What is the best way to track clicks and impression statistics?

You can track clicks and impressions in three ways: through URLs, pixels, or cookies. There are specific codes placed in URLs that help analytics software track impressions. Pixels are small transparent images that are placed over ads that tell how many times the ad has been viewed. Cookies store user information like their behavior, and preferences. They are best used in retargeting ads.

If you want to track across platforms Facebook's meta pixel is great to track Facebook campaigns. There's also the Google Ads Manager where you can track impressions, clicks, call clicks, and ap actions.
