supplementhub.com website review

The page has 53,868 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 5.6 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

9 long tasks block the main thread while loading, the longest for 1.1 s. During a long task the page ignores taps.

About 1.0 MB of JavaScript is downloaded but never used on this page.

Your mobile performance score is 55. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Klaviyo, Cookiebot and Shopify and others), adding 1.7 MB and 650 ms of main-thread time.

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

33 files are served with short cache lifetimes, so returning visitors download them again (500 KiB).

Cookiebot costs a phone 136 ms of main-thread work and 499 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 138 ms of main-thread work and 350 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 112 ms of main-thread work and 309 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.

rechargecdn.com costs a phone 77 ms of main-thread work and 296 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.

136 KiB could be saved by minifying JavaScript.

2 images could be 75 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

About 15 KiB of CSS is downloaded but never applied on this page.

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.

The page becomes fully interactive after 21.1 s. Good is under 3.8 s.

Visually, the page fills in at 7.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 953 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 4.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Real visitors wait 415 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 759 ms to 713 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.7 MB in 326 requests on a phone: scripts 2.3 MB (140), other files 710 KiB (86) and images 367 KiB (51). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.04 g of CO₂e: 124.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

17 images have no alt text, which hurts accessibility and image search.

[aria-*] attributes are not valid or misspelled (1 element).

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

13 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

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

Your title is 92 characters, so Google will cut it off around 60: “Premium Supplements made available to you worldwide | Supplement Hub – Supplement Hub Glo…”.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Your <h1> is empty.

The homepage links to 229 pages on supplementhub.com and 17 external pages.

Your homepage links to https://supplementhub.com/collections/sleep-support, which answers with an error. Visitors hit a dead end and search engines drop it.

https://supplementhub.com/collections/all, https://supplementhub.com/policies/shipping-policy, https://supplementhub.com/pages/rewards, https://supplementhub.com/collections/brain-cognitive, https://supplementhub.com/collections/digestive-support and https://supplementhub.com/collections/energy-support and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://supplementhub.com/collections/all, https://supplementhub.com/policies/shipping-policy, https://supplementhub.com/pages/rewards, https://supplementhub.com/pages/help-center, https://supplementhub.com/collections/best-sellers and https://supplementhub.com/collections/winter-immunity and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 97 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Cannot read properties of null (reading 'appendChild') https://supplementhub.com/:1781:23”.

Large scripts ship without source maps.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 5 trust badges. 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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 1,100 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Hotjar, Klaviyo and Meta Pixel (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 20 cookies (measured from a US location before any click).

Loading the homepage contacts 37 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
