Most guides to Google Ads for Shopify stop at "install the app and click Create campaign". That's the easy part. What decides whether your first months make or lose money happens around it: whether sales are tracked once and correctly, which campaign you start with, how you size the budget, and a handful of settings that are switched on before you ever see them.
This guide walks through how to run Google Ads for a Shopify store in order, from an empty account to a first campaign you can judge after 30 days. It's written for owners doing it themselves, not agencies.
The short version:
- Meet Shopify's requirements for the Google & YouTube channel.
- Create a Google Ads account and connect it in the channel, so sales are measured.
- Make sure each purchase is counted once, as your main goal.
- Start with one campaign that matches how people find your products.
- Set a budget from your margin, not from what Google suggests.
- Review location, network and keyword settings before launch.
- Judge results after a fair period, by cost per sale.
Before you start: what Shopify requires
Shopify connects to Google through its Google & YouTube sales channel, which Google manages. It "automatically syncs your products and relevant information about your Shopify store with the Google Merchant Center", the account that holds your product data for Google.
Before you can use it, Shopify's requirements page lists a few things your store needs, including:
- An online store that isn't in private (password-protected) mode.
- A valid payment provider.
- A refund policy and terms of service on the store.
- Contact information visible to customers on a page of your store.
- Shipping to a supported country, in a currency that matches it.
Get these done first. Merchant Center has its own requirements too (Shopify mentions, for example, that your Merchant Center account needs a verified domain), and it's easier to sort them out now than while a campaign is waiting.
Step 1: Create a Google Ads account and connect it
You need your own Google Ads account. Shopify's setup guide says that "to set up Google Ads, you must have an existing Google Ads account", and the Google account you connect must be an administrator on it.
Create the account with an email you'll keep (not a personal address that might leave the business), add billing, and note the account ID. Then, in Shopify, open the Google & YouTube channel and connect it. Shopify's guide is direct about why: "Connect your Google Ads account to get conversion measurements for your ads."
Two useful details from the same page: you can connect Google Ads with or without Merchant Center, and the channel's own campaign flow sets up Performance Max campaigns. You can also create other campaign types directly in Google Ads.
Step 2: Make sure each sale is counted once
This step decides whether everything after it can be trusted. Google's automated bidding learns from the conversions you report. If those numbers are wrong, it optimizes toward the wrong thing, and your reports look better (or worse) than reality.
Three things to get right:
- One source of purchase tracking. If the Google & YouTube channel measures purchases, don't also paste a separate Google Ads tag into your theme or add it through another app for the same purchase. Google's own setup guide warns that store platforms may manage tags for you, so "ensure that you're not double-tagging your site, which can cause duplicate conversion reporting".
- Purchase as the primary goal. Google lets you mark each conversion action as "Primary (biddable) or Secondary (observation-only)" and calls getting this right "critical". Purchases should be primary. Page views, add-to-carts and sign-ups can be useful to watch, but if they're primary, bidding chases them as if they were sales.
- Real order values. Bidding toward return on ad spend needs each purchase's actual value, in the right currency.
Once the account has been running for a week, do a simple sense check: compare the purchases Google Ads reports with the orders Shopify attributes to Google for the same dates. Some difference is normal. A big gap means fix tracking before you judge anything else. Our article on Google Ads conversion tracking for Shopify goes deeper.
Step 3: Choose your first campaign
You don't need every campaign type. Start with one, learn from it, then add. The three options most stores choose between:
| Campaign | How it works | Good first choice when… | Watch out for… |
|---|---|---|---|
| Performance Max | One campaign across Google's inventory, which Google describes as "YouTube, Display, Search, Discover, Gmail, and Maps", using your product feed and assets | You have a clean product feed and want the simplest setup (it's what the Shopify channel creates) | Less visibility into where money goes; it can also show on searches for your own brand |
| Search | Text ads on Google search results for keywords you choose | People search for specific products or problems you solve, and you want control over which searches you pay for | Keyword matching is looser than it looks (see step 5) |
| Shopping (standard) | Product ads with image and price, from your Merchant Center feed | You sell products people compare on price and looks | Feed quality matters: titles and images decide which searches you show for |
There's no universally right answer. A store with a well-known brand name might start with a small Search campaign on its brand and core products. A store with hundreds of products and a strong feed may start with Performance Max. What matters is that you know which one you're running and why, and that you don't run three overlapping campaigns on a small budget, where they compete for the same searches.
Step 4: Set a budget from your margin
Google Ads asks for an average daily budget per campaign. If you think in monthly terms, Google's guidance is to divide your monthly budget by 30.4. Spend varies from day to day around that average.
Rather than taking Google's suggested amount, work out what a sale is allowed to cost:
Break-even cost per sale ≈ average order value × gross margin
A worked example with made-up numbers: your average order is $60 and your gross margin (after product cost and shipping) is 45%. Each order leaves $27, so a sale can cost up to about $27 in ads before you lose money on it.
Now size the test. Automated bidding needs conversions to learn from, so a budget that buys only one or two sales a month teaches it very little. If you aim for at least 30 sales in the first month at roughly break-even, that's 30 × $27 = $810, or about $27 a day. If that's more than you can risk, start smaller but expect slower, noisier learning, and judge over a longer period.
Two cautions: a bigger budget won't fix a campaign that's leaking money (it leaks faster), and repeat customers can make a sale that loses money on the first order profitable over time. Use your own numbers here; there's no reliable "average budget" for a Shopify store.
Step 5: Review these settings before you launch
New campaigns come with defaults that widen who sees your ads. None are wrong in every case, but each should be your decision:
- Locations. Google's default location option, "Presence or interest", also reaches people outside your target countries who have shown interest in them. If you only ship to certain countries, read why Google Ads shows in the wrong country before launching.
- Networks. Google says that for Search campaigns, "search partners are included by default". They're other sites that show search results. Leave them on if you like, but plan to compare their cost per sale with Google Search after a month.
- Keyword match types. Google states that "broad match is the default match type". Broad match can show ads on searches related to your keyword's meaning, which is wider than many owners expect. Phrase match ("quotes") and exact match ([brackets]) are narrower.
- Auto-applied recommendations. Google can apply some recommendations automatically if the option is on. Check under Admin → Account settings → Auto-apply, and decide which you're comfortable with.
Step 6: What to watch in the first 30 days
The first weeks are noisy. Resist changing things every day: frequent changes make it hard to tell what worked. Instead, check weekly:
- Search terms (for Search and, where available, other campaigns): what people actually typed. Add negative keywords for searches that could never buy.
- Cost per sale against your break-even, by campaign.
- Tracking agreement between Google Ads and Shopify.
- Where spend went: locations, networks and, for Performance Max, the reports Google provides.
After 30 days, you'll have enough to decide whether to keep going, adjust, or stop. Our guide to where Shopify stores lose Google Ads budget explains what to look for when results disappoint, and if your account is new, the guide to checking a new Google Ads setup covers the early warning signs.
Get your setup checked
When your first month is done, you can get a measured second opinion. Advizify runs a read-only audit of your Google Ads account for Shopify stores: it measures wasted spend over the last 30 days, ranks what to fix first, and never changes your campaigns. Your first audit is free, and later audits are $19 each.
FAQ
Can I run Google Ads from inside Shopify? Partly. The Google & YouTube channel connects your Google Ads account, syncs products to Merchant Center and offers a Performance Max campaign setup. For other campaign types and most settings, you'll work in Google Ads itself.
Do I need Google Merchant Center? For Shopping and product-based Performance Max campaigns, yes: it holds your product data. Shopify notes you can connect Google Ads with or without Merchant Center, for example if you only run Search campaigns.
How long before Google Ads works for a new store? Expect the first few weeks to be a learning period. Judge results over at least 30 days, longer if you get only a few sales a week, and by cost per sale rather than clicks.
What's the minimum budget for Google Ads on Shopify? There's no official minimum. Work back from your break-even cost per sale and the number of sales you need to learn anything, as in the example above.
