Build an RPM tracker that catches ad-rate shifts
Sources say creators only notice ad-rate drops a month late, after a payout shocks them. The tracking setup one media-company editor uses:
—
Log RPM weekly by content category, not channel-wide — gaming and finance move differently.
—
Flag any single-week swing over 15% — that's usually a seasonal or policy shift, not your content.
—
Cross-check 'monetized playbacks' against views; a widening gap means more videos got limited ads.
—
Keep a note column for the date so you can match dips to platform news later.
Confidence: medium-high. For your channel, the spreadsheet is how you spot a demonetization creep before it costs you a quarter.
