With Google Chrome flagging up insecure sites, you can check whether a site is HTTPS (encrypted) Using free services like SSL Checker from High-Tech Bridge and then encrypting it using free services such as Lets Encrypt. If your website is not redirected to HTTPS, Google will mark the website as in-secure. Some external content (e.g. iframes, images, scripts, etc) that are loaded from external HTTP resources, without HTTPS, may find Google marking this site down.”]
