Well, most writers write fresh content this way, except for the spinner chief part. Instead of just copying whatever comes up on the first 5 spots, you could curate the best writeups on your topic, put it together and try to improve whatever is already there on the internet. Once your new post is live, go email everyone who has linked out to the sources you used and tell them you have a better one just published. You may get some solid links this way.
I've ranked websites in the past with spun content, and now they are still on #1 position of google. First year (2014) google found me because my spun was really bad, many paragraphs were just copied and my position drop from #2 to around #20 after a panda update. Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
If you have not used a spinner before then I would suggest that you first use something that require more human imput like The Best Spinner or Spinner Chief in order to understand the basic principles. However if you must go fully auto then I would suggest you go for Wicked Article Creator. I have it and understand it is similar to wordAI but a one off fee of $47.
Most of our customers have no problem making the less than $2 per day it costs to use WordAi. Artificial intelligence isn't cheap, and we want to provide only the best quality service possible with no compromises, and our customers appreciate the superior quality. Most of them are running their SEO sites like a business, where they don't mind paying $50/mo if it will help them make $5000/mo.
