Each Geo Redirect service you create in our system will come with its own javascript code snippet.
This piece of javascript code needs to be placed into your Magento site only once. It does not need to be updated if any changes are made to the redirect settings.
Steps
On the Admin menu, select System > Configuration
In the panel on the left, under General, select Design
Paste the JavaScript code provided into the Miscellaneous Scripts box
Ensure the code is pasted at the start of the box before any other scripts so it is the first to process
Click on Save Config
