fpsnavigator.com website review

About 625 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

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

5 third-party services load with your homepage (YouTube, Google Tag Manager and Other Google APIs/SDKs and others), adding 1.2 MB and 445 ms of main-thread time.

YouTube costs a phone 393 ms of main-thread work and 987 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.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

About 110 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 290 ms faster on a phone.

4 long tasks block the main thread while loading, the longest for 108 ms. During a long task the page ignores taps.

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

The first text or image appears after 6.5 s on a phone. Good is under 1.8 s.

Your largest element takes 6.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Automatisez la gestion des FPS dans votre entreprise”.

The page becomes fully interactive after 9.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.5 s (Speed Index). Good is under 3.4 s.

2 images have no width and height attributes, so the layout jumps as each one loads.

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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.36 g of CO₂e: 43.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 100 elements on the page fail this check, rated moderate by axe-core.

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

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

A phone browser shows 920 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

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.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

Chrome logged issues while loading the page (“Cookie”).

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.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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

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 920 words of visible text.

Before a visitor clicks anything, the page loads Google Ads 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 1 cookie, 1 of them by other companies (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 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
