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 This method adds the AdXensor script tag to every page of your site via `wp_enqueue_scripts`. 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 ``` ```php theme={null} ); // 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( ' ``` Save. Edit `header.php` in your theme (`wp-content/themes/YOUR-THEME/header.php`) and paste the script tag before the closing `` tag: ```html theme={null} ``` **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 `` tags anywhere in your theme or page content. ```php theme={null} ``` Add a **Custom HTML** block where you want the ad. Paste the `` snippet: ```html theme={null} ``` Go to **Appearance → Widgets**. Add a **Custom HTML** widget to your sidebar. ```html theme={null} ``` ## 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: ```html theme={null} ``` 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: ```php theme={null} // Show a banner above the WooCommerce shop loop add_action( 'woocommerce_before_shop_loop', function() { echo ''; }, 10 ); ``` ## Verifying the integration Visit your website in a browser. Open **DevTools → Network** and filter by `adxensor`. You should see a request to `cdn.adxensor.com/tag.js` and then to `core.adxensor.com/v1/ad`. 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 ``) | | 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 `` tag | → [Full troubleshooting guide](/publishers/support/troubleshooting)
