So I am in the process of trying to rank number 1 in Big G for a few keywords for one of my churn and burn sites before a product launch next week. On page SEO seems good and so far I have paid traffic in the form of drip fed social bookmarks and PBN comments/links, GSA blast and most recently since its only a week to go some SAPE links. As a result of this I was ranking number 8 for one of my main keywords and number 14 for another. However just yesterday it seems a reasonably big review site has ranked instantly and out of nowhere for the first 2 or 3 positions and pushed me in to the second page! Can anyone here help or give some advice on how I could beat these guys to number 1? Could I possibly wait until a few days before the product launch and blast some more PBN Links towards my site? Thanks in Advance.
