previan.com website review

4 images could be 3.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 15.4 s faster on a phone.

12 files are served with short cache lifetimes, so returning visitors download them again (2.4 MB).

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

About 31 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 18 KiB of CSS is downloaded but never applied on this page.

2 third-party services load with your homepage (Cloudflare and Google Fonts), adding 87 KiB and 6 ms of main-thread time.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

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 20.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Our Foundation”.

The page becomes fully interactive after 20.4 s. Good is under 3.8 s.

Visually, the page fills in at 11.5 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 3.7 MB in 17 requests on a phone: images 3.4 MB (5), fonts 187 KiB (4) and scripts 66 KiB (5). Under 2 MB keeps phones on slow connections fast.

2 images (87 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.

1 image further down the page (28 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.04 g of CO₂e: 125.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

9 visible links have no text or label, so screen readers cannot say where they go.

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

Headings skip levels (h1 → h3 and h3 → h5), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 20 characters: “Foundation - Previan”. Between 30 and 65 characters leaves room to say what you do and for whom.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 17 pages on previan.com and 4 external pages.

https://previan.com/fr/fondation, https://previan.com/terms-of-use and https://previan.com/privacy-policy have no meta description, so Google writes the search snippet from whatever text it finds.

https://previan.com/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.

https://previan.com/our-history, https://previan.com/contact, https://previan.com/fr/fondation, https://previan.com/terms-of-use and https://previan.com/privacy-policy took over 3 s to send their HTML from our server.

We fetched 5 pages linked from your homepage and read each the way a search engine does.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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.

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 445 words of visible text.

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