A sneak peek at tests that actually moved the needle

Test #42

CART PAGE

Remove all distraction in cart. No social proof, no colors or discounts

What format is the checklist in?

How do I know these tests actually worked?

It’s a Google Sheet. You’ll get a view-only link and instructions to make your own copy—so you can edit, sort, and prioritize tests as you go.

Every test in the list has been personally run by me (Lucia), usually multiple times across different brands. These aren’t scraped ideas... they’re real. (although I can't always show the client, I always share a visual example of what it looks like). 

Who is this checklist for?

Can I get a refund if it’s not what I expected?

It’s made for junior to mid-level CROs working in eCommerce—especially if you’re running tests solo, freelancing, or inside a small team and need proven ideas fast.

Sure. This has never happend before honestly. Bút if you are unhappy: let's talk. I'd rather hear you out and get you your money back, than be greedy and take those bucks from you.
