They're grouped into four blocks. The first six cost nothing to fix and explain most of
the difference.
Block A — Trust (why they don't buy from you)
1. Is it obvious who you are and where you are? Company name, city, a
real phone number and an address that exists. A store with no verifiable location is
fighting distrust before it ever fights on price.
2. Are your policies visible before checkout? Shipping, returns and
warranty belong on the product page, not buried in a footer link. If the customer has
to hunt for it, they leave.
3. Do you have real social proof? Reviews with a name, a photo or at
least a date. Five anonymous testimonials with stock photos subtract credibility instead
of adding it.
Block B — Clarity (what you sell and for how much)
4. Do they get it in 5 seconds? Show your homepage to someone who
doesn't know your business and ask what you sell, to whom and at what price. If they
hesitate, the problem is at the top, not the bottom.
5. Is the price the final price? Taxes and shipping appearing at the
end of checkout is the number one cause of abandonment. Customers don't get upset about
the amount: they get upset about the surprise.
6. Do your photos show scale and context? Product on a white background
tells nobody size, texture or use. Three good photos outsell fifteen mediocre ones.
Block C — Friction (why they leave at the last step)
7. Does shipping cost appear before you ask for the email? If you force
a signup to reveal shipping cost, you lost the customer halfway down the funnel.
8. Can they buy without creating an account? Guest checkout, always.
Mandatory registration is a wall you built for yourself.
9. Are the payment methods your customer actually uses? If you sell into
the US and only accept a local bank transfer, your store isn't broken: it's incomplete.
International cards, PayPal, or whatever that market pays with.
Block D — Speed and mobile (where sales vanish silently)
10. How heavy is your homepage? Open the site on a phone using mobile
data, not wifi. If the product takes more than three seconds to appear, half your
visitors never saw it.
11. Is the buy button within thumb reach? Check on a real phone, not the
browser simulator. Some buttons technically exist and functionally cannot be tapped.
12. Do search and filters actually work? Search an exact product name
and see if it comes up first. If search fails, users assume you don't stock it.
Keep the order: trust → clarity → friction → speed. Fix speed before
trust and you're just making a faster store that nobody buys from.
