Isnt it a Spam?

Both from the hyphenated version of the domain. I don't see the one without the hypen.

 

try this
http://www.google.co.in/search?q=+bag+closing+machinery

 

ic 3 urls, 2 with the dash, 1 without. but the content of the pages is not the same.

 

yeh content is not same, they are not that much fool either. More or less the 2 domains are used to gain search rankings and have nothing to do with protecting brand identity by registering all related domains...

 

Personally I don't see the site doing too much wrong. At worst they're a bit naive when it comes to duplicate content.

 

I believe it was done on purpose, but I don't see much benefit from it at all. Google seems to switch back and forth between domains when ranking for relevance.

 

So conclusion is that its not a spam??

 

I think you don't know the definition of spam.

 

dear i know what exactly is spam but what we are debating here is that its more or less a spam. Nobody is that much fool these days to follow a complete spam. Its more or less about how to fool search engines and gain search traffic by hook or crook.

So if its not a spam it means u make 2 mirror websites and just change the content a bit....its not a spam. Am i right??

 

NO, it's not spam
