How to use this tool
Make each asset earn its place
Use distinct benefits, evidence and calls to action across your headlines. Read combinations aloud: assets should make sense together and on their own. Repeating the same idea in several headlines reduces the variety available for testing.
Use the preview as a writing aid
The preview uses your first three headlines and first two descriptions. It does not reproduce every Google placement or predict which assets will appear. Character counts alone cannot validate advertising policies, trademarks, claims, landing pages or Ad Strength.
A worked example
A headline with 31 standard Latin characters is one character over the limit. The checker identifies the exact asset so you can shorten it, while leaving your original copy available to edit.
