I want to rank kw's with literally NoCompetition the #1 is an semi authority forum post with 0 backlinks and 5 words of content. Is it a good idea to make a web2.0 for this kw ? I plan to make a wordpress.com blog with one article with around 500-700 words of content and give it 200-500 social signals. Do I need backlinks to rank? Does anyone succeeded in ranking extremely low comp keywords just with a small gsa blast of maybe 1-3k backlinks?
