Most small-business websites do not fail loudly. They load, the photos look nice — and they quietly hand customers to commission-charging platforms and drop off mobile phones before the page finishes loading. Nothing looks broken, so nothing gets fixed.
The losses are real, and they are measurable. Here are three of them — and a free way to see how your own site scores at the end.
1. Every sale a middleman closes costs you a commission
The most clearly measured version of this is hotels and online travel agencies, so we will use it as the worked example — but the pattern is the same wherever a platform sits between you and your customer. When a guest books through an online travel agency, the hotel pays for it. Booking-engine vendor Exely puts OTA commissions at 15–30% of every room booking. On a €120 room, that is €18–36 handed over on a single night — and it repeats every time that channel books instead of the hotel's own site.
Your own website is the one channel where no middleman takes a commission on the sale — though booking and payment providers you connect still charge their own fees. It does not have to replace the platforms — they bring you customers who would never have found you. But every sale you shift from a middleman to your own direct channel is a share of that middleman's commission you no longer pay. That only happens if your site is fast enough to hold the visitor, trustworthy enough to close them, and findable enough to reach them in the first place.
2. Speed costs you customers continuously, not just past three seconds
The most rigorous measurement of what speed is worth was run by Deloitte Digital and 55, commissioned by Google. They tracked 30 million user sessions across 37 brand sites — real users, not a lab simulation — and found that after a 0.1-second improvement across four mobile speed metrics, conversion in travel and booking rose by 10.1% ("Milliseconds Make Millions", 2020).

One honest caveat, because it matters: those 37 sites were enterprise brands. What transfers to an owner-run small business is the shape of the finding — that conversion keeps responding to speed in tenths of a second, well inside the range everybody already calls "fast enough". The exact 10.1% does not transfer, and we are not going to pretend it does.
Speed is the loss nobody feels, because the people who leave never contact you. Vendors and auditors have long used three seconds as the point where the damage becomes obvious: a Ryte and HubSpot audit guide cites 40% of users leaving a site that takes longer than that (Ryte + HubSpot, undated, about 2020 — an older figure, and we cite it as one), and Exely's guide sets under three seconds as its loading target. Treat three seconds as the floor, not the goal. The Deloitte measurement is the reason why: the returns do not stop once you clear it.
How fast is fast enough? Our own target for a small-business website is under 1.5 seconds for Largest Contentful Paint — the moment the main content appears — on a mobile phone. Google's published "good" threshold for the same metric is 2.5 seconds. Three seconds is where abandonment becomes severe — it is not where the improvement stops paying.
Here is the trap most owners fall into. When you run a free speed test, you get several scores, and it is easy to read the wrong one. We have watched an owner see a 92 for SEO and conclude the site was fine — while the Performance score, the one that actually measures how fast the page loads for a visitor, was the real problem. If you only remember one thing: the number that costs you customers is Performance, not SEO.
3. Search engines — and now AI — cannot recommend a site they cannot read
The way people find local businesses is changing. Increasingly, a customer asks an assistant a question — "where should I stay near Kommeno Bay?" — and gets a short list of named businesses, assembled from sites the assistant could actually read.
If your site has no structured data telling search engines what it is — what you do, in which town, with which services, at what rating — you are relying on the machine to guess from your sentences alone. Structured data does not by itself get you into an AI-generated answer: Google says generative AI search needs no special schema.org markup. What it does is state those facts in a format search engines read directly, and help a page qualify for Google's rich results.
There is a quieter version of this loss, too. A business that is absent from an AI recommendation gets no error, no bounced email, no analytics blip — it simply never comes up. You cannot see the customer you never appeared to.
The thread connecting all three: trust
Speed, direct sales and being findable all sit on top of one thing — whether the site reads as honest. An academic study of 450 consumers found that transparency and ethical marketing together explain 62% of digital-brand trust in that model, with ethical marketing the single strongest predictor.

For an owner-run business, that is good news. A business with real history, real people and honest pricing has the trust story most chains cannot buy — but only if the website surfaces it instead of hiding it behind a generic template.
What to do about it
You do not need to rebuild everything this week. You need to know which of these three is actually costing you, and by how much. In order:
- Check your Performance score — not your SEO score — on your homepage and one key page.
- Look for structured data. It states what your business is instead of leaving search engines to infer it from your sentences.
- Count the sales you close directly against the ones a commission-charging platform closes for you for one month. That ratio is the size of the prize.
Common questions
How much commission does Booking.com take?
Online travel agency commissions generally run 15–30% of each booking (Exely, undated vendor guide). The exact rate varies by platform and market, but every OTA booking costs you a share of the room rate that a direct booking on your own site would keep.
How fast should a small-business website load?
We aim for the main content to appear in under 1.5 seconds on mobile — our own target, tighter than Google's published "good" threshold of 2.5 seconds for Largest Contentful Paint. A Google-commissioned Deloitte study measured a 10.1% conversion gain in travel after a 0.1-second improvement across four mobile speed metrics, on 30 million sessions from 37 enterprise brands — the shape of that finding transfers to a small business more confidently than the exact number. Three seconds is the point where abandonment becomes severe (Ryte + HubSpot put it at 40% of users, undated, about 2020), not the point where improvement stops paying.
Why is my business not showing up in AI search results?
A machine cannot recommend what it cannot read. Structured data states what your business is in a format search engines read directly, and clean markup keeps the page legible to a crawler. Neither guarantees a place in an AI-generated answer — Google says generative AI search needs no special schema.org markup.
Is a high SEO score enough?
No. The score that measures how fast your page loads for a visitor is Performance, a separate number from SEO. A strong SEO score with a weak Performance score still loses customers.
