If i Publish copy content with source(where i copied from) in blogger google treated this content as copy content or ?
Im quite sure it is treated as copy content.,I have heard it is always better to use original content if possible.,it helps with ranking in google
You can put the source, but is always copied content for the search engines, unless you have an unbeatable amount of traffic.
Same contents from different url are treated as duplicate content. I think, the point is clear to you.
Definetly it will be treated as copied content. But here is a twist you can add why dont you spend 15 minutes on that content you copied and then re-write it and then post it on your blog this way there chances are low
If you're content is copied from anywhere that is already indexed in Google's database it will count as duplicate content. It doesn't necessarily affect your ranking but if you want to improve your rankings you're going to have to generate unique content. If the content you are copying isn't indexed then it will be considered unique.
