Open the automation for the ad you want to add the tag to.
Please note any LEAD ads, for example, buyer, listing, downsize, 12 tips, and custom ads all have individual automations. If you are running a 3 ad split test you will need to add the tag to all 3 of the automations.
To open the automation go to funnels > my funnels > and click edit on the automation that you want to edit.
Click add action
Click the drop-down menu and select "a tag" and then click select
If your desired tag is already created you can select it in the drop-down menu. If you need to create the tag you can click "create new tag" and type in the desired tag. For example, "Buyer," as shown below.
Click "Add Event" - use the hourglass ⏳ on the left side to adjust the time frame. Not necessarily needed for tags unless you want the contact to be tagged a specific tag at a specific time of the automations. You must hover over the automation to reveal the ⏳.
Repeat this process for any other automations.
