You can still find some grammar mistakes in the paraphrased article, but its only minimal and the resulting article is still highly readable and the uniqueness is relatively high, though I was not able to check the article rephrase in a plagiarism checker like Copyscape, although based from the result, I believe it can be used perfectly for tier 2 and tier 3 link building campaigns
Subscribing to an article spinner like Spin Rewriter 6.0 certainly isn't the cheapest option around, but compared to having to pay around $5 to $10 an article. The article spinner route is certainly much less expensive especially if you want around 50 to 100 pages of content for your website. The cost can run into the thousands and the less than $100 per year cost of Spin Rewriter 6.0 begins to seem extremely reasonable.
The more synonyms and phrase relations there are in it, the more the spinner will understand whatever content is thrown at it and the better the content it produces will be. Now that’s not specific to Spin Rewriter but I thought I’d throw in this as most people probably have no idea what a spinner does and then complain when a certain word is replaced with the wrong synonym (context-wise).
SEO is important to get readers. But if your writing is to obviously geared towards search engines you will quickly lose readers. When you write for a keyword phrase, you need to use the phrase enough so that it's recognized as the topic but not so much that your readers notice. If you have the same phrase repeated in a sentence, that's too much. More than twice in a paragraph is too much.
When you integrate Perfect Tense with Spin Rewriter, Perfect Tense will check your seed article for grammatical mistakes before Spin Rewriter spins it. With higher quality seed articles, Spin Rewriter will be able to create higher quality content. In many instances, these improvements will lead to spun content that is higher quality than the original.
