To see the improvements Spin Rewriter 6.0 has made over its previous versions you should definitely check out the video on their sales website. And if it takes your interest and you are wishing to test out such an article spinning tool to create content for your website. Then there is a 5 day free trial you can take advantage of and will help you decide if it is any use to you and your content creation needs!
Think of it this way: What do you have more chance of hitting, a distant, tiny target or the broad side of a barn? For the sake of search engine optimization, you want your website to be the broad side of barn. The more quality articles, or unique readable content, your website or blog offers to search engines (and therefore the general public) the more exposure your website will receive from major search engines.
Spin Rewriter integrates with almost any SEO software. This allows you to post high quality articles quickly and easily. The only drawback is that you only get something like 300 API requests every 24 hours. You can quickly burn through this if you’re doing multiple campaigns. The developer does not currently offer a plan for heavy API users but maybe they will in the future.
