Google shared a few videos about the AdWords Campaign Experiments (ACE) that walk you through some example experiments you might want to try.
With these five new videos, you can learn how to divide your experiment into control and experiment groups as well as how to run these four experiment types:
AdWords Campaign Experiments - Control vs. Experiment:
- Keyword match types (e.g., How does adding a modified broad match keyword affect my account?)
AdWords Campaign Experiments - Match Type Experiment Demo:
- Bids (e.g., What happens if I increase my bids by 10%?)
AdWords Campaign Experiments - Bid Experiment Demo:
- Ad creatives (e.g., How does new ad text and a new display URL affect my performance?)
Ad Creative Experiment Demo:
- Ad groups (e.g., Does a broader or more tightly themed ad group structure work better for me?)
