On my recent blog which probably a month ago or so I shared the best way how to share my blog from Globlan NPN to Blogger.
I recommended do post it manually rather than copy and past the link this way whoever is reading your blog on Blogger will read the entire post.
Now, I just discovered another way which is…
When you open one of your blog from NPN you can copy and paste its url.
When you get to your blogger account what you can do on the title is put a {Bracket} and type the title of your blog and insert your Global NPN url of the blog that you wish to share.
You can insert a photo also if you wish.
My choice of sharing my blog is copy and past the entire blog, but now that I discovered another way.
Either one will work, it is just a matter of your preference.
