Ecommerce PPC
What does an ecommerce PPC agency do differently?
An ecommerce PPC agency manages your product feed as carefully as your ads, and sets targets by profit per product rather than revenue.
ProntX is an ecommerce PPC agency for UK online shops on Shopify, WooCommerce, Magento and BigCommerce. We run Google Shopping, Performance Max and Microsoft Shopping from a clean Merchant Center feed, with ROAS targets set by your real margins. Management starts from £450 a month.
Retail PPC is mostly won or lost before an ad is shown. Google decides which of your products to show, for which searches, largely from your product feed: titles, descriptions, categories, prices, images and identifiers. A weak feed means your products appear for the wrong searches, or not at all, whatever your bids are.
The second problem is targets. A single account-wide ROAS target treats a 15 percent margin accessory the same as a 60 percent margin own-brand product. Google will happily chase revenue from the low-margin items, and the account looks healthy while profit leaks away.
Our ecommerce PPC management deals with both. We take ownership of the feed, structure campaigns around margin bands and product performance, and report on profit after ad spend, not just revenue.
We also look beyond Google. Microsoft Shopping often brings cheaper clicks from an audience that buys, and Meta catalogue ads can bring back shoppers who viewed a product and left.
Product feeds
How we optimise your Merchant Center feed
We treat the feed as the foundation of every Shopping and Performance Max campaign. Better titles and attributes mean better matching, which means cheaper, more relevant clicks.
Matching
Titles and attributes
Product titles rewritten to front-load what people search for (brand, product type, key attribute, size or colour), with complete GTINs, MPNs, Google product categories, product types, material, gender and age group where relevant.
Control
Custom labels
Every product tagged with custom labels for margin band, price range, best seller status, seasonality and stock depth. These labels drive campaign structure and let us move budget without touching individual products.
Health
Disapprovals and warnings
Weekly checks for disapproved products, price and availability mismatches, missing shipping or returns settings, and image policy issues. Lost products are lost sales, so we fix these first.
Extras
Promotions and free listings
Merchant promotions for sales and discount codes, product ratings where you qualify, local inventory if you have a shop, and free listings across Google surfaces so your products appear beyond paid placements.
Where your platform’s default feed app cannot produce what we need, we use a feed management tool or supplemental feeds in Merchant Center, so you do not have to change how your shop is built.
Profit first
How do you set ROAS targets by margin?
We work out the return on ad spend each product group needs to break even, then set targets above that line. Revenue that loses money is not growth.
Break-even ROAS is one divided by your gross margin. A product with a 40 percent margin breaks even at a ROAS of 250 percent: for every pound spent on ads, it needs to bring in two pounds fifty of revenue just to cover product cost and ad cost. A product with a 20 percent margin needs 500 percent. One target cannot serve both.
So we group products into margin bands using custom labels, and give each band its own campaign or asset group with its own target ROAS.
- High-margin and own-brand products: lower ROAS targets, more budget, room to win new customers
- Mid-margin core range: balanced targets tuned weekly on actual profit
- Low-margin or price-led items: tight targets or excluded entirely if they only lose money
- Zombie products with no impressions: isolated so they get a fair test
- New customer value set where repeat purchase rates justify paying more for a first order
Campaigns
Which ecommerce PPC campaigns do we run?
Most online shops need a mix of Performance Max, standard Shopping, brand search and remarketing, structured so you can see what each one contributes.
Performance Max
Split by margin band or category, with brand exclusions so it cannot inflate results by taking credit for people already searching for your name. Feed-only asset groups where creative is thin.
Standard Shopping
Used alongside PMax for control: testing new products, protecting hero lines, or running query-level negatives that PMax does not allow at the same depth.
Microsoft
Microsoft Shopping
Imported from Google Merchant Center, then managed separately with its own bids and negatives. Often cheaper clicks and a useful extra slice of sales for very little setup.
Search
Brand and category search
Brand terms protected at a low cost, and high-intent category searches covered with text ads that point to the right collection page.
Retention
Remarketing
Dynamic remarketing on Google and Meta catalogue ads for product viewers and cart abandoners, coordinated with your email marketing flows so customers are not chased twice.
Peaks
Seasonal planning
Black Friday, Christmas and sale periods planned weeks ahead: budgets raised, seasonality adjustments applied, promotions loaded and stock levels checked.
Why ProntX
Why choose ProntX for ecommerce PPC management?
Because the same team can fix your feed, your tracking and your shop. Most ecommerce PPC problems trace back to one of those three.
Tracking you can trust
We check purchase tracking against your shop’s order data, set up enhanced conversions, and make sure revenue is passed correctly to GA4, Google Ads and Microsoft. Duplicate purchase events and missing tax or shipping handling are surprisingly common, and they make every ROAS figure wrong.
Product pages that convert
Our ecommerce web design team can fix slow product pages, unclear delivery information and clunky checkouts, which raises conversion rate on every paid click without increasing spend.
Paid and organic together
Shopping data shows which products and searches convert. We share that with our ecommerce SEO team so category pages are written for the terms that actually sell.
Honest terms
Rolling monthly, fixed fees, no markup on ad spend. Your Merchant Center, Google Ads and analytics accounts stay in your name.
Who it is for
Which online shops are a good fit for ecommerce PPC?
Ecommerce PPC works best for shops with healthy margins, reliable stock and a product people already search for by name or type.
We work with independent brands and established retailers selling to UK customers, and to Europe and North America where shipping makes sense. Fashion, beauty and skincare, home and garden, automotive parts, health supplements, gifts and specialist equipment are all categories where Shopping does a lot of the work, because buyers compare products visually and on price.
If your products are new or unusual and nobody searches for them yet, search-based PPC has less to work with. In that case, demand usually has to be created first, and our paid social team can run Meta and TikTok prospecting that feeds people into your Shopping and remarketing campaigns.
- Average order value high enough to absorb a realistic cost per sale
- Gross margins you are willing to share, even as bands
- Stock levels that can handle extra demand at peak times
- Delivery and returns information that is clear on every product page
- Someone on your side who can approve offers and new products quickly
What happens in the first 60 days
In the first fortnight we audit the feed, check purchase tracking against your order data and agree margin bands with you. By week four the feed fixes, custom labels and new campaign structure are live. Weeks five to eight are about tuning: adjusting ROAS targets per band, adding Microsoft Shopping, testing standard Shopping against PMax for key categories and setting up remarketing. At day 60 you get a review showing revenue, ad spend and estimated profit by product group, so decisions about budget are made on margin rather than headline ROAS.

Talk to us
What is a good ROAS for an online shop?
There is no universal number. A good ROAS is one above your break-even point, which is one divided by your gross margin. A 50 percent margin breaks even at 200 percent ROAS, a 25 percent margin at 400 percent. We calculate this for each product group and set targets above it, so every target reflects profit.
Should I use Performance Max or standard Shopping?
Usually both. Performance Max is strong at finding buyers across Google, but gives less visibility and control. Standard Shopping is useful for testing new products, protecting hero lines and tighter negatives. We split them by margin band or category and add brand exclusions so PMax cannot claim credit for existing brand searches.
Do you manage the Merchant Center feed?
Yes. Feed management is included in every ecommerce plan. We optimise titles, attributes, categories and custom labels, fix disapprovals and warnings, set up promotions and free listings, and monitor feed health weekly. Where your shop's feed app is limited, we use supplemental feeds or a feed tool.
Is Microsoft Shopping worth it for UK shops?
For many shops, yes. Setup is light because campaigns import from Google Merchant Center, clicks are often cheaper, and the audience tends to be older with higher spending power. We manage it separately with its own bids and negatives rather than leaving an import running unchecked.
Which ecommerce platforms do you work with?
We work with Shopify, WooCommerce, Magento, BigCommerce and most platforms that can produce a product feed. We check purchase tracking against your platform's order data before trusting any ROAS figure, because duplicate or missing purchase events are common after theme or checkout changes.
How do you handle Black Friday and Christmas?
We plan peaks weeks in advance. That covers budget forecasts, seasonality adjustments so smart bidding expects higher conversion rates, Merchant Center promotions, stock checks for hero products and a post-peak plan so campaigns do not overspend once demand drops in January.
What does ecommerce PPC management cost?
Our ecommerce PPC management starts from £450 a month plus VAT for shops spending up to £3,000 on ads. Growing brands typically pay £750 to £1,250, and large catalogues more, depending on SKUs and markets. Ad spend is separate and paid directly to Google and Microsoft. See our pricing page.
Can you also run Meta catalogue ads?
Yes. Dynamic product ads on Facebook and Instagram are a natural partner to Shopping, especially for remarketing product viewers and cart abandoners. They use the same catalogue and are coordinated with your Google campaigns and email flows. Larger Meta prospecting work sits within our paid social service.
