Mixed Content Check: Securing Your HTTPS Website

The "Mixed Content Checker" service is a vital tool for ensuring the complete security and trustworthiness of your website, especially after migrating to HTTPS. It allows you to scan a web page and identify all resources (images, scripts, stylesheets, videos, audio, iframes, etc.) that are mistakenly loaded over the insecure HTTP protocol while on a page operating over HTTPS. This phenomenon is called mixed content and can severely undermine SEO optimization efforts and overall site security.

Why Mixed Content Matters for Security & SEO

1. Loss of User Trust

   Website visitors, seeing a security warning, may refuse to interact with the resource (e.g., entering personal data or making purchases). This directly affects user behavior factors and conversion rates.

2. Lower SEO Ranking

   Google has long announced HTTPS as a ranking factor. Sites with mixed content are not perceived as fully secure, which can negatively impact their positions in search results. This is especially important for online stores and websites handling sensitive data.

3. Real Security Risks

   Unencrypted content can be intercepted, modified, or replaced by attackers. This opens the door to various attacks, including XSS (Cross-Site Scripting) and MitM (Man-in-the-Middle attack), even if the page is loaded over HTTPS.

4. Functionality Issues

   Some browsers may block the loading of active mixed content (e.g., scripts), which can lead to incorrect operation or display of individual elements of your website.

How Our Mixed Content Checker Works:

• Page Loading

  We request the HTTPS URL you provide and retrieve the full HTML code of the page.

• HTML Parsing

  Using powerful parsers, the entire HTML code of the page, as well as dynamically loaded content if possible, is analyzed.

• Resource Identification

  All links to external resources (images <img>, <script>, <link>, <iframe>) are identified.

• Protocol Check

  Each of these resources is checked for the use of the HTTP protocol.

• Report Generation

  You receive a structured report with a list of all found HTTP resources, their HTML tags, and attributes, making it easy to locate and fix the problem.

Tips for Fixing Mixed Content:

• Always use HTTPS links

  When creating links to any resources (even your own or trusted external services), always specify https://.

• Update Links in CMS/Code

  Check your Content Management System (CMS) and code for http://-links. Use relative or protocol-relative URLs (e.g., //example.com/resource.jpg) instead of absolute URLs.

• Redirects

  Ensure all old HTTP versions of resources redirect to their HTTPS equivalents.

• Regular Checks

  Use our Mixed Content Checker after any significant changes to the site to ensure the problem does not recur.
