Running Meta ads can sometimes feel a bit like throwing spaghetti at the wall and hoping something sticks.
One day the results look brilliant. The next day your cost per lead has doubled and you’re suddenly questioning every marketing decision you’ve ever made.
The problem is that a lot of businesses are looking at the wrong numbers.
Or worse, they’re staring at Ads Manager wondering what half the jargon actually means.
So here’s a simple breakdown of the key Meta ad metrics worth paying attention to, how to spot when something isn’t working and what to do next.
CTR (Click Through Rate)
What is it?
CTR shows the percentage of people who clicked on your ad after seeing it.
In simple terms:
Are people interested enough to actually click?
A good sign:
A healthy CTR usually means your creative, messaging or offer is resonating with the right audience.
Warning signs:
If your CTR is low, it often means:
• your creative isn’t catching attention
• the messaging isn’t clear
• the audience targeting is off
• or the ad simply isn’t interesting enough
What to do:
Before changing your audience, test new creatives first. Often the issue is the content itself, not the targeting.
CPC (Cost Per Click)
What is it?
This is how much you’re paying every time someone clicks your ad.
Warning signs:
If your CPC starts climbing, Meta is usually finding it harder to get engagement from your audience.
This can happen when:
• audiences become fatigued
• ads have been running too long
• creative stops performing
• competition increases
What to do:
Refresh creatives regularly. Sometimes even changing the first line of copy or swapping the image can improve performance.
CPM (Cost Per 1,000 Impressions)
What is it?
CPM tells you how much it costs to show your ad to 1,000 people.
Important thing to know:
A high CPM doesn’t automatically mean your campaign is failing.
Seasonality, competition and audience size all affect this.
For example, ad costs often rise significantly around major retail periods and holidays.
When to worry:
If your CPM is high AND your CTR is poor, it usually suggests the audience isn’t responding well to the ad.
Frequency
What is it?
Frequency shows how many times the average person has seen your ad.
Warning signs:
If people keep seeing the same ad repeatedly, performance usually starts dropping.
This is called ad fatigue.
You’ll often notice:
• engagement dropping
• clicks slowing down
• CPC increasing
What to do:
Rotate creatives before audiences get bored. Even strong campaigns need refreshing.
Conversion Rate
What is it?
This measures how many people completed the action you actually wanted after clicking.
For example:
• making a booking
• submitting an enquiry
• downloading a brochure
• purchasing a product
Important thing to remember:
Sometimes the ad isn’t the problem.
If people are clicking but not converting, the issue might actually be:
• the landing page
• the website experience
• unclear messaging
• slow loading times
• confusing booking journeys
This is why looking at ads in isolation rarely tells the full story.
ROAS (Return On Ad Spend)
What is it?
ROAS measures how much revenue your ads generated compared to what you spent.
For example:
Spend £1,000 → Generate £4,000 revenue = 4x ROAS.
The mistake businesses make:
ROAS should never be looked at without context.
A campaign with a lower ROAS might still be valuable if it’s building awareness, growing remarketing audiences or supporting long term sales.
The Biggest Mistake? Changing Things Too Quickly
One of the most common issues we see is businesses panic editing campaigns after a couple of days.
Changing:
• audiences
• budgets
• copy
• creatives
• objectives
…before Meta has had enough time to properly optimise.
Sometimes campaigns need breathing room before performance stabilises.
Constantly tweaking campaigns can actually make performance worse.
