Telegram channel owner's glossary

The words you meet in channel statistics, advertising and settings, briefly and with formulas.

Reachpost views: How many times a post was viewed. Telegram shows a view counter on each post; reach of an ad post is usually checked 24 hours after it goes out.

Slotplacement format: What exactly is sold: for example, a post that stays on top of the feed for 24 hours, or a pinned post. A slot has a format and a price.
Escrow: An arrangement where an intermediary holds the advertiser's money and releases it to the channel owner only after the post goes out.
Cross-promotionshout-for-shout: A no-money ad swap between channels: each one publishes a post about the other. Cross-promotion in Telegram →

Evergreen queue: A set of posts that don't go stale and are published in rotation to fill empty schedule slots.
