Hi I reasontly bought a high traffic blog. it's in blogger and half of the traffic from Google. it's a none English site and 99% local traffic. I am thinking to move this to wordpress. if I move the site from blogger to wordpress, will it affect for Search engine ranking ? thanks.
I don't think Blogger allows you to redirect your URL to anywhere else so you'll probably loose everything if you switch overnight. I would recommend, if you have to use wordpress, to go ahead and start using the wordpress platform, but post all of your posts on both sites for a while. Announce to your readers that you're moving to a new blogging platform and give them the link during this time when you are posting on both blogs. Then, start posting only a link to your wordpress blog on your blogger blog until you have enough traffic to stop posting at blogger altogether. Write one last post on Blogger letting late comers know that you've switched platforms and you should be good!
