Is this a serious question? You advertise. Just like people have been doing for generations. You advertise in publications or spaces that will attract people interested in your product or service. You're going to have to do more to convince me that we need individual level targeted for businesses to succeed.
We're not mad if the new bakery in town advertises in the town paper or sends postcards to everyone in the zipcode. We're not mad if the new geeky t-shirt website puts ads on geeky subreddits or Facebook groups. We're not mad if your new auto detailing service comes up if I Google "auto detailing <my city>". We're mad that those ads creepily follow us around the internet, reminding us of the scale of the enormous data collection that enables such behavior.
Don't tell me that bakeries or t-shirt shops or auto detailers can't thrive without targeted marketing. We've had those things for way longer than we've had targeted marketing.
