There are two ways of installing Cookie-Script in WordPress (or WooCommerce): with a plugin or by modifying template file. Plugin is recommended since you will still be able to update your WordPress theme later.
Method 1: installing Cookie-Script via 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 ediging theme files.
Go to your Cookie-Script.com account and copy your cookie-script code.
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.
