Read against typical Meta benchmarks (link CTR around 1%, CPC often €0.40 to €1, a healthy CPM in the €5 to €15 band), this is a strong first run. Most of your ads are doing 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. Wins on every axis, but only 1,489 impressions, so confirm it with more budget.
• Confusion and Hush: the proven workhorses. 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 mid-pack. 2.22% link CTR, €0.38 CPC on 1,620 impressions. Fine, not a priority.
• Loopy, "38% rêvent...": the laggard. 1.83% link CTR, €0.62 CPC, €11.35 CPM, only 436 impressions, and still on "Unpublished edits". Finish and publish it, or cut it.

What I'd do next:

• Push budget to Confusion and Hush, the two with volume and proof.
• Feed Maman more impressions to confirm the early signal before you crown it.
• Track link CPC as your single number: under €0.40 here is good, and you're mostly there.

Verdict: good, not lucky. The hooks are landing. Now concentrate spend on the winners and stop starving the test by running five ads at once.

You've proven the hooks work in Stories. Don't treat that as the whole channel, spread the winners:

• Redeploy the top hooks across formats. Rebuild Maman, Confusion, and Hush for Facebook feed, Instagram feed, and Reels: same hook logic, format-native execution.
• Let placements compete. Run them as one campaign across placements so Meta finds the cheapest conversions, then read CPC per placement.
• Keep the hook, change the frame. A vertical Stories hook usually needs a square or in-feed recut, not a copy-paste, so the first second still grabs.
• One ad, one funnel. Adapt the funnel to the hook: the first quiz question should echo 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 maps to its own funnel variant, so the message never breaks from tap to paywall.
• Cut on the same rule. Anything that can't hold 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 carrying the same hooks into feed and Reels, matching each one to its own funnel, and watching whether the CTR travels all the way to the paywall.
