Which Instagram marketing terms does Meta define?
Instagram marketing terms come from three places: Meta's own documentation, the creator community, and the software vendors selling automation. This glossary tags all 60 terms with which of the three it belongs to, and names the Meta document when there is one.
The distinction matters when you're reading a report or briefing a client. Reach and frequency mean one specific thing because Meta defines them. Engagement rate does not appear anywhere in Meta's Glossary of Ad Terms, so every tool computes it differently. Shadowban has no Meta definition at all. Knowing which is which tells you when to trust a number and when to ask how it was worked out.
How to use this glossary
How the tags work
One term, one source label
Example:
The glossary opens with nothing typed and both filters set to All, and the line above the list reads "60 of 60 terms. 39 Meta-documented, 13 community, 8 vendor." The first entry is Account value, tagged Vendor coinage and Metrics, defined as "A price a calculator puts on an account from its followers." The second is Accounts engaged, tagged Meta: developer docs. The last is Webhook.
Five labels sort the sixty terms. Three of them mean Meta documents the wording, and the label names where; the other two mean Meta doesn't use the word at all.
Labels age. Instagram renames features often; a label more than a few months old is worth re-checking at its source.
Why the source label matters
The other glossaries, counted
We counted the entries in the five most popular Instagram and social media glossaries in August 2026. An entry counts as source-tagged only when its own text says whether the term is Meta's vocabulary or not.
| Glossary | Date shown | Entries counted | Entries with a source tag | Tags every entry by source |
|---|---|---|---|---|
| CreatorFlow, Instagram Glossary | Last updated 23 July 2026 | 82 | 1 (shadowban) | No |
| RateMyInsta, Instagram Terms Glossary | Last updated 3 September 2025 | 137 | 1 (shadowban) | No |
| Hashmeta, Social Media Glossary | No date shown | 208 | 0 | No |
| Brandwatch, Social Media Glossary | No date shown | 110 | 0 | No |
| HubSpot, Social Media Definitions | No date shown | 184 | 0 | No |
| All five | August 2026 | 721 | 2 | None |
| This page | August 2026 | 60 | 60 | Yes |
A sixth page, Strike Social's Instagram advertising handbook, sits outside the totals because its terms are bold phrases inside prose rather than a countable list. Credit where due: it links Instagram and Meta documentation three times inside its entries, more than any page in the table.
Most glossaries print community jargon and Meta vocabulary in the same typeface, so both read as fact.
Instagram renames features and retires metrics; an undated definition can be years stale.
Engagement rate, open rate and account value have no platform definition, so two tools give two answers.
Start with the metrics filter, because brand briefs quote reach and views and mean two different things by them.
Read the DM automation terms first, since your funnel lives inside private replies and the messaging window.
The ads filter is your set: CPM, frequency and ROAS all carry Meta definitions you can quote back.
Send this to a client before a reporting call, so both sides use one definition of engagement rate.
A term you cannot trace to a document is a term you cannot argue with. Before you quote an Instagram number, find out whether Meta defines it, a creator coined it, or a vendor sold it to you.

Frequently asked questions
Five labels sort the sixty terms, each applied by hand against its source in August 2026. Three of them mean Meta documents the wording: Meta Help Center for terms found in Instagram's own Help Center, Meta developer docs for terms in the Instagram Platform reference on developers.facebook.com, and Meta ads help for terms in the Meta Business Help Center, including its Glossary of Ad Terms. The other two labels mean Meta does not use the word. Community term means creators and marketers coined it. Vendor coinage means the software companies selling automation named it. Thirty-nine of the sixty terms are Meta-documented, thirteen are community terms and eight are vendor coinages. The filter chips above the list let you read any one group on its own.
Because Meta does not publish it. On 2 August 2026 the nine letter pages of Meta's Glossary of Ad Terms were read in full, 328,851 characters, and the phrase engagement rate appears zero times in any casing. It is also absent from the metric list in Meta's Instagram user insights API reference, which documents accounts engaged, total interactions, reach, views, saves, shares and replies, but no rate. So engagement rate is a calculation the industry performs, not a number Instagram reports, and the divisor is the argument: some tools divide interactions by followers, others by reach, others by impressions. That is why two dashboards can describe the same post differently and both be right. The engagement rate calculator shows each definition side by side.
No. Search Instagram's own Help Center for shadowban and you get what we got in August 2026: twenty-five results, topped by articles on the dissemination of terrorist content and accepted payment methods in Brazil. Not one is about the concept. The word also appears zero times in Meta's Glossary of Ad Terms. That does not prove reach never drops. Instagram does publish rules about what is eligible for recommendations, and it does limit content that breaks its policies. It means the word itself, and the mechanism people describe with it, is community vocabulary rather than a documented setting. Of the five big glossaries counted on this page, two flag shadowban as unofficial, and shadowban is the only term either of them flags at all.
Because Instagram says channel. Searching the Instagram Help Center for broadcast channel in August 2026 returned twenty-five results whose titles read Create a channel on Instagram, Channels, Join a channel on Instagram, What moderators of channels on Instagram can do and Privacy and safety in Instagram channels. Not one article uses the phrase broadcast channel. The community name is not wrong as speech, but it costs you time: search the Help Center for it and you won't land on the article that answers your question. That is the practical reason the glossary tags a source, not only a definition. Knowing Meta's word for a thing is what makes Meta's documentation findable.
They describe the same action from two directions. Private reply is Meta's documented name: the comment moderation page of the Instagram Platform documentation describes sending a message to the person who commented on your media post. Comment-to-DM is the name the software industry gave the product built on top of it, usually meaning a private reply fired automatically when a comment contains a chosen word. So the mechanism is Meta's and the phrase is a vendor coinage, which is why the glossary tags them differently. It matters when you are reading documentation or a policy page, because searching Meta for comment-to-DM finds nothing. The comment-to-DM caption generator covers how the trigger word and the post work together.
They do not. In August 2026 we counted the entries in the five most popular glossaries with countable lists: CreatorFlow with 82 terms, RateMyInsta with 137, Hashmeta with 208, Brandwatch with 110 and HubSpot with 184. That is 721 entries. Across all of them, exactly two entries say anything about whether a term is Meta's own vocabulary, and both are shadowban. No page carries a source label on its entries, and no page says when its definitions were last matched to Meta's wording. A sixth page, Strike Social's Instagram advertising handbook, sits outside the totals because its terms are bold phrases in prose rather than a countable list. It carries three links to Meta documentation, more than any page in the table.
No. The definitions are a fixed list written by hand, and the tool above is a search and filter over that list. Nothing you type is sent anywhere, no request leaves your browser, and the same search always returns the same rows. That is deliberate for a reference page: a definition that changes between visits is not a definition. Every entry was matched against a named Meta document or, for community terms and vendor coinages, confirmed absent from Meta's vocabulary. The labels are dated August 2026, on the line under the list, so you can judge how stale they are.
It is the period in which your app may reply to someone who messaged you. Meta's Instagram messaging documentation states that an app has 24 hours to respond to a user's message under standard messaging. Meta also documents a human agent feature, which allows a human agent to respond using the human_agent tag within 7 days of a user's message. Both figures are Meta's own, which is why the glossary tags the messaging window under developer docs rather than treating it as folklore. The practical effect is that a follow-up planned for day three is a different kind of message from a reply sent the same afternoon. The DM sequence generator works through what fits inside each window.
Every tag carries the date it was checked, and that date is printed under the search box rather than buried in a footer. The current check is 2 August 2026. Instagram renames features and retires metrics often enough that this matters: Meta's Instagram user insights reference marks impressions as retired from Graph API v22.0 in favour of views, and a glossary that missed it would hand you a metric your reports no longer contain. When a term moves between labels, the label changes and the date moves with it. If you find a tag that no longer matches its source, the source named on the tag is the one to check first.
