Speed

1 to fix93
  • Render-blocking requests

    1.9 s

    9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

  • 7 third-party services on the page

    7 third-party services load with your homepage (Google Tag Manager, Google CDN and Statuspage and others), adding 353 KiB and 365 ms of main-thread time.

  • Reduce unused JavaScript

    230 ms · 125 KiB

    About 125 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 230 ms faster on a phone.

  • Use efficient cache lifetimes

    150 ms · 28 KiB

    3 files are served with short cache lifetimes, so returning visitors download them again (28 KiB).

  • 4 long tasks on the main thread

    4 long tasks block the main thread while loading, the longest for 138 ms. During a long task the page ignores taps.

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

  • Forced reflow

    Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

3 checks passed
  • Mobile performance score: 93

    93/100

    Your mobile performance score is 93. That is in Google's “good” band (90 and up).

  • Main-thread work: 0.7 s

    A phone's processor spends 0.7 s on main-thread work while loading, 338 ms of it running JavaScript. That is comfortably low.

  • Server response: 1 ms

    1 ms

    Your server sent the HTML in 1 ms, well inside Google's 600 ms guideline.

Core Web Vitals

2 to fix96
  • First Contentful Paint: 2.3 s

    2.3 s

    The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

  • Time to Interactive: 3.9 s

    3.9 s

    The page becomes fully interactive after 3.9 s. Good is under 3.8 s.

  • Not enough real-visitor data yet

    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.

4 checks passed
  • Speed Index: 3.3 s

    3.3 s

    Visually, the page fills in at 3.3 s (Speed Index), inside the 3.4 s “good” threshold.

  • Largest Contentful Paint: 2.3 s

    2.3 s

    Your largest element renders in 2.3 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “Prédiction de la demande Prédiction des ventes La maintenan…”.

  • Total Blocking Time: 121 ms

    121 ms

    Scripts block the page for only 121 ms while loading. Good is under 200 ms.

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

Images and page weight

100
  • About 0.10 g of CO₂ per visit

    0.10 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.10 g of CO₂e: 11.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed
  • Page weight: 360 KiB in 16 requests

    360 KiB

    Your homepage downloads 360 KiB in 16 requests on a phone: scripts 303 KiB (7), fonts 40 KiB (3) and stylesheets 10 KiB (3). That is a lean page.

Accessibility

6 to fixGoogle 7679
  • 5 text elements with low contrast

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

  • <html> element must have a lang attribute (1 element)

    <html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

  • All page content should be contained by landmarks (3 elements)

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

  • No main landmark

    The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

  • Page should contain a level-one heading (1 element)

    Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

  • No page language

    The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

1 checks passed
  • 13 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 18 WCAG 2.2 A/AA and best-practice rules on the phone render: 13 passed and 5 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

8 to fixGoogle 10064
  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • No structured data

    No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

  • Meta description is short (45 characters)

    Your meta description is only 45 characters: “Service de predition SAAS, modèles prédictifs”. 70 to 160 characters is enough to sell the click.

  • No canonical URL

    No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

  • No social preview image

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

  • No XML sitemap

    No XML sitemap at https://qant.io/sitemap.xml, so Google discovers your pages only by following links.

  • No robots.txt

    There is no robots.txt at qant.io/robots.txt, the first file search crawlers ask for.

  • Only 0 internal links

    The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

  • No X (Twitter) card tag

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

1 checks passed
  • Title: 36 characters

    Your title is a healthy 36 characters: “qant.io : service de prediction SAAS”.

AI search readiness

1 to fix88
  • No Organization structured data

    There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

  • No llms.txt

    There is no https://qant.io/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.

2 checks passed
  • AI answer engines may read the site

    There is no robots.txt, so nothing stops the crawlers behind ChatGPT search, Claude and Perplexity from reading the site and cite it in answers.

  • Text is in the HTML

    Your server sends the page's text in the HTML (377 words), so crawlers that don't run JavaScript still read it.

Best practices

1 to fixGoogle 10092
  • 2 JavaScript errors while loading

    2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 (Not Found)”.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

5 to fix43
  • No call to action on the first screen

    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 calls to action

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

  • No social proof

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

  • Local business without LocalBusiness data

    Your homepage shows a map but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

  • No phone number on the homepage

    A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

  • No opening hours

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

  • No form on the homepage

    There is no form on the homepage, so every lead has to click through to another page first.

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

  • About 372 words of copy

    The homepage carries about 372 words of visible text.

2 checks passed
  • Analytics in place

    Analytics detected: Google Analytics.

  • Direct contact links

    Visitors can reach you directly: 0 phone links and 1 email link.

Privacy and tracking

1 to fix
  • 3 trackers load before any consent

    3

    Before a visitor clicks anything, the page loads Google Ads, 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.

  • 2 cookies set on arrival

    2

    Opening the homepage sets 2 cookies (measured from a US location before any click).

  • No consent tool detected

    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.

  • 9 other companies contacted

    Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at qant.io, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
