For Twenty Twenty-Five theme, which is a Full Site Editing (FSE) block theme, the safest and recommended way to add Google AdSense code is by using a plugin rather than editing theme files directly.
Method 1: Using the WPCode Plugin (Recommended)
Step 1: Install WPCode
In your WordPress dashboard:
Plugins
→ Add New Plugin
Search for:
WPCode
Install and activate the plugin.
Step 2: Add the AdSense Code to the Header
Go to:
Code Snippets
→ Header & Footer
Paste your Google AdSense code into the Header section.
Example:
<script async
src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-xxxxxxxxxxxxxxxx"
crossorigin="anonymous"></script>
Click Save Changes.
Method 2: Using Site Kit by Google (Easiest)
Install Site Kit
Go to:
Plugins
→ Add New Plugin
Search for:
Site Kit by Google
Install and activate it.
Connect Your Google Account
Go to:
Site Kit
→ Start Setup
→ Sign in with Google
→ Connect AdSense
Enable Auto Ads
In your AdSense account:
Ads
→ By Site
→ jldnet.kr
→ Turn Auto Ads ON
Google will automatically place ads throughout your site.
Method 3: Insert Ads Inside Posts
While editing a post:
+ Add Block
→ Custom HTML
Paste your AdSense ad unit code:
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-xxxxxxxxxxxxxxxx"
data-ad-slot="1234567890"
data-ad-format="auto"
data-full-width-responsive="true"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
Method 4: Add a Sidebar Ad
The Twenty Twenty-Five theme does not include a sidebar by default.
You can create one using:
Appearance
→ Editor
→ Templates
Add a two-column layout:
Columns
├── Main Content
└── Ad Area
Then insert a Custom HTML block into the ad column and paste your AdSense code.
