Social media glossary

Plain-English definitions of the scheduling, creator, and platform terms you'll run into, in plain words.

A

  • Algorithm

    The ranking system a platform uses to decide which posts to show each user, and in what order, in their feed.

  • Alt text

    Alt text is a written description of an image that screen readers read aloud, so people who cannot see the image still get what it shows.

  • Analytics

    The data and reporting that show how your content performed (reach, engagement, clicks, follower growth) so you can learn what works.

  • API

    An Application Programming Interface: the official channel through which apps like schedulers connect to a platform to publish and read data.

  • Approval workflow

    A review step that routes draft posts to an approver before they publish, so nothing goes live without a sign-off.

B

  • Best time to post

    The windows when your specific audience is most active and likely to see and engage with a post soon after it's published.

  • Brand voice

    The consistent personality and tone a brand or creator uses across everything they publish, so their content sounds recognizably 'them.'

  • Buffer time

    Deliberate spacing left between scheduled posts so content doesn't publish back-to-back and overwhelm your audience.

C

  • Carousel

    A carousel is a post of several slides that readers swipe through one at a time. On LinkedIn it is usually a PDF document shown as swipeable pages.

  • Character limit

    A character limit is the most text a platform accepts in one post. X allows 280 characters (25,000 with Premium); a LinkedIn post allows 3,000.

  • Content calendar

    A content calendar is a dated plan of what you will post, on which platform and when, so posting follows a plan instead of the mood of the day.

  • Content pillars

    Content pillars are the three to five themes you post about again and again, so people know what to expect from you and you always know what to write next.

  • Cross-posting

    Publishing the same or adapted content to multiple platforms, ideally tailored to each instead of duplicated everywhere.

  • CTA (call to action)

    A direct prompt telling readers what to do next (follow, comment, click, sign up), turning passive attention into action.

D

  • Draft

    An unpublished, in-progress version of a post, saved so you can refine it, get it approved, or schedule it later.

  • Dwell time

    Dwell time is how long someone spends on a post before scrolling on or leaving. LinkedIn and X both use time spent as a signal when ranking feeds.

E

  • Engagement rate

    Engagement rate is the share of views that turned into an interaction. X and LinkedIn Pages both calculate it as interactions divided by impressions.

  • Evergreen content

    Content that stays relevant and useful long after it's published, rather than losing value as news or trends move on.

F

  • Feed

    The scrolling stream of posts a platform shows a user, now almost always algorithmically ranked rather than strictly chronological.

  • First comment

    The comment a creator posts on their own post immediately after publishing, often used to place links without hurting reach.

G

  • Ghostwriting

    Writing content that's published under someone else's name, common on LinkedIn and X, where writers craft posts for founders and executives.

H

  • Hook

    The opening line of a post, the first thing readers see, written to stop the scroll and earn the click on 'see more.'

I

  • Impressions

    Impressions are the number of times a post was shown on screen. Repeat views count again, so one person can add several impressions.

P

  • Post preview

    A rendering that shows exactly how a post will appear on a platform before you publish: truncation, formatting, media, and all.

  • Premium / Blue

    X's paid subscription (formerly Twitter Blue, now X Premium) that bundles a verification checkmark with reach, longer posts, and other perks.

Q

  • Quote post

    Sharing another post while adding your own commentary on top: a repost that starts a conversation instead of silently amplifying.

R

  • Reach vs impressions

    Reach counts the unique people who saw a post; impressions count every time it was shown, repeats included. Impressions are always at least as high as reach.

  • Repurposing

    Reworking one piece of content into multiple formats or platforms to get more value from a single idea.

S

  • Scheduling queue

    A set of predefined time slots you fill with posts, so content publishes automatically at your chosen times without picking a date each time.

  • Shadowban

    A suspected, unannounced reduction in a post or account's visibility, where content is quietly shown to fewer people without a formal notice.

  • Social listening

    Monitoring social platforms for mentions of your brand, competitors, or topics to understand sentiment and spot opportunities.

  • Swipe file

    A personal collection of posts, hooks, and formats that worked, saved as inspiration and reference for your own content.

T

  • Thread

    A thread is a series of connected posts from one person on X, each continuing the one before, used to say more than one 280-character post allows.

U

  • UTM parameters

    Tags added to a link's URL that tell your analytics tool where a visitor came from: which platform, campaign, and post drove the click.

V

  • Verification

    A platform badge indicating an account's identity has been confirmed, historically for notable figures, now often part of paid subscriptions.
