We migrated our website to HTTPS everywhere and we have setup a 301 redirect on all the pages when the protocol is HTTP. However, one of the SEO experts who is helping us with all things SEO sent us the following email:
Currently I have found a workaround where I'm using https as the base URL as 301 redirect to https has removed all http pages from Google index which means I'm starting from scratch as far as indexing is concerned, because of this redirection and removal of all http pages from Google index, traffic numbers are affected and I'm working hard to restore them.
Is this true? Does Google lose all the indexed pages from HTTP when HTTP is migrated to HTTPS using a 301 redirect?
