Retargeting in Paid Media
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. In Paid Media specifically, this means Pull daily spend, CPC, CTR, and ROAS by campaign and ad set across all platforms and Detect underperforming ad sets (ROAS below threshold) and pause or reallocate budget — all of which Hadrian's Paid Media Agent executes autonomously on your live data.
What retargeting means in Paid Media
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.
For Paid Media teams, retargeting is a lever that needs consistent execution. The Paid Media Agent reads Google Ads API (campaigns, ad groups, search terms, conversions), Meta Ads API (ad sets, creative performance, audience overlap), LinkedIn Ads API (campaign groups, sponsored content metrics) and applies retargeting across: Pull daily spend, CPC, CTR, and ROAS by campaign and ad set across all platforms; Detect underperforming ad sets (ROAS below threshold) and pause or reallocate budget; Generate ad copy variants using winning creative patterns and queue for approval; Manage negative keyword lists in Google Ads based on search term reports; Produce weekly budget pacing report: projected end-of-month spend vs budget; Run audience overlap analysis and recommend audience exclusions to reduce waste.

FAQ
Retargeting in Paid Media — 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 latter is more privacy-resilient and typically converts at higher rates because the audience is better defined.
