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.
If you consider that you can spin articles with Search Engine Optimization (SEO) in mind it definitely makes Spin Rewriter 9.0 worth the money. Your articles will now be able to rank in Google for your keywords you want to rank for. The more content you can produce and put on your website the quicker Google will rank you. This allows you to quickly create scalable evergreen content that will rank for years.
4. Tier 2 content (content that is keyword rich and relevant to your niche. Doesn’t have to be all that readable, it just has to be indexable by a search engine.)– Here put same options as with the Tier 1 content situation with the only difference that you set the 1st input to “Regular.” It is important that lower tiers have a lower quality of content compared to upper tiers.
