Compared with typical Meta benchmarks (link CTR around 1%, CPC often €0.40 to €1, a healthy CPM between €5 and €15), this is a strong first campaign. Most of your ads get 2 to 3 times the average link CTR at below-average cost.

Ad by ad:

• Pang, "Maman 47% Papa 12%": your best creative. 3.02% link CTR, €0.23 CPC, €6.84 CPM. Best on every metric, but only 1,489 impressions, so confirm it with more budget.
• Confusion and Hush: the reliable performers. 5,200 and 4,495 impressions at 2.50% and 2.49% link CTR, €0.33 to €0.34 CPC. Real volume, still well above benchmark.
• Pang, "Papa parle peu": solid but average. 2.22% link CTR, €0.38 CPC on 1,620 impressions. Fine, not a priority.
• Loopy, "38% rêvent...": the weakest one. 1.83% link CTR, €0.62 CPC, €11.35 CPM, only 436 impressions, and still on "Unpublished edits". Finish and publish it, or drop it.

What I'd do next:

• Move budget to Confusion and Hush, the two ads with real volume and proven results.
• Give Maman more impressions to confirm the early signal before you call it the winner.
• Track link CPC as your main metric: under €0.40 is good here, and most of your ads are already there.

Verdict: these results are good, not just luck. The hooks are working. Now concentrate your spend on the winners instead of splitting the budget across five ads at once.

You've proven the hooks work in Stories. Don't stop at that one placement, take the winners further:

• Rebuild the top hooks for other formats. Remake Maman, Confusion, and Hush for Facebook feed, Instagram feed, and Reels: the same hook idea, built to fit each format.
• Let placements compete. Run them as one campaign across placements so Meta finds the cheapest conversions, then check CPC per placement.
• Keep the hook, adapt the framing. A vertical Stories hook usually needs a proper square or in-feed version, not a straight copy, so the first second still catches attention.
• One ad, one funnel. Adapt the funnel to the hook: the first quiz question should match the ad the user just clicked. Maman's "47% / 12%" leads into a question about parents, Hush's "ex" hook into a question about exes. Each winning ad gets its own funnel variant, so the message stays consistent from the tap to the paywall.
• Drop ads by the same rule. Anything that can't keep link CPC under €0.40 after a few thousand impressions gets dropped, just like Loopy.

The bet: it's the creative angle that's working, not the placement. Prove it by running the same hooks in feed and Reels, each paired with its own funnel, and checking whether the high CTR holds all the way to the paywall.
