The simple fact of the matter is that, as an Internet marketer, you need something better than artificial link building and pages of useless, jumbled nonsense to get long-lasting traffic referrals from major search engines such as Google, Bing and Yahoo. Google in particular pays special attention to your visitors' behavior. So if visitors are quickly navigating elsewhere because your site is full of junk content, then you will get fewer traffic referrals from Google over the long run.

It looks like the creators of Spin Rewriter 9 .0 have really put a lot of work into creating a piece of software that creates readable content. However, Google isn’t stupid and there are a lot of things that can go wrong when you are trying to “manipulate” Google into giving you more traffic. Google hates spam, badly written content and duplicate content. These are all things that Spin Rewriter 9 .0 is capable of creating. You simply can’t trust a piece of software to write content for you in my opinion. 

Yea mate, WordAI really is overpriced IMO too, which is why I didn’t rank it higher in the cost-effectiveness rankings. Now, it did change more than a few words, but I see how you would think it’s less than 80% unique. TBS is also great, but only in terms of functionality and the easy interface which allows manual spinning to be done quite fast. As for their thesaurus, I think they have a lot to improve.
In the part of the WordAI processor, the same difficult practice can also make this task quicker by making use of some type of article generator software. This way you will get a large amount of posts within a shorter period. Sometimes, when you are not logged in, the site may claim ownership on your article to bar manipulations from non-human entities.
October 6th, 2018 (Saturday): THE WEEKEND — This weekend will be the perfect time to build more exposure to the offer and really drive the point about the amazing offer home. At this point you should start including countdown timers to the offer close on Tuesday at midnight PDT, describing the pitfalls of not taking action while there's still time, and also describing your own additional bonuses (optional, but great for max conversions).
I wanted to add some phrases in the text to see if the spinner will understand them and possibly replace them with similar phrases. As you see, this is just a simple short story that blew out of my head just a minute ago. As a final note of the intro section, I want you to understand that “thesaurus” simply means a database of words and their synonyms. Let’s see how this goes.
Having a continuous flow of fresh, human-readable text is the best way for your website or blog to gain search engine exposure. Content is King, as they say ... at least as important as basic search engine optimization. Thus, Spinbot can be a vital tool for anyone who wants to market their website or product online as quickly and efficiently as possible. With all the unique, quality textual content you could ever want, you will quickly gain legitimate web visibility, both in terms of human readership and search engine exposure.
After adding the text you intend to process, SpinnerChief lists some basic information about it, such as the number of words, sentences and paragraphs. The 'Select Synonyms' section allows you to choose the terms you want to use, while the 'Quick Sentence Rewriting' and 'Quick Paragraph Rewriting' features enable you to rephrase certain pieces of text.

After rewriting and keeping the dynamics of the writing same, our tool passes it through a plagiarism checker. This ensures that the legal standard of plagiarism is maintained after rewriting the article. After all this process, a final rewritten form is presented to you. All this process may require some time depending upon the nature and length of the article to be rewritten.
There are many people who still prefer rewriting their articles by hand. They are used to write sentence after sentence and rephrase their content to ensure the quality of writing. Although it is the safest approach but it can take hours or days to complete a task. On the other hand, there also exist people who are either too lazy to rewrite their content or they understand the importance of time and hence, they look for an article spinner tool or paraphrasing tool.
Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
