scivation.com website review

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

About 921 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

8 third-party services load with your homepage (Shopify, Google Tag Manager and iovation and others), adding 1.7 MB and 1.0 s of main-thread time.

Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.

40 files are served with short cache lifetimes, so returning visitors download them again (685 KiB).

A phone's processor spends 4.0 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

4 images could be 292 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google Tag Manager costs a phone 185 ms of main-thread work and 337 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.

narvar.com costs a phone 117 ms of main-thread work and 465 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.

Google CDN costs a phone 111 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.

About 88 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

38 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 150 ms faster on a phone.

15 long tasks block the main thread while loading, the longest for 182 ms. During a long task the page ignores taps.

Polyfills for old browsers add 61 KiB JavaScript that modern phones do not need.

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

9 KiB could be saved by minifying JavaScript.

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

3 KiB could be saved by minifying CSS.

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 27.8 s. Good is under 3.8 s.

Your largest element takes 7.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Recovery that goes further than hydration* | Incredible Fla…”.

Scripts block taps and scrolling for 643 ms in total while the page loads. Good is under 200 ms.

For real visitors the layout shifts by 0.12 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 111 ms to 143 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

12 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' largest content (lcp) went from 1.9 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.5 MB in 375 requests on a phone: scripts 2.4 MB (121), other files 939 KiB (170) and images 590 KiB (23). Under 2 MB keeps phones on slow connections fast.

5 images are downloaded at several times the size a phone draws them, for example Cobrand_0462_Digital_AugustDTC_XTEND_BackToSport_WebBanner_M at 1,667 px wide, shown at 390 px. Resized copies would save about 338 KiB.

4 images (481 KiB) 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 1.27 g of CO₂e: 152.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 frames have no title, so screen-reader users cannot tell what they contain.

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

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is 76 characters, so Google will cut it off around 60: “XTEND | The Official Hydration + BCAA Recovery Brand of Champions – Cellucor”.

The homepage links to 83 pages on scivation.com and 9 external pages.

https://cellucor.com/pages/performance-energy-bundle, https://cellucor.com/pages/c4-supps, https://cellucor.com/collections/hydration and https://cellucor.com/collections/xtend-hydration-recovery have no meta description, so Google writes the search snippet from whatever text it finds.

/, https://cellucor.com/pages/performance-energy-bundle, https://cellucor.com/pages/c4-energy, https://cellucor.com/pages/c4-supps and https://cellucor.com/pages/cellucor-subscribe-save have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 34 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://segment.prod.bidr.io/associate-segment?buzz_key=tatari&segment_key=tatari-4492&value=&uncacheplz=7697891312.

10 of 26 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 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 ()”.

1 image is served at too low a resolution for sharp phone screens.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 482 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and LinkedIn Insight and 4 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 46 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 82 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
