Mobile version of a website: a phone checklist
Robert MirovUpdated Sep 5, 2026
Most leads in Tashkent come from a phone. A site that is “fine on a monitor” and broken in the hand are two different things. This article is acceptance on your smartphone, not a PageSpeed report and not an argument about Lighthouse scores. Speed and Core Web Vitals are in a separate guide. Here: get through on a call, write in Telegram, submit a form, not miss with a finger, not wait forever on 4G. UZNEO accepts sites like this: open from a phone in the office and in a taxi — and walk the list below.
01Why accept from a phone, not from a screenshot
The contractor shows a 1440 px mockup. The client is riding along Amir Temur, one hand on the rail. If the “Call” button is tiny and the form has eight fields — the person closes the tab.
Acceptance = your phone, your carrier, incognito / without office Wi‑Fi at least once.
| Before | After | |
|---|---|---|
| “Desktop is fine” | A phone checklist in the contract | |
| A screenshot from Figma | A live URL on 4G | |
| Fixes “later for mobile” | Mobile is a handover criterion |
02Phone: `tel:+998`, not a picture of the number
The number must be a `tel:+998…` link. A tap opens the dialer. A “call us” picture with no link — a person will not copy digits in traffic.
International format: `+998 90 …`, not “90-xxx” without a country code — some phones will not understand it.
Check:
• header / first screen — a clickable number;
• footer — the same number, not another one “for looks”;
• no `onclick` only on desktop.
Ads often send mobile traffic. If `tel:` is dead, you pay for a click with no call. Call conversions — call tracking.
| Before | After | |
|---|---|---|
| Number as text / a picture | `tel:+998…` | |
| Different numbers in header and footer | One current number | |
| Tap does “nothing” | The dialer opens |
03Telegram and WhatsApp — where the button leads
A messenger button must open a specific chat or bot, not the telegram.org homepage. Check from a phone: whether the app launches, no 404, not “user not found”.
One main channel + a backup. Three icons in a row with no priority — the finger taps at random.
A tag in the link (`?start=` on a bot, UTM on the site) if you count leads. The button as a conversion — a separate article.
| Before | After | |
|---|---|---|
| An icon “for looks” | A working dialog in 1 tap | |
| Three messengers equal | One main | |
| No tag | Clear where they wrote from |
04Form: fields, keyboard, where it goes
On a phone the form breaks more often than “the design”.
☐ Few fields: name + phone (+1 for the job). The rest — a manager will ask.
☐ On the phone field, `inputmode` / `type` so a numeric keyboard opens.
☐ The “Submit” button is not covered by the keyboard and is visible without a hunt.
☐ After submit — a clear screen, not an empty reload.
☐ A test lead reached email / CRM / the manager’s Telegram.
☐ No captcha that you cannot pass on a phone.
If the form is “later” — at least `tel:` and messenger work. Otherwise the site does not take leads — why a site gives no leads.
| Before | After | |
|---|---|---|
| 8 fields “for statistics” | 2–3 fields | |
| Letter keyboard on the phone field | Digits for +998 | |
| “Sent” into nowhere | A test reached a person |
05Buttons under the thumb
The thumb zone is the bottom of the screen and large targets. Tiny footer links, a 12 px “close”, two CTAs jammed together — misses.
☐ The main CTA (call / write / lead) is visible without scroll or is pinned.
☐ Button height is enough, not a “thin line”.
☐ The menu opens and closes; it does not cover the form forever.
☐ Cookie / banner does not lock the phone dead.
☐ Map: you can open it in a maps app, not only a tiny iframe.
A landing for ads — structure and conversion.
| Before | After | |
|---|---|---|
| CTA after three screens of text | CTA on the first screen | |
| 10 px links | Large buttons | |
| A banner on the whole screen | You can close it and call |
064G, not office Wi‑Fi
One pass on 4G (or “modem mode” from a phone). Look not at the PageSpeed score, but at the feel: the first screen appeared, you can tap the CTA, images do not take a minute.
Typical in UZ: heavy photos “as shot at 12 MP”, autoplay video, fonts from six files, a slider of 15 frames.
If the page “spins” longer than a person will wait in a queue — cut the media. LCP numbers are in PageSpeed; here a verdict of “usable” is enough.
| Before | After | |
|---|---|---|
| Check only in the office | One run on 4G | |
| Hero video 40 MB | A photo / a short preview | |
| “Score 90, but the button after 8 sec” | Action first, score later |
07A 10-minute checklist — print it into the brief
Open the site from a phone, incognito, 4G:
1. The first screen is clear: who you are and what to do.
2. `tel:+998` opens the dialer.
3. Telegram / WhatsApp opens the right chat.
4. Form: few fields, numeric keyboard, the lead arrived.
5. The CTA is not tiny and not hidden.
6. The menu does not break the page.
7. Text is readable without pinch-zoom (except the map).
8. No horizontal scroll (except tables — better simplify).
9. SSL, no browser warning.
10. A service page, not only home — the same set of actions.
Put the same into a brief before the contract. Domain and HTTPS — hosting and mail.
Build a site that passes this list — website development / landing.
08What is not in this checklist
Intentionally not here: PageSpeed scores, Schema, hreflang, keyword density. That is SEO and speed as lab metrics.
Here — can a person leave a lead from a phone. If not — ads and SEO are pointless until you fix fingers and the form.
| Before | After | |
|---|---|---|
| “It is responsive, green in DevTools” | Walked the list on a live phone | |
| Handed over from a desktop screenshot | Handed over on 10 points | |
| Mobile = a shrunk desktop | A separate acceptance |
Summary
A mobile version is not a “squeezed desktop”. It is `tel:+998`, a working messenger, a short form, large CTAs, and a check on 4G. Ten points from your phone close half of the “the site does not sell” complaints. PageSpeed is the next layer. Hand over a site on this checklist — website development in Tashkent.
