The most common way for people to find products or services online is to use search engines, especially Google, Bing or Yahoo. These search engines have certain criteria for giving websites more (or less) opportunity to be returned in search results. The way to obtain dependable, long term search engine optimization is to post as much quality content to your website as possible. The more unique readable text your site contains, the more logical area search engines will have to index and thus refer people to your site. More quality content means more opportunities for your website or blog to receive traffic from major search engines.
And then there is the amount of time that it takes to create content with this software. I have had past experience with text spinners and although it might seem like a fast way to write content, it often isn’t! By the time you have chosen a piece of content (or multiple pieces of content to blend together), put it in the software and produced content with this software, you could instead have created content that Google loves.
