+John Mueller Hi John, does the rating of the SSL certificate impact the ranking boost? For example does a A rating HTTPS SSL certificate give a bigger ranking boost than a B rating SSL certificate? Or as long as the SSL certificate is valid and comes from a good authority (green locker) there is no ranking boost difference on class A, A-, B, C certificates?
