I do mobile detailing and two weeks ago I canvassed neighborhoods with flyers putting them under peoples doormats. 500 total flyers put out and 2 days worth of my time, not a single call or text came. I’m feeling disappointed knowing that these probably all ended up in a landfill somewhere. Any advice? Where’d I go wrong?

Edit: I don’t have a picture of said flyer but it was pretty straight forward. In bold “Mobile Detailing”, my number, google page link and a special offer for that specific neighborhood.
