INTRODUCTION
Modern digital ad campaigns are driven by automation and machine learning; however, optimization can only be as strong as the data collected to inform it.
One of the most powerful tools guiding ad campaign optimizations is Google Tag Manager (GTM), which bridges the gap between marketing strategy and campaign performance.
WHAT IS GOOGLE TAG MANAGER?
Google Tag Manager serves as a control center for website tracking needs. It can collect data such as how many times users click “add to cart,” how far people scroll down a page or how visitors interact with videos. Another benefit of GTM is that you don’t need to contact your web developer or spend hours writing code to track this data.
TURN WEBSITE ACTIONS INTO CONVERSION DATA YOUR CAMPAIGN CAN LEARN FROM
The primary implementation of Google Tags in your ad campaign is tracking conversions. Instead of relying only on page views, adding a conversion tracking tag allows Google Ads to learn which user actions are valuable to your campaign (e.g., filling out a form). This step teaches the model which outcomes matter.
First, determine which actions matter most for your campaign, such as email submissions, bookings, etc. Next, create a “trigger” in Google Ads corresponding to those actions–the trigger fires when the action is completed. Then create a Google Tag connected to your trigger so you receive data when the action occurs. Don’t forget to use Google Tag Manager preview mode to confirm events fire properly.
BUILD HIGH INTENT AUDIENCES FOR YOUR AD CAMPAIGN
Following the campaign lifecycle, the next improvement GTM provides is targeting. Google Tag Manager allows you to track behaviors on your site that can be converted to audience insights and sent to Google Ads and Analytics for remarketing to lookalike audiences. This prioritizes users most likely to take meaningful actions, not just a click. This step teaches the model who is most likely to achieve the outcomes that matter.
Create a Google Ads Remarketing tag in Google Tag Manager and fire it on all pages. Track actions such as scroll depth, video interaction and button clicks. Connect this data to your ad platform, where you will make these actions “audience conditions.”
For example, you should track users who viewed a service but didn’t convert, and target them as engaged prospects. You should also exclude users who have already converted or shown little interest.
FEED IMPROVED BIDDING AND BUDGET SIGNALS TO YOUR AD CAMPAIGN
With conversions and better audiences established, campaigns can further optimize bidding and decision-making. Providing behavioral data gives bidding algorithms a better understanding of engaged prospects and adjusts ad spend accordingly, improving return through data instead of increased budget. This step helps the model learn more quickly and spend efficiently.
Create a hierarchy of actions for your model to learn from by setting up “events” for signs of intent and separating them into primary and secondary conversion actions, such as purchases vs. increased scroll depth. Import tracked events to your ad platform so algorithms can use them. Monitor and adjust events as conversion actions change.
