upstartepoxy.com website review

A phone's processor spends 5.1 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

23 files are served with short cache lifetimes, so returning visitors download them again (3.1 MB).

About 687 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 840 ms faster on a phone.

8 third-party services load with your homepage (rebuyengine.com, Shopify and Klaviyo and others), adding 5.3 MB and 890 ms of main-thread time.

Your mobile performance score is 54. Pages that score under 90 lose visitors before the first paint.

About 507 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 330 ms faster on a phone.

5 images could be 142 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

fokkio.com costs a phone 79 ms of main-thread work and 3.0 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

rebuyengine.com costs a phone 224 ms of main-thread work and 684 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Shopify costs a phone 180 ms of main-thread work and 861 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Klaviyo costs a phone 172 ms of main-thread work and 312 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

43 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 93 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

13 long tasks block the main thread while loading, the longest for 192 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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.

Your largest element takes 11.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 27.4 s. Good is under 3.8 s.

Visually, the page fills in at 8.8 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 442 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

6 images have no width and height attributes, so the layout jumps as each one loads.

Your homepage downloads 6.7 MB in 392 requests on a phone: images 2.6 MB (18), scripts 2.3 MB (238) and other files 783 KiB (100). Under 2 MB keeps phones on slow connections fast.

1 image (81 KiB) is 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 1.90 g of CO₂e: 228.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

The homepage links to 112 pages on upstartepoxy.com and 10 external pages.

https://www.upstartepoxy.com/collections/all, https://www.upstartepoxy.com/collections/bundles, https://www.upstartepoxy.com/collections/frontpage, https://www.upstartepoxy.com/collections/mica-powders-dyes, https://www.upstartepoxy.com/blogs/news and https://www.upstartepoxy.com/pages/faq and 1 other have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 50 found) and read each the way a search engine does.

3 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 28 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.

The homepage shows no opening hours. If customers visit or call, show when.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 633 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (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.

Opening the homepage sets 18 cookies, 1 of them by other companies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 44 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
