sfox.com website review

About 938 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.9 s faster on a phone.

19 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

Your mobile performance score is 45. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 7.0 s on main-thread work while loading, 3.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,419 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Cloudflare CDN, YouTube and Google Tag Manager and others), adding 4.3 MB and 2.1 s of main-thread time.

About 163 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 690 ms faster on a phone.

2 images could be 193 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 650 ms faster on a phone.

YouTube costs a phone 560 ms of main-thread work and 963 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.

Cloudflare CDN costs a phone 570 ms of main-thread work and 63 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 Tag Manager costs a phone 441 ms of main-thread work and 326 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.

20 long tasks block the main thread while loading, the longest for 415 ms. During a long task the page ignores taps.

Vimeo costs a phone 56 ms of main-thread work and 2.7 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.

JSDelivr CDN costs a phone 274 ms of main-thread work and 96 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.

11 files are served with short cache lifetimes, so returning visitors download them again (92 KiB).

3 KiB could be saved by minifying CSS.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

29 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 28 KiB JavaScript that modern phones do not need.

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.

Real visitors see the first content after 3.1 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 26.9 s on a phone. Good is under 1.8 s.

Your largest element takes 41.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Since 2014, sFOX has unified trading, custody, liquidity, a…”.

Visually, the page fills in at 26.9 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 47.0 s. Good is under 3.8 s.

Real visitors wait 3.3 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.2 s to 3.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Scripts block taps and scrolling for 412 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 11.1 MB in 139 requests on a phone: fonts 4.1 MB (4), other files 2.6 MB (37) and images 2.2 MB (40). Under 2 MB keeps phones on slow connections fast.

2 images weigh 1.4 MB together. On a phone connection a single image that size takes seconds.

5 images (2.0 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.

1 image further down the page (105 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 3.16 g of CO₂e: 379.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 frame has no title, so screen-reader users cannot tell what it contains.

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

Your meta description is 179 characters; Google truncates after about 160, so the end of your pitch is cut.

4 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 59 pages on sfox.com and 13 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

7 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

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

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

4 errors were logged to the browser console while the page loaded, for example “Cannot set properties of null (setting 'href')”.

Chrome logged issues while loading the page (“Cookie”).

HSTS is set, but max-age is 30 days; one year is the recommended minimum.

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.

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

sfox.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.

Social proof on the homepage: 1 customer or partner logo. Pairing it with named testimonials or customer logos makes it far more convincing.

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

There is no form on the homepage, so every lead has to click through to another page first.

The homepage carries about 803 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, Segment and X (Twitter) Ads (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, 2 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 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
