Youtube is one of the easiest ways to get online exposure to what you do; your portfolio; the interior of your business location; an event and more! The other thing people neglect with youtube videos is the codes can be easily placed on your website, facebook, twitter or blogger and it's a great way to get featured/listed on google search engines when people are searching for a specific business in an area. Of course, your video will popup based on the title of your video, so select your name wisely.
See what pops up when you do a search for your city/business industry and look for youtube videos. Ex. Atlanta Makeup Artist. You'll find both websites and youtube videos popping up in the search. If there aren't any in your business category, I suggest you create some as soon as possible to help you in search engine rankings. Enjoy!
