i will create hundreds of blogs on expired domains with metrics like DA 10, TF 10 and so on, lets say it takes 2 months to complete this task. Then i find some short time terms such as 'halloween party' which will be searched only from september to november. Then i will set hundreds links from all my pbns within just one week or two. 1. do you think if that will work, or google will set some automatic filter to limit such action? 2. if it works, how long will it take until google cracks down my money site, do you think i can keep my keyword on page 1 for at least 1 or 2 months?
