What is a social media glossary?

A social media glossary is a list of the words people use when they talk about social media and online marketing, each explained in a sentence or two. It helps when a report, a client or a comment uses a term you half know.

This one covers 120 terms: numbers from your analytics, words for types of posts and ads, and slang you'll meet in comments.

The numbers people mix up

The terms people confuse most are the ones in their analytics. They sound alike but count different things, so a post can have a high reach and a low engagement rate at the same time.

TermWhat it counts
ReachDifferent people who saw your post
ImpressionsTimes your post was shown, counting repeats
EngagementLikes, comments, shares, saves and clicks on a post
Engagement rateEngagement divided by reach or followers, as a percent
CTRClicks divided by impressions, as a percent

Put the words to work

Knowing the terms helps you read your numbers. To see them for a real account, try the Twitter analytics tool, or look up any profile's best posts with the Twitter viewer.
