CTR usually goes up when the ad feels specific and hits the right audience.
For example:
- Bad ad: “Grow your business faster” (not specific, sounds clickbait-y, doesn't say who's it for).
- Better ad: “Still getting clicks from people who never buy? Fix it with [your solution]” (more specific, probably meant for ecom owners, gives a hint that you have the solution to this problem).
So it's just about being more specific about your audience, their problem, your product, and how the product solves the problem.
You can run some A/B tests to see what ad approach works in your case: pain point, mistake, comparison, result, objection. Then test the visuals. Carousels and videos tend to work better than static images, but not always. So experiment with formats as well.
For the audience, test Advantage+ audience vs. manually created audiences. Try different targeting filters, custom audiences, etc. You can also try targeting tools for more specific audiences (I use leadenforce for that). Compare different types of audiences and scale the better ones.
Also don’t chase CTR too much. It’s easy to write clickbait and get cheap clicks from the wrong people. I’d rather have lower CTR with better leads/sales than a high CTR but no $$$ coming through.
