Rewriting your article by hand is the classic approach that is slowly dissolving, however, many people still prefer so. Write manually and then rephrasing to ensure the finest quality is the safest way but it can often hours, days or weeks to finish a writing task that can otherwise take only a little time. And that’s why there also exist people who like to save the trouble and their time, so they look for an article rewriter or article spinner to do the job.
Spin Rewriter 5.0 technology was a previous edition that allowed their clients to use the basic article rewriting system. Their newer versions over the years have just kept getting better and better. The new Spin Rewriter 9.0 technology gives you the option of assigning variables to your content. Their software is dead easy to use. In just three steps you can have up to 50 uniquely spun articles.
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.
