stoxenergy.com website review

A phone's processor spends 5.7 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Clarity and Facebook and others), adding 8.9 MB and 1.3 s of main-thread time.

Your mobile performance score is 77. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 14 ms of main-thread work and 7.5 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.

Google Tag Manager costs a phone 473 ms of main-thread work and 674 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 468 KiB of JavaScript is downloaded but never used on this page.

11 images could be 304 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

10 long tasks block the main thread while loading, the longest for 337 ms. During a long task the page ignores taps.

Clarity costs a phone 307 ms of main-thread work and 28 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.

10 files are served with short cache lifetimes, so returning visitors download them again (307 KiB).

The page has 2,126 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Klaviyo costs a phone 152 ms of main-thread work and 333 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.

Polyfills for old browsers add 42 KiB JavaScript that modern phones do not need.

About 19 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 10 ms faster on a phone.

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.

5 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 17.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 617 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 132 ms to 171 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.1 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 14.9 MB in 337 requests on a phone: media 10.4 MB (2), images 1.7 MB (55) and scripts 1.6 MB (77). Under 2 MB keeps phones on slow connections fast.

FW26_Merino_Everyday_Sept_Homepage_Hero_Mobile_Still.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 4.24 g of CO₂e: 508.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

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

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

All page content should be contained by landmarks: 14 elements on the page fail 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.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Alternative text of images should not be repeated as text: 9 elements on the page fail this check, rated minor by axe-core.

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 167 pages on stoxenergy.com and 11 external pages.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/pages/help and /customer_authentication/redirect have no meta description, so Google writes the search snippet from whatever text it finds.

/customer_authentication/redirect and /pages/technology have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 89 found) and read each the way a search engine does.

28 of 116 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://stoxenergy.com/customer_authentication/redirect?locale=en&region_country=NL&account_url=https%3A%2F%2Faccount.stoxenergy.com%2Fprofile.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

stoxenergy.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

stoxenergy.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

The homepage carries about 933 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Microsoft Clarity (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 12 cookies (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 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
