While it does cost actual money one of the cheapest advertising things you can do is to buy a domain name like PTmowTech then use that as your sign in on forums like this.
My business name is Berts Mobile Mower Repairs thus on all mower & small engines sites my screen name is Bertsmobile .
This sort of identifies you as a business to other users.
As for Face Ache buy a really cheap old laptop and use that to set up another Gmail & Face book account.
Face ache use the MAC number as the primary identification so their server knows it is your computer it has connected to.
Then it looks for the cookie or keys that it installs to verify the account once you have set it up .
This stops people who have been banned from opening a new account using a false identity
And I use a false identity so to most groups I am a 101 year old man who lives in a nursing home and is a pensioner .
Thus your account gets tossed into the "No Commercial Potential " and by & large you get almost no spam as you are well & truely outside the parrameters of the advertisers .
Because I do not want to be the next Musk or Besos I have found the best advertising is to give the local primary schools , church groups & charities service vouchers for them to use to raise funds with.
When I was selling refurbished mowers I used to go to the local car boot sale run by a church which costs $ 20 .Usually I could shift at least 3 walk behinds .
Plus a stack of stickers for people to take home ( much better than a business card ) and some flyers to hand out .
I also took a lot of blade carriers with new blades installed ( we use swing back blades ) and they sold like hotcakes .
Even better is most who bought them have become parts customers so I can buy bulk blades and sell them at a 300% mark up while still being cheaper than big box stores.
When I have some spare time ( or it is raining too hard ), I make them up so I can always do an exchange, only $ 10 gross mark up but it means I can buy bulk blades so all of the blade replacements make better mark ups .
