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.
For this purpose, humans have created numerous rewriting tools to save time and use all words available in the English dictionary. Rewriting tools use millions of synonyms made available to them through artificial intelligence and instructions given by the human mind. If you hire the services of a content writer to rewrite/create content for you, they will charge you a lot. Big organizations can afford this but small startups and students can never afford the services of professional writers.
Quality readable content is key here. Google, for example, will recognize that people are leaving your site soon after arriving if they perceive that your site or blog is full of junk content. This is called "bounce rate." If your bounce rate is high, then people are quickly leaving your site. But for the sake of your business, to build your online reputation and brand, you want people to visit your site, stay for a while, and then keep revisiting over the long term.
