Terms

First comment

A first comment is a comment the account posts under its own post right after publishing.

Carousel

A carousel is one post that holds several images or videos a viewer swipes through.

Reels versus Shorts

Reels are Instagram's and Facebook's short vertical videos, and Shorts are YouTube's.

Trial Reels

A Trial Reel is an Instagram Reel shown first to people who do not follow the account, so you can test it before it reaches followers.

Alt text

Alt text is a short written description of an image, read aloud by screen readers and shown when the image does not load.

UTM parameters

UTM parameters are tags added to a link's query string, such as utm_source and utm_campaign, that analytics tools read to tell which post or campaign sent a visit.

Hashtag

A hashtag is a word or phrase after a hash sign that turns into a link to other posts using it.

Thread

A thread is a chain of connected posts, each a reply to the one before, used to say more than one post allows.

Content calendar

A content calendar is a schedule showing what will be posted, where and when, laid out by day, week or month.

Queue

A queue is a line of scheduled posts that go out in order at the times your weekly slots set, so you can load a week or a month of posts without choosing a time for each.

Time slot

A time slot is a recurring weekday and time, such as Tuesday at 9:00, set for an account.

Evergreen content

Evergreen content stays useful long after it is posted, such as a how-to or a checklist, so it can be shared again.

Cross-posting

Cross-posting is sending the same post to several networks.

Scheduled post

A scheduled post is a post saved with a future time, which a tool publishes for you when that time arrives, so you do not need to be online.

RSS auto-post

RSS auto-posting turns each new item in a feed, such as a blog, into a post.

Engagement rate

Engagement rate is the share of people who reached a post that also did something with it, usually likes, comments, shares and clicks added together and divided by reach or impressions.

Impressions

Impressions count how many times a post was shown on a screen, including repeat views by the same person.

Reach

Reach is the number of different people who saw a post, counting each person once however many times it was shown.

Call to action

A call to action is the line that tells readers what to do next, such as book a table, read the guide or reply with a question.

Caption

A caption is the text that goes with an image or video in a post.

Grapheme

A grapheme is what a reader sees as one character: a letter, a letter with its accent, or an emoji with its skin tone.

Webhook

A webhook is a message one system sends to a web address you choose when something happens, such as a post being published.

API key

An API key is a secret string that identifies the person or program calling a service's API.

Rate limit

A rate limit is a cap on how many requests or posts are allowed in a period, such as 100 per 15 minutes.

OAuth

OAuth is the standard way to let one app act on your account at another service without sharing your password.

Approval workflow

An approval workflow sends a post to a reviewer before it can publish.

Review link

A review link is a web address that shows a post, with the version for each network, to someone who has no login so they can comment and approve it.

Workspace

A workspace is a separate space in 1Post with its own connected accounts, calendar, members and settings, usually one per brand or client.

Bulk scheduling

Bulk scheduling creates many posts at once from a spreadsheet, one row per post with its text, networks and time.

Story

A Story is a short image or video that shows for a limited time, usually a day, on networks such as Instagram and Facebook.

Poll

A poll is a post that asks a question with a few answer choices people vote on for a limited time.

From one post to every feed

Plan the week in one sitting, keep your team in the loop, and let 1Post publish on time while you get on with the rest of your day.
