The setting that quietly rewrites your results

Meta calls it the attribution setting. Most people call it the click window. It's the stretch of time after someone clicks your ad during which a resulting action, for a streaming campaign that's the click through to Spotify, still gets credited to that ad. You pick 1-day click or 7-day click, and that choice changes how your ads deliver, what shows up in your dashboard, and how you read the whole campaign.

For most streaming-promo campaigns I'd default to 1-day click. Here's the reasoning.

Why 1-day click usually wins for streaming ads

Look at the path a listener actually takes on a FeatureFM (or similar) funnel: ad, landing page, Spotify. One primary action, and it usually happens within minutes of the click, not days later. On that kind of funnel the click and the Spotify open generally land in the same session; I rarely see the save show up more than a few hours after the click.

Meta uses that same window to optimize delivery, so it shows your ads to people likely to act inside that timeframe. A conversion that happens outside the window mostly doesn't get counted or fed back into the learning. On a fast funnel that's fine, because almost all the real action is inside the first day anyway.

A short window gives you faster feedback. You see which creatives, messages, and audiences are working sooner, because lagged conversions aren't muddying the read. It keeps the data cleaner too: when conversions land quickly, a longer window mostly adds ambiguity about whether someone came from your ad or wandered in later from search, another ad, or organic. And for an artist on a small budget, you want to see where every dollar went. Short windows make that visible.

When 7-day click is the better call

1-day isn't a rule for every campaign. A 7-day window earns its place when the path to conversion is genuinely slower:

• You've got real reason to expect delayed converters: fans who click, then come back to open Spotify later, or return from an email reminder.

• The funnel is longer than a single tap, more like ad, landing page, email or re-engagement, then Spotify.

• It's a cross-channel campaign where credit accumulates across touchpoints over several days.

If any of those describe your setup, a short window will undercount you and a 7-day read is closer to the truth.

Trade-offs worth knowing before you pick

A 7-day window will usually report more conversions on the dashboard. That's not automatically better performance; some of those conversions came from other sources and just happened to fall inside the window. More reported is not the same as more caused.

Meta's optimization runs on historical signal. If most people convert within 24 hours, a 1-day window hands the algorithm a stronger, faster signal. If you have very few conversions early, it may need more time or volume before it settles, and a longer window can help it find its feet.

Always note which setting a campaign used. Compare a 1-day campaign against a 7-day one and the reported numbers aren't apples to apples. That mismatch has thrown off more than one performance review.

Run both the pixel and the Conversion API if you can. It improves delivery and reporting accuracy. Good tracking still doesn't change the fact that the attribution window decides what Meta treats as actionable for optimization.

If you're running video, you also have view-through and engaged-view windows. Those capture people who didn't click right away but watched enough to be influenced. I use them in reporting to see the fuller effect, even when I optimize on the click.

What I'd actually set for a streaming campaign

For an artist campaign where the goal is a click through to Spotify via FeatureFM and most of the action happens right after the ad:

• Attribution setting: 1-day click

• Engaged-view (for video): 1-day

• View-through: none, or 1-day only if I suspect a lot of exposure-driven conversions without a click

• Pixel plus Conversion API, so tracking gaps cost you as little signal as possible

• Watch it closely in the first 24 to 48 hours and move on creative and targeting fast

One thing to expect the first time you flip a live campaign from 7-day to 1-day: your reported conversions drop and it looks like something broke. Nothing broke. You just stopped counting the lagged and cross-channel credit. The cost per result you're seeing now is closer to what the ad actually did.

Pick the window that matches how your listeners behave. On a light, direct FeatureFM-to-Spotify path, that behavior is fast, so 1-day click gives you the cleanest, quickest read. Longer windows show you the lagged impact, at the cost of blurring what's working against what's just noise.
