What is a good ROAS for a niche e-commerce store on Google Ads?

For this specialist dog e-collar retailer, ~$2,500 in monthly ad spend generated $15,000 in revenue, roughly a 6.4x return. In niche e-commerce, returns like this come from concentrating budget on high-margin, high-intent products rather than advertising the entire catalog.

Should I advertise every product in my e-commerce store?

Not usually. In a small catalog, low-margin accessory items can drain budget without meaningful return. Focusing ad spend on the higher-margin, higher-intent products and deliberately excluding low-return SKUs typically produces far stronger overall ROAS.

Does Google Ads work for niche pet product stores?

Yes. Niche pet categories like dog training e-collars attract specific, high-intent buyers who are actively researching a purchase. A focused Google Ads strategy built around those high-purchase-intent searches can deliver strong returns even with a modest budget.

How much should a small e-commerce store spend on Google Ads?

Budget should match catalog size and margin rather than a fixed figure. This store achieved $15K in revenue on around $2,500 in spend, showing that a modest, well-targeted budget concentrated on the right products can outperform a larger budget spread thinly across everything.

The challenge

This Australian client runs a tightly focused e-commerce store specializing in dog e-collars. It’s a genuinely niche catalog (only around 20–25 products in total), and crucially, not all of them are worth advertising. A handful of the SKUs are low-margin, low-revenue accessory items like e-collar batteries and dog signs, products that would quietly drain ad budget without contributing meaningful return if thrown into a broad Shopping campaign.

This was a build from the ground up rather than a rescue: the brand was first planning to launch paid advertising. The strategic question wasn’t “how do we advertise everything?” It was “which products actually deserve the budget?”

Goals

What we set out to do.

01
Protect ROAS by advertising the right products, not all of them
02
Capture high-purchase-intent dog e-collar shoppers efficiently
03
Apply proven category knowledge to skip the guesswork

The strategy

A Full-Funnel Rebuild, Not Just a Campaign Tweak.

Margin-first product selection

Rather than pushing the entire catalog, spending deliberately concentrated on the e-collar products themselves, the higher-margin, higher-intent items that actually drive profitable revenue. Low-margin accessories (batteries, signs) stayed out of the core advertising push so every dollar of budget worked on products that could deliver a strong return.

In a small catalog, this discipline matters enormously: advertising less, but smarter, is what protects ROAS.

Built for a niche, high-intent buyer

Dog e-collars attract a specific, motivated shopper: dog owners actively researching and ready to buy a training solution. The Google Ads account was structured to capture that high-purchase-intent traffic efficiently rather than chasing broad, top-of-funnel volume that wouldn’t convert in such a specialized category.

Category expertise applied

This isn’t the only client managed in this exact space: paid advertising runs across multiple dog and e-collar e-commerce brands, bringing proven, category-specific knowledge of what sells, how these buyers search, and which products carry the margin to advertise profitably. That cross-account experience shortcut a lot of the guesswork for this brand.

Key takeaway

In niche e-commerce with a small catalog, more products advertised does not mean more revenue. The win here came from margin-first product selection (concentrating budget on the high-intent, high-margin e-collar products and deliberately excluding the low-return accessories) to deliver ~6.4x ROAS. Specialized category experience makes the difference between guessing and knowing which products to back.
