Rankings drop since switch to https

[Kellster]

Switched hosting companies, and then switched to https for the entire marketing site as a result of needing the security for the signups.  Rankings in several (most areas) have tanked since then.  Site hasn't changed otherwise, is responsive, fast, and spidered well.  See:

I FEEL like the redirection is being handled properly, but I can't be sure.  Moz reporting duplicate content on the homepage between http and https - but I honestly don't know why.

Any help - ANY - is appreciated.  Hair being pulled out, and I don't think I'll look good completely bald.

Can you explain why?  I've looked around a lot on this, and there doesn't seem to be much agreement about it.  https isn't costing anything with respect to performance, so why not do it?

I'll happily remove it from all the pages where it isn't required if its really making a difference.

OK - think it's fixed now.  But could that possibly have been the issue for ALL the site rankings?

Thanks for this help by the way.  Going to refer some friends to you ASAP for help if that's OK.  They have zero technical skill, so they need direct help.  And to be charged, of course.

After reviewing pisoftware.com, you only need https for the Login/Signup page. Why the hell would you need https for other web-pages as they are only "informational" pages; there's no transactions or sensitive information on them.

Putting the entire site in https is just a bad idea.

Kelly, I'm not seeing a redirect from the http version to the https: version. So these two sites are going to be seen as copies! ALl the internal links (on both versions) are pointing to the https: version though.

Think you need to take a look at the http: -> https: redirection.

This http request/response header checker is a useful way to test.for redirects etc: http://web-sniffer.net/

How have you tried to implement the redirection?
