Best Google Ads Tools for Shopify in 2026

What a Shopify store needs from a Google Ads tool

Here are 3 common places a Shopify store loses money on Google Ads. A good tool watches all 3 for you.

1. Sales counted twice. Google says a single action "can be counted more than once if you have multiple Google tags set up" (Google Merchant Center Help). A Google tag is the code that tells Google Ads a sale happened. Google names a second cause: you "had already set up conversion tracking before installing the Google & YouTube app." Google warns that duplicate tags "can cause inaccurate report data." Google Ads can then show more sales than Shopify, so your results look better than they are.
2. A weak product feed. Your feed is the list of products, prices and titles Google uses for Shopping ads (the product ads with a photo and a price). It sits in Merchant Center. Google describes Merchant Center as "a free tool" that puts your products in front of shoppers (Google Merchant Center Help).
3. Spend with no sales. Search terms (the words people typed into Google), products and campaigns that cost money and never sell.

The 6 tools below are ranked from free to paid. PerfoAds is our own tool, and we hold it to the same rules.

"Not stated" means the vendor's page doesn't say it. The tool may still have it.

Whatever tool you use, its changes land in your Google Ads account. There, Google lets you "undo most types of changes that were made in the last 30 days" (Google Ads Help).

Google & YouTube app

What it does. This is Google's own Shopify app, made by Google LLC. It launched on the Shopify App Store on November 28, 2017. Its listing says it can "sync your products, deals, and shipping to Merchant Center." It also runs "Performance Max ads across properties like Search and YouTube." Performance Max is a Google campaign type that shows your ads across Google's channels, "including YouTube, Display, Search, Discover, Gmail, and Maps," from 1 campaign (Google Ads Help). The listing names conversion tracking too.

Price. "Free to install. Additional charges may apply." The ad spend is "billed directly to your Google Ads account."

Strengths. It's free and made by Google. It had 5,594 reviews on its listing when we checked. Inside Google Ads, the Optimization score adds suggestions. Google calls that score "an estimate of how well your Google Ads account is set to perform" (Google Ads Help).

Limits. The listing doesn't state audits, alerts on wasted spend or an approval step. If you set up tracking before installing it, check for double-counted sales (see point 1 above).

Best for. Every Shopify store, as step 1, since it gets your products into Merchant Center.

Avisos

What it does. Avisos is a free Shopify app that "audits and monitors Google Ads accounts to identify wasted spend, conversion tracking issues" and more. It sends "alerts for issues impacting ROAS, lead quality, search term quality, campaign structure, and geographic targeting." ROAS (return on ad spend) is the sales you get back for each $1 of ads.

Price. Free on the Shopify App Store.

Strengths. It costs nothing and installs from your Shopify admin. Its listing says it also works with Google Analytics and Meta Ads.

Limits. It launched on May 22, 2026 and showed "0.0 (0 Reviews)" on our visit. Its own website wouldn't load for us, so every fact here comes from the Shopify listing. It doesn't state a check count, how often alerts run, an approval step or undo.

Best for. A store that wants a free second opinion. It's too new to judge on results.

Opteo

What it does. Opteo scans Google Ads accounts "for statistically significant patterns" and lines up improvements. You push each one "live to your Google Ads account in a few seconds."

Price. Basic is $129 a month for up to 10 accounts and $25,000 in monthly ad spend. Professional is $249 for 25 accounts and up to $100,000. Paying yearly gives a 2-month discount.

Strengths. Under $25,000 in monthly ad spend, it's the cheapest paid tool here for 1 store. Its site lists "Manage Shopping Ads" and Slack alerts. 10 accounts on Basic means a brand running 3 shops still pays $129, if their total spend is $25,000 or less. If you're unhappy, Opteo says it will "refund your most recent invoice."

Limits. Its pricing page describes plans for Google Ads (Opteo pricing). Its help center says you can also link "Microsoft Ads, Meta, LinkedIn, or TikTok" accounts (Opteo help). The pricing page doesn't say what those cost. Basic refreshes data once every 24 hours. Opteo's pages don't state Merchant Center support, a check count or undo. The trial is 14 days.

Best for. Stores spending under $25,000 a month that want a short list of improvements to click through.

PerfoAds

What it does. PerfoAds says it's "built for Shopify and other online stores." Each month it runs 166 automatic checks on your account, plus an AI review of your biggest campaigns, and gives you a score out of 100. The checks cover tracking, budgets, search terms, Performance Max, Shopping and your product feed. Once you turn on monitoring, it sends a daily alert at 06:00 UTC when spend spikes, tracking breaks or ads get disapproved.

Price. $149 a month per Google Ads account, billed monthly, whatever the account spends. Cancel anytime, with no contract. Money-back not stated.

Strengths. Nothing in your account changes until you say yes. Fixes come with a preview, and you can roll back most changes PerfoAds makes for 30 days. Approve and undo are both in beta. Its Feed Optimizer reads your products from Merchant Center and can rewrite up to 1,000 product titles a month. Support replies come from the founder, Pawel Wilk.

Limits. There's no free trial. It works with Google Ads only, not Meta or Microsoft. You can add 10 accounts at most, at $149 each, so 3 shop accounts cost $447 a month. One-click Apply Fix, which writes an approved change into Google Ads for you, is in beta and opt-in. The push of new titles to Merchant Center is in beta too.

Best for. A store owner with 1 or 2 shops who wants daily checks, better product titles and no change made without a yes.

Adalysis

What it does. Adalysis promises you can "audit your accounts in minutes with 100+ prebuilt checks." It adds "24/7 monitoring," with critical alerts by email or Slack.

Price. Up to $50K in monthly ad spend, it's $149 a month, or $126 a month billed yearly. Every plan has the same features, and the price rises with spend.

Strengths. Unlimited Google Ads accounts, Microsoft Ads accounts and users on every plan. So 3 shops under $50K total spend still cost $149. The free trial is 30 days. It names Performance Max tools.

Limits. Its pages don't state feed tools or a Shopify link. It does flag Shopping search terms that waste spend. It says it needs your permission to change your account, but auto-resolve rules you turn on act alone. You can undo what they did from its Auto resolve log.

Best for. A brand with several stores on Google and Microsoft that wants deep checks for 1 price.

Optmyzr

What it does. Optmyzr is a full ad management platform. Its main audit "will run daily in the background," and it has 3 prebuilt templates for Shopping feed audits.

Price. Priced by ad spend. Its lowest tier is $25K. Its store tools ("Shopping / PMax Retail Campaign and Feed Management") come only on Premium: $389 a month at $25K spend, or $272 a month billed yearly. Essentials is $299 a month without them.

Strengths. Optmyzr promises "No changes without your approval, ever." Its site lists Google, Microsoft, Amazon, Meta, LinkedIn and more. On Premium, the account count is unlimited, with a fair usage policy. The trial is 14 days, and it offers a 30-day money-back guarantee for first-time plans.

Limits. For 1 store, it costs about 2.6 times PerfoAds' $149 (Premium, monthly). A scheduled rule in its Rule Engine, its if-then automation tool, "will automatically apply the changes" if you set it to. Its help center says "you can't undo changes made by optimization in Optmyzr," so you revert them in Google Ads change history. More on this in PerfoAds vs Optmyzr and Optmyzr alternatives.

Best for. Agencies running many store accounts across several ad platforms.

What each tool costs at your ad spend

Monthly list prices for 1 Shopify store, billed monthly. Optmyzr's lowest tier is $25K, so its price doesn't drop below that. Above $25,000, Opteo moves to Professional at $249 and Optmyzr Premium rises to $454. Adalysis stays at $149 up to $50,000. PerfoAds stays at $149 at any spend.

Now set the price against your ad budget. At $2,000 a month in ads, $149 is about 7.5% of what you spend. At $10,000 it's about 1.5%. A paid tool earns its place when it finds more waste than it costs. Work out the ROAS you need to break even with the break-even ROAS calculator.

How to pick in 4 questions

1. Are your products in Merchant Center yet? If not, install the Google & YouTube app first. Feed tools need that product list.
2. Do Google Ads sales match Shopify orders? If Google shows more, fix tracking before you buy anything. Check Add to Cart too. A primary conversion action is one Google treats as a main goal. Google reports those in the "Conversions" column and uses them "for bidding" (Google Ads Help). So if Add to Cart is primary, a cart counts like a sale. See when Add to Cart is counted as a sale.
3. How many stores do you run? For 1 store under $25,000 in ad spend, Opteo is the cheapest paid pick at $129. PerfoAds and Adalysis come next at $149, and Adalysis drops to $126 a month if you pay yearly. With 2 shops, Opteo and Adalysis cost less than PerfoAds while the shops' total ad spend is $100,000 a month or less, since they don't charge per account. 2 shops on PerfoAds cost $298.
4. Do you want to approve every change? PerfoAds and Optmyzr state an approval step (PerfoAds' is in beta). Adalysis says it needs your permission, and you fix issues yourself unless you turn on auto-resolve rules. Opteo has you push each change. The 2 free apps don't state one.

FAQ

What is the best Google Ads audit tool for a Shopify store?

For free, Avisos is a Shopify app that checks wasted spend and tracking, but it's brand new. For paid, PerfoAds is built for online stores, runs 166 checks and reads your Merchant Center products. Under $25,000 in monthly ad spend, Opteo is cheaper at $129 and has Shopping Ads tools.

Is Google Ads software worth it for a small Shopify brand?

It depends on your ad spend. At $2,000 a month in ads, a $129 to $149 tool is about 6.5% to 7.5% of your ad budget. Start with the free Google & YouTube app and a free check. Pay for a tool once the waste it finds each month is bigger than its price.

Is the Google & YouTube app enough on its own?

For getting products and Performance Max ads live, yes. Its listing doesn't state audits, waste alerts or an approval step. Add a checking tool once you spend steadily.

Why does Google Ads show more sales than Shopify?

Often because 2 Google tags count the same order. Google says this happens with "multiple Google tags," or with tracking set up before the Google & YouTube app (Google Merchant Center Help). Remove the extra tag, then compare again.

Is there a Google Ads AI assistant for an online store?

Several of these tools have one. Optmyzr lists an "AI Sidekick Assistant" and MCP access for Claude and ChatGPT. MCP is a way to plug your ad data into an AI chat app. Adalysis has an "Adalysis MCP" to "connect live account data with AI." PerfoAds gives each account 1,000 AI credits a month for ad text, campaign checks, product titles and questions. Opteo has Chat, which it calls "your AI co-pilot inside Opteo" (Opteo help). Its Opteo MCP works with "Claude or ChatGPT" (Opteo help).
