greenwhey.com website review

About 285 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

A phone's processor spends 5.1 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Shopify, Klaviyo and Google Tag Manager and others), adding 2.2 MB and 818 ms of main-thread time.

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 526 ms of main-thread work and 1.5 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.

Klaviyo costs a phone 153 ms of main-thread work and 313 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.

4 images could be 178 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 long tasks block the main thread while loading, the longest for 150 ms. During a long task the page ignores taps.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

5 files are served with short cache lifetimes, so returning visitors download them again (32 KiB).

Polyfills for old browsers add 30 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.

The page becomes fully interactive after 17.3 s. Good is under 3.8 s.

Your largest element takes 6.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 7.4 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 248 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 2.4 MB in 140 requests on a phone: images 1,022 KiB (23), scripts 976 KiB (80) and fonts 303 KiB (8). Under 2 MB keeps phones on slow connections fast.

banniere_petite-CollageneMatcha.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).

2 images (147 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 0.68 g of CO₂e: 82.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

The homepage links to 113 pages on greenwhey.com and 3 external pages.

/collections/tous-les-packs has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 53 found) and read each the way a search engine does.

29 of 56 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“CSS appearance value `slider-vertical` is not standardized and will be removed.”).

Chrome logged issues while loading the page (“Content security policy”).

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.

greenwhey.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.

greenwhey.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.

Social proof on the homepage: “400K clients”. Pairing it with named testimonials or customer logos makes it far more convincing.

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 533 words of visible text.

DMARC is set to p=none, so mail pretending to be greenwhey.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 Tag Manager, Pinterest Tag and Snap Pixel (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 11 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.
