vibram.com website review

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.0 s faster on a phone.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

Your mobile performance score is 38 (desktop: 66). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.2 s on main-thread work while loading, 3.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,328 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

18 files are served with short cache lifetimes, so returning visitors download them again (2.3 MB).

8 third-party services load with your homepage (Google CDN, Klaviyo and Cookiebot and others), adding 1.3 MB and 1.0 s of main-thread time.

About 88 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

2 images could be 655 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google CDN costs a phone 381 ms of main-thread work and 348 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 396 ms. During a long task the page ignores taps.

Klaviyo costs a phone 286 ms of main-thread work and 338 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.

LiveChat costs a phone 94 ms of main-thread work and 364 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 29 KiB JavaScript that modern phones do not need.

Desktop scores 66 but mobile only 38. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

Your largest element takes 16.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Cliccando su “Accetta tutti i cookie”, l'utente accetta di …”.

The page becomes fully interactive after 19.6 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.8 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

1 image 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 135 ms to 145 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.5 MB in 118 requests on a phone: media 2.2 MB (2), scripts 2.1 MB (75) and images 1.0 MB (15). Under 2 MB keeps phones on slow connections fast.

3 images (446 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.57 g of CO₂e: 188.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h2 → h4 and 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.

Structured data found (Organization) but with 1 problem, for example “Organization: missing name”.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 123 pages on vibram.com and 20 external pages.

Your Organization JSON-LD is missing name, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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 77 found) and read each the way a search engine does.

18 of 46 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: net::ERR_FAILED”.

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

Large scripts ship without source maps.

1 link to other sites is dead, for example https://vibprod.returnscenter.com/ (404).

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.

vibram.com is registered until Dec 2026. Make sure auto-renew is on and the card on file is current.

vibram.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.

vibram.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 8 testimonial or review blocks. 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.

Your longest form asks for 8 fields (6 required). Every extra field lowers completion.

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

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 423 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 Tag Manager and Klaviyo (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 22 cookies, 4 of them by other companies (measured from a US location before any click).

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