Where to Announce a New YouTube Video#

The best places to promote a YouTube video are the ones where people already follow you, because they need the least convincing to click. For most creators that means an Instagram feed post, a vertical post on Reels, TikTok or Stories, a LinkedIn update for professional topics, a post on X, and your email list if you have one.

Each place wants a slightly different post. The Announcement Maker handles that by tying the copy to the format you pick, so one video can give you a version for each format:

A still image works on a feed, but short vertical video is what Reels and TikTok are built around. For those two, a clip cut from the video itself often fits better, and Shorts Maker produces vertical clips from your upload. Use the announcement post alongside the clip, not instead of it.

Post Sizes for Instagram, TikTok and LinkedIn#

Only some platforms publish exact image sizes, and several of the figures you see quoted online come from ad specs or third-party guides. These are the ones we could confirm on the platforms' own help and developer pages.

For Reels and Stories, 1080×1920 at 9:16 is the commonly used size, but we could not confirm it on an official Instagram page, so treat it as a working default rather than a rule. Instagram resizes larger feed photos down to 1080 pixels wide, so uploading bigger gains nothing there.

How to Write a Hook That Drives Clicks to YouTube#

The hook is the first line people see before they decide to keep reading. It should state the payoff of the video, not describe the video. "I tested five budget mics so you don't have to" gives a reason to click. "My new video about microphones is out" does not.

Keep the promise consistent with your title and thumbnail. If the post oversells, people click, feel misled and leave early, which does your video no favors. Then close with one clear action and the link, or "link in bio" where links in captions don't work.

Used as a social media post generator, the tool follows the same shape: a one or two sentence hook, a short summary ending in your chosen call to action, and five to eight hashtags. Treat it as a first draft and rewrite the hook in your own voice if it doesn't sound like you.

Announce Once or Repost Over a Week#

A single post only reaches the followers who happen to open the app that day. Spreading a YouTube video launch across a few days reaches more of them, as long as each post gives a new reason to look. Reposting the identical graphic three times reads as spam; three different angles on the same video do not.

1. 1Launch day: the main announcement with the hook and the link, on every platform you use.
2. 2A few days later: a different angle, such as the most surprising moment, a quote or a vertical clip.
3. 3End of the week: a reply to a good comment, a behind-the-scenes note or a question to your audience.

There is no published data on the ideal number of posts, so use your own numbers. Watch where views come from in YouTube Analytics and keep the platforms that send people. For cross platform promotion beyond this video, put a subscribe link in your bios, and if you run a contest, the Giveaway Picker handles the draw from your comments.
