greenkeratinlabs.com website review

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

About 119 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

8 third-party services load with your homepage (Shopify, loox.io and Google Tag Manager and others), adding 1.6 MB and 360 ms of main-thread time.

Shopify costs a phone 123 ms of main-thread work and 1.3 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 2.6 s on main-thread work while loading, 816 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,304 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

2 long tasks block the main thread while loading, the longest for 100 ms. During a long task the page ignores taps.

9 files are served with short cache lifetimes, so returning visitors download them again (65 KiB).

About 22 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 20 ms faster on a phone.

1 image could be 23 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 7.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Video Cover”.

Visually, the page fills in at 7.7 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 7.7 s. Good is under 3.8 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 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 53.7 MB in 303 requests on a phone: media 50.6 MB (5), images 1.3 MB (28) and other files 873 KiB (131). Under 2 MB keeps phones on slow connections fast.

2 images further down the page (41 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 15.23 g of CO₂e: 1827.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 buttons have no accessible name, so screen readers announce just “button”.

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

6 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate 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.

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

Headings skip levels (h2 → h4, h2 → h4 and h2 → h5), 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.

Your canonical URL points to greenkeratin.eu, not greenkeratinlabs.com, so Google may credit that host instead.

The homepage links to 149 pages on greenkeratinlabs.com and 5 external pages.

/collections/best-sellers, /collections/nouveautes, /collections/routines, /collections/all, /collections/masques-nettoyants and /collections/essences and 9 others use the same meta description. A description written for each page earns more clicks.

/collections/best-sellers, /collections/nouveautes, /collections/routines, /collections/all, /collections/masques-nettoyants and /collections/essences 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 72 found) and read each the way a search engine does.

58 of 103 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://greenkeratin.eu/customer_authentication/redirect?locale=fr&region_country=FR.

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.

greenkeratinlabs.com is registered until Dec 2026. If it lapses, the site and its email stop working and someone else can buy the name. Renew it, and turn on auto-renew.

greenkeratinlabs.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.

greenkeratinlabs.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.

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

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 762 words of visible text.

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

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 and Google Tag Manager (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 6 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 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
