In the first unit, we discussed CPM and CPC

and the value of your inventory to advertisers. In this unit, we will explain

how clicks contribute to your overall revenue

and how you can choose ad locations and styles

that are easy for users to interact with, but do not interfere

with your content. The most common measurement for click activity

is clickthrough rate or CTR. CTR is the number of

ad clicks divided by the number of impressions, page views, or queries

you received. CTR equals clicks,

divided by the number of impressions, views, or queries,

multiplied by 100 percent. For example

if you received seven clicks and one thousand page views,

your CTR would be .7 percent. As we mentioned,

CTR is just one of the three key components of your revenue

in addition to CPC and CPM. In the following lessons, we will share various

techniques for making

ads visible and easily accessible for users who are interested in your ads.

Keep in mind though that your high-quality content is what will keep users returning

again and again. The goal of this unit is to share best practices

around ad location and ad format that can help users

interact with your ads when they want to. Let's get started!
