It’s quite simple to identify whether your site has a security certificate, and there are a few different ways to do this.
The first way is to simply look at your website’s URL. Websites that are secure will show HTTPS, and those that are not will only show HTTP.
If it shows as HTTPS secure, you may be fine. However, you will need to verify that the http:// version redirects to the https:// version, and that all hard-coded internal links on your site are directed to https://.
If you have the Chrome browser installed, it’s quite easy to tell as well. All you have to do it enter a URL in the address bar, and any site that is unsecured will be clearly displayed as such, showing either a red “Not Secure” status, or, until July, an i in a circle icon.
Don’t worry, even a few very well-known sites were caught off guard by Google’s update. But there’s no time like the present to secure your site.
