40bis.com website review

About 198 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.

Your mobile performance score is 40. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

42 files are served with short cache lifetimes, so returning visitors download them again (11.2 MB).

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

Google Tag Manager costs a phone 155 ms of main-thread work and 298 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 images could be 116 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.

5 third-party services load with your homepage (Google Tag Manager, Clarity and axept.io and others), adding 378 KiB and 211 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 102 ms. During a long task the page ignores taps.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

The layout shifts by 0.915 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Your largest element takes 7.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The first text or image appears after 4.7 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 7.1 s. Good is under 3.8 s.

Visually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 11.5 MB in 54 requests on a phone: images 11.1 MB (39), scripts 414 KiB (6) and fonts 49 KiB (1). Under 2 MB keeps phones on slow connections fast.

12 images weigh 9.4 MB together. On a phone connection a single image that size takes seconds.

SHOWROOM_40BIS_20-01-2024_0011FINAL-2400x1600.webp 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 3.27 g of CO₂e: 392.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

<html> element must have a valid value for the lang attribute: 1 element on the page fails this check, rated serious by axe-core.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious 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.

The page declares lang=“en_GB”, which is not a usable language code, so screen readers and translation tools guess.

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

The homepage links to only 4 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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.

/about and /contact have no meta description, so Google writes the search snippet from whatever text it finds.

/contact has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 2 pages linked from your homepage and read each the way a search engine does.

6 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

HSTS is set, but max-age is 185 days; one year is the recommended minimum.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

40bis.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.

40bis.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 20 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

40bis.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

40bis.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 Analytics, Google Tag Manager 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 8 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.
