Small business advertising: what each channel costs

Every post on this shelf prices a channel the way an invoice would: what it costs to start, what it costs to actually work, and what it sent, with a date on every number. Meta, Nextdoor, TikTok, the push networks, the directories that charge for a featured slot. Read the cost tables first, then the failure modes, because the cheap channel is usually the one with a floor nobody printed on the sign-up page.
