I am getting ready to purchase a new domain for the purpose of creating an authority niche site with Adsense. Adsense will be the first and probably primary source of income as the niche does not have associated clickbank or amazon products. Perhaps once I have REAL traffic and viewership I can ask for direct banner advertising from companies who sell the products I am giving information for. So with a new domain and only a few pages to it... What are your TOP 5 or less things to do to gain backlinks and favor in the search engines? I am thinking some Fiverr type, inexpensive backlinks that don't do the 10k comment spam links... Maybe small social bookmarking packages? Early on should I do one of those more expensive packages that creates several web 2.0 properties and tons of backlinks to THOSE web 2.0s? What have you done for your new sites?
