What your site is actually doing.

One page: what is working, what is costing you visitors, and what to fix next. A phone-and-desktop teardown of the live site: 4 phone loads + 2 desktop loads, cross-checked against real Chrome users from Google's field data. No login, no insider access, no Harvv pixel needed. The full evidence is at the bottom.

This is one of several oil refiner sites we tore down the same way. The same friction repeats on Par Pacific, and we pulled the cross-site pattern together in the oil-refiner web benchmark.

01Findings, ranked by what hurts conversion most

SeverityFindingHow we know
HighA floating widget is covering a clickable elementBothConversionAccessibility (WCAG)
12 clickable elements are sitting underneath a fixed overlay (div#cm_disclaimer-header over button "Previous slide"), so a visitor who tries to tap them hits the widget on top instead. The element is there and looks fine in a preview, it just can't be reached. Move the floating widget to a clear corner, lower its z-index, or add spacing so it never overlaps your links and buttons.

HighPage contains "Lorem ipsum" placeholder textBothConversionSEO
Real visitors see this rendered text. It almost always means a template variable, localization string, or third-party widget failed to render. Search the page for the exact pattern and fix the source.

MediumTiny buttons are hard to tap on mobileMobileAccessibility (WCAG)Conversion
20 of 61 tappable items on this page (33%) measure under 24 pixels on their shorter side, below the WCAG minimum, and well under the 44 pixels 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.
paste into Claude, Cursor, or ChatGPT
MediumGoogle is writing your search snippet for youBothSEO
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 to 160 character summary is one of the easier wins for search click-through.
paste into Claude, Cursor, or ChatGPT
MediumPage is heavy and slow on mobile dataBothPerformance
Each visit downloads about 13.5 megabytes, roughly 12150 KB of images and 1353 KB of JavaScript across 115 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.

LowImages have no width or height set (layout is stable for now)BothPerformanceSEO
18 of 18 images don't declare width and height. Your layout currently stays stable (measured Cumulative Layout Shift is 0.01, which is fine), most likely because space is reserved another way (CSS), so this is not causing visible jumps today. It is still worth setting explicit dimensions or a CSS aspect-ratio so a slow connection or a future style change cannot reintroduce shift.

LowNo 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.
paste into Claude, Cursor, or ChatGPT
LowSecurity headers are missing or weakBothSecurity
The server response is missing browser-hardening headers that protect visitors and are a standard security and agency checklist item. Missing or weak here: Content-Security-Policy (the main defense against injected and cross-site scripts). These are set at the server, CDN, or host level (most platforms expose them in settings or a config file) and do not change how the site looks or performs.
paste into Claude, Cursor, or ChatGPT
LowLinks to this page will look bare when sharedBoth
The page is missing its Open Graph title and image, so when someone shares it on Facebook, LinkedIn, iMessage, or Slack the preview has no title and image. A flat grey link gets far fewer clicks than one with an image and headline.
paste into Claude, Cursor, or ChatGPT
LowNo structured data for rich search resultsBoth
The page has no schema.org markup. Adding the right type (Product, Article, Organization, FAQ) lets Google show rich results like star ratings and prices, which lift click-through for free.

LowThe page loads from a lot of third-party servicesBoth
Around 18 separate outside domains load on this page (analytics, ads, chat widgets, fonts). Each one is a connection that can be slow, fail, or change behavior outside your control.

LowNo third-party analytics tag detectedBothTracking
No Google Analytics, GA4, or other third-party analytics tag was found in the page. If you rely only on platform or server-side analytics that is fine; but if not, a third-party tag is the baseline way to see how many visitors arrive, where they come from, and what converts. First-party or server-side analytics are not detectable from the outside, so this may already be handled.

LowNo email capture or newsletter detectedBothConversion
No email-marketing tag (Klaviyo, Mailchimp, etc.) was found. If capturing visitors is relevant to this site, an email signup builds an owned audience you keep regardless of ad costs. Not every site needs one.

LowNo visible contact details (email or phone)BothConversion
The page exposes no email or phone link. For higher-value or trust-sensitive purchases, a clear way to reach a human reduces hesitation. Add an email or phone link in the header or footer.

Accessibility findings are automated checks against Web Content Accessibility Guidelines (WCAG) 2.1 and 2.2. They flag potential barriers and legal risk, not a certification or a determination of compliance with the ADA, Section 508, or EN 301 549. Automated testing catches only a subset of issues; a full conformance review needs manual and assistive-technology testing by a qualified reviewer.

"How we know": unlabeled = a deterministic fact, identical on every load (e.g. element sizes). Most findings are this kind, so we only mark the exceptions: median across loads = a noisy lab metric, reported as a median. real-user field data = Google CrUX, actual Chrome visitors.

Every finding above in one payload, with the reasoning behind each one. The prompt is written to be pasted into Claude, Cursor, or ChatGPT. The JSON is for piping into your own tooling.

Includes the site context, what is already working (so your assistant does not "fix" it), and every finding with its severity, evidence, and why it matters.
Audit of https://delekus.com, run August 16, 2026. 20 issues were found. I want them fixed.

## Context
- Site: https://delekus.com
- Mobile LCP (lab median): 410 ms
- Desktop LCP (lab median): 434 ms
- Page weight (median): 13.5 MB
- Tap targets under 44px: 33% (20 of 61)
- Evidence base: 4 mobile + 2 desktop loads + Google CrUX field data

## Already working, do not change these
- Speed is good: Real Chrome visitors see the main content in 2.1s (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.
- Layout holds on phone and desktop: Nothing spilled past the edge at either 390px (phone) or 1366px (desktop), so the structure is responsive.

## Issues, most damaging first

### 1. [HIGH] A floating widget is covering a clickable element
Category: Conversion, Accessibility (WCAG)
Why it matters: 12 clickable elements are sitting underneath a fixed overlay (div#cm_disclaimer-header over button "Previous slide"), so a visitor who tries to tap them hits the widget on top instead. The element is there and looks fine in a preview, it just can't be reached. Move the floating widget to a clear corner, lower its z-index, or add spacing so it never overlaps your links and buttons.
Exact elements found: button "Previous slide" under div#cm_disclaimer-header, button "Next slide" under div#cm_disclaimer-header, a "SIGN UP FOR EMAIL ALERTS 
(O" under div#cm_disclaimer-header, a "About Us" under p, a "Business Operations" under p, a "Investors" under p

### 2. [HIGH] Page contains "Lorem ipsum" placeholder text

## How to respond
Work through the issues in order. For each one give me the specific change that fixes it: real code or real copy, not advice. Keep changes minimal and match the existing style of the site.
Where several issues share one root cause, say so and fix it once rather than patching each symptom.
If an issue cannot be fixed without seeing more of the code, say exactly which file or selector you need instead of guessing.

03Tiny buttons are hard to tap on mobile

20 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 4 test loads, so this is the page itself, not a fluke.

When customers can't tap what they expect to, they get frustrated and many of them leave. They don't file a bug. They don't try again. They just leave. A desktop dashboard can't see this because it's the difference between a thumb and a cursor.

The buttons measuring below the minimum on this scan:

  • button 30x20 "close disclaimer"
  • button 30x20 (no visible label)
  • a 93x20 (no visible label)
  • a 93x20 (no visible label)
  • button 8x8 "Go to slide 1"
  • button 8x8 "Go to slide 2"
  • button 8x8 "Go to slide 3"
  • a 88x18 "READ MORE REFINING"

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.

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.

What to do next
See this same depth on your real visitors, every day.

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 free

07How we did this, and what it can't prove

  • 4 mobile + 2 desktop loads of one URL from headless Chrome (iPhone viewport at 390px, desktop at 1366px), August 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.

About Harvv, the source of this teardown

Harvv is a behavioral UX analytics platform (harvv.com). A lightweight JavaScript pixel captures how real visitors behave on a site (dead clicks, rage clicks, scroll depth, Core Web Vitals, JavaScript errors, and 50+ other signals) and the engine turns them into prioritized, plain-English findings. This teardown is the outside-in version of that: the same detectors run against a public page, with no pixel installed.

How to read it. Every finding here is a reproducible, automated measurement, not an opinion: element sizes, contrast ratios, load metrics, and structured-data checks that anyone can re-run against the same URL. The method is stated in full above. Automated testing catches a subset of issues, so this is a starting point, not a certification.

Full disclosure. Harvv makes the pixel that would measure the friction these findings imply, so we have a commercial interest. That is exactly why the findings are kept to things a reader can verify independently, and why nothing here is inflated: an unreproducible claim would undermine the tool it is meant to demonstrate.
