The glossary
Twenty terms you will meet when making Instagram carousels and reels, defined in one or two sentences each, with links to deeper posts where we have them.
- Carousel
- An Instagram post made of several swipeable slides. The Content Engine renders carousels as 1080 x 1350 px PNG slides (4:5), one idea per slide, plus a caption. Read more: carousel specs reference.
- Reel
- A short vertical video on Instagram. The engine renders reels as 1080 x 1920 px MP4 (9:16) with sound. Read more: Reels specs and safe zones.
- Hook
- The first thing a viewer sees or hears: the cover slide of a carousel or the first second of a reel. Its job is to make someone keep looking. See carousel vs reel for how the formats differ. Read more: seven first-slide hook patterns.
- Second hook
- A deliberate second hook on slide 2 of a carousel. The engine writes one for every carousel because Instagram head Adam Mosseri has said that people who do not swipe may be shown the carousel again starting from slide 2. Read more: hook patterns.
- Slide
- One frame of a carousel. A slide carries a single idea in large type so it stays readable on a phone. See size and slide count.
- CTA (call to action)
- The line that tells the viewer what to do next, such as "link in bio" or "comment a keyword". Where a CTA sits and how it is worded changes what people do. Read more: writing captions for saves.
- Comment-keyword funnel
- A funnel where a post asks viewers to comment a specific word, and an automation then sends the commenter a direct message with a link or file. It works through Meta's private replies. Our explainer: comment-to-DM funnels explained. Read more: definition and Meta rules.
- Private reply
- A single direct message that a page can send to someone who commented on its post, through Meta's official private-replies feature. Meta limits it to one message per comment, within 7 days of the comment. Read more: what Meta documents.
- DM funnel
- Any flow that moves a person from a public post into a private conversation, where an offer or a file is delivered. A comment-keyword funnel is one kind of DM funnel. Read more: how DM funnels work.
- Engagement bait
- A post that explicitly asks for comments, likes, shares or tags. Meta's guidelines treat such requests as engagement bait in most cases, which is why the wording of a CTA matters. See the funnel explainer. Read more: policy checklist.
- Faceless page
- An account that posts content without showing the creator's face or voice, using text, graphics, stock-free illustration or animated characters. Our own pages are faceless. Read more: faceless niches that work.
- Niche
- The specific audience and topic a page serves, such as fitness coaches or social media managers. The engine starts every run by checking the niche. Read more: how the niche check works.
- Niche check (verify)
- The first stage of the engine: looking at what an audience already pays for, what it posts and what it says, so the ideas start from evidence instead of a blank prompt box. Read more: the four stages.
- Outlier post
- A post that did clearly better than the account's usual. In the free audit an outlier is a post at 1.5 times the page's usual or better. Read more: what separates outliers.
- Median score
- A post's likes plus comments divided by the median post of the same account. 1.00x is a normal post for that page. It lets you compare posts without being fooled by a few huge ones or by account size. Read more: judging a save rate.
- Look (style)
- A reusable visual design the renderer applies to every slide and reel: colours, type, spacing and motion. The engine ships ready-made looks and can build a new one from your description. Read more: the looks.
- Batch rendering
- Producing many posts in one run from a queue of plans, instead of designing each post by hand. Rendering happens on your own computer, so there are no credits or per-post fees. Read more: planning a month in one afternoon.
- Plan file
- A small structured file that describes one idea: the carousel slides, two reels and the captions. The renderer reads a plan and outputs the finished files. Read more: where plan files fit.
- Safe zone
- The part of a frame that stays visible once the platform's buttons and captions cover the edges. Important text is kept inside it so nothing is hidden. Read more: safe zones for Reels.
- Link in bio
- The single clickable link on an Instagram profile. Pages that cannot put links in captions send people there. Read more: one idea, three posts.
