Audiences & targeting
What is Retargeting?
Retargeting (also called remarketing) is showing ads to people who have already interacted with your business — website visitors, video viewers, add-to-cart users — instead of a cold audience seeing you for the first time. These warm audiences are built from pixel data or Meta engagement.
Example
Someone adds a product to cart but doesn't check out. A retargeting ad shows them that exact product a day later. Because the audience already has intent, retargeting typically delivers a higher conversion rate and ROAS, and a lower CPA, than cold prospecting.
Why it matters
Warm audiences convert more cheaply than cold ones, so retargeting is usually the most efficient spend in the account — but the audiences are small, so they can't scale a business on their own and they fatigue fast. It's a closer, not a growth engine.
How to use and improve it
Segment by intent (product viewers vs cart abandoners vs past buyers), exclude people who already purchased, cap frequency so you don't burn the small pool, and rotate creative regularly.
Frequently asked questions
What's the difference between retargeting and remarketing?
In practice they mean the same thing — re-engaging people who already know you. 'Remarketing' is the older term; 'retargeting' is more common for paid social ads.
Do I need the Meta Pixel for retargeting?
For website-based retargeting, yes — the pixel (ideally with the Conversions API) records visitor actions so you can build the audience. You can also retarget from Meta-native engagement like video views without a pixel.
Why is my retargeting audience so small?
Retargeting pools only contain people who already interacted with you, so they're naturally limited. That's why frequency climbs quickly and why retargeting alone can't scale spend.
