Google here officially announced that using SSL is minor ranking factor. On that page is, besides other rules, stated to
Use 2048-bit key certificates.
Does it mean that using
224-bit key ECC certificate will not have positive impact on SERP ranking because the key is not "long enough" ? It seems that ECC (Elliptic Curve Cryptography) certificates have some nice benefits (e.g. less server CPU usage and less bandwidth used, etc..).
I would like to use ECC certificates, but I fear it will not help me with Google. Or maybe I am too concerned and Google accepts any trusted SSL certificate and doesn't care about key size at all ?
