A Google Ads agency for online stores, not for just any advertiser

Selling on Google is not the same as generating leads. In eCommerce, the account depends on the product feed, the margin of each SKU, stock and seasonality. That’s why we treat Google Ads as a sales channel connected to your catalog and your data: we structure campaigns by profitability, feed the algorithms with quality conversions and measure what really matters, the profit each order leaves. As a Google Premier Partner we get early access to betas, ongoing training and direct support from Google, and we put all of it to work for your online store.

The challenge

What usually holds an eCommerce back on Google Ads

  1. 01

    ROAS that doesn’t pay

    The account boasts a strong ROAS, but once you subtract costs, returns and shipping, the margin disappears. We optimize for profit, not gross revenue.

  2. 02

    Opaque Performance Max

    PMax spends wherever it wants and you don’t know which products or audiences work. We segment it by product groups and signals to regain control.

  3. 03

    Weak product feed

    Generic titles, empty attributes and products disapproved in Merchant Center limit your Shopping reach before you even start bidding.

  4. 04

    Incomplete measurement

    Without enhanced conversions or server-side tagging, the algorithms learn from partial data and make worse bidding decisions.

Fewer empty clicks, more orders that deliver profit.

What we do

What we do in your Google Ads account

We cover the entire Google Ads ecosystem applied to online sales.

01

Google Shopping

We design Shopping campaigns by category, margin and turnover. We prioritize the most profitable products and control the searches that trigger them.

02

Performance Max

We set up PMax with asset groups by product line, first-party audience signals and brand exclusions. We combine it with standard Shopping when a comparison makes sense.

03

Search and brand

We cover generic, category and brand searches with responsive ads and extensions. We protect your brand from competitors and resellers.

04

YouTube and Demand Gen

We activate video and discovery formats to generate new demand and feed remarketing. We measure their impact on brand searches and assisted sales.

05

Feed and Merchant Center

We optimize feed titles, attributes and custom labels, using tools like Channable when the catalog calls for it. We resolve disapprovals and policy warnings.

06

Measurement and first-party data

We implement enhanced conversions, Consent Mode and margin-based conversion values. We connect customer data so bidding learns from real buyers.

Frequently asked questions

What we’re often asked.

What are the benefits of working with a Google Premier Partner agency?

Premier Partner is the highest tier of Google’s partner program. It means up-to-date certifications, early access to betas and new features, ongoing training and a Google support team to resolve issues and review account opportunities. For your eCommerce, that means more applied expertise and less time wasted on trial and error.

Performance Max or Google Shopping for my online store?

It depends on your catalog, conversion history and how much control you need. PMax usually scales well with a good feed and strong signals, while standard Shopping gives more visibility into searches and products. Often the best answer is to combine them with clear rules so they don’t compete with each other.

How much should I invest in Google Ads for an eCommerce?

There’s no universal figure. We calculate the investment based on your margins, average order value, search volume in your sector and growth goals. We start with a budget that allows learning from enough data and scale it as campaigns prove profitable.

Can you work on my existing Google Ads account?

Yes. We always work in an account that you own and keep its history, which is very valuable for the bidding algorithms. After the audit we decide what to restructure and what to keep so no learning or performance is lost during the transition.

How do you measure campaign results?

Beyond clicks and CTR, we measure sales, ROAS, cost per acquisition, margin generated and the share of new versus returning customers. We cross-reference Google Ads data with your eCommerce platform and GA4 for a reliable view and data-driven investment decisions.
