zerosupplies.com website review

The page has 4,689 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 82. Pages that score under 90 lose visitors before the first paint.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

5 images could be 74 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.5 s on main-thread work while loading, 429 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 127 KiB of JavaScript is downloaded but never used on this page.

2 third-party services load with your homepage (Shopify and JSDelivr CDN), adding 130 KiB and 45 ms of main-thread time.

About 11 KiB of CSS is downloaded but never applied on this page.

3 files are served with short cache lifetimes, so returning visitors download them again (9 KiB).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 4.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Bolsas para envío premium recicladas y ecológicas”.

Real visitors wait 222 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

The page becomes fully interactive after 4.8 s. Good is under 3.8 s.

11 images (1.0 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.55 g of CO₂e: 66.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

4 tap targets are too small or too close together to hit reliably with a finger.

1 element hidden from screen readers can still receive keyboard focus.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

27 visible links have no text or label, so screen readers cannot say where they go.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

ARIA role should be appropriate for the element: 2 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (73 elements).

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

The homepage links to 185 pages on zerosupplies.com and 13 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User) read the homepage but closes other sections to them, so answers about those pages can't cite you.

We fetched 15 pages linked from your homepage (of 96 found) and read each the way a search engine does.

62 of 239 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Social proof on the homepage: 82 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 790 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and TikTok Pixel (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.
