Thank you for creating this thread, OP. Now I have one question less. But I still have some. One of the unexplained questions for me is off page SEO. I have a site and one of my friends analyzed it with some fancy SEO tools. He told me that I should buy links and even told me that this https://crowdo.net company can make a lot of quality links for me. Now I think - do I really need this? It's not like the prices are bad or I don't trust my friend, but - money is money. I don't want to spend it.
