Broad audience scaling in 2026

Quick Answer

Broad targeting in 2026 isn't 'untargeted' — it's deliberately signal-rich. Meta's algorithm has improved enough that telling it less about who to target produces better results than constraining it. The accounts winning at scale run broad targeting (only age and country specified) and let creative do the audience-selection work. The exceptions are narrow B2B, regional services, and luxury — where the audience is genuinely small and broad would waste budget.

The Framework

1. The new definition of 'broad'

Country + age range (often 18-65+) + language. Nothing else. No interests, no behaviours, no detailed targeting expansion (because there's nothing to expand from). Strip everything that isn't essential.

2. Let the creative target

When audience is broad, creative does the targeting. A video that opens with 'For runners who hate knee pain' will only convert runners with knee pain, regardless of who Meta shows it to. The creative is the filter.

3. Cold conversion event matters more than ever

Optimise for purchase, not pageview, on broad campaigns. The pixel uses your conversion event as the prediction signal — give it the strongest signal possible.

4. Bigger budgets feed broad better

Broad needs scale to find pockets. $100/day on broad is too little — it can't escape learning. $500+/day per ad set on broad is the working minimum at most accounts.

5. Run broad in dedicated CBO campaigns

Don't mix broad with narrow audiences in the same campaign. They have different bid dynamics and the narrow ones will starve the broad ones (or vice versa). Separate CBO campaigns work best.

6. The exceptions where narrow still wins

Genuinely narrow audiences: B2B with small TAMs, regional services (a plumber in Bristol), luxury brands targeting top-1% income. In these cases, narrow targeting is necessary because broad will waste budget on people who can never buy.

Real Numbers from the Field

A fitness apparel brand we audited had been running 14 ad sets with detailed interest targeting. We collapsed to 2 ad sets — one broad CBO and one 1% LAL CBO — both at country-only targeting. Within 6 weeks, blended ROAS improved 22% and CPMs dropped 15% because Meta could optimise across the full audience instead of fighting their interest constraints.

Frequently Asked Questions

Won't broad targeting waste budget on the wrong people?

It would in 2018. In 2026, Meta's prediction model is good enough to find converters within broad targeting. Your creative tells Meta who to find.

Should I exclude existing customers from broad?

Yes, especially for prospecting campaigns. Add existing customers to a custom audience and exclude them from prospecting. Keep them in retargeting campaigns instead.

Does broad work for B2B?

Sometimes. Broad works for B2B SaaS targeting wide professional audiences. Doesn't work for niche enterprise sales where the buyer pool is genuinely tiny.

Can I add 'detailed targeting expansion' to a narrow audience?

Yes, and Meta now defaults to it. It's a half-measure between narrow and broad. If your goal is broad, just go broad — don't pretend with expansion settings.

How big should my broad audience be?

For a country-level campaign, the audience size will be tens of millions. That's fine. Bigger isn't a problem — it's the point.

Stop Guessing What Your Ads Look Like at Scale

When you're spending £5k+ a day, you can't manually screenshot every ad on every device, in every placement, in every locale. Things break silently. Creators ship the wrong aspect ratio. Localised text overflows. Safe zones get clipped by Reels UI.
