most important facebook content and images

I'm new to running ads, so I don't know what is the most important factor in advertising? Is it content and images?

Content and images are 2 factors that are 80% important to decide whether customers are interested in your service or not.

If the content and images are not good and eye-catching, customers will not care what you are doing. But if the content and images are good, customers will stop and watch them.

So choose beautiful content and images.
