SSL certificates are a must-have for websites on today’s web. Not only are they vital for creating secure connections between your users’ devices and your site’s server, but it’s basically mandatory for many web browsers. If you opt out of installing an SSL, major web browsers like Chrome and Firefox will greet potential visitors with a warning that your site is “not secure”. It’s no surprise, then, that more websites than ever are secured with SSL. Fix your website’s insecure content. 5 Amazing Affiliate sites to make money online.
That said, sometimes issues can arise even when you install an SSL certificate that can prevent the creation of a secure connection. One of those issues is insecure content. fix your website’s insecure content
HTTP and HTTPS connection, fix your website’s insecure content
To explain insecure content, you’ll first need to understand a little bit more about the difference between HTTP and HTTPS connections. You’ve probably noticed both appear in your web browser’s address bar at some time or another as a prefix of the website you were visiting. HTTP is short for Hypertext Transfer Protocol and allows for data transfer over the web between a web server and a client, such as a web browser. HTTPS, which is short for Hypertext Transfer Protocol Secure is much the same except with a vital difference — the data transfer is encrypted, meaning that no third parties can access the information sent over this connection.
When a website has an SSL certificate, its web pages will load via the HTTPS protocol. At least, that’s how it’s supposed to work. However, when a website features insecure content, your site will likely load through HTTP and your users may be hit with a message like, “This page contains both secure and nonsecure items”.
Encountering such a message after going through the effort of installing an SSL is understandably frustrating. Wasn’t the SSL certificate supposed to make everything secure?
As we’ve talked about before on this blog, SSL certificates aren’t a quick fix for all your site’s security needs. And if your site already has issues, it’s not going to override that. Insecure content usually occurs due to an issue with your website’s coding and has anything to do with an SSL certificate.
What is insecure content?
When we talk about website content in this context, we’re talking about everything that makes up the pages on your site, from CSS, JavaScript, and HTML to images and videos.
Before a webpage is loaded on your browser, it sends a message to the server, requesting the content that makes up that page. Most web pages are made up of a combination of the content we previously mentioned. Each resource is downloaded via separate requests. Once the content has been downloaded, the page is displayed in your browser.

Insecure content occurs when some of the content downloaded is loaded via HTTP rather than HTTPS. When your website features both secure and insecure content this is known as mixed content. This common reason for mixed content is that some of your site’s content is actually hosted on a different website without an SSL certificate, so they’re loading over a connection that isn’t encrypted. Another possible scenario is that the external content is hosted on a site with an expired or invalid SSL.
Why is insecure content such a big deal?
If any of the content on your site loads via an HTTP connection. Then your whole site will load through HTTP by default — even if you have an SSL certificate. SSL certificates can only encrypt the connection between content hosted on your server and a user’s browser, and not content hosted elsewhere.
A website with mixed content could leave its users susceptible to man-in-the-middle attacks. Which is when malicious across intercept and modify the connection between a browser and the server.
Beyond that, mixed content can affect website traffic and site usability. Users could potentially be greeted with a message warning them about the mixed content on your site. And may understandably opt not to continue.
Many browsers have even started blocking insecure content entirely. In a January 2021 update, Google Chrome by default started blocking the HTTP file downloads of images, docs, and PDFs from HTTPS sites. Even if users can access your site. If your site depends on many unsecured resources, it may be left virtually unusable.
