E-commerce PPC Agency Measured On Margin
For many online retailers, paid search is one of the largest lines in the marketing budget, and much of it runs through Google Shopping and Performance Max. We run e-commerce PPC around the numbers your finance team checks: revenue, return on ad spend and margin, with product feeds, bidding and budgets set up to put spend behind the products worth selling.

Revenue is the easy part. Profitable revenue is the job.
Plenty of e-commerce accounts look healthy on ROAS and still lose money on part of what they sell. Spend spreads evenly across the catalogue, Performance Max takes credit for branded searches you would have won anyway, and low-margin bestsellers absorb budget that should go to the lines that pay.
We fix that with a cleaner product feed, campaigns segmented by margin and stock, and bidding fed with the order value and profit data your business already holds. The result is a Shopping and Search programme you can scale, because you can see what each product line returns.
Senior Specialists. Feed-First Thinking. Every Pound Accounted For.
Built Around Search. Measured on Revenue

Spend Behind The Products Worth Selling
Google decides where your products appear largely from your product data, so the feed comes first. We clean titles, attributes and categories, add custom labels that separate high-margin lines from clearance stock, and use them to set budgets and targets. That way bidding works from what each product earns, not from an even split across the catalogue.
- Bidding built around margin, not just ROAS
- Product feeds that match how shoppers search
- Performance Max kept off your branded traffic
- Budget moved to the products that pay back
- Shopping, PMax and Search working without overlap
- Reporting in revenue, ROAS and gross profit

Google Shopping Management Measured On Margin
E-commerce Paid Search That Paid Back
What E-commerce PPC Delivers For The Business
The aim is paid search revenue you can scale without margin leaking away, with a clear view of what each product line and campaign returns.
Profitable Revenue Growth
Spend concentrated on the products that make money, so revenue grows without the margin disappearing into advertising costs.
Lower Cost Per Sale
Clicks on irrelevant searches and branded traffic you would have won anyway cut back, so each order costs less to win.
A Feed That Works Harder
Product data that matches how shoppers search, so your products appear for more relevant queries and fewer wasted ones.
Control Over Performance Max
Automation pointed at the right goal, with exclusions, negative keywords and reporting that show where the budget actually goes.
More New Customers
Bidding that can value first orders more highly, where acquiring new customers matters more than selling again to existing ones.
Reporting Finance Will Trust
Revenue, ROAS and gross profit by category and campaign, in a real-time dashboard and a monthly review with your account lead.
