Spend: Spend is the net advertising cost. This does not include management fees, creative or anything else - purely the advertising hard cost.

Impressions: Impressions are the amount of times ads appeared, or were shown, in the given channel. Essentially how many ads were served by the advertising spend.

Click-through Rate (CTR): CTR is the rate at which impressions result in a viewer of the ad clicking on it. If 100 ads are shown and 1 person clicks, that is a 1% CTR. Clicks / Impressions = CTR

Conversion Rate: Conversion rate is the rate at which a click turns into a conversion action such as a lead form submission, ebook download, email opt-in, sale, etc. Conversions / Clicks = Conversion Rate
