So I have this nice website coasting along in position 8 for a couple of good search terms. I create two short and good class videos to give it more respectability then a week later the site drops to no.10 for both terms. Coincidence? Maybe. I'm reluctant to remove the videos now because we know how paranoid G can become if a site is altered too much in an attempt to affect search positioning. So; has anyone had experience of this? I appreciate that the videos will have increased loading time and perhaps this is a factor in the lower positioning.
