My video listing showed up on Google's first page and then it disappeared? Can you tell me why?

Do not worry! This is part of the normal process for any video that goes up on the internet. As part of the video optimization process, your listing is in a state of flux. This is referred to on Google's search engine as the "Google Dance".This is due to the screening process that search engines such as Google and others use to validate your video listing as a viable addition to the local directory and to ensure that it's not "spam" or in violation of any of the terms of use. You will, without a doubt, see your listing rise and fall off the first page, as this process continues. Once the search engines have gone through the normal processes things will settle down and your video listing should be pretty secure. This might take time but will be well worth it for you in the end.
