Images and page weight

100

  • About 0.2 g of CO₂ per visit

    0.16 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.16 g of CO₂e: 19.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 checks passed

  • Page weight: 584 KiB in 5 requests

    584 KiB

    Your homepage downloads 584 KiB in 5 requests on a phone: scripts 326 KiB (1), fonts 127 KiB (1) and stylesheets 123 KiB (1). That is a lean page.

  • 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.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

Google 98100

  • Headings skip levels

    Headings skip levels (h1 → h5), which makes the page harder to scan with a screen reader.

2 checks passed

  • Every image has alt text

    All 1 image in the HTML carry an alt attribute.

  • 34 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 35 WCAG 2.2 A/AA and best-practice rules on the phone render: 34 passed and 1 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

4 to fixGoogle 10084

  • 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 (18 characters)

    Your meta description is only 18 characters: “Renson new website”. 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 X (Twitter) card tag

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

  • 26 internal links, 0 external

    The homepage links to 26 pages on renson.net and 0 external pages.

4 checks passed

  • One H1 headline

    Your main headline reads: “Welcome to Renson!”.

  • Title: 31 characters

    Your title is a healthy 31 characters: “Renson: Creating healthy spaces”.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://renson.net/pro/nl-nl/sitemaps-2-sitemap.xml.

AI search readiness

1 to fix83

  • 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 /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.

1 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.

Other pages

2 to fix90

  • 5 pages share 2 titles

    /fr-be, /fr-fr and /fr-lu all use the title “Une vie saine à l’intérieur et à l’extérieur | Ventilation, protectio…”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

  • 5 pages share a meta description

    /de-at, /de-de and /de-lu use the same meta description. A description written for each page earns more clicks.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 25 found) and read each the way a search engine does.

6 checks passed

  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

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

  • Every page has a meta description

    All 15 pages that loaded have a meta description.

  • Every page has an H1

    Each page we checked has a main headline.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

1 to fixGoogle 10093

  • 25 small tap targets

    25 of 26 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • Missing source maps

    Large scripts ship without source maps.

2 checks passed

  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

6 to fix25

  • 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.

  • No analytics detected

    No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

  • 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 57 words

    The homepage has only about 57 words of visible text; thin pages give Google and first-time buyers little to go on.

  • 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.

Privacy and tracking

  • 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.

1 checks passed

  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).

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 renson.net, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
