Preamble: I did my searching and reading before posting this, and to my knowledge there isn't any good info on this combination of issues. ----- We're redesigning a bank website, and I found out a lot of banks have http homepages with customer logins - and this isn't secure- page with the form on it has to be https. If there's going to be a bank login on every page the whole site has to be https. 1. Do https pages rank as well as http, all things being equal? Of course, indirect factors might make things unequal: I bet some other webmasters will accidentally create links to the http version, so https may not rank as well. 301 from the http to https would deal with this, tho, no? 2. Plus you have to prevent the duplicate content that can happen with http and https. 3. We have IBL's we don't want to lose- I know we can 301 redirect the homepage to the https version and that transfers PR etc., but we were considering doing what DNBNOR.com has done, which is use a 302 redirect- I don't know if there are any consequences to using a 'temporary' redirect long term? But the idea would be to keep the http version indexed- honestly I'm not sure there is much benefit to that, and your guys' wisdom on issue #1 above would determine that. We don't care if the site is listed https as long as there's no future SEO impact. 4. From what I can see in Google webmaster tools, choosing the preferred site does not apply to https vs http. Any help? Thanks!
