bosca.com website review

About 985 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.7 s faster on a phone.

The page has 3,125 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

8 images could be 214 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

8 third-party services load with your homepage (Shopify, ZenDesk and Attentive and others), adding 1.9 MB and 613 ms of main-thread time.

About 106 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

22 files are served with short cache lifetimes, so returning visitors download them again (231 KiB).

Shopify costs a phone 292 ms of main-thread work and 1.0 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.

A phone's processor spends 3.5 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

ZenDesk costs a phone 149 ms of main-thread work and 386 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.

Attentive costs a phone 81 ms of main-thread work and 308 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.

7 long tasks block the main thread while loading, the longest for 154 ms. During a long task the page ignores taps.

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

Polyfills for old browsers add 35 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 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.

4 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.

Your largest element takes 14.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “a group of wallets on a green background”.

The page becomes fully interactive after 18.0 s. Good is under 3.8 s.

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

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

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 121 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.8 MB in 295 requests on a phone: scripts 1.7 MB (83), other files 881 KiB (148) and images 739 KiB (34). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.07 g of CO₂e: 128.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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.

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

The homepage links to 408 pages on bosca.com and 11 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.

We fetched 15 pages linked from your homepage (of 93 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=151011383&tm=gtm002&Ver=2&mid=cb4fba50-9588-43dd-969f-b69d2b61640c&bo=1&sid=e56d61e0d8de11f1aab1bfff77314060&vid=e56d97b0d8de11f1aad0c1d0302b74bd&vids=1&msclkid=N&pi=9.

61 of 99 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 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 ()”.

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.

bosca.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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

The homepage has only about 243 words of visible text; thin pages give Google and first-time buyers little to go on.

DMARC is set to p=none, so mail pretending to be bosca.com is still delivered. Reports are on, so moving to quarantine is the next step.

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, Hotjar and Klaviyo 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 32 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.
