How thorough should you spin articles?
But I find that spinning the words is unnecessary. I do not think it will be that much more effective getting down to each word. I have many sites ranked in the top 3 for their keywords and most of the time I only needed one spun article for the backlinks of each one.
I also use Unique Article Wizard for backlinks and the way they spin articles is actually much easier because all you do is rewrite the entire article 2 more times. The articles are less unique but they still produce great results maybe because of the value you get from the sites they post to.
I guess the point of this thread was to share some advice and find out what others do when spinning articles and if they find success doing it.
