Ad testing checklist
Practical ways to improve ad experiments and identify winning ads
Google may assemble your ads, but ad testing still matters. Strong ad copy can improve performance for months or even years, especially when you combine automation with a clear structure.
Here’s a practical checklist to improve RSA testing.
Start with ad relevance
If your ad groups are too broad, your tests become unreliable fast. Closely related keywords, ads, and landing pages still matter.
Keep an eye on quality score and ad relevance. If Google struggles to match your ads to your keywords, it’s often a sign your structure needs tightening.
Improve data density
Too many unpinned assets create thousands of possible combinations. Most never collect enough data to learn anything useful.
That’s why many PPC teams partially pin RSAs, especially headline 1 and headline 2. You keep control, improve relevance, and help Google gather data faster.
Use the right metrics and minimums
CTR alone rarely tells the full story. Metrics like conversion per impression often give a better view of overall performance.
Before choosing a winner, define minimum data thresholds and confidence levels. Acting too early is one of the fastest ways to make bad testing decisions.
