There are many ways to market your business – some will cost you some money and others do not. I think a good approach is a mixture of methods, both free and paid.
Following are some free methods you can use to market your business:
Create a free blog here: http://www.blogspot.com
Create free Squidoo lenses here (and link them your blog, and vice versa!)
Create Youtube videos that link to your blog: http://www.youtube.com
Create a FaceBook group (that links to all of the above!): http://www.facebook.com
Whenever you update your blog, lenses, add articles or videos (which should be frequently!), link to them from Twitter: http://www.twitter.com
Give away free traffic positions in this rotator while generating free leads for yourself: 10YearsOfTraffic.com
Total Cost: FREE!
