For the past few days i have been optimizing a particular page and was ranking on the 5-6 position for it. The page is pointing to another website that has a movie on it. This afternoon when i uploaded a video on youtubbe pointing to the website, i got chucked from the serps. Right now my site is on position 700. Besides uploading the video i did nothing else and i don't know why google has done this. I just sent out a reconsideration request. Hope i can get back on track.
