HTTPS pages linking to HTTP URLs can trigger browser security warnings. It can damage user trust and hurt rankings as Google penalises mixed content.
What to do: Review the affected pages and update any internal links, images, scripts, or other resources that use http:// URLs to use https:// instead.
How to fix: Replace all http:// URLs with https:// versions where available. These links may be located in theme code, page content, app settings, or custom scripts. However, you should first verify that the HTTPS version actually works. Some older websites or third-party resources may not support HTTPS. If the HTTPS version is unavailable, you may need to replace the resource with a secure alternative, host the file on your own website, or remove it entirely. In Shopify, most mixed content warnings can be resolved by replacing http:// URLs with https:// URLs in theme code, page content, or app settings.
Note: Mixed content occurs when a secure HTTPS page loads resources or links from insecure HTTP URLs. This can trigger browser security warnings, reduce user trust, and cause certain content to be blocked by browsers. Using HTTPS consistently across your website helps ensure a secure browsing experience.
