The Challenge

The Starting Point

Fashion is one of the hardest ecommerce categories to make profitable on Google Shopping in Singapore. Shoppers browse many products before buying, compare against marketplaces and fast-fashion giants, and often leave without a purchase. Margins after returns and discounts leave little room, so every dollar of ad spend has to work hard.

This label sold its own womenswear designs through an online store and spent S$8,000 a month on one automated Shopping campaign. It earned S$2.00 for every dollar spent, below the roughly 2.8× it needed to break even after returns. Nearly 40% of its products were disapproved or limited in Merchant Center because of missing sizes, colours and product identifiers, and visitors who browsed without buying never saw the brand again.

What We Did

What We Did

Phase 1, Month 1

Feed Rebuild

We filled in size, colour, material and age group for every product, set product identifiers correctly for the label's own designs and rewrote titles to lead with garment type, fabric and fit.

Shoppers filter by size and colour. A product without those details simply does not show for the searches that matter. Clear titles also improved click-through, because shoppers could see the fabric and fit before they clicked.

Phase 2, Months 1 to 2

Campaign Structure

We split campaigns by category (dresses, workwear and basics) and by margin tier using custom labels, with a separate campaign for bestsellers.

A bestselling dress and a slow-moving basic deserve different budgets. The structure let the account spend where products actually sold. Custom labels also let the team push new arrivals for their first few weeks, when interest in a new collection is highest.

Phase 3, Months 2 to 3

Dynamic Remarketing

We set up dynamic remarketing showing the exact items people had viewed, with a seven-day window for cart abandoners, exclusions for recent buyers and frequency caps.

Fashion shoppers rarely buy on their first visit. Showing them the piece they liked brought many of them back to finish the purchase. Frequency caps and buyer exclusions kept the ads from following people around after they had already purchased.

Phase 4, Months 3 to 5

Bidding and Imagery

We moved to target ROAS bidding by margin tier and tested on-model main images against flat lays, using lifestyle images in remarketing.

On-model images showed fit and drape, which mattered more to shoppers than a clean flat lay. Seasonal edits got their own image sets, so shoppers saw pieces styled for what they were actually shopping for.

Phase 5, Months 4 to 6

Scale With Collections

Once ROAS was well above break-even, we raised budgets around new collection drops, paused sizes that were out of stock and reviewed search terms weekly.

Scaling only made sense once each dollar was profitable. Pausing out-of-stock sizes stopped the account paying for clicks it could not convert. Weekly search term reviews also excluded searches for other brands and marketplaces that brought clicks but rarely sales.

The Results

The Results

By month six, Google Ads returned S$4.10 for every dollar, up from S$2.00. With returns well above break-even, monthly spend grew to S$11,000 and revenue from Google Ads reached S$45,100 a month, 182% more than when the work started. Remarketing brought back shoppers who had left, and nearly every product was eligible to show. Because the account was now profitable at a higher spend, the label could plan larger collection launches with paid support built in from the start, instead of treating Google Ads as a cost to cut whenever sales slowed.

Key Takeaways

What We Learned

Size and colour are not optional for fashion feeds

Shopping filters on size, colour and fit. Filling in those details for every product was the cheapest gain in the whole project, because products that had been invisible started to show.

Fashion shoppers need a second look

Most people browse several times before they buy clothes online. Dynamic remarketing that showed the exact piece they viewed turned many of those browsers into buyers.

Know your break-even ROAS before you scale

This label needed about 2.8× to cover costs and returns. Raising spend at 2.0× would have lost money faster, so the budget only grew once results were comfortably above that line.
