Catalog ROAS vs campaign ROAS: why they never match (and which one to trust)
Catalog ROAS and campaign-level ROAS almost never match, and that is expected, not a bug in your reporting. Retargeting DPA campaigns typically return 2.5x to 6x ROAS because they recapture people who already visited your site. Cold DABA prospecting lands around 1.2x to 2.5x because it is finding buyers who have never heard of you.1 Judging both against one blended target is the actual mistake, not the gap between them.
Why catalog ads report such different numbers
Dynamic Product Ads (DPA) and Dynamic Ads for Broad Audiences (DABA) get conflated because they run through the same catalog, but they solve different problems. DPA retargets people who already visited your site, browsed products, or abandoned a cart, and brings them back with the exact items they looked at. DABA prospects people who have never been to your site, using Meta's behavioural signal instead of pixel history to guess who might buy.1
Those are structurally different audiences, so they produce structurally different ROAS. A cart abandoner already knows your brand and was close to buying, which is why DPA retargeting can post 2.5x to 6x. A cold prospect has never heard of you; landing anywhere in the 1.2x to 2.5x range there means the campaign is working.
If you are pausing or fixing a prospecting campaign because it cannot touch your retargeting ROAS, you are solving the wrong problem. Split reporting by campaign type first, DPA retargeting vs DABA prospecting, before you decide anything is underperforming.
The comparison, side by side
| Campaign type | Typical ROAS | Who it reaches | What high ROAS actually proves |
|---|---|---|---|
| DPA retargeting | 2.5x to 6x | People who already viewed your site or cart | You recapture warm intent well, not that you can find new buyers |
| DABA prospecting | 1.2x to 2.5x | People who have never visited your site | You generate real new demand; a lower ratio is expected |
| Blended MER | 3x to 5x+ target | All channels, all revenue | Whether total marketing spend pays for itself, halo effects included |
Why a single blended number (MER) matters more than either
Once retargeting and prospecting are separated, the next question is which number to report up. The answer is neither in isolation. It is Marketing Efficiency Ratio (MER), sometimes called blended ROAS: total revenue divided by total marketing spend across every channel, not just Meta.2
MER matters because platform-reported ROAS only counts what its own pixel or catalog can see. In one illustrative example, a DTC brand running paid search, paid social, and influencers sees 2.0 ROAS in Meta Ads Manager, but MER across all channels comes out at 3.5, because paid social was driving halo effects in organic and email sales that platform ROAS could not see.2 Catalog ROAS has the same blind spot: it is real, but it is not the whole picture.
A good blended MER benchmark is often cited around 5.0 or higher, meaning $5 in total revenue for every $1 of marketing. The right target varies by margin, growth stage, and how much revenue is organic versus paid.2
How to use these numbers together
- Split Meta reporting by campaign type first. Do not read "Meta ROAS" as one number. Separate DPA retargeting from DABA prospecting before drawing conclusions.
- Set separate benchmarks for each. Roughly 2.5x to 6x for retargeting and 1.2x to 2.5x for cold prospecting. A prospecting campaign at 1.8x is not broken; it is in range.
- Track MER monthly, not just campaign ROAS. MER tells you whether the whole system, including halo effects, is profitable.
- Use ROAS to optimise, MER to decide. ROAS tells you which campaign, audience, or creative to adjust. MER tells you whether to grow, hold, or cut the budget overall.

FAQ
Why is my catalog retargeting ROAS so much higher than my prospecting ROAS?
Because they reach different people. DPA retargeting shows ads to people who already visited your site, viewed products, or abandoned a cart, which typically returns 2.5x to 6x ROAS. DABA prospecting reaches people who have never heard of you and typically lands at 1.2x to 2.5x. The gap is structural, not a sign either campaign is broken.
Should I judge DPA retargeting and DABA prospecting against the same ROAS target?
No. One blended target guarantees you either kill a healthy prospecting campaign too early or under-invest in a retargeting campaign that is actually performing. Set separate benchmarks: roughly 2.5x to 6x for retargeting and 1.2x to 2.5x for cold prospecting.
What is MER and how is it different from ROAS?
MER (Marketing Efficiency Ratio, also called blended ROAS) is total revenue divided by total marketing spend across every channel. ROAS measures return at the campaign or channel level. ROAS tells you which campaign to optimise; MER tells you whether marketing spend is making the business more profitable overall, including halo effects ROAS cannot see.
