How to advertise a yoga class
Consider the different methods of advertising and how each one might fit into your budget and time availability.
Begin with the least expensive yoga class advertising tactics, such as getting the word out through social networking communities. Updating your social networking presence by announcing class logistics won't cost money but it will take time.
Conclude your advertising methods assessment by ending with the most expensive options, such as direct mail campaigns to people living in the area. Although handing your yoga advertising campaign to a marketing agency can cost thousands of dollars, your time investment will be significantly less.
