WordPress

AdXensor integrates with WordPress using the CDN snippet. No plugin is required — the script tag is added manually to your theme or through a WordPress hook.

Adding the AdXensor script

functions.php (recommended)
Header & Footer plugin
header.php

This method adds the AdXensor script tag to every page of your site via wp_enqueue_scripts.

Open your theme's functions.php

Go to Appearance → Theme File Editor in the WordPress admin, or edit the file directly via SFTP/SSH:

wp-content/themes/YOUR-THEME/functions.php

Add the following snippet

<?php
function adxensor_enqueue_script() {
    wp_enqueue_script(
        'adxensor-tag',
        'https://cdn.adxensor.com/tag.js',
        [],       // no dependencies
        null,     // no version (CDN handles cache busting)
        false     // load in <head>
    );

    // Add data-ad-client attribute and async to the script tag
    add_filter( 'script_loader_tag', function( $tag, $handle ) {
        if ( 'adxensor-tag' !== $handle ) {
            return $tag;
        }
        return str_replace(
            '<script ',
            '<script async data-ad-client="pub-XXXXXXXX" ',
            $tag
        );
    }, 10, 2 );
}
add_action( 'wp_enqueue_scripts', 'adxensor_enqueue_script' );

Replace pub-XXXXXXXX with your Site ID.

If you prefer not to edit code, use a plugin like Insert Headers and Footers (by WPCode) or Header Footer Code Manager:

Install and activate the plugin

Install and activate the plugin.

Paste the snippet in the Header section

Go to the plugin settings and paste this in the Header section:

<script async
  src="https://cdn.adxensor.com/tag.js"
  data-ad-client="pub-XXXXXXXX">
</script>

Save

Save.

Edit header.php in your theme (wp-content/themes/YOUR-THEME/header.php) and paste the script tag before the closing </head> tag:

<script async
  src="https://cdn.adxensor.com/tag.js"
  data-ad-client="pub-XXXXXXXX">
</script>
</head>

Note: Editing header.php directly will be overwritten when your theme updates. Use a child theme or the functions.php method to avoid losing your changes.

Placing ad slots

Once the script is loaded, place <ins> tags anywhere in your theme or page content.

Theme template file
Block editor (Gutenberg)
Text widget (classic sidebar)

<!-- wp-content/themes/YOUR-THEME/single.php (or any template) -->

<!-- Leaderboard below the site header -->
<ins class="adxensor"
     style="display:block"
     data-ad-slot="header-banner"
     data-ad-format="728x90">
</ins>

Add a Custom HTML block

Add a Custom HTML block where you want the ad.

Paste the snippet

Paste the <ins> snippet:

<ins class="adxensor"
     style="display:block"
     data-ad-slot="in-content"
     data-ad-format="300x250">
</ins>

Open Widgets

Go to Appearance → Widgets.

Add a Custom HTML widget

Add a Custom HTML widget to your sidebar.

Paste the snippet

<ins class="adxensor"
     style="display:block"
     data-ad-slot="sidebar"
     data-ad-format="300x250">
</ins>

Common ad placements

Placement	Slot name suggestion	Recommended format
Below site header	`header-banner`	`728x90`
Above article content	`above-content`	`728x90`
In the middle of an article	`in-content`	`300x250`
Below article content	`below-content`	`728x90`
Sidebar widget	`sidebar`	`300x250` or `300x600`
Mobile sticky footer	`mobile-footer`	`320x50`
Between related posts	`related-posts`	`300x250`

Responsive ads

Use data-ad-format="auto" to let AdXensor automatically pick the best size for the visitor’s device:

<ins class="adxensor"
     style="display:block"
     data-ad-slot="responsive-banner"
     data-ad-format="auto">
</ins>

Auto-sizing rules:

Device	Breakpoint	Chosen format
Mobile	width < 768 px	`320x50` or `300x250`
Tablet	768–1023 px	`468x60` or `300x250`
Desktop	≥ 1024 px	`728x90`, `468x60`, or `300x250`

WooCommerce

AdXensor slots work on WooCommerce pages the same way as regular WordPress pages. Add slots using the Custom HTML block in WooCommerce page templates or use hooks:

// Show a banner above the WooCommerce shop loop
add_action( 'woocommerce_before_shop_loop', function() {
    echo '<ins class="adxensor" style="display:block"
               data-ad-slot="shop-top"
               data-ad-format="728x90"></ins>';
}, 10 );

Verifying the integration

Visit your website

Visit your website in a browser.

Open DevTools and filter by adxensor

Open DevTools → Network and filter by adxensor.

Check the requests

You should see a request to cdn.adxensor.com/tag.js and then to core.adxensor.com/v1/ad.

Confirm in the dashboard

In the AdXensor Publisher Dashboard, go to My Sites → [Your Site] → Statistics and confirm that pageview events appear within a few minutes.

Troubleshooting

Symptom	Solution
Script not loading	Check that `wp_head()` is called in your `header.php` (it should be just before `</head>`)
Slots not filling	Verify your Site ID and that the site status is Active in the dashboard
Plugin conflicts	Some security plugins (Wordfence, iThemes Security) may block external scripts — whitelist `cdn.adxensor.com`
`display:none` on slots	Always include `style="display:block"` on the `<ins>` tag
