Frequently asked questions

How do I write a good advertisement?

Lead with the customer's need, say what you do and where, give one reason to choose you, add proof you can support, and ask for one action.

What are the limits for Google search ads?

Responsive search ad headlines can be up to 30 characters and descriptions up to 90 characters.

How long should ad copy be?

As short as it can be while still saying what you offer, why to choose you and what to do next.

Should I test different ad versions?

Yes. Change one thing at a time and compare leads, not clicks.

Can I make claims like best or number one?

Only if you can prove them. Unsupported claims can break platform rules and damage trust.
