I would like to mention about Optimizing your videos that you publish in youtube.com,veoh.com,metacafe etc!!These videos you use are for marketing your site/landing pages or some product.To get the most out of these videos you should make sure to optimize them properly.That will result in targeted visitors to your site and that may convert well.. So make sure to add good title for your videos,that plays the major role in getting listed in the search.Make sure to add a description that has some reasonable amount of keywords about your site.This is another important thing that you should not forget.But always make the description relevant to the videos.Tags-->these play a major role in getting listed for your keywords.So do some keyword research and get some good tags that are very well relevant and use them!! I am sure these tips will help to rank your videos well.....Though they are simple tips I believe they play very important role in getting traffic.If you guys have any more tips on optimizing your videos please share!!
