How Google handles a Blog migration?

Hi,

I am using a old version of boastmachine blog software and want to migrate to Wordpress keeping my orginal content in place by exporting and importing the data in the new blog. URL will stay the same

My question is how am I going to migrate to wordpress and not get banned because of duplicated content (cache).

What is the best way to set up a new blog infrastructure using same content and still get indexed by google (new indexed). Now I have a lot of indexed urls (+4000) and i want to keep them because adsense loves it!

Domain + index is 1,5 year old.

Thanks in advance

 

I think Google will simply reindex your pages and you will not be penalized(if you take down the old blog).

 

Use 301 redirects. Or simply take down the old blog once the data is moved.

WordPress has a very good import function.

 

Are u changing the URL (domain name) too? If no, than nothing to worry as long as the URL structure will remain the same (at least thats what you said).

 

as mentioned above just use redirects. I do it in my htaccess.

301 is a permanent redirect. Google finds this and it updates it's own data. your old urls will change to the new ones all the way through.

For example, my old theme was /sg_distro and the old comments page was /comments.

the new theme is /en and the new comments page is /story-details

since all the info after that is the same, and will be for you too, I just used this to re-write the URL

RewriteCond %{QUERY_STRING} ^/sg_distro/comments/([^/]+)/$ 
RewriteRule ^index\.php$ http://www.hillaryproject.com/index.php?/en/story-details/%1 [R=301,L]

Code (markup):

 

Unless you can do a re-direct, Google is likely to see it as duplicate content. Even if you remove the old blog, it will still be indexed and i odn;t know of a way of telling Google that the site no longer exists.

I moved my blog a long time ago, and the old blog is still indexed, and the new one does not come up in search results...
