How do you set an ad budget? Meta and Google for small businesses

In short: Set your ad budget by goal, not by guesswork: work out what a customer earns you and how much you can pay for a lead, start with a small test budget and increase it based on measured results. Being able to measure which ad actually brings customers matters as much as the budget itself.

First, define the goal

"Being more visible" is not a goal. Write down in one sentence what you want the ads to bring:

• Quote form submissions
• Bookings or calls
• Online sales
• Customers walking into your shop

Without a clear goal, there is no way to tell whether the budget is working.

What does a customer earn you?

The soundest way to set a budget is to work backwards:

1. What is your average sale or job value?
2. How much profit is left from that sale?
3. How many leads turn into customers? For example, if two out of every ten quotes become sales, your conversion rate is twenty percent.

With these three figures you can calculate the most you can pay for a lead. As long as the ad’s cost per lead stays below that figure, the ads are profitable.

Start with a test budget

In the first month the goal is not big sales but learning. With a small budget:

• Try different visuals and copy.
• Compare different audiences.
• Measure which ad brings leads.

As the combination that works emerges, shift the budget towards those ads and increase it gradually. Starting with a large budget straight away means spending without learning.

Google or Meta?

• Google Ads reach people who are already searching for you: someone searching for "web design company in Istanbul" already has the need. Purchase intent is high.
• Meta ads (Instagram and Facebook) reach people who aren’t searching yet but may be interested in your product. They are strong for visual products, new brands and campaigns.

For most businesses the two work best together: Meta creates demand, Google captures the demand that exists.

Don’t advertise without measuring

The clicks and impressions in the ad dashboard say little on their own. Without conversion tracking on your site and forms, you can’t know which ad brings customers. What needs to be set up:

• Tracking of conversions such as form submissions, calls and sales
• Tags that show which campaign a visitor from an ad came from
• Collecting incoming leads in one place (a panel, a CRM, or at least a well-kept spreadsheet)

Common mistakes

• Sending ads to the home page: a landing page that takes visitors straight to what the ad promised converts much better.
• Visuals that never change: an audience that sees the same ad for months gets tired of it, and costs rise.
• Deciding in the first week: platforms have a learning phase; decide once enough data has been collected.
• Putting the whole budget into one campaign: spread your risk so you can compare.

Conclusion

The right budget is set by your business’s profit structure and measured results; industry averages only give you a starting point. If you want to set up your campaign around a goal and manage it by measuring the results, take a look at our advertising and customer acquisition service.
