Avoiding Duplicating Content Isn't Enough; Google Looks for Differentiation
Remember article spinners? I really hope you're not still using them.
Spinners are like an automatic thesaurus, changing out certain words just enough to make the article different enough that you hope Google won't catch on.
Another tactic used real people, often underpaid outsourced workers from developing countries, to change the structure of an article and trade out a percentage of words so you could call an article “unique.” Of course, article spinning typically generates garbled, unintelligible garbage
. It did work for a while a few years ago, to fool the search engines into thinking a site had more unique content than it actually had. No longer.
