size-factory.com website review

About 189 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 74 (desktop: 97). Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 900 ms.

15 files are served with short cache lifetimes, so returning visitors download them again (415 KiB).

About 488 KiB of JavaScript is downloaded but never used on this page.

14 images could be 317 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 349 ms. During a long task the page ignores taps.

A phone's processor spends 3.2 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (wonderpush.com, Clarity and Doofinder and others), adding 371 KiB and 384 ms of main-thread time.

Polyfills for old browsers add 18 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.

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.

The page becomes fully interactive after 11.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 652 ms in total while the page loads. Good is under 200 ms.

For real visitors the layout shifts by 0.21 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 0.9 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.2 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 4.2 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 2026-10-17, real Chrome visitors' tap response (inp) went from 111 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.3 MB in 72 requests on a phone: scripts 1,000 KiB (21), images 995 KiB (26) and stylesheets 209 KiB (3). Under 2 MB keeps phones on slow connections fast.

1 image (85 KiB) is 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 0.65 g of CO₂e: 78.0 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”.

3 elements hidden from screen readers can still receive keyboard focus.

Elements must only use permitted ARIA attributes: 3 elements on the page fail this check, rated serious by axe-core.

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

ARIA toggle fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Some lists contain elements other than list items, which screen readers announce wrongly.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

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

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

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

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

3 links have no real href, so search engines can't follow them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 176 pages on size-factory.com and 4 external pages.

Your Organization JSON-LD is missing 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.

/12095-promo-pantalons has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 145 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.net/action/0?ti=5216104&tm=gtm002&Ver=2&mid=54fc62c2-11ac-4fde-9881-9685528f8220&bo=2&pi=918639831&lg=en-US&sw=390&sh=844&sc=24&nwd=1&tl=Size%20Factory%20%3A%20V%C3%AAtements%20Homme%.

3 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://cdn.doofinder.com/livelayer/1.8.209/css/2/common.css?v=1.8.209' from origin 'https…”.

Large scripts ship without source maps.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

size-factory.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.

size-factory.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 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 432 words of visible text.

DMARC is set to p=none, so mail pretending to be size-factory.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, Microsoft Ads and Microsoft Clarity (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 10 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 24 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
