E-commerce agencies.

Ecommerce marketing is the discipline of acquiring, converting and retaining customers for brands selling direct through Shopify, WooCommerce, Magento, BigCommerce or custom storefronts. It is distinct because LTV-to-CAC maths drive every decision, the post-iOS attribution gap forced a measurement rebuild, and the DMCC Act now polices drip pricing and was-now claims with fines of up to 10% of global turnover.

Editor's note
AgencyIndex lists 16 UK agencies positioning themselves as core ecommerce, alongside a much larger pool that takes on ecommerce work as part of broader retail, DTC or performance briefs (see also the Fashion-Retail and Health-Beauty industries). The 16 split into four working shapes: Shopify Plus partners and headless-commerce build-and-grow shops, conversion and CRO specialists, performance-media-only teams running Meta, Google and TikTok at scale, and full-stack ecommerce growth agencies that hold acquisition, lifecycle and analytics on a single retainer. The sector is distinct for four reasons. The LTV-to-CAC ratio is the religion: Shopify itself flags 3:1 as the working floor for a sustainable book, with premium DTC brands targeting 4:1 to 6:1, and most decisions about media mix and creative cadence come back to that number. The post-iOS 14.5 attribution gap forced a rebuild of measurement: browser-pixel coverage collapsed, Meta CAPI and server-side tracking became table stakes, and high-volume brands shifted from platform-reported ROAS to Marketing Efficiency Ratio (total revenue divided by total ad spend) to read truth out of the noise. The Digital Markets, Competition and Consumers Act 2024 came into force on 6 April 2025, banning drip pricing and tightening was-now claims, with the CMA opening its first eight investigations and issuing advisory letters to a further 100 businesses on 18 November 2025. And the maths behind ROAS only works once returns are priced in: fashion ecommerce return rates of 25-40% can turn a 4.0 gross ROAS into a 2.8 net ROAS, before reverse-logistics costs. What is shifting in 2026 is the demand side as well as the measurement side. Retail media networks (Tesco Media, Nectar360, Boots Media Group, Amazon Ads) grew 22.7% year-on-year in 2024 and are forecast above £4bn of UK spend in 2025, drawing budget out of paid social. Google AI Overviews now appear on roughly a quarter of all searches and have cut organic CTR on affected queries by around 60%, pushing GEO and AEO into the SEO scope of work even for transactional product queries. Shopify Plus headless builds are reshaping the stack, with all-in costs landing in the £7,500-£15,000 a month range for a brand at £2m revenue once apps, agency retainer and observability are stacked. Subscription and replenishment mechanics, retention CRM and zero-party data capture are doing more of the work that Meta retargeting used to do.

Regulatory landscape
CMA · ASA · DMCC Act · ICO
drip pricing and was-now rules now govern every product page

The Digital Markets, Competition and Consumers Act 2024 came into force on 6 April 2025 and rewired the rules. Drip pricing is now banned: total cost including all mandatory fees must be shown at the earliest stage pricing is displayed, with shared liability extending to marketplaces, price-comparison sites and influencers, not just the seller. The CMA can fine up to 10% of global turnover for the most serious breaches and has powers to enforce against overseas traders that target UK consumers. On 18 November 2025 the CMA published its final price transparency guidance, opened its first eight DMCC Act investigations into drip pricing, time-limited offers and default opt-ins, and issued advisory letters to 100 further businesses across sectors including fashion, homeware, and online vouchers. The ASA polices ad-claim accuracy under the CAP Code, with active 2025 rulings against inflated was-now percentages, mystery-box discount maths, and crossed-out reference prices not actually available at booking. The ICO enforces UK GDPR and PECR over data capture, consent and electronic marketing, which sits over every email and SMS lifecycle programme. Fake-review rules under CAP 3.44-3.46 require labelling of incentivised reviews and prohibit suppression of negative ones.

Specialist signals
5 signals
of real ecommerce experience
  • · Platform fluency on Shopify Plus, Magento, BigCommerce or headless, with named launches and a working view on apps, observability and the all-in monthly cost of ownership
  • · Contribution-margin and LTV-to-CAC discipline baked into reporting, not just platform-reported ROAS, with Marketing Efficiency Ratio (MER) as a standard read for high-volume accounts
  • · Post-iOS attribution literacy: Meta CAPI deployed with deduped pixel pairing, server-side GA4, first-party identifiers in events, and an honest view on what platform data can and cannot show
  • · DMCC-Act-aware pricing copy and product-page audit workflow, with a documented process for total-cost display, was-now substantiation and CAP-compliant review handling
  • · CRO discipline with a running test calendar, evidence on hypothesis-to-win rate, and a returns-and-margin-aware ROAS framework that does not pretend a 4.0 gross is a 4.0 net
Sector watch-outs
5 to watch
in any ecommerce pitch
  • · ROAS reported without contribution-margin maths, no returns adjustment, and no MER alongside the platform numbers, especially in fashion and beauty where return rates routinely sit above 25%
  • · Was-now and time-limited-offer copy in the work samples that will not clear the DMCC Act or the CAP Code, with no mention of the 18 November 2025 CMA guidance or the eight live investigations
  • · Drip-pricing patterns left on the product page or in checkout (delivery, booking or service fees only shown at the final step) and no answer on how the team handles total-cost display under the new rules
  • · No post-iOS attribution stack on offer: pixel-only tracking, no CAPI, no server-side, and no view on how to read platform numbers against MER or contribution margin
  • · Weak CRO discipline (no test calendar, no win-rate evidence, no segmentation across mobile and desktop) and no working knowledge of the return-rate impact on net ROAS for the brand's category
Frequently asked

What brands ask about agencies for e-commerce.

5 questions our editors get most often, answered honestly. No agency-marketing speak.

Curated by humans

UK ecommerce retainers cluster in three bands. Boutique CRO and Shopify-build specialists run £3,000-8,000 a month for a focused brief such as conversion optimisation, lifecycle CRM or a single paid channel. Mid-market growth agencies sit at £8,000-15,000 a month for integrated programmes covering paid media, email, CRO and analytics. Full-stack Shopify Plus partners and performance shops working £2m-plus revenue brands land at £7,500-15,000 a month all-in once apps, retainer and observability tooling are stacked, and rise from there as media spend scales. Project work like a Shopify Plus migration, headless rebuild or DTC brand launch is usually scoped separately at £25,000-250,000. Media spend on Meta, Google, TikTok and the retail media networks sits outside the retainer and is almost always the largest line on the plan.
