I know you see where this is going.
If you are marketing yourself or your business, get on YouTube, now! You're already a few years late (like me) but no one is judging you. You'll still be ahead of the game if you hop on now.
"But I'm a hairstylist (or lawyer, designer, restaurant owner, etc.), what could I post on YouTube?"
If you're a hairstylist, make videos about how to do a certain hairstyle at home or how to care for your hair. Include your web address (you do have a sleek and amazing website design don't you?) in your video and voila!
If you're a lawyer, give free tips or talk about uncommon laws.
If you're an author, give writing tips, read part of your book or make a book trailer (which is like a movie trailer, but better).
If you own a restaurant, post quick and easy recipes online.
Just remember to name your video something useful like "Your Topic by Your Name" or "Your Name: Your Topic" (ex: Love & Change Studios: How to Get More Web Traffic on Your Blog) and include your web address somewhere in the video (text and/or verbally).
"But, I don't have a High Def camcorder."
Get over it. They don't have to be Hollywood quality. Just add some good content (or "nuggets" as I like to call them) and your charming personality.
If you want more ideas on types of videos you can post, then tweet me and I will respond with some!
