Ecommerce marketing that grows profit, not vanity ROAS
Selling online has never been pricier. Ad costs keep climbing, attribution keeps fibbing, and every rival is one discount code away. 21 Degrees Digital is the ecommerce marketing agency that runs brand and performance as one data-led system, measured in revenue and margin. We don't make a move the data doesn't back.
Selling online is brutal in ways other sectors don't see. Here's what you're really up against.
01
Acquisition costs won't stop climbing. Ecommerce customer acquisition costs are up roughly 40% in two years. Google Shopping clicks got about a third pricier in 2025 while average returns fell. You're paying more to win less.
02
Your ROAS is flattering you. Blend in branded search and repeat buyers and any dashboard looks heroic. Strip them out and the picture changes. Dashboards flatter. P&Ls don't.
03
Attribution broke and never came back. Once Apple let people opt out of tracking, most did. Now last-click takes credit for work your brand did, and the ad platforms mark their own homework.
04
The giants are inflating your auctions. Temu and Shein poured billions into ads and drove up prices for everyone. Marketplaces hand you traffic but take your margin, your data and your customer relationship.
05
Shopping has left the search box. Your buyers discover products on TikTok, Reddit, YouTube and in AI answers. Show up only in Google and you miss where minds get made up.
06
The discount treadmill. When shoppers can't tell you apart, price becomes the only lever. One-time bargain hunters wreck your unit economics, and without loyalty you're stuck running to stand still.
21 Degrees isn't a ROAS dashboard with a logo. We're the ecommerce growth agency that builds brands the numbers can defend.
Most agencies split brand and performance into separate teams, separate budgets and separate reports. We don't. 21 Degrees runs them as one system, briefed from data on where your buyer actually shops, and measured so you can invest with confidence. It's data-led creativity: brave work, never a guess. And it compounds. We built a TikTok community for a DTC cleaning brand, and that brand equity turned into an 8.01× return on the ads and a national B&Q listing. Brand isn't the fluffy bit. It's the multiplier.

Ecommerce marketing is everything a brand does to attract shoppers, convert them into customers and keep them coming back. It spans paid media, SEO, social, email, content and brand building, plus the analytics that tie it together. Done well, it's one joined-up system that grows revenue and profit, not a set of disconnected channels chasing their own metrics.
Why work with an ecommerce marketing agency?
Because the game changed. Acquisition costs keep rising, tracking is patchier than it used to be, and buyers now discover products across search, social, marketplaces and AI assistants. A good ecommerce marketing agency brings the specialists, the data and the cross-channel view to grow profitably through all of it, without you hiring a full in-house team.
What makes 21 Degrees different from other ecommerce agencies?
We run brand and performance as one system instead of two departments, and we measure in revenue and margin rather than vanity ROAS. Our briefs start with data on where your buyer actually shops, including the AI answers and social platforms most agencies ignore. And we slot in alongside your team rather than replacing it.
Do you work with Shopify, WooCommerce and Amazon?
Yes. We work across the platforms that matter to UK ecommerce, including Shopify, WooCommerce and Amazon, plus the ad platforms that feed them. Whether you sell direct, through marketplaces or both, we build the strategy around your margin, not the platform's.
How do you measure success?
Honestly. We won't claim credit for every sale your whole team helped win, because that's how agencies lose trust. Instead we report the numbers that matter, revenue, margin, customer value and where your brand is showing up, in plain English, so you can invest with confidence.
How much does ecommerce marketing cost?
We sell days, not channels. Plans start at £1,600 a month for two days of focused work and scale to our full Outcome Marketing offer at £6,400 a month. You pick the firepower that fits where you are now and scale when the results say so.
Do you work with DTC brands, and what size of business suits you best?
We work with DTC brands, multi-channel retailers and marketplace sellers. Our sweet spot is established UK businesses ready to invest in growth, typically £3M+ turnover, but the honest answer is fit matters more than size. If you want profitable growth and you're open to brave, data-backed work, let's talk.
