What Marketing Actually Works for Outdoor Service Businesses During Slow Seasons?

I run a small land clearing/brush clearing business in Ohio, and with how wet it’s been in our area lately, things are starting to slow down a bit. I’m trying to be proactive and focus on marketing so I can keep work coming in and continue growing the business.

For those of you who’ve been in a similar spot, what marketing has actually worked best for you to bring in more customers and keep jobs lined up? Facebook ads, Google ads, yard signs, referrals, local networking, something else?

I’d especially love to hear what’s worked well for seasonal or outdoor service businesses when weather starts affecting the schedule. Appreciate any advice or ideas you’re willing to share.
