It is also very helpful for people who struggle with the English language in general and writing in particular. A free article spinner or paraphrase tool makes it easier for them to get new content with minimal effort. The quality of content created with article rewriter is close to human written content if not equally good. To ensure the quality, you can edit content to fix any errors.
Only standard WordAI spinner showed 12% match for me in Copyscape which is very good I think. Also I will add that for SPAM links in general you don’t need any quality at all. if Google crawler can’t find connection with other spinned articles – goal achieved. Sorry, but I don’t see that with expensive spinners as Copyspace shows that in plain sight.
To rank your website in search engines you have to post content at your website on daily basis. If you have more than 2 websites then it is almost impossible to write unique content on all those websites. To do this task webmasters use article spinning tools so that they can post articles to their domains daily. Paraphrasing Tool is also used by students when they have less time to submit their assignment; they just copy content from the internet, rewrite it, remove grammar mistakes and submit it.
