How to Track New-to-Brand on Instacart

The short answer is that NTB should be read as an acquisition signal, not a vanity metric. If your Instacart account shows strong total ROAS but a very small amount of New-to-Brand activity, the program may be capturing shoppers who already know you instead of helping the brand grow.

That does not automatically mean low NTB is bad. Some campaigns are meant to defend high-intent demand. The point is to understand the balance. A healthy Instacart program usually needs both efficiency and enough new shopper reach to keep the brand moving forward.

What New-to-Brand Actually Tells You

NTB helps answer a simple question: are your ads converting shoppers who are new to your brand, or mostly converting people who were likely to buy anyway? For founder-led CPG brands, that distinction matters because the media budget is usually limited. Every dollar needs a job.

If most attributed performance is coming from repeat shoppers, the account can look better than it really is from a growth standpoint. If NTB is present but extremely expensive, the program may be buying growth that does not hold up financially. The useful answer is usually in the balance between those two extremes.

Why NTB Matters for Founder-Led CPG Brands

Lean CPG teams do not just need dashboard performance. They need evidence that spend is building the business. NTB matters because it helps show whether Instacart is helping the brand reach new households instead of only converting repeat basket behavior.

This is especially important when a brand is trying to expand retail distribution, support launches, or improve the mix between defending existing demand and acquiring new customers. NTB is not the whole answer, but it is one of the clearest ways to see whether the growth engine is broadening or staying narrow.

How To Read NTB in Instacart Ads Manager

Start with campaign-level reporting in Instacart Ads Manager. Turn on the New-to-Brand fields you want to review, then compare those values against total spend, total attributed sales, and total ROAS for the same time period.

1. Review NTB results at the same level where budget decisions are made.
2. Compare NTB sales or orders against total campaign output.
3. Check whether the campaigns with the most NTB are still efficient enough to keep funding.
4. Look for patterns by product group, placement, or retailer context.
5. Use weekly trends, not one isolated day, to decide whether acquisition quality is improving.

In practice, the goal is not to maximize NTB blindly. The goal is to see which campaigns are creating enough new customer value to deserve more budget without dragging down the full program.

How NTB Fits With ROAS and Blended ROAS

NTB should sit next to ROAS, not replace it. ROAS tells you whether the media is efficient. NTB tells you whether that efficiency is coming from new shoppers or from existing demand. Blended ROAS then shows whether the full media system is healthy across Instacart, Meta, and Google.

If you need the cross-channel measurement framework behind that view, read our guide on how to measure blended ROAS across Instacart, Meta, and Google. If you need a benchmark context for what efficiency should look like, pair this with what a good Instacart ROAS looks like for CPG brands.

Common NTB Reading Mistakes

1. Treating NTB as the only metric that matters.
2. Judging NTB without checking whether acquisition spend is still efficient.
3. Comparing different date ranges between NTB, spend, and total sales.
4. Assuming a high ROAS campaign is healthy without checking whether it is mostly repeat demand.
5. Making decisions from one short spike instead of a weekly pattern.

Most NTB confusion comes from reading the metric without business context. The number becomes useful when it helps answer a budget question, not when it sits by itself in a dashboard export.

A Practical Example

A frozen CPG brand is a useful example of why NTB belongs in the weekly operating view. Grocer Folk did not treat acquisition in isolation. We looked at campaign structure, spend discipline, blended reporting, and whether the media mix was helping the brand grow instead of just defend demand.

That broader operating model helped move the brand to 4x+ blended ROAS. Read the full case study here: How Grocer Folk helped a CPG brand grow blended ROAS to 4x+.
