You will want to adjust your target audience to reach the people who will act upon your page, as well as ensuring it reaches a maximum audience.

When you are adjusting your selections, it will give you an estimate of how many likes, views, clicks, etc that this promotion should return.

It is a good practice to tinker with these selections until you are happy with the expected outcome.

TIPS:

In my experience, you will get more expected views if you pick a smaller number of keywords and stick with one country. This will ensure Facebook can locate viewers who share all of the traits you are looking for to reach the maximum potential.

If you pick a high number of keywords, the potential audience becomes smaller (although this should be a very focused group and you may see results)

It's best to try a few different styles and see what works for you!
