Moving to https and back to http, would it it hurt?

[TVape]

We have redirected everything on our blog from http to https. Our blog is in a subfolder so that now it looks like this: https://ourdomain/blog; But everything else i.e. our shop continues to be on http at http://ourdomain

We are wondering:

1- Does the domain authority for SEO purposes have different values for the http and the https version of a domain?

2- If yes, is there a way to check the difference in authority between the http and the https version?

3- If we do have a higher authority on our http version (as historically we have been mostly on our http), would it make sense to go back to the http for the blog to enjoy that authority too?

4- Would changing our mind and going back to http after a few months of just having moved to https from http send any negative signals to Google? Would Google care if we do a back and forth essentially?

Many thanks!

I wouldn't recommend going back to HTTP. There shouldn't be any difference in authority between HTTP and HTTPS, and Google has stated that they consider HTTPS to be a positive ranking signal.

Matt has summed it up, but my question is..why don't you get a wildcard certificate?

It will make it much easier and if you ever move your website to a CDN network, an HTTPS website with a wildcard certificate makes the process smooth!
