I thought i was going good. I got to the top of page 2 for a 500k competition boobs related kw but then it disappeared after a week or so . I am not sure what caused it. I had been using vagex to gain views and it was going strong for that week. i put 20k on it and let them run. once they ran out i left it for a few days to see if was gonna go up on its own before adding more. i waited and it didnt move so i put another 20k views in and thats when it disappeared form ranks . Now it could have just have been coincidence and its totally unrelated but i dont know either way really. Im thinking it might be because of the sharp decline then sharp increase flagged it to be mechanical and gave me a penalty but im just guessing. i was also building backlinks with gsa but i was building only good ones this time, contextuals and the like as i got another video banned recently i suspect from using the spam stuff- that one was over 3 motnhs old or so and so couldnt have been the same reason as this cos i wasnt building any more vagex views on that and the only change i made was adding backlinks. any ideas what might have happened and how to prevent in future?
