5.3x ROAS scaling a menswear brand profitably on Google Ads.

Blue Island, a premium Indian menswear label, needed to scale Google Ads without cost per order running away. Performance Max — built on clean data and a strong product feed — took them there.

The challenge

Scaling spend without breaking efficiency

Blue Island had product-market fit and a growing catalogue of shirts — but scaling paid acquisition profitably is where most D2C brands stall.

More budget usually means a worse ROAS. The goal was to grow conversions several times over while keeping return on ad spend well above target.

Make Performance Max carry the scale, profitably

Challenges faced

1

Efficiency at scale

Every increase in spend risked driving cost per order up and ROAS down.

2

Catalogue complexity

A wide range of shirts and variants needed the right products shown to the right buyers.

3

Concentrated regional demand

Demand clustered in specific Southern markets that needed prioritising, not blanket spend.

The approach

Performance Max, built on clean data and feed

We rebuilt the account around Performance Max, fed it high-quality conversion data and a strong product feed, and kept optimising it for profit.

Performance Max as the engine

Structured PMax by best-sellers, new customers, and region instead of one catch-all campaign.

5.3x

Blended ROAS

Feed + creative that sells

A clean product feed paired with regional-language video and image assets, so the right shirt met the right buyer.

~6x

Conversion growth

Optimised for profit, not clicks

Tuned bidding and budgets to conversion value, concentrating spend where the return was strongest.

We didn't win by spending more. We won by giving Performance Max cleaner data and a tighter feed than the account had ever had.

What you can learn

How this applies to your business

At scale, data and feed beat budget

Blue Island's growth came from feeding Performance Max clean conversion data and a strong product feed — not from simply spending more. Past a certain point, account quality is what decides ROAS.

Segment Performance Max by intent

Splitting PMax by best-sellers, new customers, and region — instead of one catch-all campaign — let us concentrate budget where return was highest and hold 5.3x while scaling.

Optimise to conversion value, not clicks

Tuning bids and budgets to revenue kept cost per order in check even as conversion volume grew roughly 6x. Feeding the algorithm order value, not just clicks, is what let it scale without margin slipping.
