More revenue, triple the ROAS — same ad budget

How we took over a UK art supplies retailer's declining Google Ads account and, on a flat budget, more than tripled both revenue and return on ad spend by bringing it up to date.

Declining revenue and ROAS in a fast-moving category

When we took the account over, revenue and return on ad spend were both in decline. Bromley’s was falling behind competitors who had moved to automated bidding strategies, and it was struggling to keep momentum as Google broadened how ads are matched to searches — with Broad match and Performance Max meaning ads are increasingly triggered by a wider range of queries.

The root of it was an account built for an earlier era of Google Ads. It leaned on a single standard Shopping campaign, carried an unnecessary CPC cap that was throttling visibility on its most important terms, and — for reasons that were never clear — had relevant sub-brand search terms excluded. The product feed was thin, with short titles and no product types, leaving the ads poorly positioned to compete. Meanwhile competitors were adapting to an AI- and Performance Max-led landscape and pulling steadily ahead.

The brief was to bring the account up to date: modernise the structure, fix the feed, and rebuild a search presence so Bromley’s could compete in more auctions — in a category that had become more competitive than ever.

Issues identified

  • Reliant on outdated campaign types
  • Unnecessary CPC cap limiting visibility and traffic
  • Relevant sub-brand search terms excluded
  • Poorly optimised feed — short titles, no product types
  • Competitors pulling ahead with AI-led Performance Max

Bring the account up to date to compete

The account had fallen behind for a simple reason: it was built for an older version of Google Ads. As the platform shifted toward automation and broader query matching, a single Shopping campaign running with a CPC cap and excluded terms was never going to keep pace with competitors who had already made the move. The strategy was to bring the account up to date so it could compete in more auctions — in a landscape more competitive than ever. Three areas of work made that happen.

Modern structure and Performance Max. We rebuilt the campaign structure into something more refined and responsive, able to lean into seasonal performance shifts rather than running flat all year, and introduced Performance Max with segmented asset groups so search themes and audience signals could be tailored rather than treated as one undifferentiated block.

A competitive product feed. The feed was the account’s weakest asset and its biggest opportunity. We optimised it end to end — richer product titles, proper product types and a range of other attributes — so the ads were positioned to win more of the auctions they entered.

Brand and sub-brand search presence. We removed the CPC cap that had been throttling the main brand terms and gave them a dedicated, properly funded brand search campaign, then built new search campaigns around the sub-brand terms that had previously been excluded — reclaiming a search presence the account had been giving away.

How we did it

Pillar 01

Modern structure & Performance Max

We rebuilt the campaign structure into a more refined setup that could respond to seasonal performance shifts rather than running flat across the year. Performance Max was introduced with segmented asset groups, so search themes and audience signals could be tailored to different parts of the range instead of being treated as one undifferentiated block. Promotional assets were added on top to push awareness of offers and sales — bringing the account in line with the automated, asset-led approach competitors were already using.

Pillar 02

Product feed optimisation

The product feed had been actively holding the account back — short titles, no product types and little supporting detail left the ads poorly positioned in Shopping and Performance Max auctions. We rebuilt it end to end, writing richer product titles, adding proper product types and improving a range of other attributes, so each product was far better matched to the searches it should have been competing for. A stronger feed meant the same budget could win better-quality auctions.

Pillar 03

Brand & sub-brand search presence

The old setup had capped CPCs on the main brand terms and excluded relevant sub-brand terms entirely, handing competitors an easy route to Bromley's own audience. We removed the CPC cap and gave the main brand a dedicated, properly funded search campaign to protect it, then launched new search campaigns targeting the previously excluded sub-brand terms — rebuilding a search presence the account had been giving away.

Across the engagement — from September 2024 to May 2026 — the account turned around completely. Revenue more than tripled, return on ad spend more than tripled, and cost per acquisition was nearly halved — all on a monthly budget that barely moved. From an account losing ground to competitors, Bromley's now competes from a position of strength.

Monthly revenue across the engagement. Exact figures are held back, but the shape tells the story — a modest September 2024 starting point building into a consistently higher band through 2025 and 2026, all without increasing the monthly budget.

Blended return on ad spend by period. The 2024 figure is the baseline across the months before we took the account over; 2025 is the first full year under the new structure; 2026 covers January to May. Return on every pound of spend climbed from roughly 8x to more than 28x and held there — efficiency that proved durable rather than a one-month spike.
