supdepub.com website review

Google Tag Manager costs a phone 1.4 s of main-thread work and 820 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

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

A phone's processor spends 4.4 s on main-thread work while loading, 2.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Clarity and greenbureau.com and others), adding 1.9 MB and 1.9 s of main-thread time.

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

About 908 KiB of JavaScript is downloaded but never used on this page.

6 files are served with short cache lifetimes, so returning visitors download them again (422 KiB).

15 long tasks block the main thread while loading, the longest for 375 ms. During a long task the page ignores taps.

greenbureau.com costs a phone 150 ms of main-thread work and 696 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.

The page has 1,774 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

1 image could be 101 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 93 KiB of CSS is downloaded but never applied on this page.

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 18.8 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.5 s in total while the page loads. Good is under 200 ms.

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 183 ms to 203 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.1 MB in 95 requests on a phone: images 3.8 MB (19), scripts 2.0 MB (42) and stylesheets 117 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.74 g of CO₂e: 208.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 6 elements on the page fail this check, rated critical by axe-core.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

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

Some list items are not inside a list.

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

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

Your meta description is 176 characters; Google truncates after about 160, so the end of your pitch is cut.

13 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 158 pages on supdepub.com and 35 external pages.

There is no https://www.supdepub.com/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.

https://www.supdepub.com/en, https://www.supdepub.com/en/studying-with-a-disability and / all use the title “Sup de Pub - School of Communication”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.supdepub.com/en/immersive-pedagogy, https://www.supdepub.com/en/the-professors, https://www.supdepub.com/en/educational-tools, https://www.supdepub.com/en/the-creative-awards, https://www.supdepub.com/en/branded-guests-and-partnerships and https://www.supdepub.com/en/campus/international-campuses have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.supdepub.com/en/studying-with-a-disability and / use the same meta description. A description written for each page earns more clicks.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example https://www.supdepub.com/en/studying-with-a-disability, whose canonical is https://www.supdepub.com/en. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 105 found) and read each the way a search engine does.

5 images failed to load on a phone, for example https://www.supdepub.com/en/.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

4 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 ()”.

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.

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 1,291 words of visible text.

Before a visitor clicks anything, the page loads Criteo, Google Ads, Google Tag Manager, HubSpot and Microsoft Clarity (measured from a US location before any click). A consent tool (Didomi) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 4 cookies (measured from a US location before any click).

Loading the homepage contacts 20 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
