Is Facebook still worth it in 2026? Real data by niche

"Facebook died" became a 2022 cliche that still shows up in new-client calls in 2026. It did not die — but it changed so much that recommending Facebook the old way is throwing money away.

Here is the honest analysis: in which niches Facebook still delivers ROI in 2026, in which it is not worth the investment, and what changed operationally.

The current state of Facebook

Comscore + Datareportal data from Q1 2026:

• 116 million monthly active users in Brazil.
• Average age: 38 years (up 4 years since 2022).
• Average daily time: 28 minutes (down 35% since 2022).
• 62% of time on Reels + Stories, only 12% on the classic feed.

Summary: fewer people spending less time, but still a massive audience — and older, with more purchasing power.

Niches where Facebook still delivers

1. Health and wellness (target 40+)

Average Facebook Ads ROAS in 2026: 3.8. Mature audience buys health plans, supplements, medical consultations. CPM cheaper than Instagram.

2. Real estate

Real estate lead via Facebook costs 35% less than via Instagram. Works mainly in capitals and inland areas. The purchase decision-maker (40+) is still there.

3. Adult education

Courses for 35+ (specialization, MBA, graduate) have CPL on Facebook around R$ 18 vs R$ 32 on Instagram.

4. Local marketplaces

"Buy-sell-trade" groups remain massive. For a local client (auto shop, pet store, neighborhood restaurant), city groups deliver free visibility.

5. Religion and family

Engagement on religious and family content remains very high on Facebook. Churches, communities, family events benefit.

6. Politics and mobilization

Facebook is still the dominant political mobilization channel — organic reach in party groups is absurd.

Niches where it is no longer worth it

1. Fashion and beauty for 18-30

Audience migrated to Instagram and TikTok. Average ROAS dropped to 1.4 — below break-even.

2. Tech and B2B startup

Decision-maker moved to LinkedIn. Facebook B2B CPL rose 280% in the last 3 years.

3. Viral / entertainment content

Organic reach plunged. A page with 200k followers averages 2k views per post.

4. Influencer / creator

The feed algorithm prioritizes Reels — almost no one sees influencer posts in the classic feed.

Organic reach in 2026

An average commercial page delivers 1.8% organic reach per post (was 16% in 2014). Translation: posting without investing in media is practically irrelevant.

The exception is Reels. Facebook Reels still has strong distribution outside the base — average organic reach is 3.2x the page's follower count.

Facebook Reels: the underused asset

In 2026, Reels on Facebook delivers mass cold reach especially in 35+. Cost: zero. The same Reel from Instagram can be reposted on Facebook in 2 clicks (via Cross-posting).

Recommendation for any client: repost 100% of Instagram Reels on Facebook. Costs nothing and gains on average 30-50% additional reach.

Facebook Ads in 2026

Still the most sophisticated media tool on the market. Detailed audiences, lookalike, retargeting, catalog. CPM 30-50% cheaper than Instagram depending on niche.

Recommended stack for any client with more than R$ 5k/month of budget:

1. Advantage+ Shopping (e-commerce) or Advantage+ Leads (B2B/service).
2. Site visitor retargeting (30d window).
3. 1% lookalike of buyers.
4. Placements: Reels + Feed + Stories (all selected, let the algorithm decide).

What to cut in 2026

• Solo photo feed posts: zero return.
• Link posts with text: minimal reach.
• Custom page tabs: nobody opens.
• Facebook Events (except for religious/political communities).

How to decide if it is worth it for the client

Ask:

1. Is the target audience 35+?
2. Is the ticket mid/high?
3. Does the purchase decision require trust?
4. Does the client have an old email base (4+ years)?

If you answered yes to 3 of 4, keep Facebook in the strategy (with focus on Reels + Ads). Otherwise, focus on Instagram and TikTok.

How to manage Facebook in the same routine

Mais Social schedules Facebook alongside Instagram, TikTok, LinkedIn and Reels — you post a Reel once and it goes to the selected platforms at the same time, without manually reposting.

Conclusion

Facebook in 2026 is not "every client" — it is "the right client". 35+ audience, mid/high ticket, content in Reels and well-segmented Ads. For that profile, it still delivers competitive ROAS. For young fashion and B2B tech, skip it.
