Google Ads for Shopify Apps: The Agency Playbook

Shopify ads is a red ocean. Every app bids on the same store searches, and prices keep climbing. Google is the blue ocean: bigger volume, cheaper clicks, and most of your competitors aren’t there. Here’s the playbook we run at Convert2x.

Short answer: Google is the blue-ocean channel for Shopify apps. More volume, cheaper clicks, fewer competitors than the app store. Skip Shopify’s brand with a full ecommerce-platform negative list, launch on manual CPC to build ~30 conversions (report install, subscribe, and payment to get there three times faster), then switch to value-based AI bidding fed per-keyword revenue. Expect to return at least media cost inside a three-month test.

Step 1 — Solve the Shopify-brand problem

Shopify prohibits apps from bidding on its brand. The clean solve: don’t. Run a comprehensive negative-keyword list of every other ecommerce platform, and generic queries like “inventory app for ecommerce” resolve to overwhelmingly-Shopify searchers without you ever bidding the word.

Step 2 — Start manual, build conversion volume

AI bidding needs ~30 conversions before it works. Start on manual CPC with your top 15–20 keywords. Accelerator: report three funnel events per merchant — install, subscribe, payment — instead of payments only, and you hit the threshold three times faster.

Step 3 — Switch to value-based AI bidding

Optmyzr’s research across thousands of accounts: Maximize Conversion Value campaigns ~575% ROAS versus ~137% for manual CPC. The catch: the AI is only as good as the values you feed it. Send per-keyword conversion values with click IDs — installs, subscriptions, payments, each with its revenue — via Prys. Then expand into PMax and AI Max.

Step 4 — Landing pages where required

Some keywords can’t run to the Shopify domain. Build a compliant landing page; attribution survives end to end if your tracking covers it.

The timeline

Plan on a 3-month test: M1 manual launch, M2 conversion reporting + first Maximize Conversion Value test, M3 scale what returns. We expect to return at least the media cost within the test window. Past result, 563% ROAS at $0.07 average CPC.
