bitfinex.com website review

99 files are served with short cache lifetimes, so returning visitors download them again (5.4 MB).

A phone's processor spends 10.7 s on main-thread work while loading, 5.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 36. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

6 images could be 2.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 third-party services load with your homepage (Google Tag Manager, ZenDesk and Facebook and others), adding 1.3 MB and 2.2 s of main-thread time.

About 985 KiB of JavaScript is downloaded but never used on this page.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

Google Tag Manager costs a phone 768 ms of main-thread work and 349 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 663 ms. During a long task the page ignores taps.

ZenDesk costs a phone 587 ms of main-thread work and 451 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.

Facebook costs a phone 500 ms of main-thread work and 212 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 51 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).

About 19 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.

3 KiB could be saved by minifying JavaScript.

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 31.2 s. Good is under 3.8 s.

Your largest element takes 7.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Scripts block taps and scrolling for 2.5 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 9.5 s (Speed Index). Good is under 3.4 s.

Real visitors wait 268 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 270 ms to 272 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 17.3 MB in 177 requests on a phone: media 8.6 MB (3), images 4.8 MB (35) and scripts 3.0 MB (70). Under 2 MB keeps phones on slow connections fast.

mobile_device.svg weighs 700 KiB. On a phone connection a single image that size takes seconds.

1 image further down the page (700 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

1 image (53 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 4.90 g of CO₂e: 588.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

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

1 link inside paragraphs relies on colour alone to stand out.

1 tap target is too small or too close together to hit reliably with a finger.

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

All page content should be contained by landmarks: 33 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

6 form fields have no label, so screen readers announce an empty box and autofill guesses.

1 visible link has no text or label, so screen readers cannot say where it goes.

ARIA role should be appropriate for the element: 9 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h4), which makes the page harder to scan with a screen reader.

<td> elements in a large <table> do not have table headers. (1 element).

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

There are 4 <h1> headlines (“The OriginalBitcoin Exchange”, “Stay Ahead with Real-Time Market Data” and “Battle tested since 2012”). One clear main headline is easier for people and search engines.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Your meta description is 167 characters; Google truncates after about 160, so the end of your pitch is cut.

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

2 links have no real href, so search engines can't follow them.

The homepage links to 51 pages on bitfinex.com and 39 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 33 found) and read each the way a search engine does.

10 of 23 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.”).

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Chrome logged issues while loading the page (“Content security policy”).

Large scripts ship without source maps.

2 links go through two or more redirects, for example https://support.bitfinex.com/.

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.

bitfinex.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.

bitfinex.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.

Social proof on the homepage: 6 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 form on the homepage, so every lead has to click through to another page first.

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 300 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 Amplitude, Google Analytics, Google Tag Manager, Meta Pixel and Reddit Pixel and 1 more (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 3 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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
