How we scaled a global book retailer 300% without breaking ROAS.

Anyone can grow sales if profitability is allowed to slip. Loosen the targets, pour in budget, and revenue climbs while margin quietly disappears. The harder and more useful problem is growing fast while holding the line on efficiency. That was the brief from Awesome Books, and it is the kind of constraint we prefer to work under.

Awesome Books is one of the UK leading online book retailers and a pioneer in sustainable bookselling, processing hundreds of thousands of books a day across an inventory of more than twenty million new titles and five million second-hand books. They wanted to accelerate growth without sacrificing profitability, and to do it across multiple countries at once.

The constraints that shaped the work

• →Strict ROAS and CPA targets that growth could not breach
• →Millions of titles spanning new and second-hand stock
• →A global customer base across several regions and market dynamics
• →A need to capture quick wins while building toward long-term market leadership

Architecture before acceleration

With an inventory that large, the structure of the account matters more than any single tactic. The job was to make sure the right products were surfaced to the right audiences in the right markets, at scale, rather than letting an undifferentiated catalogue compete with itself. That meant disciplined Performance Max and Shopping structure, segmented by theme and value rather than dumped into one campaign, and brand kept separate so reported efficiency reflected real acquisition.

Multi-channel, one set of targets

Growth came from orchestrating Google Shopping, Search, Performance Max, and paid social together rather than treating each as its own silo with its own definition of success. Every channel was held to the same overall efficiency goal, which kept the focus on incremental contribution to the business rather than on whichever platform was best at claiming credit.

Why it held

The growth held because the foundations were built to carry it. Clean structure, separated brand, disciplined campaign governance, and a single shared definition of efficiency meant that scaling spend scaled revenue rather than scaling waste. Fast growth on a shaky foundation reverses the moment you stop pushing. Fast growth on a solid one compounds.

It is the same principle behind everything we do: get the foundations right, hold a single honest measure of success, and let disciplined execution do the rest. The vertical changes from one client to the next. The approach does not.
