Test asking the right question in Facebook ad

Idea: Try asking questions in your ad copy to make a user visitor curious to learn more about your offer and therefore click. 

Details: Attached is an awesome example by HubSpot. What makes this ad so good?

1. It asks a question marketers are curious to find out
   
2. It offers to answer the question for free
   
3. It has proof by numbers (check the text on top of the image)
   
4. It shows a clear benefit (Improve your SEO)
   
5. It says you can get a free 30-day trial (another free offer)
   

If you’re able to apply all these tips to one ad campaign, you’re onto something!
