Meta Ads on a small budget: what $100–200 a week really buys

You can run Meta ads on $100–200 CAD a week. You cannot run five campaigns on it. Most small budgets fail for one reason: they are spread so thin that the system never learns who to show the ad to. Here is what that money realistically buys, and how to not waste it.

How the auction actually decides

You are not buying impressions at a fixed price. Every time someone opens Instagram, Meta runs an auction among advertisers who want that person’s attention, and it favours the ad most likely to get a result. That means a better ad costs you less per result than a mediocre ad with a bigger budget.

This is good news if you are small. You cannot outspend a national brand, but you can outperform them on relevance in your own neighbourhood.

The learning phase, and why small budgets stall

Every new campaign starts in a learning phase. Meta needs roughly 50 results in a week for one ad set before its delivery stabilises. Below that, it keeps guessing and your cost per result stays high and erratic.

Now do the arithmetic. If a message conversation costs you around $4, fifty of them is $200 — one week of a modest budget. That works, but only if all of it goes to one ad set. Split $200 across five ad sets and each gets $40, none reaches the threshold, and all five stay expensive forever.

What $100–200 a week actually buys

Honest ranges for a local service business in the Montreal area, once the campaign is past learning:

• Reach: roughly 8,000–25,000 people per week, depending on how narrow your area is.
• Direct message conversations: roughly 15–40 per month.
• Clients from those conversations: depends entirely on how fast you answer. Replying within an hour can double what the same ad spend produces.

For context: our own client B. Martinez Multiservices got about twenty direct-message leads in the first month from a single campaign. Not from a bigger budget — from one clear message and a fast reply.

Creative beats targeting

Advertisers obsess over audience settings and ignore the ad itself. It is backwards. Meta’s algorithm finds your buyers better than your guesses do, as long as you give it a broad-enough audience and something worth stopping for.

What works at small budgets:

• Video shot on a phone beats a polished graphic more often than agencies admit. Real hands doing real work.
• One message per ad. If the viewer has to read twice, they scroll.
• The first three seconds carry everything. Lead with the problem, not your company name.
• An obvious next step. “Send us a message” outperforms “Learn more” for local services, because it matches what the person is actually ready to do.

What to measure, and what to ignore

Ignore likes, reach and “engagement”. They do not pay anyone. Track two numbers:

• Cost per conversation (or per lead). This tells you whether the ad works.
• Cost per client. Conversations divided by how many became clients, multiplied by cost per conversation. This tells you whether the business works.

If a client is worth $500 to you and costs $60 in ads to acquire, keep going and spend more. If they cost $400, the problem is rarely the ad — it is the offer or the follow-up.

When not to run ads at all

We tell clients to wait when:

• Nobody answers messages within a few hours. Paid attention has a short shelf life.
• There is no clear offer, only “we do everything”.
• The profile or website the ad points to looks unfinished. Ads amplify what exists; if what exists is not convincing, you are paying to show it to more people.
• The budget is under about $50 a week. At that level you are paying for data you cannot act on.

What it costs to have it managed

Two numbers people confuse. Your ad spend goes directly to Meta — you pay Meta, not your agency. The management fee pays for the strategy, creative, targeting and weekly optimization. At REYS that fee is $175 CAD per campaign per month, and we recommend $100–200 CAD per week of ad spend alongside it.

If anyone quotes you one lump sum without separating those, ask which part is going to Meta. You should always know.

Start with one honest question

Before spending a dollar: if fifteen people messaged you tomorrow, could you answer all of them the same day? If yes, ads are a good investment. If no, fix that first — it is free, and it doubles the return of everything that follows.
