Retail & E-Commerce Marketing in London
Growth for product brands, online stores and bricks-and-mortar retail, run by a Mayfair agency that treats your storefront and your shopfront as one system.
Retail buyers do not separate online and offline the way agencies often do. Someone discovers your brand on Instagram, checks your Google listing, reads a review, then either buys on your Shopify store or walks into your shop. Byter Digital builds marketing that respects that whole journey, so your paid social, search, email and in-store activity push in the same direction rather than competing for credit. We have worked with London product brands, food and drink retailers and DTC stores since 2018.
The fundamentals of profitable retail marketing are unglamorous: a fast, well-structured store, a clean product feed, audiences that are actually worth bidding on, and an email and SMS programme that turns first orders into repeat ones. We get those right before we scale spend, because pouring budget into Performance Max or Advantage+ shopping over a leaky site is how brands lose money quietly. Our job is to find where margin is leaking and close it, then grow what is already working.
Whether you sell exclusively online, run a physical shop, or both, we tailor the mix. A Shopify-only DTC brand needs different priorities to a Soho parlour driving local footfall, and we plan accordingly. Everything is measured against revenue and contribution, not vanity metrics, and you keep full ownership of every ad account, pixel, store and list we touch.
How we work in Retail & E-Commerce
The specific work we do for clients in this category. Each piece is sized to the brief and the budget.
E-Commerce SEO & Product Pages
We structure category and product pages so they rank for the searches that convert, not just high-volume head terms. That means clean URL and collection architecture, optimised product titles and descriptions, schema markup for products and reviews, and technical fixes that stop duplicate variant pages diluting your rankings. For shops with a physical presence, we also build the local SEO and Google Business Profile work that captures nearby buyers.
Shopping Ads & Product Feeds
A profitable shopping campaign starts with a clean feed. We optimise your Google Merchant Centre and Meta catalogue feeds, fix disapprovals, enrich titles and attributes, then run Performance Max and Advantage+ shopping with proper structure and exclusions rather than letting the algorithm spend blind. We segment by margin and best-sellers so budget follows the products that actually make you money.
Paid Social for DTC
For direct-to-consumer brands we build Meta and TikTok campaigns around creative that earns the click: short-form video, founder content, user-generated reviews and clear offers. We test creative systematically, set up proper conversion tracking with the Conversions API, and scale the angles that hold their cost per acquisition rather than chasing reach. Creative volume is the lever in paid social, so we treat it as a production line.
Email & SMS with Klaviyo
Most retail brands leave the easiest money on the table in their email programme. We build Klaviyo flows that do the work automatically: welcome series, browse and cart abandonment, post-purchase, winback and replenishment. On top of that we run a planned campaign calendar tied to launches, seasons and stock, plus list growth and segmentation so the right offer reaches the right buyer.
Conversion Rate & Site Speed
Sending traffic to a slow or confusing store wastes every other pound you spend. We audit Core Web Vitals, compress and lazy-load imagery, tidy app bloat on Shopify, and fix the checkout and product-page friction that quietly kills conversion. Then we test the high-impact changes, from product imagery and reviews to delivery messaging and trust signals, so more of your existing visitors buy.
Content & Social Management
Retail lives on a steady stream of product imagery, video and social proof. We plan and produce content that suits each platform and shoot it where needed, then manage your organic social so the feed supports both online sales and local discovery. Strong owned content also feeds your ads, your email and your product pages, so one shoot works several times over.
How an engagement runs
The shape of a typical project from first conversation through to ongoing operation.
Audit
We start by pulling apart what you have: store performance and speed, product feed health, ad account structure, email flows, analytics setup and current revenue by channel. For retailers with a shop, we also look at how online demand and local footfall interact. The output is a clear picture of where margin is leaking and where the fastest wins sit.
Target-setting
We agree the numbers that matter, typically revenue, contribution after ad spend, return on ad spend and repeat purchase rate, alongside realistic targets for the first few months. We map which products and audiences carry the growth and decide where to invest first, so effort is not spread thinly across everything at once.
Build
We fix the foundations before scaling: feed and tracking, store speed and conversion issues, and the core Klaviyo flows. Then we stand up the campaigns, whether that is Performance Max, Advantage+ shopping, paid social or local search, with proper structure, creative and measurement in place from day one.
Iterate
Retail is seasonal and fast-moving, so we review performance against targets on a regular rhythm, cut what is not working and double down on what is. We keep feeding fresh creative into paid social, expand winning campaigns, sharpen email segmentation and revisit CRO as new data comes in. Reporting is plain and tied to revenue.
Selected work in this category
A handful of clients from the retail & e-commerce marketing category. The full portfolio sits at /our-work/.
Collision Drumsticks
A product and retail brand from the music world where we run social media and advertising to build awareness and drive sales of the drumstick range. The work pairs strong product and player content with targeted paid campaigns.
Sohocreamery
A Soho ice cream parlour where we produce the kind of visual content that travels, driving both social following and real footfall through the door. Strong imagery and video turn a small site into a recognisable local destination.
Beans & Bubbles
A new cafe and product brand launch where we built the brand identity and ran social to drive opening footfall. The work gave the brand a clear look and a ready audience from day one.
Why work with Byter on this
The honest version of what makes Byter the right partner for this category.
We connect online and footfall
Most agencies treat e-commerce and physical retail as separate problems. Our largest experience is hospitality and London product brands, so we plan paid social, search and content to drive online orders and walk-in trade together, measuring how each supports the other rather than claiming the same sale twice.
Feeds and tracking done properly
Profitable shopping campaigns and clean Conversions API tracking are unglamorous work that many agencies skip. We get Merchant Centre, Meta catalogues and pixels right first, because Performance Max and Advantage+ only perform when the data feeding them is clean.
Margin before reach
We optimise to contribution after ad spend and repeat purchase, not vanity reach. We fix site speed, CRO and email flows so your existing traffic converts harder before we scale budget, which protects margin as you grow.
You own everything
Every store, ad account, pixel, product feed and Klaviyo list stays in your name. We build assets that remain yours, so you are never locked in and never lose your data if you move on.

Frequently asked questions
Do you work with both online stores and physical shops?
Yes. We work with pure DTC and e-commerce brands, with bricks-and-mortar retailers, and with brands that do both. For online stores we focus on store performance, feeds, paid media and email. For shops we add local SEO and footfall-driving social, and where a business runs both we plan the two together so they reinforce each other.
Which platforms do you support, Shopify or WooCommerce?
Both. Most of our retail work runs on Shopify or WooCommerce, and we are comfortable optimising, fixing speed issues and building on either. We can advise on the right platform for your stage if you are launching or considering a move, and our blog includes a platform comparison to help you weigh it up.
How do you run shopping ads profitably?
It starts with a clean product feed in Google Merchant Centre and your Meta catalogue. We enrich titles and attributes, clear disapprovals, then run Performance Max and Advantage+ shopping with sensible structure, exclusions and margin-based segmentation rather than letting the algorithm spend without guardrails. We measure against contribution after ad spend, not just return on ad spend in isolation.
Can you set up our email and SMS marketing?
Yes, we build and manage email and SMS programmes, usually in Klaviyo. That covers the core automated flows, welcome, abandoned browse and cart, post-purchase, winback and replenishment, plus a planned campaign calendar tied to launches and seasons, and the list growth and segmentation behind it. For many retail brands this is the fastest route to extra revenue.
What does it cost to work with you?
Our retainers come in three tiers: Bronze at GBP 750 per month, Silver at GBP 1,500 per month and Gold at GBP 3,000 per month, scaling with the number of channels and the depth of work involved. Content shoots are charged separately at GBP 650 plus VAT for a half day and GBP 1,200 plus VAT for a full day. We will recommend the tier that matches your goals and current stage.
How quickly will we see results?
Paid social and shopping ads can start producing sales within the first few weeks once tracking and feeds are clean, while email flows often add revenue almost immediately. SEO and organic growth build over a few months. We set realistic targets up front and report against revenue so you can see what each channel is contributing.
Do we keep ownership of our accounts and data?
Always. Your store, ad accounts, pixels, product feeds, analytics and Klaviyo lists stay in your name throughout. We build everything inside assets you own, so there is no lock-in and nothing leaves with us if you decide to part ways.
