Meta retargeting
📖 4 min readUpdated 2026-04-19
Retargeting hits people who've already visited your site, engaged with your content, or started a checkout. Cheaper CAC than prospecting, but easy to overdo.
Retargeting audiences
- All website visitors (30 days): broadest retarget
- Cart abandoners: highest intent, highest conversion
- Specific product viewers: intent-matched creative
- Engaged IG/FB users: lower intent but wider reach
- Email subscribers not purchased: owned data retarget
- Past customers (60-180 days): reactivation
Creative for retargeting
Different creative than prospecting:
- Reminder of what they viewed
- Social proof (reviews, testimonials)
- Offers/discounts (if your margin allows)
- Urgency (limited stock, deadline)
- Answers to common objections
Frequency caps
Seeing the same ad 20 times is annoying. Meta auto-caps but consider:
- Shorter retargeting windows (7-14 days instead of 30-60)
- Multiple creative in rotation
- Exclude people who've already converted
Budget allocation
- Prospecting: 70-85% of budget
- Retargeting: 15-30% of budget
Retargeting scales with prospecting. More prospecting = bigger retargeting audience. Don't overspend on retargeting when your audience is small.
The attribution gotcha
Retargeting gets credit for conversions that would have happened anyway. True incrementality of retargeting is smaller than reported. Don't overfund it.
Messenger/WhatsApp retargeting
For certain categories (support-heavy, high-consideration purchases), conversations in Messenger or WhatsApp convert higher than web. Test if applicable.
What to do with this
- Keep retargeting at 15-30% of budget, pushing it higher shrinks your audience and inflates platform ROAS without adding real revenue
- Treat retargeting ROAS as over-claimed by 30-50%, most of those conversions would have happened anyway via organic or email
- Run periodic incrementality tests (pause retargeting for 2 weeks), measure the actual revenue drop, that's your true incremental value
- Segment retargeting by behavior (viewers vs add-to-cart vs initiate checkout), each gets a different ad + offer
- For high-consideration categories, test Messenger/WhatsApp conversational retargeting, can convert 2-3x higher than web retargeting
