8 common mistakes when launching Meta Ads campaigns (and how to avoid them)

Meta Ads (Facebook and Instagram) can work very well, but it can also easily spend budget with no results. These are the mistakes we see most.

1. Launching without measuring properly

Starting to spend without the pixel, the Conversions API and the key events installed. Without data, the algorithm does not learn and you do not know what works. Measurement first, budget second.

2. Choosing the wrong objective

Optimising for clicks or visits when what you want is purchases or requests. Meta brings the people who do what you ask: if you ask for clicks, it brings people who click. Choose the objective closest to the business for which you have enough data to optimise.

3. Splitting a small budget across many campaigns

With small budgets, it is better to have a few well-fed campaigns than many ad sets with crumbs. Each ad set needs a minimum volume of conversions to leave the learning phase.

4. Changing the campaign every day

Modifying budgets, audiences or ads every day resets learning. Let it run for a few days, look at trends and make one change at a time.

5. Generic creatives

A catalogue image does not stop the thumb from scrolling. Test different formats (photo, short video, carousel), clear messages and concrete benefits. Take care of the vertical format for stories and reels.

6. Sending traffic to a website that is not ready

This is the costliest mistake. If the ad works but the website:

• Is slow in the Facebook or Instagram in-app browser,
• Covers the screen with a huge cookie banner on mobile,
• Has a long or confusing checkout,

you lose visitors before they see anything. In one of our shops we observed that roughly a third of ad visitors left in under ten seconds, and that the cookie notice took up almost half the screen on mobile. Fixing it costs far less than raising the budget.

7. Ignoring remarketing

Someone who visited your site and did not buy is the cheapest audience to convert. Create campaigns for those who saw products, added to the cart or reached checkout, excluding buyers.

8. Not looking at the real data

The platform credits results to itself. Always check against your shop or CRM: real sales, revenue and margin. A campaign with a good ROAS in the dashboard may not be profitable in your till.

A simple method to start

1. Define the objective and the maximum CPA you can pay.
2. Install and test the pixel and the Conversions API.
3. Prepare the website: speed, clarity and checkout.
4. Launch one campaign per objective, with 2 or 3 different ads.
5. Wait, measure and optimise with small changes.
6. Scale what works and pause what does not.
