Speed

5 to fix59
  • Improve image delivery

    5.7 s · 1.5 MB

    9 images could be 1.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 5.7 s faster on a phone.

  • Reduce unused JavaScript

    1.2 s · 249 KiB

    About 249 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

  • Mobile performance score: 59

    59/100

    Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

  • Render-blocking requests

    450 ms

    6 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

  • Google Tag Manager adds 224 ms

    224 ms

    Google Tag Manager costs a phone 224 ms of main-thread work and 465 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.

  • 5 third-party services on the page

    5 third-party services load with your homepage (Google Tag Manager, Cloudflare CDN and Shopify and others), adding 617 KiB and 330 ms of main-thread time.

  • Use efficient cache lifetimes

    150 ms · 21 KiB

    4 files are served with short cache lifetimes, so returning visitors download them again (21 KiB).

  • 2 long tasks on the main thread

    2 long tasks block the main thread while loading, the longest for 118 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.

2 checks passed
  • Main-thread work: 1.2 s

    A phone's processor spends 1.2 s on main-thread work while loading, 506 ms of it running JavaScript. That is comfortably low.

  • Server response: 5 ms

    5 ms

    Your server sent the HTML in 5 ms, well inside Google's 600 ms guideline.

Core Web Vitals

4 to fix62
  • Largest Contentful Paint: 18.9 s

    18.9 s

    Your largest element takes 18.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • Time to Interactive: 19.1 s

    19.1 s

    The page becomes fully interactive after 19.1 s. Good is under 3.8 s.

  • Speed Index: 10.6 s

    10.6 s

    Visually, the page fills in at 10.6 s (Speed Index). Good is under 3.4 s.

  • First Contentful Paint: 2.4 s

    2.4 s

    The first text or image appears after 2.4 s on a phone. Good is under 1.8 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.

2 checks passed
  • Cumulative Layout Shift: 0.097

    0.097

    The layout barely moves while loading (CLS 0.097, good is under 0.1).

  • Total Blocking Time: 114 ms

    114 ms

    Scripts block the page for only 114 ms while loading. Good is under 200 ms.

Images and page weight

3 to fix45
  • Page weight: 4.2 MB in 183 requests

    4.2 MB

    Your homepage downloads 4.2 MB in 183 requests on a phone: images 2.5 MB (15), other files 777 KiB (95) and scripts 716 KiB (41). Under 2 MB keeps phones on slow connections fast.

  • 2 images over 500 KB

    2 images weigh 1.7 MB together. On a phone connection a single image that size takes seconds.

  • 1 image far larger than shown

    53 KiB

    1 image is downloaded at several times the size a phone draws it, for example Artboard_1_44bedbee-2216-4ae0-b3c5-74a88c1e621b.jpg at 1,537 px wide, shown at 390 px. Resized copies would save about 53 KiB.

  • About 1.2 g of CO₂ per visit

    1.18 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.18 g of CO₂e: 142.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

Accessibility

9 to fixGoogle 7787
  • Invalid ARIA attributes

    1 element use ARIA attributes their role does not allow, which confuses screen readers.

  • Certain ARIA roles must contain particular children (1 element)

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

  • Hidden but focusable

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

  • ARIA input fields must have an accessible name (1 element)

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

  • Interactive controls must not be nested (1 element)

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

  • 1 tap target too small

    1 tap target is too small or too close together to hit reliably with a finger.

  • 4 images without alt text

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

  • Alternative text of images should not be repeated as text (6 elements)

    Alternative text of images should not be repeated as text: 6 elements on the page fail this check, rated minor by axe-core.

  • Elements marked as presentational should be consistently ignored (1 element)

    Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

1 checks passed
  • 52 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 61 WCAG 2.2 A/AA and best-practice rules on the phone render: 52 passed and 9 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

1 to fixGoogle 9295
  • 3 H1 headlines

    There are 3 <h1> headlines (“”, “” and “”). One clear main headline is easier for people and search engines.

  • 46 internal links, 7 external

    The homepage links to 46 pages on lestudiobon.com and 7 external pages.

7 checks passed
  • Meta description: 97 characters

    Your meta description is 97 characters: “Rencontrez de nouvelles cultures grâce aux œuvres colorées et aux histoires originales de Mr Bon.”.

  • Title: 63 characters

    Your title is a healthy 63 characters: “Le Studio Bon | Affiches, livres & cartes postales sur le Japon”.

  • Canonical URL set

    The canonical URL is https://www.lestudiobon.com/.

  • Structured data in place

    Structured data found: Organization and WebSite.

  • Open Graph tags complete

  • XML sitemap found

    Your XML sitemap is reachable at https://www.lestudiobon.com/sitemap.xml.

AI search readiness

100
  • No llms.txt

    There is no https://www.lestudiobon.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.

2 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 4 of 6 facts

    Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.

Other pages

2 to fix90
  • 1 page without a meta description

    https://www.lestudiobon.com/collections/fait-main has no meta description, so Google writes the search snippet from whatever text it finds.

  • 1 page without an H1

    https://www.lestudiobon.com/pages/lauteur-en-bd has no <h1> headline, so visitors and search engines get no clear main topic.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 23 found) and read each the way a search engine does.

5 checks passed
  • Linked pages load

    3 pages of 15 loaded without an error (the rest turned automated requests away).

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 3 pages that loaded have a <title>.

Best practices

1 to fixGoogle 9693
  • 1 JavaScript error while loading

    1 error was logged to the browser console while the page loaded, for example “Shopify's Google Analytics stub called with: [array Array] See https://help.shopify.com/manual/promoting-marketing/pixe…”.

2 checks passed
  • Tap targets are thumb-sized

    20 of 22 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

4 to fix57
  • 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 social proof

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

  • No direct contact details

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

  • Only about 149 words

    The homepage has only about 149 words of visible text; thin pages give Google and first-time buyers little to go on.

  • 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.

3 checks passed
  • 3 calls to action

    The homepage has 3 calls to action, for example “Contact”.

  • 7 short forms

    7 short forms (1 field at most) are right on the homepage.

  • Analytics in place

    Analytics detected: Google Tag Manager and Google Analytics.

Privacy and tracking

1 to fix
  • 5 trackers load before any consent

    5

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Pinterest Tag (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.

  • 13 cookies set on arrival

    13

    Opening the homepage sets 13 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.

  • 12 other companies contacted

    Loading the homepage contacts 12 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 lestudiobon.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
