What We Do
What Does an Ecommerce PPC Agency Do?
An ecommerce PPC agency runs the paid ads that put your products in front of people searching to buy them, then manages spend so each product earns more than it costs. For Google Ads, that means these six jobs.
Google Shopping Ads
Product listings that appear at the top of search results with images, prices, and reviews.
Performance Max
One campaign that serves your products across Search, Shopping, YouTube, Display, Gmail and Maps, steered by your feed and conversion data.
Search Campaigns
Text ads on the product and brand searches of people who are ready to buy.
Remarketing & Display
Re-engage visitors who browsed but didn't buy. Bring them back to complete the purchase.
Merchant Center Management
Feed optimization, product data quality, and compliance to keep products approved and Shopping ads serving.
Conversion Tracking
Purchase tracking with order value, enhanced conversions and server-side tagging, so every sale is attributed. See our conversion tracking setup.

Campaign types
Which Google Ads Campaigns Work Best for Online Stores?
Most online stores need Shopping or Performance Max for product searches, plus a Search campaign for brand and high-intent terms. The right mix depends on how much control you need over each product.
| Campaign | Where ads show | What drives it | Best for |
|---|---|---|---|
| Standard Shopping | Shopping results and the Shopping tab | Your product feed; no keywords | Control over bids per product group and clean search term data |
| Performance Max | Search, Shopping, YouTube, Display, Gmail and Maps | Feed, conversion data and your assets | Scaling proven products when tracking is accurate |
| Search | Text ads on Google Search | Keywords and ad copy | Brand terms, category searches and high-ticket products |
| Remarketing | Display and YouTube | Your site visitor lists | Bringing back visitors who left without buying |

What we fix
Why Do Ecommerce Google Ads Accounts Stall?
Ecommerce Google Ads accounts usually stall for structural reasons, not because of a single bad ad. These are problems we found in client accounts and how we fixed them.
One catch-all Shopping campaign
At Oil-Stores, over three-quarters of the budget sat in one Shopping campaign returning about 3x ROAS, with no room to push the products that paid.
Structure by product and margin
We split the catalog by category and margin, gave best sellers their own budget, and separated brand searches into their own campaign.
Spend rises, ROAS falls
Muir Way's revenue was stuck near $50K a month, and every budget increase pushed ROAS below break-even.
Scale only where ROAS holds
We separated prospecting from retargeting and raised budget only where incremental ROAS held, using a weekly scale-or-cut rule per campaign.
Feed written for the website
Product titles and attributes that read well on a product page often miss the words people type into Google.
Titles built for search
For Fire Pit Surplus we built titles around fuel type, size and material, and pushed high-margin products first.
Bidding on bad data
When conversion actions count page views or duplicate purchases, Smart Bidding chases the wrong signal.
Purchase value tracked once
We track purchases with order value as the primary conversion, add enhanced conversions and remove duplicates before scaling.
Process
How Do We Manage Google Ads for Ecommerce?
We manage ecommerce Google Ads in four stages, and each one has to be right before the next starts.
Audit
We review the Google Ads account, the Merchant Center feed and your tracking, then tell you what we found.
FreeFix Tracking and Feed
Purchases with order value, enhanced conversions, and feed titles and attributes cleaned in Merchant Center.
FirstRestructure
Campaigns split by category and margin, brand separated from non-brand, low performers capped instead of deleted.
ThenScale on Data
Budgets move each week toward the products and campaigns that hit your ROAS target, with a review call to walk you through it.
Every week
What is ecommerce PPC?
Ecommerce PPC is paid advertising for online stores where you pay for each click on an ad, most often on Google Shopping, Performance Max and Search. Your products appear with image and price when someone searches for them. Done well, it is measured by return on ad spend per product, not by clicks or traffic.
What e-commerce platforms do you work with?
We work with all major platforms: Shopify, WooCommerce, Magento, BigCommerce, Wix, and custom builds. The platform changes how we install tracking and connect the product feed to Merchant Center, not how we run the campaigns. Logical Gecko is also a Shopify Partner.
How fast will I see results?
We do not promise a date, because results depend on your margins, feed quality, budget and competition. What we control is the order of work: audit, tracking and feed fixes, restructure, then weekly scaling. For reference, Muir Way reached $488K in tracked revenue within its first 60 days with us.
What's the minimum ad spend you recommend?
For e-commerce, we recommend at least $3,000 to $5,000 a month in ad spend. Shopping and Performance Max campaigns need enough conversions to learn which products and searches pay, and smaller budgets spread thin across a large catalog. Our Google Ads cost guide shows how to set a budget from your own margins.
Do you handle Google Merchant Center?
Yes. Feed optimization, product data quality and policy compliance are part of how we manage Shopping and Performance Max, because a disapproved product cannot serve. We watch Merchant Center diagnostics, fix feed errors, and rewrite titles and attributes so products match the searches that convert.
Do you lock me into a contract?
No. Our ecommerce Google Ads management runs month to month, with 30 days written notice to end it under our terms of service. You keep admin access to your Google Ads and Merchant Center accounts throughout, and every campaign and all of the data stay with you if you leave.
Can you help if my Merchant Center is suspended?
Yes. Merchant Center suspension recovery is one of our core services: we find what triggered the suspension, fix the store and the feed, and prepare the review request. Google makes every reinstatement decision. Our Merchant Center case studies show 73,529 products approved across five recoveries, and our Merchant Center service explains the process.
Should I use Shopping or Performance Max?
Use Standard Shopping when you need control over bids per product group and clear search term data, and Performance Max when tracking is accurate and you want to scale proven products across every Google channel. Many stores run both, with Search for brand terms. We decide per account after the audit.
