Compare the top Google Shopping agency UK options for 2027, from feed optimisation and Performance Max specialists to Merchant Center and CSS partners.
For most UK retailers, Shopping ads and Performance Max now take the larger share of the Google Ads budget, and the results depend less on keyword choice and more on product data, bidding at product level and the commercial logic behind each campaign. Choosing a Google Shopping agency UK retailers can trust means looking at who actually handles that work: who rewrites the feed, who fixes Merchant Center disapprovals, who decides which products deserve budget and which should be held back.
The gap between strong and weak options is usually obvious once you ask the right questions. Good Shopping specialists talk about feed attributes, custom labels, margin and stock before they talk about ROAS. They can explain how they structure Performance Max so it does not swallow brand traffic or a handful of bestsellers. They also know whether a Comparison Shopping Service (CSS) arrangement makes sense for you, because in the UK and EEA a CSS can remove the margin Google keeps on Shopping clicks bought through Google’s own CSS. Weaker agencies treat Shopping as a box on a broader PPC retainer, leave the feed untouched and lean on automated bidding to fill the gaps.
This list favours UK businesses where Shopping, feeds and CSS are a core part of the work rather than an add-on. We checked each company on its own website for its location, its Shopping and feed services, and any clients, results, partner status or awards it publishes. Where a company makes a claim we could not confirm on its own site, we left it out. Retailers who want a broader full-funnel paid media partner should also look at our separate guide to ecommerce PPC agencies.

Best Google Shopping Agencies In The UK For 2027
1. Bidnamic — SKU-Level AI Bidding For Shopping And Performance Max
Bidnamic is a Leeds-registered company that describes itself as a mix of agency and software. It manages Google Ads and Microsoft Ads for ecommerce brands, with its own technology setting bids around purchase intent at the level of individual products rather than broad product groups. That makes it a natural fit for retailers with tens of thousands of SKUs, where manual bidding cannot keep up and a single Performance Max campaign tends to pour spend into a few bestsellers.
Its service covers Shopping and Performance Max strategy, search ads, Microsoft Ads and product feed optimisation, including title structure, data enrichment and A/B testing of feed changes. Bidnamic also runs its own CSS, offered free to eligible UK and EU retailers, so clients can buy Shopping clicks without the margin retained under Google’s own CSS. The company says it has spent around a decade refining its approach and publishes more than 70 case studies.
Named results on its site include a 62% ROAS uplift for LD Mountain Centre, a 48% higher conversion rate for New Forest Clothing and an 87% conversion rate increase for Allied Brass. Brands such as Huel, Herschel Supply and Rab also appear on the site. Bidnamic suits mid-sized and large retailers that want product-level control without building that capability in-house.
2. Productcaster — Premium CSS Partner With Feed And Testing Tools
Productcaster is based at The Fruit Market in Hull and operated by Summit Media 2.0 Limited, the same group behind the performance agency Summit. Its core product is a Comparison Shopping Service that runs across 21 European markets, including the UK, Germany, France, Spain and Italy. Productcaster states that it is a Premium Google CSS Partner, a status it describes as placing it in the top 5% of comparison shopping services in Europe, and it has won Google’s CSS Spotlight Awards, including the Business Growth award for three years running.
Around the CSS sits a set of tools: FeedManager for building and optimising product feeds across more than 60 channels, ProductMaximiser for spotting feed issues and opportunities across Shopping and Performance Max, and ProductTester for running SKU-level experiments on feed attributes. Packages are priced as a fixed monthly fee starting at £75, with no commission on spend, and higher tiers add client success support, quarterly reviews and dedicated strategy time.
Clients named on the site include Wickes, THG, Wayfair, IKEA, Ann Summers, Silentnight, Naked Wines, New Balance and Bensons. The company reports traffic gains of up to 55% and CPC reductions of up to 45% in some sectors. Productcaster is best for retailers who already have campaign management covered and want a well-supported CSS partner UK teams can rely on, with feed tools on top.
3. Shoptimised — Feed Optimisation Platform With A Managed Service
Shoptimised is a Newcastle upon Tyne company, based at Cobalt Business Park, that focuses on product data for Google Shopping. It combines a feed platform with a managed service called Feed Accelerator, in which UK-based feed specialists audit a retailer’s catalogue, connect data sources, resolve Merchant Center issues and then rework titles, attributes, categories, product types and custom labels for margin, season or stock. Pricing for the managed service is quoted monthly after an initial review rather than sold in fixed packages.
The platform itself covers feed rules, performance rules, auditing, suggested optimisations, feed creation and reporting. Shoptimised also operates as a Google CSS partner and states that it holds Premium Partner status for 2026, with the CSS switch handled during onboarding. It reports more than 1,500 brands on the platform and over £500m in incremental revenue.
Named users include Schuh, Charles Clinkard, Hawes & Curtis, Mattress Next Day, Get the Label, Clubhouse Golf and Team Cycles, alongside several agencies that use the platform for their own clients. Shoptimised is the right call when the feed is the main constraint, and it is well placed for product feed optimisation work that an in-house team or existing agency cannot cover.
4. JudeLuxe — Profit-First Shopping Management With Its Own CSS
JudeLuxe is a Birmingham agency founded in 2021 by Chris Avery and Gee Kullar, working from Izabella House on Regent Place. It runs Google Ads for ecommerce brands with a focus on margin, stock and customer value instead of reported ROAS alone. Its BOI framework gives each SKU one commercial job, such as scale, profit, protect, recovery or gateway, and campaigns are built around those roles. The agency won Best Small PPC Agency at the European Search Awards 2026.
Services cover Google Shopping, Performance Max, search, Microsoft Ads, feed engineering for Shopify, WooCommerce and Adobe Commerce, and a certified Google CSS. The CSS is free with no setup fee, contract or revenue share, and can be used without a managed engagement. Managed accounts are charged a fixed monthly fee from £2,000, with no percentage of spend.
The agency publishes results for Thermos, where contribution margin rose 94% and revenue 86% after double-counted conversions were corrected, and for UK Soccer Shop, where it reports £520k in gross cash recovered from aged stock. Other named clients include Triumph, Refy, Loaf, Lisa Angel and Ed Hardy. JudeLuxe suits brands that want Shopping run as a profit and inventory lever, not just a revenue channel.
5. Found — Premier Partner Shopping Support For Larger Retailers
Found is a London agency based on Hatton Garden, with a second office in New York, and part of Tomorrow Group alongside the data consultancy Braidr. It is a Google Premier Partner and also holds Microsoft and Meta partner status, ISO 27001 certification and The Drum Recommended Agency listing. In 2026 it won Standout PPC Agency of the Year at the UK Digital Excellence Awards.
Its Google Shopping service covers Performance Max management across the full catalogue, feed optimisation in Merchant Center working alongside a client’s feed management partner, custom reporting and product creative for Shopping ads. Because it also offers SEO, digital PR, data science and CRO, larger retailers can keep Shopping inside a wider programme without juggling several suppliers.
Found lists Toolstation, Secret Sales, Peacocks, Bonmarché, And So To Bed, Faux Flower Company and Atkin & Thyme among its clients. Its Toolstation case study reports a 40% year-on-year uplift with a 10% stronger target ROAS, and the founder of Secret Sales credits the team with allowing a several-fold increase in media budgets. Found is a sound choice for established retailers that want Premier Partner access and a team used to large product ranges.
Visionary Marketing is a UK agency with offices in London and Middlesbrough, led by founder Chris Coussons, who brings more than 15 years in performance marketing. It is a Google Partner and Microsoft Ads Partner and runs Google Shopping management UK retailers can buy on month-to-month terms, with fees between £800 and £3,000 per month on top of ad spend.
Its Shopping service covers campaign setup and daily bid optimisation, feed work on titles, categories, supplemental feeds and margin-based custom labels, Merchant Center monitoring and disapproval fixes, and Performance Max with asset groups split by category and margin. It favours hybrid structures that run Standard Shopping alongside PMax, and it can activate a CSS partner for eligible accounts. It works across Shopify, WooCommerce, Magento, BigCommerce and custom builds.
Published results include 9.31x ROAS in the first month for Strictly Beds and Bunks, a 1,066% revenue increase over seven months for US fabrics brand LA Design Concepts, and a 50% profit increase in three months for Oh My Cream. The agency is open that typical clients land at 3x to 5x ROAS. It suits SMEs that want a senior specialist on the account rather than a junior team.
7. Cedarwood Digital — Award-Winning Retail PPC With SEO Under One Roof
Cedarwood Digital is a Manchester agency based at Linley House on Dickinson Street, offering paid media, SEO and digital PR. It is a Google Partner and Microsoft Partner and has a strong recent awards record, including Best PPC Campaign (Retail/Ecomm) and Best Small Integrated Agency at the European Search Awards, and Best PPC Agency at the UK Search Awards 2025.
Its Google Shopping service treats feed management as the foundation, with feeds connected by XML or through platforms such as Shopify, product data managed in Merchant Center, product-level bidding with device, time and country conditions, and Performance Max used across the account. The team also advises on CSS options for retailers selling in the EEA and on seller ratings.
Cedarwood publishes Shopping-specific results: 100% growth over two years and 1,050% ROAS for Hayes Garden World, 60% year-on-year growth for Casa Bella Furniture, a 27% sales increase across 33 countries for Watches2U and a 74% revenue increase for Salt Of The Earth. It is a good match for retailers who want Shopping and organic search planned together by one team.
8. The SEO Works — Premier Partner With Partner CSS Bidding
The SEO Works is an employee-owned agency established in 2009, based in Sheffield with teams in London and Leeds. It is a Google Premier Partner and has collected a long list of industry awards, including SEO Agency of the Year and Integrated Search Agency of the Year. Brands shown on its site include Zippo, Denby, Roland, Rab and Peter Werth London.
Its Google Shopping management service covers feed enhancement, adding brand, material and size detail to product titles and mapping products to accurate categories, with changes applied on top of the existing feed so the website’s own data stays untouched. The team monitors Merchant Center for errors, warnings and missing data and handles disapprovals, and it typically runs Performance Max alongside Standard Shopping. Through a partner CSS, it buys Shopping clicks without Google’s CSS margin, which it says gives roughly 25% more bidding power for the same spend.
The SEO Works suits retailers that want the reassurance of Premier Partner status, solid Google Merchant Center support and the option to combine Shopping with SEO from the same agency.
9. Doublespark — Custom Label Structures And Feed Health Monitoring
Doublespark is a Cambridgeshire agency founded in 2005, with offices in Cambridge, Peterborough and March. It is a Google Partner and offers PPC, SEO and ecommerce web design, with Google Shopping ads as a dedicated service. The team works with Merchant Center, Google Ads Editor, GA4, DataFeedWatch or Channable, Looker Studio and custom scripts.
Its Shopping work starts with the feed: resolving disapprovals and improving titles, descriptions, GTINs, images and categories, then handling Merchant Center connections, shipping and returns settings and promotions. Campaigns are grouped using custom labels for bestsellers, high-margin lines and seasonal stock, and Performance Max is run with audience signals and asset management rather than left unchecked. Dynamic remarketing, price competitiveness monitoring and international Shopping expansion are also offered.
Doublespark’s Shopping case studies are anonymised, but report a 136% ROAS increase in eight weeks with 46% lower cost per sale for a UK-wide ecommerce brand, and a 43% ROAS increase with 110% order growth for an outdoor and garden retailer. It suits regional and growing online stores that want an experienced, approachable team.
10. Opace — Merchant Centre Setup And Catalogue-Scale Feed Rules
Opace is a UK digital agency, part of Jakey Group, with offices at Brindley Place in Birmingham and in Letchworth Garden City. It has more than 15 years in business, holds Google Partner status and carries a 5.0 Clutch rating. Its Google Shopping service is aimed at retailers with large or technical catalogues.
The team handles Merchant Centre account creation, verification, feed connection, policy compliance and disapproval fixes, escalating to Google support when needed. Feed work covers titles, descriptions, categories, images, pricing, availability and custom labels, using automated rules for large catalogues with manual review for edge cases. Campaigns combine Standard Shopping, Performance Max for retail and smart bidding, segmented by category, margin, seasonality and performance, with daily bid management.
Opace’s ecommerce clients include Corcorans Home & Furniture, Shedstore, DTC, Cranes Direct, Ironmongery Online and Lifting Gear Direct. It is a practical choice for trade, industrial and home retailers that need their Merchant Centre account put in order before scaling spend.
How To Choose A Google Shopping Agency In The UK
How much of the work is feed work?
Ask the agency to show you what it would change in your feed in the first month. A specialist should be able to talk about title structure, product types, GTINs, custom labels and supplemental feeds in specific terms, and should know which tools it uses to apply changes. If the answer is mostly about bid strategies and campaign settings, the feed is probably being left as it is, and product feed optimisation is often where the quickest gains sit.
Should you use a CSS partner?
If you advertise Shopping in the UK, EU or Switzerland and still buy through Google’s own CSS, you are paying a margin that a third-party CSS can remove. Most CSS partner UK options are free or low-cost and take little time to switch. Check whether the agency runs its own CSS, works with a partner, or will let you keep an existing one, and confirm that the switch applies to each Merchant Center sub-account.
How will Performance Max be structured?
Performance Max for retail can work well, but left alone it tends to favour bestsellers, branded traffic and remarketing. Ask how the agency splits asset groups, whether it runs Standard Shopping alongside PMax, how it uses custom labels for margin or stock, and what reporting it gives you on where the spend actually goes.
Does the agency report on profit or just ROAS?
ROAS can look healthy while margin falls, especially when discounted or low-margin lines take the budget. Good agencies will ask for margin data, stock levels and returns rates, and will report on contribution or profit where you can provide the inputs. If an agency never asks about your margins, treat its ROAS targets with care.
Who will handle Google Merchant Center support?
Disapprovals, account warnings and suspensions can stop Shopping traffic overnight. Find out who monitors Merchant Center day to day, how quickly they respond to issues, and whether they have experience resolving policy problems and misrepresentation flags. This is often the difference between a brief dip and weeks of lost sales.
What does the pricing model reward?
A percentage-of-spend fee rewards higher spend, while a fixed fee rewards efficiency. Neither is wrong, but you should know which one you are signing up to and what happens to fees as budgets grow. Also check notice periods: several agencies on this list work month to month, which keeps the pressure on results.
Conclusion
The right Google Shopping agency UK retailers choose will depend on where the weak point sits. If product data is the problem, a feed specialist such as Shoptimised or Productcaster will usually move the needle faster than a new account manager. If you need product-level bidding across a large range, Bidnamic is built for it, while JudeLuxe and Visionary Marketing suit brands that want margin and stock to drive the campaign logic. Found, Cedarwood Digital and The SEO Works make sense when Shopping needs to sit inside a broader search programme.
Whichever route you take, ask for a feed audit, a clear Performance Max plan and an answer on CSS before you sign.
