On a side note, I want to tell you this, because it is not in the Spin Rewriter FAQ as far as I know, but you will be limited to 300 API requests per day. This has proven to be more than enough for the number of projects we are setting up every day, which is a lot, so I don’t think you will have a problem with it either, except your link building campaigns every day are in the hundreds.
So you are still doing it? I have stopped using spin content after panda update way couple of years ago. As content become king and the user expereince the key to earn website authority, I started focusing on writing more meaningful and engaging content. I never cam across any spinner that time which makes total sense after spinning. The spin content either looked very bad or it needed manual review. I forgot the name of the spinner tool as well. Looking forward for replied from more experts here as it could be an eye opener for me if spinning still works.
From personal experience Spin Rewriter is the best! like I still use it today. Its so easy to use (Just copy paste and the program do everything) Because of this tool I managed to schedule content and articles for 3 years, do you know how much time and money I’ve saved?!?! A LOT!!! Also i high recommend you pick their mothly plan if you are still in doubt
It has helped me to get high quality content fast without having to outsource the spins. I used to spend hundreds a month just on getting article spins for all my client sites and SEO campaigns. It's very effective on getting amazing spun variations of highly relevant and high quality content quickly. You can also go back and use them again in the future since it archives them. I love that. (TIP) Spin 10 completely different titles with your articles for ultimate diversity!
