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.

1

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.

2

Write assets with purpose

Don’t just add 15 headlines because Google allows it. Use a balanced mix of:

• Relevance headlines

• Benefits

• Authority statements

• Calls to action

Match your messaging to intent. Someone researching needs different messaging from someone ready to buy.

3

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.

4

Choose the right testing setup

Adalysis automatically sets up single ad group testing for groups with at least two ads. You can also run larger theme-based tests across multiple ad groups to compare ideas like:

• Pricing vs. quality

• Reviews vs. offers

• CTAs vs. authority statements

5

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.
