ROAS by Channel: 2026 Benchmarks

The old "4:1 is good ROAS" rule of thumb is dead - blended ROAS has eroded to roughly 2.87:1 in 2026 as competition and attribution gaps both worsen. Here's what good actually looks like, channel by channel, and why the benchmark matters less than your own break-even number.

The 2026 numbers, by channel

Why the blended average keeps dropping

Two forces, both structural rather than cyclical: rising customer acquisition costs across nearly every paid channel, and worsening attribution - privacy changes and platform walled gardens make it harder to credit the right channel for a conversion in the first place. A campaign that's actually performing fine can look worse than it is simply because more of its real return isn't being measured.

ROAS is not profit - the number that actually matters

A 4:1 ROAS at 20% gross margin means you spent $1 to generate $4 in revenue and $0.80 in gross profit - not $4 in profit. Before comparing yourself to any industry benchmark, calculate your own break-even ROAS:

Break-even ROAS = 1 / gross margin

At a 40% margin, break-even is 2.5:1. At a 20% margin, it's 5:1. The same "3:1 ROAS" is comfortably profitable for one brand and a loss-leader for another, depending entirely on margin structure - which is why industry benchmark tables are a starting reference point, not a target to hit.

The channel nobody's benchmarking yet: AI-referred traffic

Every channel in the table above has a decade or more of benchmark data behind it. AI-referred traffic - from ChatGPT, Gemini, Perplexity, and Amazon Rufus - doesn't, for a structural reason: most of it isn't being measured at all. AI surfaces strip referrer headers on outbound clicks, so Google Analytics buckets that traffic as "Direct" instead of attributing it to the AI surface that actually sent the shopper. We've written up the mechanics of this in detail in Dark Agentic Commerce Traffic - the short version is that a brand's real AI-driven ROAS is very likely better than its dashboard shows, because the dashboard can't see most of the channel yet.

That matters for this benchmark table specifically: if you're comparing your Google, Meta, and TikTok ROAS against 2026 norms but have no equivalent number for AI-referred traffic, you're optimizing three-quarters of a five-channel picture. Fixing that measurement gap - not just chasing a higher ROAS on the channels you can already see - is usually the highest-leverage move available before adding more paid spend anywhere.
