Images and page weight

100

  • About 0.06 g of CO₂ per visit

    0.06 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.06 g of CO₂e: 7.3 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: 218 KiB in 15 requests

    218 KiB

    Your homepage downloads 218 KiB in 15 requests on a phone: fonts 112 KiB (3), HTML 64 KiB (1) and images 32 KiB (8). 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

3 to fixGoogle 8896

  • 17 text elements with low contrast

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

  • 23 links without text

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

  • 1 form field without a label

    1 form field has no label, so screen readers announce an empty box and autofill guesses.

2 checks passed

  • Every image has alt text

    All 16 images in the HTML carry an alt attribute.

  • 45 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 48 WCAG 2.2 A/AA and best-practice rules on the phone render: 45 passed and 3 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

1 to fixGoogle 9298

  • 1 link with vague text

    1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

  • 124 internal links, 6 external

    The homepage links to 124 pages on jan-pro.com and 6 external pages.

8 checks passed

  • Meta description: 149 characters

  • robots.txt in place

  • XML sitemap found

    Your XML sitemap is reachable at https://jan-pro.com/sitemap_index.xml.

AI search readiness

1 to fix88

  • Organization data is thin (3 of 6 facts)

    Your Organization JSON-LD is missing url, 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.

  • No llms.txt

    There is no https://jan-pro.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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (788 words), so crawlers that don't run JavaScript still read it.
