Are You Falling for “Best Practice Bias” on Paid Social?
Many media buyers in 2025 question whether audience targeting still works.
Tanner Duncan & Zach Nussbaumer shared their tactical insights with us below.
The current status quo is to stick to broad or let ASC+ do it's thing... and yes that "can" work but you can also eat cereal with water.
But you shouldn't...
Sure, broad can work. But when did we start blindly following what Meta tells us without testing for ourselves?
If you’re putting 100% of your budget into a single broad-based strategy just because it’s the flavor of the day, you’re leaving money on the table.
Here’s why audience targeting still matters—and how to test it effectively:
1) Interest-Based Audiences
A great way to reach people who should love your brand but haven’t discovered it yet.
- Directly Related: If you sell skincare, target beauty brands, influencers, and skincare enthusiasts.
- Tangentially Related: Think lifestyle—Lululemon, Whole Foods, SoulCycle, high-end travel.
Quick Test:
- 3–5 ad sets (CBO)
- Each ad set targets a category (beauty, fitness, travel, etc.)
- Budget = 7 purchases/day per ad set (7 x CPA x # of ad sets)
- Use top 5–7 high-performing Post IDs from the last 14 days
2) Lookalike (LAL) Audiences
LALs aren’t dead. You just need the right seed + LAL percentage.
Try these:
Value-based (people similar to your highest-value customers)
Pixel-based (people similar to all customers)
Social (FB/IG engagers, video viewers)
Klaviyo (email subs, past buyers)
Quick Test:
- 3–5 ad sets (CBO)
- Each ad set = different LAL seed (value, pixel, social, etc.)
- Budget = 7 purchases/day per ad set (7 x CPA x # of ad sets)
- Test 10% LALs (broader = better for larger spenders)
3) Proxima AI Audiences (shameless plug)
If LALs are gas, Proxima is rocket fuel.
They analyze $20B+ in Shopify purchases to build AI-powered lookalikes. The result? Smarter audience targeting beyond broad.
Example: Pestie scaled $6M in incremental ad spend while maintaining CAC with AI Audiences.
4) Retargeting Audiences
Yes, retargeting is weaker post-iOS14. But it still works if structured correctly.
Quick Test:
- L365 (Long Window): Anyone who engaged with your brand in the last year
- L30 (Recent Window): Hot leads from the last 30 days
- Don’t over-segment. Bigger audiences = more optimization power.
TL;DR:
- Broad & ASC work, but don’t ignore audience targeting
- Interest-based + LALs still drive scale if tested properly
- AI Audiences take it a step further
- Retargeting isn’t dead—just needs a better setup
Your audience strategy should fuel your brand’s growth, not just follow the latest trends.
