Google Ads for UK DTC & Online Retailers
Profitable ROAS after VAT and returns — not flattering top-line numbers.
We run Google Ads for UK direct-to-consumer brands, online retailers, and ecommerce operators on Shopify, WooCommerce, and BigCommerce. Our focus is on net-margin-positive ROAS after VAT, returns, and post-Brexit shipping — not the gross revenue figure that hides underperformance.
Why E-commerce Google Ads fail.
VAT and post-Brexit shipping distort ROAS reporting
Google Ads conversion values typically include VAT and exclude returns, shipping, and payment processing. UK ecommerce brands optimising on gross ROAS look profitable on-paper while actually losing money per order. The reported number is not the net economic reality.
Google Merchant Center feeds are the hidden ceiling
Most UK ecommerce accounts run poor-quality feeds — missing GTINs, weak titles, wrong product categories, inconsistent attributes. PMax and Shopping campaigns cannot outperform the feed. Agencies obsess over bidding while ignoring the feed that gates results.
Amazon UK intercepts category search traffic
Amazon UK outbids most brands on category keywords ('running shoes', 'coffee machine'). Amazon's conversion rates on those keywords are often higher than direct-sale sites. UK ecommerce has to be selective about which category terms are worth fighting for vs. where Amazon wins.
E-commerce PPC tactics that actually produce revenue.
Google Merchant Center feed optimisation first
Before any campaign work: clean the feed. Title rewrites with primary keyword in first 70 chars, GTINs populated, custom labels for margin tiers and seasonality, image quality hygiene, correct product categories. This alone typically lifts Shopping and PMax performance 20-40%.
Performance Max with asset group discipline
Run PMax — it works for UK ecommerce — but split asset groups by margin tier, product category, or seasonal relevance. One giant asset group is how accounts lose visibility into what's actually working. Use custom feed labels to power asset group segmentation.
Branded vs non-branded campaign separation
Branded Search ('YourBrand') gets its own campaign with separate budget. Non-branded ('women's trainers') does acquisition work. Mixing them hides non-branded underperformance behind branded campaigns' high ROAS. UK-specific: bid defensively on brand terms against Amazon and eBay listings.
Margin-adjusted conversion values, not VAT-inclusive revenue
Pass contribution-margin values into Google Ads, not order total with VAT. A £120 order with 45% margin contributes £54 of margin, not £120 of revenue. Smart Bidding optimises toward whatever value you pass — send the real number via GA4 Enhanced Ecommerce or Shopify apps.
Customer Match for UK LTV-based bidding
Upload high-LTV customer lists as Customer Match audiences. Bid up for matches to high-value segments, bid down for returns-heavy or discount-only segments. Google cannot see this without your first-party data — UK ecommerce brands running without Customer Match leave compounding efficiency on the table.
How we run E-commerce campaigns.
Week 1: Feed audit + UK unit economics mapping
Audit Google Merchant Center feed for errors, quality issues, and structural gaps. Map actual contribution margin per product category — after VAT, returns, and UK fulfilment costs — so optimisation targets real profit, not reported revenue.
Week 2: Feed optimisation + PMax restructure
Feed cleaned, titles rewritten, GTINs populated, custom labels set. Performance Max asset groups split by margin tier. Branded vs non-branded Search campaigns separated with dedicated budgets.
Week 3: Launch + Customer Match integration
Campaigns live with margin-adjusted conversion values. Customer Match audiences uploaded. First optimisation cycle on day 7 with focus on cross-campaign attribution cleanup.
Month 2+: Scale on new-customer acquisition
Once new-customer data accumulates, shift optimisation from blended ROAS to new-customer acquisition cost. This is how UK DTC brands break the retargeting-is-working illusion and find real growth channels that acquire new buyers at sustainable CAC.
