Learning: what the bid strategy is doing, and how long it takes.

Where it shows: in the status of the campaign's bid strategy.

• A new bid strategy, or a campaign switched to one.
• A target CPA or target ROAS changed by a large step.
• A big budget change, or new conversion actions in the campaign's goal.
• Many keywords, ad groups or ads added or removed at once.

1. Leave the campaign alone while it learns: each new large change restarts the clock.
2. Make changes in one batch rather than a little every day.
3. Move targets in steps of about 15 to 20 percent rather than in one jump.
4. If it stays in Learning for weeks, check the campaign gets enough conversions to learn from.

Learning usually ends within about a week, or after around 50 conversions, and longer for a campaign with few conversions.

Judge the change on the weeks after Learning ends, not on the days during it.

Batch changes to a Smart Bidding campaign into one edit a week rather than small daily ones.

Move targets in steps, and note each change and its date so you judge it after Learning ends.

Oppy runs these every week, so the status is found early.
