Only standard WordAI spinner showed 12% match for me in Copyscape which is very good I think. Also I will add that for SPAM links in general you don’t need any quality at all. if Google crawler can’t find connection with other spinned articles – goal achieved. Sorry, but I don’t see that with expensive spinners as Copyspace shows that in plain sight.
For this purpose, humans have created numerous rewriting tools to save time and use all words available in the English dictionary. Rewriting tools use millions of synonyms made available to them through artificial intelligence and instructions given by the human mind. If you hire the services of a content writer to rewrite/create content for you, they will charge you a lot. Big organizations can afford this but small startups and students can never afford the services of professional writers.
Whe i first accessed the spin rewriter tool, i had one purpose on in mind, generate endless content to drive traffic, build authority and build backlinks. This is the way i found to move forward with any online business. I use the tool for 3 different purposes, money pages, 2nd tier backlinks and 3rd tier backlinks and the settings presented in the rewriter accomodate all three options flawlessly.
