Basically...
Spinning is used when you want multiple versions of an article and when done properly then it is pretty transparent and you can't tell that it is spun.
If you are promoting a certain page then you can have an article written (some writers can write them in spinning syntax for an extra charge) and then spin it. You can then have 100, 200 or pretty much as many articles as you want that are unique and related to your page. You can either submit them to article sites, use them on bought blog posts or pretty much anything you want to do with them.
It isn't taking work away from writers, how often do writers get asked to write 100 articles that are basically written the same but unique?
People keep saying that you need decent copy on your site to keep people on there and buy whatever you are selling and spun can't be used. The spun posts aren't used on the main site, they are used elsewhere.
It isn't really classed as spam as spam is unwanted. Article Site owners want as much content as they can get as it generated them long tail traffic which generates them and clicks and in return you get a back link.
People seem to contradict, they say it doesn't work and then say what about the "Great Sites" that are not ranking because of people using these methods. Are they really that great if they are being kept off the top spot because of it?
I don't understand people saying how unethical it is and how it is wrong to use article marketing if it works? It is not like Blog or Forum Spam, the article sites are based on this kind of thing and they make money from it. Maybe I am just naive.
All the talk of cheating is a bit confusing? Is there a rule book? If it works then surely why not use it? What is not cheating?
Yes, people may use stolen content to spin but surely that is better than the person who just copies and pastes? (Not Condoning)
