Marketing and strategy terms

Definitions for the strategy, planning, and analytics terms that show up across every social platform, from algorithm and engagement rate to short-form video, content pillars, and the marketing funnel.

Affiliate marketing: An arrangement where a creator, publisher, or influencer earns a commission for sending a paying customer to another company's product, almost always through a tracked link or unique discount code.
Boosted post: A boosted post is an organic social media post that you pay the platform to show to more people, with a small budget, a short run time, and a simpler set of targeting and creative options than a full ad campaign.
Brand awareness: Brand awareness is the share of your target audience who can recall or recognise your brand, measured through surveys and behavioural signals like branded search, direct traffic, social mentions, and reach.
Carousel post: A carousel post is a single social media post made up of multiple images, videos, or slides that the viewer swipes through one at a time, used to tell a longer story, walk through a how-to, or show several angles of the same idea inside one feed unit.
Character counter: A character counter is a tool that tallies the number of characters, words, and sometimes lines or paragraphs in a piece of text, used to keep a social media post, bio, ad, or video description inside the platform's character limit before it is published.
Clickbait: Clickbait is a headline, thumbnail, or post designed to make a user click by over-promising or withholding what the content is actually about, so the engagement signal is real but the underlying content under-delivers.
Community: A community is a group of people who share an interest, a fandom, or a purpose and who talk to each other (not just to the brand or the creator) inside a shared channel: a Discord server, a Slack workspace, a Geneva or Circle group, a Substack chat, a subreddit, a Facebook group, or the comments under a recurring set of posts. What turns a follower list into a community is the member-to-member conversation; the difference between an audience and a community is whether the people inside it know each other or just know you.
Community manager: A community manager is the person who runs the conversation around a brand on social media and in its owned communities, replying to comments and DMs, moderating discussions, surfacing sentiment back to the team, and turning casual followers into regulars over months and years.
Content batching: Content batching is the habit of planning, writing, and producing several pieces of social media content in one focused session, then scheduling them out instead of creating each post in the moment.
Content pillars: Content pillars are the three to five recurring themes a brand posts about on social media, used as the spine of the content calendar so every post has a home, the audience knows what the account is about, and planning stops being a blank-page exercise every week.
Creator economy: The creator economy is the wider system of creators, platforms, audiences, and payment infrastructure that lets independent people build a business out of an audience they own, rather than going through a publisher, label, studio, or employer to reach the same audience.
Cross-posting: Cross-posting is the practice of taking one piece of social media content and publishing it to more than one platform at roughly the same time, either through a platform's native sharing feature like Meta's Facebook to Instagram setup or through a third-party scheduler that pushes a single draft to several accounts in one go.
Crowdsourcing: Crowdsourcing is the practice of getting work, ideas, content, votes, or money from a large group of people rather than from staff or paid suppliers, usually through an open call online, often run as a contest, a vote, or a structured submission process with a brief.
Engagement rate: Engagement rate is the percentage of an audience that actively interacts with a piece of social media content through likes, comments, shares, saves, or clicks, divided by an audience denominator (followers, reach, impressions, or views) and multiplied by one hundred.
Evergreen content: Evergreen content is content written once and useful to readers for years: how-to articles, beginner guides, glossaries, definitions, FAQs, comparisons, and other formats that are not tied to a news cycle, a specific date, or a season, and that keep earning traffic, links, and social shares long after the publish date.
Feed: A feed in social media is the running list of posts that loads when you open an app like Instagram, TikTok, Facebook, LinkedIn, X, or YouTube, ordered by the platform's ranking software so that the posts the system predicts you will spend time on sit closest to the top of the screen and the rest get pushed down or left out.
Follower growth: Follower growth is the change in the number of accounts following a social media profile over a chosen time window, usually expressed as a percentage of the starting follower count, and used as a directional signal of whether content is reaching new audiences and converting them into a longer-term relationship with the account.
Hashtag: A hashtag is a word or phrase preceded by the # symbol, written with no spaces, that labels a social media post by topic so the platform can group it with other posts using the same tag and surface it through search and recommendation feeds.
Impressions: Impressions are the total number of times a piece of content (a post, an ad, a story, a video) appears on a screen, counted every display including repeat views by the same person, used as a measure of how often content was shown rather than how many unique people it reached.
Influencer: An influencer is a person who has built up an audience on social media large enough or engaged enough that brands pay them to talk about products, with size tiers running from nano (under 10,000 followers) to mega (over one million) and the working unit of value being the relationship of trust between the creator and the audience rather than the raw follower count.
Keyword: A keyword is the word or phrase a person types into a search bar to find content on a topic, and (in social media in 2026) the on-page signal the platform reads out of the caption, title, bio, alt text, on-screen text, and audio to decide whether a post is about that topic and should be shown when someone searches for it.
Link in bio: A link in bio is the clickable URL placed in the bio section of a social media profile, used as the one place a creator can send followers off-platform on Instagram and TikTok where individual posts do not carry clickable links, and the gap it filled built a whole category of tools (Linktree the original, plus Beacons, Stan, and Later's Linkin.bio) that route the visitor to a personal landing page of multiple links.
Long-form video: Long-form video is video content over roughly three to ten minutes (depending on what it is being contrasted with), the format YouTube was built around, which TikTok stretched to 60-minute uploads in 2024 and Instagram Reels extended to three minutes in January 2025, used for tutorials, podcasts, interviews, documentaries, and the explanatory work a 30-second clip cannot finish.
Marketing funnel: A marketing funnel is the path a stranger walks from the first time they see your content to the moment they buy, broken into three stages (top, middle, and bottom) which on social media in 2026 map to short-form video for discovery, long-form video and written posts for nurture, and retargeting ads, link in bio storefronts, and creator-led offers for the sale.
Organic marketing: Organic marketing is marketing that earns attention without paying the platform to surface the content: organic social media posts, SEO-ranked blog content, newsletters, podcasts, word-of-mouth, and community-led referrals. It is the opposite of paid marketing (ads, sponsored posts, boosted content), and on social media in 2026 it works mainly on TikTok, Instagram Reels, YouTube Shorts, and LinkedIn, where the algorithms still surface content to non-followers without an ad spend.
Quality control: Quality control on social media is the structured review every piece of content runs through before it goes live: a typo and link check, a brand voice check, the platform-spec and accessibility pass, any legal or compliance review, and the final sign-off from whoever owns the channel. It is the step that catches the post before the post catches the brand, and it lives alongside the broader quality assurance work (style guides, templates, onboarding) that is meant to keep the same errors from happening in the first place.
Reach: Reach is the number of unique accounts that saw a piece of social media content at least once, counted once per person no matter how many times the same account came back. It is the audience-size half of the analytics pair (with impressions counting total displays), and it splits into organic reach, paid reach, and viral reach depending on whether the platform showed the post for free, in exchange for ad spend, or because somebody else shared it.
Sentiment analysis: Sentiment analysis is the use of natural language processing to read social media mentions, comments, reviews, and posts and classify each one as positive, negative, or neutral, sometimes with a finer-grained emotion label (anger, joy, fear, surprise) and an aspect breakdown that scores each feature or topic separately. It is the automated version of the read a community manager used to do by hand on a few hundred comments, scaled to hundreds of thousands or millions of mentions at once.
Short-form video: Short-form video is vertical, mobile-first video content running roughly 6 seconds to 3 minutes, built for the algorithm-driven feeds on TikTok, Instagram Reels, YouTube Shorts, Facebook Reels, LinkedIn video, and Pinterest, where the viewer is scrolling and the video has two or three seconds to earn the rest of its runtime. It is the format every major platform rebuilt itself around in the early 2020s, the cheapest organic-reach surface in social media in 2026, and the working counterpart to long-form video.
SMART goals: SMART goals are goals written to a five-part test: Specific, Measurable, Achievable, Relevant, and Time-bound. The acronym was introduced by George T. Doran in a 1981 Management Review paper and has been the working way to write goals in marketing, social media, HR, and project management for four decades. On social media in 2026 the framework is the standard way to convert a vague intention ("grow Instagram") into a target the team can actually be measured against ("grow Instagram followers from 10,000 to 12,000 by 30 September 2026 by publishing three Reels per week").
Social media: Social media is the set of internet platforms (apps and websites) where users create profiles, publish content, and engage with the content other users publish, with the platform acting as the venue and the audience acting as the publishers. The category covers social networking (Facebook, LinkedIn), microblogging (X, Threads), photo and video sharing (Instagram, TikTok, YouTube, Pinterest), messaging (WhatsApp, Messenger), community platforms (Reddit, Discord), and review and aggregation sites (Yelp, Letterboxd). DataReportal's April 2026 numbers put global social media usage at 5.79 billion user identities, around two-thirds of the world's population.
Social media algorithm: A social media algorithm is a ranking and recommendation system that uses signals from people, posts, accounts, and context to decide which content appears for each user and in what order.
Social media analytics: Social media analytics is the process of collecting, reading, and acting on data from social platforms so you can understand content performance, audience behavior, and business outcomes.
Social media bio: A social media bio is the short block of text on a profile that says who you are, what you do, and where people should click next, written within a strict per-platform character limit.
Social media campaign: A social media campaign is a coordinated set of posts, ads, and other social activity, organised around one goal, one audience, and one defined start and end date, so the result can actually be measured.
Social media caption: A social media caption is the text written next to a post that gives the photo, video, or carousel its meaning, helps the algorithm understand the topic, and gives the audience a clear next step.
Sponsored post: A sponsored post is a social media post that exists because somebody paid for it. The most common shape is a creator posting from their own account in exchange for payment from a brand, with a paid partnership label attached so the audience can see it is commercial; the term also covers paid in-feed ads on Meta, X, and LinkedIn (where the platform shows the word "Sponsored" next to the post), and LinkedIn's specific in-feed ad product called Sponsored Content. Disclosure of sponsored posts is legally required in the US (FTC), the UK (ASA), and the EU.
Thought leader: A thought leader is somebody recognised by peers, customers, and the wider industry as a leading voice on a specific topic, who is consistently producing content (posts, articles, talks, books, podcasts, research) that backs up the description. The phrase was coined by Joel Kurtzman in 1994; in 2026 it sits at the centre of most B2B content strategies, with LinkedIn the dominant platform and LinkedIn Thought Leader Ads (launched March 2023) the dominant paid amplification format.
Trending: Trending on social media means a topic, hashtag, song, or video is rising in volume on the platform much faster than the usual baseline, with the platform's own algorithm flagging it as worth showing to a wider audience. The signal is velocity rather than absolute volume; the surfaces that display it (X Trends, TikTok Trends, YouTube Trending, Google Trends) all use related but slightly different methodologies, and the windows in which something stays trending range from a few hours on X to a few weeks on TikTok.
URL shortener: A URL shortener is a service that takes a long web address and returns a much shorter one that redirects to the original. The mechanism is an HTTP redirect (usually 301 or 302), the most common shorteners in 2026 are Bitly, TinyURL, Rebrandly, Short.io, and Cuttly, the social platforms run their own shorteners as well (t.co on X, lnkd.in on LinkedIn, fb.me on Facebook), and Google's goo.gl was shut down in August 2025 for inactive links.
Viral: On social media, viral describes a piece of content that has spread rapidly and widely through the platform under its own momentum, far beyond the original poster's usual audience, on the back of reshares, reposts, comments, and algorithmic amplification. The threshold is not set by any platform; in practice it is around 1 million views in 3 days on TikTok, 5 million+ in a week on YouTube long-form, and 500,000 to 1 million in a few days on Instagram or Facebook.
Vlog: A vlog (video blog or video log) is a video format in which a creator narrates their own life, work, travel, opinions, or routine to camera, posted on YouTube or short-form platforms as a series, with the creator as the through-line. Merriam-Webster dates the first known print use of the word to 2002; the first published vlog ran from 2 January 2000.
Watermark: A watermark is a logo, handle, name, or signature laid over an image or video to mark ownership, source, or attribution, the visible kind is the TikTok bouncing logo or a photographer's name in the corner of a photo; the invisible kind is the imperceptible signal Google's SynthID and the C2PA Content Credentials standard embed into AI-generated and camera-captured files.

Social media acronyms

What the three-letter shorthand actually stands for, from CAC, ROI, and KPI to UGC, FYP, OOTD, and the rest of the abbreviations that appear in social and marketing comments every day.

CAC: CAC, short for customer acquisition cost, is the average amount a business spends in sales and marketing to turn one new person into a paying customer; the working formula is total sales and marketing spend over a period divided by the number of new customers acquired in the same period, and the working benchmark is that CAC should come in at less than a third of the customer's lifetime value.
CFBR (commenting for better reach): CFBR stands for commenting for better reach, a LinkedIn comment convention where a reader adds a short comment (sometimes literally the four letters) to help push the post into more feeds; the working version is a real one-sentence comment from a relevant person, the lazy version of a standalone CFBR is now down-weighted by the LinkedIn algorithm and discouraged by LinkedIn's policies on coordinated engagement.
DM: DM stands for direct message, the private inbox a social platform gives to each account so two people can talk one-to-one without the public seeing it; the same idea sits behind Instagram DMs, X (Twitter) direct messages, LinkedIn messages, TikTok DMs, the Threads inbox, and the message-request folder for senders the account does not already follow.
FYP: FYP stands for For You Page, the personalised vertical-video feed TikTok shows by default when the app opens; every account gets a different FYP picked by a recommender system that watches what the user finishes, rewatches, likes, shares, comments on, follows, and skips, and the same idea now drives the For You feeds on Instagram Reels, Threads, Facebook Reels, Pinterest, and Snapchat Spotlight.
GIF: GIF stands for Graphics Interchange Format, a bitmap image format that CompuServe released in June 1987 and a 1989 update made capable of looping animation; the format is best known today as the short, silent, looping reaction clips that live on Giphy, Tenor, Klipy, and the GIF keyboards inside almost every messaging and social app.
GRWM (Get Ready With Me): GRWM stands for Get Ready With Me, a video format where a creator films themselves getting ready (makeup, hair, skincare, outfit) while talking to the camera as if the viewer were sitting on the bathroom counter; it started on YouTube in the early 2010s, migrated through Instagram, and has been one of TikTok's largest single content categories since the pandemic.
JPEG: JPEG stands for Joint Photographic Experts Group, the committee that published the format in 1992 (ratified as ITU-T T.81 the same year and ISO/IEC 10918-1 in 1994); it is the lossy image compression standard built for photographs and the .jpg and .jpeg extensions name the same format, with the difference dating to the 8.3-character filename limit on early Windows.
KOL (Key Opinion Leader): KOL stands for Key Opinion Leader, a person whose audience trusts their judgement on a specific topic enough that the audience's opinions and buying decisions shift when the KOL speaks; in Chinese and wider Asian consumer marketing the word is the regional term for influencer, and in Western pharma and medical marketing it is a senior doctor or researcher whose endorsement moves prescribing behaviour among their peers.
KPI: KPI stands for Key Performance Indicator, a measurable number a team has agreed is a load-bearing measure of success against a specific goal; the word "key" is the active part, because KPIs are the small set of metrics that move the goal, kept separate from the longer list a team tracks for context.

Platform feature definitions

What specific features mean and do across Instagram, TikTok, LinkedIn, YouTube, X, Threads, and Pinterest, written for marketers and creators who want a one-line answer.

Stickers: Stickers are small interactive or decorative graphics that social platforms let you drop on top of a Story, Reel, feed post, message, or Live broadcast. Some stickers do a job (poll, question, link, music, location, countdown, quiz), some are pure decoration (GIF, emoji, cutout, frame, mention), and some are full message-app sticker packs that people send each other on WhatsApp, iMessage, Telegram, Messenger, and Snapchat.

Internet culture and slang

Loose, evolving language from the wider creator and platform ecosystem, kept current so the entries reflect how the words are actually used right now rather than two years ago.

Emoji: An emoji is a small picture character encoded in the Unicode Standard with its own name and codepoint, drawn slightly differently by each operating system, used inside text to add tone, emphasis, or a quick visual shorthand that the words on their own would have to spell out.
Meme: A meme is a piece of culture (an image, a video, a phrase, a sound, a joke template) that spreads online by being copied and remixed, originally coined by Richard Dawkins in The Selfish Gene in 1976 as the cultural counterpart to a gene, and now the working language of the For You page on TikTok, the Explore tab on Instagram, the home feed on X, and the recommended-videos rail on YouTube.

About this social media glossary

This glossary is a free, working dictionary of social media, content marketing, and creator-economy terms, written for marketers, social media managers, agency teams, and creators who want a clear answer without a twenty-minute read.

The entries are written and maintained by the team that builds Maeve, the social media scheduling platform behind the rest of the site, so each definition is grounded in how the term actually shows up in a working content calendar rather than in a textbook. Definitions are reviewed and updated when platform behaviour changes, with the publish and update dates surfaced on every entry.

Each entry follows the same shape: a short summary at the top for the quick lookup, a longer breakdown underneath with examples and common usage, and a link out to the relevant free tool or editorial guide when the term has one. If you are evaluating Maeve itself, the pricing page has the current plans.
