Welcome to the Q&A Forum

Hello there, quick question on HTTPS downgrade to HTTP. Originally, full site was HTTPS. Redesign eliminated need for secure layer. Site currently has https 301'd to sub.domain.com. Ideally, site would live at domain.com, but with the old site having been indexed https, the security warning triggers when you visit, hence the 301 to a subdomain. Thinking possible solutions here are to a) add back in secure layer or b) 301 all old https pages to new http pages. Have I overlooked something? With (a), I will see no SEO impact, correct? With (b), can I expect impact similar to a relaunch? Have seen a lot of chatter that there is some impact in switching http to https, but not much the other way. Any help much appreciated!
