What it does

Every morning this workflow queries your BigQuery ad-performance table, computes each creative's CTR trend over a rolling 7-day window versus its prior baseline, and identifies the ones whose performance has decayed past a set threshold. For each flagged creative it creates a refresh brief in a Notion database so your creative team has a ready-to-action ticket instead of a raw spreadsheet row.

When to use it

Run this when you manage a meaningful number of live ad creatives and CTR erosion sneaks up on you. It's for performance marketers who want fatigue caught automatically and turned into briefed work, not a dashboard nobody checks.

How it works

A daily schedule fires the run. A BigQuery action pulls per-creative impressions and clicks for the current window and the baseline window. A logic step computes the relative CTR drop and keeps only creatives past the decay threshold with enough impressions to be significant. For each survivor, a Notion action creates a brief page pre-filled with the creative name, current vs baseline CTR, spend, and a suggested refresh angle. A final Slack output posts a digest of how many briefs were opened and links them.
