Retargeting for Growth Marketers
DIRECT ANSWER
Retargeting (also called remarketing) is the practice of serving targeted ads to people who have previously interacted with your brand — visited your site, watched a video, or appeared in your CRM — using pixel-based tracking or uploaded audience lists. Because these audiences have already expressed intent, retargeting consistently delivers lower cost-per-conversion than cold prospecting campaigns. For Growth Marketers, this is especially relevant because running high-frequency experiments across channels without a team to execute each one.
What retargeting means for Growth Marketers
Growth marketers live in experiment cycles — hypothesis, test, measure, iterate. The constraint is always execution velocity: not enough hours to run the tests fast enough to find the winners. Growth stalls when the test queue backs up.
For a growth marketer, retargeting is a lever you need but rarely have time to execute consistently. Pixel-based retargeting places a small snippet of JavaScript on your site that drops a browser cookie when a visitor lands. Ad platforms (Meta, Google, LinkedIn, and others) match those cookies to users in their network and serve them ads. List-based retargeting — also called Customer Match or Custom Audiences depending on the platform — works differently: you upload a hashed list of emails or phone numbers, the platform matches them to its own user base, and you target that matched audience. List-based retargeting is less dependent on third-party cookies and is therefore more durable as cookie deprecation continues.

FAQ
Retargeting for Growth Marketers — common questions
What's the difference between retargeting and remarketing?
The terms are often used interchangeably. In Google's ecosystem, 'remarketing' historically referred to showing display or search ads to past visitors, while 'retargeting' became the broader industry term covering any platform. The functional distinction that does matter: pixel-based retargeting targets anonymous cookie pools; list-based remarketing targets known contacts from your CRM. The latter is more privacy-resilient and typically converts at higher rates because the audience is better defined.
How does retargeting fit into how Growth Marketers work?
Growth Marketers are running high-frequency experiments across channels without a team to execute each one. Retargeting is exactly the kind of work that suffers under that constraint — it needs consistent execution that a stretched team can't sustain manually. Hadrian closes that gap autonomously.
