deltabrands.fr website review

14 images could be 892 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.8 s faster on a phone.

30 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.5 s.

Your mobile performance score is 64 (desktop: 76). Pages that score under 90 lose visitors before the first paint.

About 127 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 400 ms).

About 275 KiB of JavaScript is downloaded but never used on this page.

60 files are served with short cache lifetimes, so returning visitors download them again (64 KiB).

6 third-party services load with your homepage (Google Tag Manager, mailjet.com and mj.am and others), adding 323 KiB and 211 ms of main-thread time.

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

35 KiB could be saved by minifying JavaScript.

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.

3 KiB could be saved by minifying CSS.

Your largest element takes 6.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (2.7 s).

Visually, the page fills in at 8.0 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 10.2 s. Good is under 3.8 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

32 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.

Your homepage downloads 2.8 MB in 115 requests on a phone: images 1.3 MB (25), fonts 627 KiB (20) and scripts 604 KiB (33). Under 2 MB keeps phones on slow connections fast.

8 images (1.1 MB) are 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.

3 images are downloaded at several times the size a phone draws them, for example Slider Majeur - Delta [NEW](2).jpg at 2,400 px wide, shown at 390 px. Resized copies would save about 256 KiB.

4 images further down the page (351 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.79 g of CO₂e: 94.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 elements use ARIA attributes their role does not allow, which confuses screen readers.

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

2 frames have no title, so screen-reader users cannot tell what they contain.

1 element hidden from screen readers can still receive keyboard focus.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.deltabrands.fr/sitemap.xml, so Google discovers your pages only by following links.

Your <h1> is empty.

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

The homepage links to 39 pages on deltabrands.fr and 5 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.

/en/contact-us, /en/content/22-faq, /en/content/category/4-retail, /en/content/33-livoo, /en/content/34-scholtes and /en/content/35-onli and 7 others are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

/en/content/category/4-retail, /en/content/33-livoo, /en/content/34-scholtes, /en/content/35-onli, /en/content/36-xmoove and /en/content/37-hdelite and 5 others have no meta description, so Google writes the search snippet from whatever text it finds.

/en/content/22-faq has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

14 of 49 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

3 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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.

Opening https://deltabrands.fr goes through 2 redirects before the homepage loads.

1 link go through two or more redirects, for example https://www.deltabrands.fr/en/612-plateau-aperitif-avec-pieds-3523930104695.html.

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.

deltabrands.fr 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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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

The homepage carries about 447 words of visible text.

DMARC is set to p=none, so mail pretending to be deltabrands.fr is still delivered. Add a report address, check the reports, then move to quarantine.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 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.

Opening the homepage sets 6 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
