Facebook Ads targeting in 2026 has shifted from manual interest stacks toward broad targeting plus AI, because Meta’s algorithm now finds buyers better with less input than with rigid interest lists.

Key takeaways

Broad vs interest targeting
| Approach | How it works | 2026 verdict |
|---|---|---|
| Interest stacks | Manual interest lists | Weakened, still useful for niche |
| Broad + AI | Let Meta find buyers | Default for most |
| Custom audiences | Your own data | Retargeting, lookalikes |
| Lookalikes | Modeled from your customers | Strong prospecting |
The shift is real: Meta’s AI now outperforms manual interest targeting in most accounts, so the manual stacks are a smaller part of the playbook.
Custom audiences and lookalikes
Your own data — website visitors, customer lists, and engagers — remains the most reliable signal you control. Use it for retargeting and to build lookalike audiences that model new prospects on your best customers.
“The best targeting data is the data you already own. Feed Meta your real customers, and it will find you more of them.” — Priya Sharma, AdsMG AI
