In my case, moving to wordpress isn't instantly. I already changed my blogger to the custom domain, but i'm still setting things up on WP and don't know how much long it will take until ready to move. So blogger still holds my blog under a new domain. Since last 8 days, when I changed the domain, my traffic dropped for half and I'm without sitemap. Questions: Should I set a new blogger sitemap for the new domain? what about the original blogspot domain does it need one too redirecting to the new domain? what about the redirect true or false parameter and in each one ?
If I will have in one week or so the new WP blog online is it really necessary? Beside all of this I'll want to have my domain with non WWW which I have now on blogger with.
Am I compromising the whole process of migrate my blog keeping the search engines ranking? One thing for sure it's the ranking already dropped.
Would like to have an advice. Thanks in advance.
