Ok, what is link rel=canonical and how exactly can I use it? If I copy pasted some ads per say on my website from CL, lets say in the beginning to populate my site(I dont even have one yet), aside the legal issue, will Google instantly pick up on it and de-index me? Also, I am now aware that Meta Keywords and Description hardly affect search results. Just how could I for example, have google return a search result for "New York cars" to my site? What does it take to strengthen the websites ability to be at the top results?
