protein.com website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

A phone's processor spends 6.8 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.

About 311 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 51 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

The page has 2,743 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Shopify costs a phone 31 ms of main-thread work and 351 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.

8 third-party services load with your homepage (loox.io, Klaviyo and richpanel.com and others), adding 721 KiB and 395 ms of main-thread time.

11 long tasks block the main thread while loading, the longest for 212 ms. During a long task the page ignores taps.

7 images could be 85 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

11 files are served with short cache lifetimes, so returning visitors download them again (30 KiB).

Polyfills for old browsers add 29 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.

3 KiB JavaScript is shipped twice across bundles.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 26.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 26.6 s. Good is under 3.8 s.

For real visitors the layout shifts by 0.11 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 129 ms to 164 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 402 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 3.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.3 MB in 169 requests on a phone: fonts 4.0 MB (9), scripts 832 KiB (70) and images 701 KiB (29). Under 2 MB keeps phones on slow connections fast.

mobile_banners_January_2026_23.jpg 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 1.79 g of CO₂e: 214.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

Heading levels should only increase by one: 2 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.

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

ARIA role should be appropriate for the element: 14 elements on the page fail this check, rated minor by axe-core.

Your meta description is only 13 characters: “Empower Women”. 70 to 160 characters is enough to sell the click.

There are 2 <h1> headlines (“” and “Just started your GLP-1 Journey?”). One clear main headline is easier for people and search engines.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 88 pages on protein.com and 4 external pages.

We fetched 15 pages linked from your homepage (of 28 found) and read each the way a search engine does.

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

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.

protein.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.

protein.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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

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

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

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 798 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

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 Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (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 26 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 37 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
