Rule template: pause ads when the cost per link click is too high
Short answer: pause an ad when its cost per link click over the last three complete days is above the most you can afford to pay for a click, and only once it has enough clicks to judge, for example 30 link clicks. Work the limit out from your own numbers: target cost per result × click-to-result conversion rate = the highest CPC you can pay.
The template
| Setting | Value |
|---|---|
| Apply to | Ads |
| Condition 1 | CPC (spend ÷ link clicks), last 3 complete days > your CPC limit |
| Condition 2 | Link clicks, last 3 complete days ≥ 30 |
| Join | Both conditions (AND) |
| Action | Pause the ad |
| Notify | Every time the rule pauses something |
Working out the CPC limit
If one result in four clicks is acceptable at $20 per result, a click is worth $5; at one result in fifty clicks, the same $20 target allows $0.40. The formula is the target cost per result multiplied by the share of link clicks that turn into results.
| Target cost per result | Clicks that convert | Highest CPC you can pay |
|---|---|---|
| $8 | 10% | $0.80 |
| $20 | 5% | $1.00 |
| $20 | 2% | $0.40 |
| $50 | 4% | $2.00 |
Read the conversion share from your own data (results ÷ link clicks over the last 30 days), not from an industry average. To leave room for normal day-to-day swings, many buyers set the rule at 1.3–1.5 times the calculated limit; these are worked examples, not advice for a particular offer.
Link clicks or all clicks
Meta reports two prices. CPC (all) divides spend by every click on the ad, including clicks on the Page name, likes and "see more". CPC (cost per link click) counts only the clicks that lead to your destination. When you pay for visits to a landing page, the link-click price is the one to limit.
Edge cases
- Small samples. Ten clicks can make any ad look expensive or cheap. The click minimum in condition 2 stops the rule from judging too early; raise it for cheap clicks, lower it for expensive ones.
- CPC is not the goal. An ad with expensive clicks can still bring cheap results if those clicks convert well. Pair this rule with a cost-per-result limit, or add "and cost per result above target" to the same rule.
- New ads. Prices jump around in the first days of delivery; see the learning phase.
- Time zones. Complete days end at midnight in the ad account's time zone, not yours.
Setting it up in Meta Ads Manager
- Open Rules in Ads Manager and create a new rule.
- Apply it to your active ads and choose the action to turn ads off.
- Add the condition CPC (cost per link click) is greater than your limit, plus a minimum for the sample: link clicks or impressions greater than your threshold.
- Choose a three-day time range and a daily or continuous schedule.
- Turn on notifications and save.
A rule in Meta belongs to one ad account. With twenty ad accounts, it is twenty rules to create and keep in sync.
Setting it up once for all ad accounts in Multitool ADS
- One rule covers every ad account in the workspace.
- CPC is a condition on spend divided by link clicks or by all clicks, with the click minimum in the same rule.
- Windows: today, yesterday or the last 3, 7, 14 or 30 complete days, each in the ad account's own time zone.
- Scope by country and by campaign, ad set or ad name.
- Data that is not fresh is never judged as zero.
- An ad paused by the rule is switched back on automatically within an hour if the condition no longer holds, and every pause comes with a Telegram notification.
