sorry i could not find a good title. we know that, google thinks that a page has high quality if the visiters stay in the page a lot.i think google understand it by the toolbar or firefox. visiters stay a lot in pages that contains video(they are watching the video). and i think that is very good for the page.when i search on google, i always see a video page in top 10.they are inner pages, has no backlinks but they are in top 10. i started to use videos on my homepages. do you think it can be useful and my thought can be right?
