There are two ways of installing Cookie-Script in WordPress (or WooCommerce): with a plugin or by modifying a template file. The plugin is recommended since you will still be able to update your WordPress theme later.
Method 1: installing Cookie-Script via the WordPress plugin.
To make your job with Cookie-Script snippet easier and more enjoyable we have created a WordPress plugin. All you need to do is install and follow instructions:
1 Download plugin from https://wordpress.org/plugins/cookie-script-com/ or find it in your WordPress dashboard: click on Plugins > Add New. Then type your “Cookie-Script.com” into the search box on the top right and then click Install Now
2 Go to the Plugins Search “Cookie-Script” and click Activate
3 Go to the Plugins again and click Settings under “Cookie-Script.com”
4 Finally, you have to copy-paste Item ID from your Cookie-Script.com account. Do not forget to pick Script Type (HTTP,HTTPS or HTTPS + GEO Targeting)
Method 2: installing Cookie-Script for WordPress by editing theme files.
Log in to your WordPress Admin Dashboard.
Hover Appearance and click to the Theme Editor
Find and click on the header.php template file
Paste copied Cookie-Script snippet just before the </head> closing tag.
Click the Update File button.
Cookie-Script is installed on WordPress now and should be ready for use.
