automatically. You just copy and paste it.

Step 3: Add Schema to WordPress

There are 3 main ways to add schema markup manually in WordPress:

Option 1: Add in Header.php

You can paste the schema script directly before the closing </head> tag.

Steps:

1. In your WordPress dashboard → Appearance → Theme File Editor
2. Open header.php
3. Add your schema code before </head>
4. Click Update File

Example:

 Option 2: Add via Custom Fields (Per Page)

If you want a different schema for each post:

1. Edit the post.
2. Scroll to Custom Fields (enable via Screen Options if hidden).
3. Create a new field (e.g., custom_schema).
4. Paste your JSON-LD code as a value.

This way, each post can have a unique schema (great for News Schema or Product Schema).

Step 4: Validate Your Schema

After adding your schema, test it using:

• Google Rich Results Test
• Schema.org Validator
• Structured Data Testing Tool

These tools check if your code is correct and if your page qualifies for rich results.

Schema Markup Without Plugin (Manual Method)

Adding schema manually has these benefits:

• No plugin bloat or conflict.
• Total control over data and updates.
• Faster load time.

But it also requires care. If you’re unsure, verify your code using Google tools 

Common Mistakes to Avoid

• Duplicating schema (plugin + manual).
• Forgetting to close brackets in JSON.
• Using the wrong schema type.
• Adding schema inside HTML instead of JSON-LD.
• Keep your code clean, valid, and tested.

Schema Best Practices for WordPress

• Use JSON-LD format.
• Add it in <head> wp_head.
• Validate before publishing.
• Use only one schema type per page unless they’re related.
• Update schema when content changes
