Social media glossary

Plain-English definitions of the social media terms small businesses run into: engagement rate, reach, content pillars, cross-posting and more, each with an example.

AI social media manager
An AI social media manager is software that plans, writes, designs and schedules social media posts for a business, so a person reviews and approves the work instead of making every post by hand.
Banned hashtags
Banned hashtags are hashtags a platform hides or limits, usually because they were used for spam or content that breaks its rules, so posts using them get less reach.
Best time to post
The best time to post is when the people you want to reach are most likely to be online and scrolling, which differs by audience, platform and time zone.
Brand voice
Brand voice is the consistent personality in how a business writes and speaks, such as warm and casual or precise and formal, across all its posts and messages.
Call to action (CTA)
A call to action is the part of a post that tells people the next step to take, such as book now, comment below, or tap the link in bio.
Carousel post
A carousel post is a single post with several images or videos that people swipe through, available on platforms such as Instagram, Facebook and TikTok.
Character limit
A character limit is the maximum number of characters a platform allows in a post, caption, bio or comment; text over the limit is cut off or can't be posted.
Content calendar
A content calendar is a schedule of what you will post, on which platform, and when, usually planned a week or a month ahead.
Content pillars
Content pillars are the three to five recurring topics a brand posts about, such as tips, behind the scenes, customer stories and offers.
Content repurposing
Content repurposing is turning one piece of content into several others, such as a blog post into a carousel, a short video and a quote graphic.
Cross-posting
Cross-posting is publishing the same piece of content to more than one social media platform, ideally adjusted to fit each platform's format and audience.
Engagement rate
Engagement rate is the share of people who interacted with a post (likes, comments, shares, saves or clicks), usually calculated as total engagements divided by reach or by followers, times 100.
Evergreen content
Evergreen content is content that stays useful long after it's posted, such as how-to tips, FAQs and guides, as opposed to news or time-limited offers.
First comment
A first comment is a comment the account owner adds to its own post right after publishing, often to hold hashtags, a link or extra details without crowding the caption.
Hashtag
A hashtag is a word or phrase after a # symbol, such as #coffeelover, that groups posts on the same topic so people can find them by searching or following the tag.
Impressions
Impressions are the total number of times a post was shown on screen, including repeat views by the same person.
Posting frequency
Posting frequency is how often an account publishes, for example three times a week on Instagram or once a day on X.
Reach
Reach is the number of unique people who saw a post or account at least once in a given period.
Social media audit
A social media audit is a review of all a business's social accounts to check what's working, what isn't, and what to change: profiles, posting habits, results and consistency.
Social media scheduler
A social media scheduler is a tool that publishes posts to your social accounts at a date and time you choose, so you can prepare posts in advance instead of posting live.
User-generated content (UGC)
User-generated content is content created by customers rather than the brand, such as photos, reviews and videos of them using a product, which the brand may share with permission.
