An security certificate is also called a SSL Certificate. When a site has an SSL Certificate the web address (URL) is prefixed with HTTPS instead of HTTP. In 2018 Google made a decision to add SSL to the ranking algorithm it uses as a mandatory item. This has meant that websites have needed a SSL Certificate to help with Search Engine Optimisation.
Apart form helping with your Search Engine Rankings having a Security Certificate also helps with:
- Protecting your data on your website
- Your website Identity is authenticated
- Helps with accepting online payments
- Improves customer trust.
