Reading Ad Results: Metrics That Matter

Ads produce data and data tells you what to do next this lesson gives you a clear framework for reading your numbers and translating them into specific actions

The Metrics Dashboard: What Actually Matters

CPM: Cost Per 1,000 Impressions

What it tells you: how expensive it is to reach 1,000 people with your ad.

Benchmarks for Meta in the UK in 2026 for service businesses: under £8 is unusually cheap and signals good audience or high relevance. £8 to £15 is the normal range for most service businesses. £15 to £25 indicates a competitive audience or broad targeting. Over £25 means the audience is very competitive or targeting is too narrow.

What affects CPM: audience size where broader means cheaper CPM, competition where more advertisers in your niche means higher CPM, ad quality where more engaging ads means lower CPM, and time of year where Q4 is always the most expensive.

What to do: if CPM is very high and results are poor try broadening the audience first. If CPM is normal and results are still poor then CPM is not the problem.

CTR: Click-Through Rate

What it tells you: what percentage of people who saw the ad clicked it. This is the primary indicator of creative quality.

CTR equals clicks divided by impressions multiplied by 100.

Benchmarks for Meta link clicks: under 0.5% means the hook or creative is not stopping the scroll and you should test a new hook. 0.5 to 1% is below average and something is working but not well. 1 to 2% is average for most service businesses. 2 to 3% is good and the hook is landing. 3% and above is strong and this creative angle is resonating.

What low CTR means: the hook is not relevant to this audience, the creative image or video is not stopping the scroll, or the targeting is reaching the wrong people.

What high CTR with high CPL means: people are interested but the landing page is not converting so the offer, form, or page copy needs work.

CPC: Cost Per Click

CPC equals ad spend divided by clicks.

Benchmarks for Meta in the UK in 2026: £0.50 to £3.00 for most service businesses.

CPC is a derived metric that goes down when CTR goes up. A great hook on the same budget produces more clicks and lower CPC automatically. Optimise for CTR and CPC follows.

CPL: Cost Per Lead

CPL equals ad spend divided by number of leads which are form submissions.

This is the metric that matters most for service businesses.

How to interpret CPL: compare it to your ceiling which is 10% of average project value from the first lesson. If CPL is under your ceiling the campaign is worth continuing and scaling. If CPL is 1 to 2x your ceiling improve the landing page before scaling. If CPL is 3x or more your ceiling something fundamental is wrong with the hook, audience, or offer.

Lead Quality: What the Numbers Do Not Tell You

CPL tells you what leads cost. It does not tell you if they are good leads.

Track separately outside your ad dashboard: how many leads from ads booked a discovery call, how many calls converted to proposals, and how many proposals converted to projects.

If your CPL is £25 and 20% of leads become clients with an average project of £1,400 your effective cost per client is £125. That is an 11x return on spend. The ads are working even if £25 per lead felt expensive before you calculated the full number.

The Weekly Review Routine: 15 Minutes Every Monday

Step 1: Check four numbers (3 minutes)

CPM to check if reach is getting more or less expensive. CTR to check if the creative is still performing or fatigued. CPL to check if leads are getting cheaper or more expensive. And lead volume to see how many total leads this week versus last week.

Step 2: Check lead quality (5 minutes)

How many discovery calls booked from last week's leads? Are there any patterns in who is responding?

Step 3: Make one decision (2 minutes)

Kill a loser with CTR below 0.5% or CPL 3x or more above your ceiling after 7 or more days and £50 or more spend. Scale a winner with a profitable CPL, 5 or more conversions, and 7 or more days running. Or test one new variable.

Step 4: Update ADS.md (5 minutes)

The Claude Weekly Review Prompt

Using @ADS.md — run my weekly ad review.

This week's data:

- Campaign: [NAME]

• Total spend: £[X]
• Impressions: [X]
• Clicks: [X]
• Leads: [X]
• CPM: £[X]
• CTR: [%]
• CPC: £[X]
• CPL: £[X]
• Lead quality notes: [X calls booked / X qualified / X unqualified from

last week]

My CPL ceiling from ADS.md: £[X]

Tell me:

1. What the data is telling me about each of the four metrics
2. Which ad to pause, which to scale, which to leave running
3. The one change that would most improve results this week
4. New hook or copy variations to test based on what is working
5. The update to add to my ADS.md campaign log

Ad Fatigue: When to Refresh

Ad creative has a lifespan. On Meta high-frequency campaigns where the same person sees the ad multiple times experience creative fatigue and CTR drops, CPL rises, and results deteriorate.

Signs of fatigue: CTR dropping week-over-week despite no changes, CPL rising week-over-week despite no changes, and frequency which is the average number of times each person has seen the ad going above 3 to 4.

When you see fatigue introduce new creative and not a new campaign. Keep the same hook angle if it was working and use a fresh image or different video. The message is still good and the face of it needs to change.
