The short answer: a website that gets visitors but not sales almost always has one of six measurable problems — it's slow on phones, it excludes some visitors, it can't be found for the right searches, it doesn't look safe, it fails to reassure people at the exact moment they'd buy, or nobody vouches for it. None of these are mysteries. All of them can be checked.
When sales are missing, most owners are told one of two stories: "you need more traffic" (so buy ads) or "you need a redesign" (so buy a website). Both are sometimes true — and both are usually premature, because they skip the diagnosis. Below are the six lenses we grade every site with, translated into the symptoms you can spot yourself, today, without any tools.
Lens 1 — Speed: the silent checkout killer
Your site is slower on a real phone than you think
You browse your own site on fast wifi with everything cached — the best case it will ever have. Your customers meet it cold, on a phone, often on a weak connection. Slow pages don't get complained about; they get abandoned.
Spot it yourself: open your busiest product or service page on your phone with wifi off. Count seconds until you could actually tap "buy." If you got impatient, so do strangers with no loyalty to you.
Lens 2 — Accessibility: the customers you can't see leaving
Some visitors literally cannot use your site
Low-contrast text, buttons that don't work from a keyboard, images without descriptions, forms without labels — each one quietly turns away real customers (and their households), and raises legal risk on top.
Spot it yourself: try to add a product to your cart using only the Tab and Enter keys. If you get stuck, a meaningful group of your visitors is stuck too. Our plain-English ADA check goes deeper.
Lens 3 — Findability: invisible to the people already searching
You rank for your name, but not for your problem
Most small-business sites are findable by people who already know the business exists — and invisible for the searches buyers actually make ("[what you sell] near me", "best [category] for [need]"). Increasingly that includes AI assistants, which answer questions directly and only mention businesses they can read and verify. That's the newer half of findability — see What is AEO?
Spot it yourself: search for the problem you solve — not your name — in a private browser window. If you're not there, this lens is costing you customers who were actively looking.
Lens 4 — Security signals: the browser gets a vote
"Not secure" warnings end purchases instantly
Expired certificates, mixed-content warnings, or a checkout that looks different from the rest of the site all trigger the same customer response: close the tab. Browsers and payment providers actively warn people away from sites with weak security hygiene.
Spot it yourself: look at the address bar on every step to checkout. Any warning, any "not secure," any surprise domain change — that's where trust dies.
Lens 5 — Trust at the buy moment: reassurance in the wrong place
Your credibility exists — but not where doubt peaks
This is the most common finding in the sites we grade: the business has real credentials — warranties, policies, years of service — buried in the footer, while the product page (where the buying decision happens) shows nothing. Doubt peaks at the buy button; reassurance has to live there too.
Spot it yourself: open your key product page as a stranger and ask: within one screen of the buy button, what tells me this purchase is safe? Returns? Guarantee? Real reviews? If the answer is "nothing," you found the leak.
Lens 6 — Reputation: nobody vouching for you
Buyers check what others say — before they believe you
Missing reviews, an unclaimed business profile, or a stray one-star complaint with no response all shape the decision before your site even loads. Reputation isn't vanity — it's the second website every buyer visits.
Spot it yourself: search "[your business] reviews." What a stranger finds in ten seconds is your real first impression.
The order matters: measure, fix, then (maybe) redesign
Ad spend multiplies whatever your site already does — including the leaks. A redesign rebuilds the container without necessarily fixing the contents. The cheap, boring, correct order is: measure the six lenses, fix the ranked problems, then decide whether you need more traffic or a new design at all. Most sites we grade need two or three specific fixes, not a reinvention.
One honesty note, because it's how we work: a self-check like the ones above is an estimate. A real diagnosis is measured. When we grade a site, every number is labeled Measured or Estimated — and we never dress one up as the other. Here's exactly how the grading works.
Common questions
My website gets traffic but no sales — what's wrong?
Traffic without sales means the problem is on the site, not in the marketing. The usual suspects, in order of frequency: slow mobile pages (Lens 1), missing reassurance next to the buy button (Lens 5), and a confusing or broken path to purchase. Walk your own checkout on a phone as a stranger before spending another dollar on ads.
Should I redesign my website if it isn't converting?
Usually not first. Most conversion problems are specific and fixable — and a redesign can carry the same problems into a prettier wrapper. Measure first; redesign only if the structure itself is what's broken.
How do I find out what's actually broken?
Get a measured reading rather than a guess: real speed measurement on a phone connection, an accessibility check, a search-visibility read, and a stranger's walk of your buying path. The Grader does the first pass free, across all six lenses, in plain English.
