Stop paying for ads on products you can't sell.
Guardian checks your Shopify store, Google Merchant Center, Google Ads and Meta Ads every morning. If something is wasting money, you get one short email that says what broke, how much it is costing and what to fix first.
Your feed, your ads and your stock don't talk to each other.
Shopify knows what is in stock. Merchant Center knows what is approved. Google and Meta know what they spent. Nobody puts the three together, so a product that sold out on Friday can keep collecting clicks all weekend, and a broken pixel can go unnoticed for days while smart bidding learns from bad data.
Six leaks that cost stores money every week.
Products that Merchant Center still shows as in stock while Shopify has zero units. You pay for clicks that can never convert.
New disapprovals and warnings in Merchant Center, with the products affected and how much they sold last month.
Campaigns, ad sets and products that keep spending in Google Ads or Meta Ads without a single order in Shopify.
Days when Shopify records orders but the ad platforms record none. Smart bidding is flying blind until you fix it.
Spend that jumps above your usual daily pace before the month is gone.
Products that sold well last month and have stopped getting impressions.
Two minutes to set up. Read-only.
- Install the app from the Shopify App Store.
- Connect Merchant Center, Google Ads and Meta Ads with read-only access. Guardian never changes your campaigns.
- Get one email each morning, only when there is something worth your time.
I'm Álvaro García. I have spent 15 years running paid media for brands like L'Oréal, Primor and Maserati, and today I manage Google and Meta ads for Shopify stores at Sellencia, my agency in Spain.
Guardian started as the checklist we run every morning on the stores we manage. I'm turning it into an app so any store can have it without hiring an agency.
Join the waitlist.
Founding stores use Guardian free during the beta and keep a founder price afterwards. Your answers help me decide what to build first.
You're on the list.
I'll write to you personally before the beta opens. If you reply to that email with your biggest headache, it goes straight to the top of the build list.
Before you sign up.
Will Guardian change my campaigns?
No. It only reads data. Every alert tells you what to fix, and you decide whether to do it.
When does it launch?
The beta opens to the waitlist first, in small groups, starting with stores that already spend on both Google and Meta.
How much will it cost?
It is free during the beta. After that there will be simple monthly plans billed through Shopify, and founding stores keep a lower price.
Do I need an agency to use it?
No. Guardian is built for store owners and in-house marketers. Agencies can use it too.
