AOV (Average Order Value)
The average dollar amount a customer spends per purchase. Nudging it up is often cheaper than chasing new buyers.
Conversion
When someone takes the action you actually wanted, whether that's a purchase, a sign-up, or a booked call. Everything else is just traffic.
CPC (Cost Per Click)
What you pay each time someone clicks your ad. Tells you how much a single interested visitor costs.
CPL (Cost Per Lead)
What it costs in ad spend to generate one lead (a form fill, a call, a booked demo). The number that tells you if paid is actually feeding your pipeline.
CPM (Cost Per Mille)
What you pay to get your ad in front of 1,000 people. The base price of attention on a platform.
CTR (Click-Through Rate)
The percentage of people who saw your ad and clicked it. Low CTR usually means the creative or the offer isn't pulling its weight.
Engagement Rate
The percentage of people who saw your post and actually did something about it (liked, commented, shared, saved). The truest gut-check on whether content lands, not just how far it traveled.
Follower vs Reach
Followers are your subscribers; reach is who actually saw a given post, which is usually a fraction of them. Big follower counts don't pay the bills.
Impressions
The total number of times your content was displayed, including the same person seeing it more than once. Always higher than reach.
Reach
The number of unique people who saw your content at least once. Reach is how many humans, not how many views.
ROAS (Return On Ad Spend)
How much revenue you earn for every dollar of ad spend. A 4x ROAS means $4 back for every $1 in. The scoreboard for paid social.
Saves
When someone bookmarks your post to come back to it. One of the strongest signals you made something genuinely worth keeping.
Vanity Metrics
Numbers that look impressive but don't move the business, like raw follower counts and total likes. Fun to screenshot, useless in a P&L.
