I didn't see this response. To answer your question, each article is dynamic. Some have 15 paragraphs, other have 5, and it's all a mix in between. The article is initially written in subtopics, that can be independent of each other. That way if they are shuffled or removed, the article still makes sense. You can set your first and/or first/last paragraph to be in every article. I choose this, because I can write an intro, as well as a conclusion. In the intro paragraph, I mention the broadest part of the niche that you're writing on. In the conclusion paragraph, I add my link to wherever I want the reader to go. That way, those two are always relevant.
Doing it this way, I have an article, that I've written/rewritten, in about 10 hours of work. I can then go and add it everywhere. To answer your specific of spin words, some are 5, some are 7, some are phrases, some are 20 even! Adjectives are great for spinning articles, so make sure when you have an article, there are descriptive words, such as {good|great|nice|fantastic|wonderful|likable|lovable|etc} and even phrases, or spins within spins. I'm not sure how many levels I can nest, but I've gone as deep as 3... With the normal spinning, you're looking at adding it to tier 2. With THIS way of spinning, you can use it for multiple tiers, INCLUDING your money site itself, if it is appropriate to be there.
I might just have to put together a step by step, with all the tools...
