An attribution window (called “attribution setting” in Meta) is the period after someone interacts with your ad (usually via click) during which a resulting conversion (in the case of a streaming campaign: clicking through to Spotify) is credited to that ad.
Why for Most Fast-Conversion Music Campaigns, 1-Day Click is the Better Choice
Given what we see in many streaming-promo campaigns ‒ especially those using FeatureFM or similar landing pages where the listener’ path is: Ad → landing page → Spotify (single primary action).
…the conversion usually happens immediately or very shortly after someone clicks. That makes 1-day click attribution the more aligned setting.
Meta also uses that window to optimize delivery (show your ads to people likely to convert within that timeframe). If someone converts outside that window, the conversion isn’t usually counted or used by Meta’s learning algorithm.
Here’s why:
Faster feedback & optimization - With 1-day click, you’ll see earlier which creatives, messages, and targeting are working because delayed conversions don’t muddy the waters.
Cleaner data for what actually drove action - Since conversions are happening quickly, a longer window just introduces ambiguity: did someone click your ad, or did they later arrive via search, another ad, or organic?
Better ad delivery learning - Meta will optimize toward people who are likely to act fast, helping your spend more efficiently.
ROI clarity - For artists or small budgets, you want to know where every dollar went. Short windows make that more visible.
When You Might Still Consider a 7-Day Click Window
Even though 1-day click is usually better for fast funnel campaigns, there are cases where 7-day click is useful:
When you suspect a lot of delayed converts (maybe fans who click, then wait until later to open Spotify, or return from email reminders).
If you’re running a more complex funnel e.g. ads → landing page → email or re-engagement → Spotify (that takes more than a day).
For cross-channel campaigns where attribution across touchpoints might require more time to accumulate.
Key Considerations & Trade-Offs
Reported Conversions vs. True Impact
A 7-day window will often show more conversions in your dashboard. That doesn’t always mean “better performance”. Some of those conversions may have come from other sources but still fall within the window.Learning Period & Budget Efficiency
Meta’s optimization works on historical signal. If many people convert within 24 hours, a 1-day window gives stronger signals faster. But if you’ve very few conversions early, the algorithm may need more time or volume.Comparability
Always note which attribution setting you’re using. If you compare two campaigns and one uses 1-day click and the other 7-day, the reported performance isn’t apples-to-apples.Pixel + Conversion API Setup
Having both pixel + CAPI is great, it increases delivery and reporting accuracy. But even with good tracking, attribution windows shape what Meta considers as “actionable” data for optimization.View / Engaged-View Windows
Since you’re using video creatives, you can get additional insights (and incremental conversions) via view-through or engaged-view windows. These capture people who didn’t click immediately but watched enough of the video to be influenced. Use them in reports to see full effect, even if you optimize primarily on click.
Our recommendation: What We Do (and What We’d Do for You)
If we’re building a music/streaming campaign for an artist, and the conversion goal is clicking through to Spotify (via FeatureFM or equivalent), with most action happening immediately, here’s our setup:
Attribution setting: 1-day click
Engaged-view (for videos): 1-day
View-through: either none or 1-day (only if we suspect many conversions from exposure without click)
Use pixel + Conversion API so that if any tracking gaps occur, we still collect as much signal as possible
Monitor performance closely (within first 24-48 hours) and adjust creatives and targeting rapidly
Bottom Line
If you want action now (like streams, saves, clicks immediately after an ad) and you already have a light, direct path (FeatureFM → Spotify), then 1-day click attribution will give you the cleanest, fastest results.
Longer windows let you see “lagged” impact, but they can blur what’s actually working vs what’s just noise. Pick the window that reflects your fan’s behavior. In your case, that behavior is fast, which means you should run your campaigns like it.
