It is written everywhere that lack of original content is has a negative impact on ranking. But what is lack of original content? (I am not talking about duplicate content)
I guess if you copy other site's content, this makes sense. But, assuming one develops its own functionalities, but similar functionalities are already available on other sites, is this considered lack of original content?
Can Google decide to not index such pages (i.e., not give them a chance at all)?
Are there other definition of 'lack of original content'?
