Ecommerce PPC Agency
We run Google Ads for Shopify stores. First we fix the product list Google reads (your feed) and your sales tracking. Only then do we touch what you pay per click. A senior operator runs your account. Our software checks it every hour.

Written by Christopher Krassnig, Founder & CEO of ZenoX Media. Updated . The three case results come from client accounts his team runs.
An ecommerce PPC agency runs the paid ads that sell your products, mostly on Google. PPC means pay per click: you pay each time someone clicks. The work covers your product feed (the product list Google reads), sales tracking, campaign setup and bids (what you offer to pay for each click). The feed decides which searches your products can show up for.
At ZenoX, PPC means Google Ads first. On Google we run Shopping ads (a product photo, title and price), Performance Max (Google's all-in-one campaign type) and Search ads (text ads on keywords). Pinterest and Microsoft Ads run alongside. We do not run Meta, Amazon or TikTok. If you want those from one partner, a full-service agency is the better pick.

Key facts, October 2026
Results
Each result is one client account from our case studies. The numbers come from that client's own Google Ads account. Nobody outside checked them. ROAS is revenue for each €1 of ad spend, so 2.9x means €2.90 back for every €1.
We rewrote the titles on the top 80 products. Then we tagged each product (custom labels). Best sellers got their own campaign. Money-wasters got cut. Products with no sales yet got a small test budget. Not one bid changed.
Over 90 days (about 3 months).
Read the full case studyAll products sat in one Performance Max group (one set of products sharing one set of ads), so the cheapest ones took the budget. We split them into two groups, each with its own photos and headlines. Nothing new was switched on.
Over 60 days (about 2 months).
Read the full case studyMeta was the main channel. Google ran small, with nobody looking after it. We rebuilt Google and raised spend step by step. More spend usually means lower ROAS. Here both went up.
"Hands-off. Clear comms. No stress."
Over 240 days (about 8 months).

Scope
Month one fixes the base in a set order: tracking, feed, campaigns, then bid targets. After that the work is weekly, and it never stops.
Day 1
Your own Slack channel opens and you give us access to your ad account. You keep ownership of it the whole time.
Day 2
Our Shopify app goes in. It sends each order to Google straight from your store, so ad blockers cannot hide it (server-side tracking). A senior operator reads your last twelve months of data.
Day 3
Titles rewritten from real search terms. Product codes (IDs) fixed, so each sale gets matched to the right product. Errors cleared in Merchant Center. Products that spend and never sell get stopped. Then we build the campaigns.
Day 4
Campaigns run, and our hourly checks start.
Weeks 2 to 4
After big changes, Google's automatic bidding has to learn again from fresh sales. In our accounts that takes about two to four weeks. Bid targets (the return we tell Google to aim for) come last, set on clean data.
We review the search terms Google reports for your ads. Searches that spend and never sell get blocked.
We check each product. Budget moves to the ones that sell. Products that spend and do not sell get cut.
Feed updates run every day. We check Merchant Center for blocked or flagged products every week.
Our software reads the account every hour for spend spikes, feed errors and tracking breaks.
Spend, ROAS, sales and cost per sale, plus the next moves. We talk big changes through with you first.
Every step in full, with the tools behind it: how we run accounts.
Budget rules
We make this call on every account, every week. A budget only goes up when all three answers are yes.
First we work out your break-even ROAS. That is 1 divided by your margin after product cost, shipping and fees. Example: a product sells for €100 and costs you €60 all in. You keep €40, a 40% margin. Break-even ROAS is 1 ÷ 0.40 = 2.5x. Below 2.5x, each sale loses money.
Work out yours with the free ROAS calculatorPeople who search your brand name already know you. Those sales would come anyway, and counted in the main campaign they make it look better than it is. So brand searches run in their own small Search campaign, and we block brand terms inside Performance Max. The main campaign gets judged on sales from other searches.
If ROAS holds above target for 3 to 4 days, budget goes up 10 to 20%. Then we wait 2 to 4 days before the next step.
Send us your store. We read the account with you on WhatsApp.
Named reviews on Trustpilot
Copied word for word from our public Trustpilot profile on 8 October 2026.
"I expected good but they did record days, switched to a non google css and optimized the entire feed before the week was over. The support is nonstop."
"From setup to management and scaling, they've been on top of every step and helped bring a level of stability and scale to my brands that would've been impossible to achieve on my own."
"The best thing about working with ZenoX is that I literally don't have to think about or manage Google at all! They take care of absolutely everything, and their fee is very fair."

Fair alternatives
Each of these three beats us in one case. Every fact comes from the agency's own site, read on 7 October 2026.
A big US agency. Its homepage shows 160+ employees, $450M+ a year in client ad spend, and 4.8 on Clutch (a site where clients rate agencies) from 350+ reviews. It says "No long-term contracts".
Pick them if
You want a large team with a long public review record.
Watch for: No price on the homepage.
Calls itself "a media agency". It runs Amazon, ads on other retail sites (commerce media), streaming TV, Meta, TikTok and paid search.
Pick them if
You are a national brand that wants Amazon, other retail-site ads and TV in one plan.
Watch for: Its contact form starts at "Under $1 Million" a year in ad spend. It is built for big budgets.
Prints its full PPC price table. Lite is $750 a month for $100 to $5,000 in spend. Pro is $975 or 15% of spend, whichever is higher.
Pick them if
You spend under $5K a month and want a price before any call.
Watch for: Google Shopping management is only on Pro and Enterprise. Lite does not include it.

We do not run them. Hire a specialist for those and keep Google with a Google team.
