Introduction
If you want better SEO, you need structured data.
For blog posts, BlogPosting schema helps Google understand your content. It can also show rich results.
Many people use plugins for this. But plugins can slow site or create extra load.
If you are using custom theme, better to add it manually.
This guide shows simple way to add schema for all posts without plugin.
What You Need
You want:
- Schema on every post
- No plugin
- No manual edit per post
Best way is using JSON-LD.
Why JSON-LD
Google prefers JSON-LD format.
It is:
- Clean
- Easy to manage
- Works in
<head>
No need to change HTML layout.
Where to Add Code
You can add code in:
functions.php
OR- separate custom PHP file
This will apply to all posts automatically.
Simple Working Code
Add this code:
add_action('wp_head', function() { if (!is_single()) return; $schema = array(
"@context" => "https://schema.org",
"@type" => "BlogPosting",
"headline" => get_the_title(),
"description" => get_the_excerpt(),
"author" => array(
"@type" => "Person",
"name" => get_the_author()
),
"datePublished" => get_the_date('c'),
"dateModified" => get_the_modified_date('c'),
"mainEntityOfPage" => get_permalink(),
"publisher" => array(
"@type" => "Organization",
"name" => get_bloginfo('name')
)
); echo '<script type="application/ld+json">' . json_encode($schema) . '</script>';});What This Code Does
This code:
- Runs on post pages only
- Gets data from WordPress
- Creates schema automatically
- Adds it inside
<head>
So every post gets structured data.
You Can Also Add More Fields
If needed, you can add:
- Featured image
- Category
- Tags
- Custom fields (ACF)
Example:
"image" => get_the_post_thumbnail_url(),
Small Example

After removing plugin and adding this code:
- Site speed improved
- Schema still worked
- No manual work needed
