All Findings (44)

Critical (4)

    Add Strict-Transport-Security header with max-age of at least 31536000

  • highaccessibility

    4 form fields without labels

    Add visible text or aria-label to all buttons

  • highpage experience

    Intrusive interstitials detected

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

Medium (18)

  • mediumdns

    No DKIM record found

    None of the common DKIM selectors returned a valid key. Email authentication may be incomplete.

    Configure DKIM signing with your email provider and publish the public key in DNS

  • mediumheaders

    Missing content-security-policy

    CSP header is missing. The site may be vulnerable to XSS attacks.

    Add a Content-Security-Policy header to restrict resource loading

  • mediumheaders

    Missing x-content-type-options

    X-Content-Type-Options is missing. MIME-sniffing attacks are possible.

    Add X-Content-Type-Options: nosniff header

  • mediumheaders

    Missing x-frame-options

    X-Frame-Options is missing. The site may be vulnerable to clickjacking.

    Add X-Frame-Options: DENY or SAMEORIGIN header

    Missing canonical URL

    No canonical link tag found

    Add a canonical URL to prevent duplicate content issues

  • mediumsitemap

    Duplicate URLs in sitemap

    1 duplicate URLs found in sitemap

    Remove duplicate URLs from the sitemap

    Low keyword relevance

    Only 22% of title keywords appear in body text

    Ensure the page content includes the keywords from the title

  • mediummobile

    Fixed-width elements may cause horizontal scroll

    2 elements have fixed widths > 400px

    Use max-width: 100% or responsive units instead of fixed pixel widths

  • mediumaccessibility

    Positive tabindex values found

    1 elements use tabindex > 0, which disrupts natural tab order

    Use tabindex="0" or tabindex="-1" instead of positive values

  • mediumrate limits

    No rate limiting detected

    10 rapid requests all succeeded without any rate-limit headers or 429 responses. The site may be vulnerable to abuse.

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

    No Organization JSON-LD found

    Add Organization structured data with name, logo, and contact information
