Given that penguin updates are likely to remain every 4-6 months or so for the forseeable future, I'm considering the possibility of creating disposable ecommerce sites to rank quickly, accepting the fact that they are likely to get bombed on the next penguin update. Basically what I'm looking to do is to launch a site, then immediately after a penguin update throw a ton of poor quality links at it. This will hopefully lead to good rankings for a short period, before the site gets penalised on the next penguin update. I know there are flaws in this plan, but its something I want to try. Has anyone else done this? What were your findings?
