I just got report for one "popular" diversity service,I bought biggest package for around 100$. When I was starting to check articles on them,I got that most of them are only about 40% unique. Seller provided me with 4 spinned articles,and to make things more unique I gave him 4 handwritten articles as well (they were never used before). Number of links he provided in tier 1 are about 150. Now he is telling me that that is ok,and that it is more important for article to be readable then unique. Which is just not true in my opinion. Links are made only for google to see them,and for diversity.Not for traffic. Probably there won't be people who will read them anyway. Yea,they should give a little bit power to website,but that is my my priority. But when I compare two articles they are about 40% to 62% similar. So because there were 8 articles,there are 20 articles that are this much similar. (From each article 20 of spinned were created). I won't tell which service for now,but I want to know opinions from people who know SEO, I know there are a lot of people who are still learning here,but I really want to confirm from people who are doing SEO for a year or more. Please post your opinion. Will these links and articles hurt my website or will they help?Or none from those two? Did I just waisted 100$? Is it more imporant for article to be unique or readable?
