All Findings (21)

Critical (4)

  • highsitemap

    Invalid sitemap format

    Sitemap does not appear to be valid XML

    Ensure sitemap.xml is properly formatted XML

  • highsitemap

    Empty sitemap

    Sitemap contains no URLs

    Add URLs to the sitemap

  • highpage experience

    Intrusive interstitials detected

    Reduce intrusive interstitials — they hurt mobile experience and can trigger Google penalties

  • highindexing checker

    Canonical points to different domain

    Canonical: https://www.ziggo.nl/ points to ziggo.nl

    Ensure the canonical URL points to the same domain unless cross-domain canonicalization is intended

Medium (7)

  • mediumheaders

    CORS allows all origins

    Access-Control-Allow-Origin: * allows any website to make requests

    Restrict CORS to specific trusted origins if the page handles sensitive data

  • mediumstructured data

    Missing @type in schema

    A structured data object has no @type

    Add a @type property (e.g. Organization, WebSite)

  • mediumrobots

    Important resources blocked

    robots.txt blocks /assets/ — search engines can't render the page properly

    Allow crawlers to access CSS, JS, and image resources

  • mediumtechnology

    Render-blocking scripts

    7 scripts load synchronously without async/defer

    Add async or defer to non-critical scripts to improve page load speed

  • mediumtechnology

    Mixed content detected

    2 resources loaded over HTTP on an HTTPS page

    Update all resource URLs to use HTTPS

  • mediumcontent

    Very low text-to-HTML ratio

    Text/HTML ratio is 2% (recommended: >5%)

    Increase meaningful text content relative to HTML markup

  • mediumcrawl budget

    Potential crawl traps

    Consider blocking these URL patterns via robots.txt to preserve crawl budget

Low (10)

  • lowheaders

    Add Organization schema with name, logo, and contact info

    Add WebSite schema with SearchAction for sitelinks search box

  • lowtechnology

    Many third-party domains

    19 external domains — may impact performance and privacy

    Reduce third-party dependencies or self-host critical resources

  • lowmobile

    Unresponsive images

    18 images lack srcset or responsive sizing

    Use srcset and sizes attributes for responsive images

  • lowrate limits

    No rate limiting detected

    No explicit rate-limit headers or 429 responses detected. AWS CloudFront WAF provides platform-level protection.

    Implement rate limiting (e.g., 429 Too Many Requests) to protect against brute-force attacks

  • lownews mentions

    No press or news presence

    No press pages found on the site and no external news mentions detected

    Create a /news or /press page with company updates — this builds authority and earns links

  • lowbrand checker

    No manifest.json linked — PWA features unavailable

    Add a web app manifest for installability and brand customization

  • lowbrand checker

    Missing og:site_name

    Add og:site_name meta tag for consistent social sharing
