In shortA click rate under about 0.8% says the ad reached people it did not belong in front of — but the number is a ratio, so it means little under a few thousand impressions, and a rate of exactly zero is a delivery problem rather than this one.
Click-through rate is the cheapest early signal Meta gives you. It arrives long before cost per lead means anything, because clicks accumulate in hours where conversions take days. That makes it the first honest answer to a simple question: did this ad belong in front of these people.
Why 0.8%
It is set low on purpose. Click rates vary enormously by placement, format and industry, and a threshold tuned to a good average would flag most of a healthy account. At 0.8% the rule is not claiming the ad is underperforming its category — it is claiming that fewer than one person in a hundred and twenty found it interesting enough to touch, which is hard to defend whatever the category.
A ratio needs a denominator
0.6% sounds precise and, on three hundred impressions, describes the difference between two clicks and three. Nothing about that is a finding. This is the reason confidence here is tied almost entirely to impression volume rather than to how far below the line the rate sits.
Past five thousand impressions the rate stops jumping around and starts describing something real, and the card says so. Below a thousand it is still shown — suppressing it would hide a genuinely broken ad for a day — but it is shown with the low confidence it has earned.
A percentage with no denominator beside it is not a measurement. It is a rounding of something very small.
Why exactly zero does not fire this
Zero is not the bottom of this scale. It is usually a different fault entirely: an ad that never delivered, a placement that renders nothing, a link that fails before a click can register. Folding those into a creative finding would send you to rewrite a headline when the ad was never shown to anybody.
So the rule requires a rate above zero. What looks like a missing edge case is the rule declining to answer a question it cannot see.
What to change
The proposal is to tighten the audience and test a different angle, and it is marked medium risk rather than low for a reason worth understanding. Narrowing an audience is not automatically an improvement — an audience too small to deliver against produces no clicks at all, which is the finding above this one.
- Check frequency first. Above three, treat it as fatigue instead — the fixes point in opposite directions.
- Check placement. A rate dragged down by one surface is a placement decision, not a creative one.
- Change the angle, not the wording. A rate this low is rarely repaired by a better headline for the same idea.
- Keep the audience wide enough to deliver. Tightening below what delivery needs trades a low click rate for no clicks.
When Admetriq raises it
The actual rule, so you can hold this page against what you see rather than take its word for it.
- Fires when click-through falls below 0.8% (CTR_LOW = 0.8).
- It also requires the rate to be above zero. Exactly zero is excluded deliberately: no clicks at all on a delivering ad is a different problem, and no clicks because nothing was delivered is a different finding again.
- Confidence starts at 0.5 and gains 0.15 once the ad has at least 5,000 impressions, where the rate is stable enough to trust. Under 1,000 impressions the confidence drops instead.
- The proposal is an audience refinement — tighten who it reaches and test a different angle — carried at medium risk rather than low, because narrowing an audience can starve delivery as easily as it can sharpen it.

Frequency separates them. A low click rate at a frequency near one means the ad never landed, on people seeing it for the first time. The same rate at a frequency above three means it landed once and has been shown to the same people until they stopped noticing. The first is a targeting and creative problem; the second is an audience-size problem, and they have opposite fixes.
