boxcomponents.com website review

About 689 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

A phone's processor spends 7.7 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,976 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Klaviyo, Shopify and Affirm and others), adding 2.5 MB and 921 ms of main-thread time.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

About 109 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Klaviyo costs a phone 281 ms of main-thread work and 525 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 177 ms of main-thread work and 970 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.

tidio.co costs a phone 104 ms of main-thread work and 515 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.

18 files are served with short cache lifetimes, so returning visitors download them again (244 KiB).

3 images could be 68 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.

17 long tasks block the main thread while loading, the longest for 180 ms. During a long task the page ignores taps.

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

Polyfills for old browsers add 25 KiB JavaScript that modern phones do not need.

14 KiB could be saved by minifying CSS.

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.

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 28.1 s. Good is under 3.8 s.

Your largest element takes 7.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Slideshow Image 1”.

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 161 ms to 218 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 382 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.4 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 6.3 MB in 597 requests on a phone: images 2.5 MB (272), scripts 2.2 MB (148) and other files 962 KiB (143). Under 2 MB keeps phones on slow connections fast.

Feature-CamWood-HB-Mobile-d01_1.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).

2 images further down the page (43 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.78 g of CO₂e: 214.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

6 elements hidden from screen readers can still receive keyboard focus.

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

ARIA commands must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

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: 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.

Elements with visible text labels do not have matching accessible names. (2 elements).

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

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 122 pages on boxcomponents.com and 9 external pages.

/collections/bottom-brackets, /collections/cranksets, /collections/drivetrain, /collections/forks, /collections/headsets and /collections/number-plates and 6 others have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/bottom-brackets, /collections/braking, /collections/cranksets, /collections/drivetrain, /collections/forks and /collections/handlebars and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 59 found) and read each the way a search engine does.

8 of 33 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 (“Authorization will not be covered by the wildcard symbol (*) in CORS `Access-Control-Allow-Headers`…”).

2 errors were logged to the browser console while the page loaded, for example “Uncaught Error: Goaffpro is already loaded. This message prevents duplicate loading of the script. Kindly ignore.”.

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

HSTS is set, but max-age is 91 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.

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.

boxcomponents.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.

boxcomponents.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.

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.

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 701 words of visible text.

DMARC is set to p=none, so mail pretending to be boxcomponents.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 Meta 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 23 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 48 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
