Is HTTPS Good for SEO?

Yes.

Google acknowledges websites that are certified, trusted, and secure.

HTTPS enhances privacy and security by encrypting communications and transactions on your site. Because HTTPS enables users to verify that they are on the correct site, it improves user experience, which is the driving force behind SEO.

However, to ensure traffic does not suffer when switching from HTTP to HTTPS, you should communicate to Google that the website has moved.
