Fomo integrates seamlessly with Google Tag Manager.
Log in to Google Tag Manager and navigate to your website's Workspace, and click Add a new Tag.
Select the 'Tag Configuration' rectangle box, then click 'Custom HTML' on the right side navigation.
Paste the code snippet you're given on the Embed page (while logged into Fomo).
Click 'Save' and you should be asked to create a Trigger. Select 'Add Trigger.'
On the Trigger page, click the default 'All Pages' item in the table. This will take you back to the tag, where you can click 'Save' again.
You're done! Fomo will now fire on whatever pages your Google Tag Manager Workspace is connected to.
If you'd like to disable Fomo on specific pages of your website, no problem. Go here to learn how.
