70/ 100Needs work

On October 22, 2026 the Site Spider crawled 864 pages and 1834 assets of on.com.tr, starting from https://on.com.tr/. It scored 70 out of 100, a result that needs work. 12 of 33 checks found something to fix, led by broken links (260), heavy assets (63), meta descriptions (421); 8 checks passed. Most of the points went to broken links (−8), heavy assets (−6), meta descriptions (−5.2). 13 checks found something the score does not count, listed as noted. 4 checks were not run because the crawl fetched nothing for them. The list below shows each check's result, the fix plan, when present, explains what to do first, and the security review at the end of the page covers headers, transport, libraries and exposed files.

Fix plan

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

The website has several broken links, redirect issues, and missing meta descriptions that need immediate attention to improve SEO performance. Addressing these will enhance user experience and search visibility.

  1. 1

    Fix Broken Links

    Why: 1988 internal links point to broken URLs, harming user experience.

    How: Identify and replace or remove broken links on affected pages.

    Checks: broken-links

  2. 2

    Resolve Redirect Issues

    Why: 204 redirecting URLs, including chained redirects, can impact SEO and site speed.

    How: Simplify redirects to minimize chains and ensure all redirects are necessary.

    Checks: redirects

  3. 3

    Add Missing Meta Descriptions

    Why: 421 pages lack proper meta descriptions, affecting search results visibility.

    How: Create unique meta descriptions for affected pages, ensuring they reflect the content accurately.

    Evidence: 3 pages share the meta description "ON Dijital", which usually means one template writes it for all of them.

    3 pages affected

    Depends on: If these pages really are the same content, the duplicate meta description is a symptom: canonicalise them to one URL instead.

    Checks: meta-descriptions

  4. 4

    Improve Title Tags

    Why: 305 pages have title issues; many are too short or duplicated.

    How: Revise title tags to be unique, descriptive, and adequately long for SEO.

    Checks: titles

  5. 5

    Enhance Sitemap Coverage

    Why: Several URLs in the sitemap are broken or redirecting, causing potential crawls issues.

    How: Update the sitemap to remove broken URLs and ensure accuracy.

    Checks: sitemap-coverage

  6. 6

    Reduce Size of Heavy Assets

    Why: 63 assets larger than 500 KB can slow down the site’s loading speed.

    How: Optimize or compress heavy assets used on multiple pages.

    Evidence: 3.8 MB of script, loaded by 19 pages, so every visitor to any of them downloads it.

    19 pages affected

    Depends on: If it is a download rather than part of the page, weight matters less; move it out of the page instead.

    Checks: heavy-assets

Security review

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

The website on.com.tr has several security issues that need addressing. It lacks a Permissions-Policy header, and important cookie flags are missing, which can expose user information. Additionally, some third-party scripts do not implement Subresource Integrity, risking unauthorized script execution.

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

    Insecure Cookie FlagsMedium

    Why it matters: Cookies without Secure, HttpOnly, or SameSite flags are vulnerable to theft and misuse, endangering user sessions.

    Fix: Set the Secure flag for the following cookies: .AspNetCore.Mvc.CookieTempDataProvider, .AspNetCore.Session, and .AspNetCore.Antiforgery.VyLW6ORzMgk.

    Evidence: Cookie flags

  2. 2

    Third-Party Scripts without Subresource IntegrityLow

    Why it matters: Scripts from external domains can be modified, exposing your site to potential harm.

    Fix: Implement Subresource Integrity for scripts loaded from www.googletagmanager.com and on.api.useinsider.com or consider a Content-Security-Policy to control script sources.

    Evidence: Third-party scripts

  3. 3

    Missing Permissions-PolicyInfo

    Why it matters: Lack of Permissions-Policy leaves browser features enabled that could be exploited by malicious scripts.

    Fix: Add a Permissions-Policy header to your HTML pages with directives to disable unused features.

    Evidence: Permissions policy

What the checks found

  • 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://on.com.tr/ → no permissions-policy
    • https://on.com.tr/urun-ve-hizmet-ucretleri → no permissions-policy
    • https://on.com.tr/en → no permissions-policy

    • https://on.com.tr/hesaplar/yatirim-hesabi/gumus-hesabi → no permissions-policy
    • https://on.com.tr/yatirim/platin-hesabi → no permissions-policy
    • https://on.com.tr/yatirim/paladyum-hesabi → no permissions-policy
    • https://on.com.tr/krediler/dijital-ihtiyac-kredisi → no permissions-policy
    • https://on.com.tr/krediler/tasit-kredisi → no permissions-policy
  • FoundCookie flagsMedium

    3 of 5 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.

    • .AspNetCore.Mvc.CookieTempDataProvider (set by https://on.com.tr/urun-ve-hizmet-ucretleri) lacks Secure
    • .AspNetCore.Session (set by https://on.com.tr/urun-ve-hizmet-ucretleri) lacks Secure
    • .AspNetCore.Antiforgery.VyLW6ORzMgk (set by https://on.com.tr/ihbar-suistimal-etik-bildirim-hatti) lacks Secure
  • NoteThird-party scripts

    Scripts run from 2 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)
    • on.api.useinsider.com (40 script tags)
13 checks passed
  • OKHTTPS

    All 650 crawled pages were served over HTTPS.

  • OKHTTP Strict Transport Security

    strict-transport-security is set on all 650 HTML pages.

  • OKContent Security Policy

  • OKClickjacking protection

    x-frame-options is set on all 650 HTML pages.

  • OKMIME sniffing protection

    x-content-type-options is set on all 650 HTML pages.

  • OKReferrer policy

    referrer-policy is set on all 650 HTML pages.

  • OKSoftware version disclosure

    No Server or X-Powered-By header is sent.

  • OKMixed content

    No HTTPS page loads a script, stylesheet, font or image over plain HTTP.

  • OKForms over HTTPS

    80 forms found, all on HTTPS pages posting to HTTPS addresses.

  • OKVulnerable JavaScript libraries

    3 library versions recognised, none with known vulnerabilities.

  • OKKeys and secrets in page code

    No API keys, tokens or private keys were found in the sampled HTML and scripts.

  • OKExposed files and listings

    None of the crawled URLs is a configuration file, backup, dump, repository folder or directory listing.

  • OKSensitive paths in robots.txt

    robots.txt does not point at admin, backup or private paths.
