Think of it this way: What do you have more chance of hitting, a distant, tiny target or the broad side of a barn? For the sake of search engine optimization, you want your website to be the broad side of barn. The more quality articles, or unique readable content, your website or blog offers to search engines (and therefore the general public) the more exposure your website will receive from major search engines.
While these recommendations give you some general guidelines as to what settings you want to use in these more popular situations, don’t be afraid to customize according to your needs. For instance, if your Tier 1 will build only just a few links, you can set the 1st input to “Very Readable” or even “Extremely Readable” as WordAI will still produce unique content even if only a few versions.
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?!?!
