We hear this question every week: “I only have a small amount — should I run an ad or not?” The answer: yes, as long as you spend it right. A small, well-aimed budget gets better results than a large, scattered one.

The amounts here are in US dollars to keep things simple. Convert them to your own currency; the principle is the same anywhere.

Rule one: know what your ad is for

Before you spend a single dollar, ask yourself what you want from this ad:

  • WhatsApp messages: the best goal for most local shops
  • Page visits: to build a new audience
  • Engagement and mentions: for an offer or an opening

Pick one goal per ad. Mixed goals waste money.

Rule two: narrow targeting beats broad

A common mistake: targeting “your whole city and the whole country”. Your shop sits in a specific neighbourhood. Your audience lives within 5–10 km of you and has interests related to what you sell. Tight targeting makes $40 work like $150.

Rule three: measure inquiries, not likes

A like on a post is not a customer. The only thing that pays the rent is inquiries and messages. Before you stop an ad, ask:

  1. How many new messages did the ad bring in?
  2. What did each message cost? (budget ÷ number of messages)
  3. Are these customers who could come back?

There’s no single “good” cost per message: it varies a lot from country to country and from one business to another. The real test is whether your cost per message goes down from one month to the next.

A sample week: $10 of your $40
