Fix plan

Written by gpt-4o-mini from the scan findings

Your website needs improvement, particularly in redirects, title tags, and sitemap coverage. Prioritize fixing these issues to enhance overall performance.

  1. 1

    Fix Redirect Chains

    Why: Chained redirects can slow down page loading and confuse search engines.

    How: Rewrite your server rules to remove chain redirects, making each URL resolve in one hop.

    Checks: redirects

  2. 2

    Resolve Non-200 Responses

    Why: 580 pages returning non-200 responses impact user experience and indexing.

    How: Audit these pages, correcting broken links, ensuring proper response codes, and optimizing assets.

    Checks: status-codes

  3. 3

    Add Missing Title Tags

    Why: Missing or duplicate title tags reduce visibility and click-through rates on search results.

    How: Create unique and relevant title tags for pages without them, ensuring lengths are optimal.

    Checks: titles

  4. 4

    Improve Meta Descriptions

    Why: Meta descriptions help improve rankings and click-through rates; many are missing.

    How: Write engaging meta descriptions for pages lacking them, keeping within recommended lengths.

    Checks: meta-descriptions

  5. 5

    Enhance Sitemap Coverage

    Why: Key pages are not listed in your sitemap, affecting their visibility to search engines.

    How: Update the sitemap to include all relevant and crawled pages, ensuring it reflects your content accurately.

    Checks: sitemap-coverage

  6. 6

    Reduce Heavy Assets

    Why: Large images slow down page load times, affecting user experience and SEO.

    How: Optimize or compress heavy assets to reduce their size without losing quality.

    Checks: heavy-assets

Security review

Written by gpt-4o-mini from 16 checks over the crawl

Your website has several security vulnerabilities that could expose it to clickjacking attacks and unauthorized cookie access. Additionally, it lacks some headers that control referrer information and permissions. These issues should be prioritized for remediation to enhance your site's overall security.

  • 0 high
  • 2 medium
  • 1 low
  • 1 info
  1. 1

    Missing X-Frame-Options HeaderMedium

    Why it matters: Without the X-Frame-Options header, your pages can be embedded in frames on other sites, making them susceptible to clickjacking attacks.

    Fix: Add the header `X-Frame-Options: SAMEORIGIN` to all HTML responses.

    Evidence: Clickjacking protection

  2. 2

    Missing HttpOnly and SameSite Cookie FlagsMedium

    Why it matters: Cookies without these flags can be accessed by scripts or sent during cross-site requests, increasing vulnerability to attacks.

    Fix: Set the flags as follows for any cookies: `HttpOnly`, `Secure`, and `SameSite=Lax` or `SameSite=Strict` where applicable.

    Evidence: Cookie flags

  3. 3

    Missing Referrer PolicyLow

    Why it matters: Without a referrer policy, sensitive URL information may be shared with external sites when users navigate away.

    Fix: Add the header `Referrer-Policy: no-referrer` or another appropriate value to mitigate this risk.

    Evidence: Referrer policy

  4. 4

    Missing Permissions Policy HeaderInfo

    Why it matters: Without this header, unwanted browser features (e.g., camera, microphone) remain accessible to scripts.

    Fix: Add the header `Permissions-Policy: geolocation=(), microphone=(), camera=()` to limit feature access.

    Evidence: Permissions policy

What the checks found

  • FoundClickjacking protectionMedium

    493 of 2613 HTML pages send x-frame-options. Without X-Frame-Options (or a CSP frame-ancestors directive) the pages can be embedded in a frame on another site and overlaid with invisible controls.

    493 of 2613 HTML pages send referrer-policy. Without a Referrer-Policy the full page address, including any query string, is sent to every site a visitor clicks through to.

    • https://ntcore.io.vn/contact/ → no referrer-policy
  • FoundPermissions policyInfo

    No HTML page sends permissions-policy. A Permissions-Policy header turns off browser features the site does not use (camera, microphone, geolocation), limiting what an injected script could do.

    • https://ntcore.io.vn/contact/ → no permissions-policy
  • FoundCookie flagsMedium

    1 of 2 cookies are missing protective flags. Without HttpOnly a script can read the cookie; without Secure it travels over plain HTTP; without SameSite it is sent on cross-site requests.

    • wordpress_test_cookie (set by https://ntcore.io.vn/ths/?redirect_to=https%3A%2F%2Fntcore.io.vn%2Fscan-to-pdf%…) lacks SameSite
  • NoteThird-party scripts

    Scripts run from 3 other domains without Subresource Integrity, so a compromise of any of them changes what runs on this site. (Tag managers and analytics rarely support SRI; a Content-Security-Policy that names these hosts is the usual control.)

    • www.googletagmanager.com (40 script tags)
    • pagead2.googlesyndication.com (40 script tags)
    • cdnjs.cloudflare.com (1 script tag)
  • NoteSensitive paths in robots.txt

    robots.txt lists 2 paths that look private. robots.txt is public and does not restrict access, so it doubles as a map for anyone probing the site; those paths need real access control.

    • Disallow: /wp-admin/
    • Disallow: /cgi-bin/
