Delekus: a phone-and-desktop teardown
We loaded https://delekus.com 3 times on a simulated iPhone and 2 more on a 1366px desktop, and wrote down what a real visitor would see on each, then cross-checked it against real Chrome users from Google's field data. No login, no insider access, no Harvv pixel needed. Here is what repeated visits already show, sorted by how we know it.
TL;DRWhat jumped out
Of everything we found on this scan, this is the one to start with: Tiny buttons are hard to tap on mobile. 40 of 61 tappable items on this page come in below 44×44 pixels, the minimum size Apple and Google recommend for reliable tapping, and the same ones came up small on every test load. When visitors can't hit what they expect to, they get frustrated and many of them leave instead of trying again.
Below: what's already working, every finding ranked by impact and tagged with the screen it affects, the speed numbers on phone and desktop, and a checklist of what to fix first.
00What's already working
Start here so the problems below are in context. These held up across the test loads:
- Speed is good. Real Chrome visitors see the main content in 2.3s (Google's "good" bar is 2.5s). This is field data from actual users, not a lab guess.
- Layout stays put as it loads. Real visitors see only 0.01 of layout shift (good is under 0.10), so the page is not jumping under their finger.
- Accessible to most visitors. Lighthouse accessibility is 94/100, so screen-reader and contrast basics are largely handled.
- Layout holds on phone and desktop. Nothing spilled past the edge at either 390px (phone) or 1366px (desktop), so the structure is responsive.
01Findings, ranked by what hurts conversion most
| Severity | Finding | How we know |
|---|---|---|
| High | Tiny buttons are hard to tap on mobileMobile 40 of 61 tappable items on this page come in below 44×44 pixels, the minimum size Apple and Google recommend for reliable tapping, and the same ones came up small on every test load. When visitors can't hit what they expect to, they get frustrated and many of them leave instead of trying again. | identical every load |
| High | Images without sizes set make the page jump as it loadsBoth 18 of 18 images on this page don't have width and height set. As each image finishes loading, the content below it slides down to make room. The visitor goes to tap one thing and ends up tapping another, and the cause is invisible to them. | identical every load |
| Medium | Google is writing your search snippet for youBoth This page has no meta description, so Google grabs whatever text it finds on the page and shows that under your title in search results. Usually it's not the pitch you'd write yourself. Adding a 120–160 character summary is one of the easier wins for search click-through. | identical every load |
| Medium | Page is heavy and slow on mobile dataBoth Each visit downloads about 13.5 megabytes — roughly 12149 KB of images and 1353 KB of JavaScript across 121 separate downloads. On a fast connection that's fine. On a phone with patchy mobile data, that's several seconds of blank screen before the page is readable. | median across loads |
| Medium | JavaScript crashed while the page was loadingBoth 1 script error fired during page load. When a script crashes, buttons sometimes stop working, analytics stop firing, and the visitor has no warning. Worth opening the browser console to find which script failed. | median across loads |
| Low | No canonical tag, so duplicate URLs split the page's rankingBoth When the same content is reachable at multiple URLs (think tracking parameters or session IDs), Google can split your ranking signal across them. A single canonical tag tells Google which version counts. | identical every load |
"How we know": identical every load = a deterministic fact (e.g. element sizes). median across loads = a noisy lab metric, reported as a median. real-user field data = Google CrUX, actual Chrome visitors.

Lab numbers are from a headless mobile browser on an unthrottled connection: treat them as a floor, not a typical experience.
03Tiny buttons are hard to tap on mobile
40 of 61 tappable items on this page come in below 44×44 pixels, the size Apple and Google both recommend for reliable tapping on a phone. The same ones came up small on every one of the 3 test loads, so this is the page itself, not a fluke.
The buttons measuring below the minimum on this scan:
- button 30x20 "close disclaimer"
- button 30x20 ""
- a 93x20 ""
- a 93x20 ""
- a 186x29 "placeholder home logo"
- button 26x31 "Click to open mobile menu"
- a 165x42 "FIND OUT MORE ABOUT TIMES WO"
- a 165x42 "FIND OUT MORE"
The fix is CSS-only on most sites: add padding around the icon (don't just change the icon size) so the actual tap area is at least 44×44 pixels. No redesign, no new assets.

| Title | Delek US Holdings, Inc. - Overview (34 chars) |

05The fix checklist
Everything to fix, priority first, each tagged with the screen it affects and a rough effort. Work top to bottom.
- Tiny buttons are hard to tap on mobileMobileCSS only
- Images without sizes set make the page jump as it loadsBothCSS only
- Google is writing your search snippet for youBoth1 line
- Page is heavy and slow on mobile dataBothSmall
- JavaScript crashed while the page was loadingBothDev afternoon
- No canonical tag, so duplicate URLs split the page's rankingBoth1 line
Effort is a rough read from the outside: "CSS only" means no new assets or backend work, "1 line" means a single tag, "Dev afternoon" means a developer needs to touch tracking or scripts.
06What this report cannot tell you
Everything above is from the outside, looking at the page on a simulated phone and desktop. The questions that actually decide revenue need real visitors. Install the Harvv pixel (one script tag, 16 KB, zero personal data, no engineering project) and within about 72 hours you'd know which buttons real customers tapped and missed, how often Google Analytics is missing visits, and exactly where mobile shoppers stalled and left. This report shows you where to look. The pixel shows you how often it happens, and to whom.
Drop the Harvv pixel on delekus.com and we turn this one-off scan into ongoing measured behavior: which taps miss, where sessions stall, and the real drop rates. Free to start, no card needed.
Add the pixel free07How we did this, and what it can't prove
- 3 mobile + 2 desktop loads of one URL from headless Chrome (iPhone viewport at 390px, desktop at 1366px), June 16, 2026. Enough loads to separate real defects from random noise, not a full-site crawl.
- Lab numbers, not real-user numbers, except the CrUX rows, which are real Chrome users. Real devices on real networks run slower.
- Friction is inferred, not counted. We can prove a button is small. We can't, from the outside, count how often it causes a missed tap. That requires the pixel on a live page.
