Each Geo Popup service you create will come with its own JavaScript code.
This piece of JavaScript code needs to be placed in your Wordpress website's footer.
Steps:
Click on Appearance
Click on Editor
Find and click on Footer (footer.php)
Find the closing body </body> in the editor (it should be in the end of the file)
Paste the code above the </body> tag
Save
Alternatively you can use a third-party Header and Footer code plugin and add our code to the Footer.
