I think holidays are one of the easiest ways to advertise. Candy bags or mugs with candy given out for free with business card. These days free stuff for people, is a nice thing. Also if you give them out by hand with smile, shows how much more you care.
I know an agent, she does Easter egg for kids. She does it in her farming area. I think that is fun and great for kids in the neighborhood. Also gets you involved with the community. So like I said holidays for it.
It’s a good way to get exposure. Holidays give you themes and easy ways to plan how to advertise yourself around that time.
