Use case
See the ad. Then open the page.
The library shows the creative. The product page shows what the click lands on. The calculator shows the return the sale has to clear.
How to use the free tools
Open the libraries for that store
Paste a Shopify store into the winning ads spy. It opens the Meta Ad Library, the TikTok ad library, and Google Ads Transparency for that brand. You see public creatives. Spend is not shown, and the tool does not invent an ad count.
02Audit the page the ad is selling
Take the product URL from the ad and run the CRO Audit. You want the price, the variant, the buy button, and whether add to cart dumps the shopper onto the cart page. A weak page wastes a good creative.
03Know the return before you scale
The ROAS calculator turns price and costs into the return a sale needs before ads pay for themselves. The profit calculator adds CPM, click rate, and conversion so you can see profit per sale. The numbers stay in your browser.
04See what the landing page is running
Reviews, upsells, subscriptions, and chat often change how a click converts. The app detector lists the storefront apps and links them to the App Store. It is context for the test, not a media plan.
Libraries are public. Spend is not.
Checkout Club does not show ad spend, ROAS from the ad account, or which creative is the winner. You still read the libraries yourself.
A CRO score is not a conversion rate. Use it to see what the page is doing, then decide the test. The calculators are arithmetic on the numbers you type.
Questions
Can I see how much a brand spends?
No. The ads spy opens the public libraries. Spend, results, and audience are not in those pages, and Checkout Club does not add them.
How do I judge the landing page?
Paste the product URL into the Shopify CRO Audit. Read the findings on price, variants, the buy button, and the cart. Then decide if the page can hold the traffic.
Where do I get a break-even ROAS?
Use the ROAS calculator or the profit calculator with your price and costs. The result is math, not a quote from the ad account.
Does this replace an ad account?
No. It is the public side: libraries, the storefront, and the numbers you type. Buying and scaling still happen in the ad platform.
