Now, lets do some targeting

Scroll up to "who do you want your adverts to reach?"

First, "location" depends on the country. Advanced countries have higher CPC than others. So, Choose a country and scroll down to check the effect on the price of the click.

Choose some countries with cheap CPC "will add a list of these countries"

Choose age and gender according to your niche AND check the price change.

Choose the language according to your link language.

Then, choose the interests and behaviour as you see fit and keep in mind that better-educated targeting will be more expensive.

Always check the price change after you target an audience.

That was the main idea. Always check the price after you target a new audience. You will learn more about it and which audience is expensive and which is cheap and it will be like common sense to you.
