TikTok rewards short vertical video that earns attention in its first seconds. This page covers when and how often to post on TikTok, how to write the hook and caption, how many hashtags to use, and what Convia Pro does for you when it writes and schedules TikTok posts.

When to post on TikTok

Convia schedules TikTok posts at 12pm, 6pm and 9pm in your workspace time zone when you have not set your own times. These are a starting point. To change them, go to Channels, click Edit beside When posts go out, open Advanced and click Choose my own times. See Calendar & scheduling.

How often to post on TikTok

Three to five short videos a week is a reasonable starting point for a weekly show. A steady rhythm you can hold for three months is worth more than a burst you cannot, so raise the pace once it feels easy. Convia starts every channel at 3 posts a week, which you can change under Posts per week.

Spread clips from one episode over several weeks rather than posting them on one day.

Hooks that hold TikTok viewers

  • The first 3 seconds decide whether people keep watching. Open on the most interesting moment, not an introduction.
  • Create a reason to keep watching. A question or an unfinished thought pulls viewers to the end.
  • Use trending sounds where they fit your video.
  • Reply to comments right after posting.
  • End with a prompt to engage: invite comments, Duets or Stitches.

TikTok captions and hashtags

  • TikTok captions can be up to 2,200 characters, but the video carries the post. Keep the caption casual and short.
  • Use 4 to 7 hashtags at the end of the caption. Favour niche, specific tags over broad ones, with at most two broad or trending tags.
  • Links in TikTok captions cannot be clicked, so point people to the link in your profile instead.

TikTok video format

Make videos vertical, 9:16. MP4 with the H.264 codec gives the best compatibility. TikTok photo posts take JPEG or WebP only, at most 1,080 × 1,920 pixels. For every file limit and the settings TikTok requires on each post, see Posting rules for each platform.

How Convia writes your TikTok posts

Convia writes TikTok captions from your Platform instructions for TikTok (Brand Brain → Platform instructions) and your Brand Brain: your brand characteristics, ideal customer and content rules. When a post sends people somewhere, the ask points to the link in your profile.

Where your brand and this guidance disagree, Convia follows your Brand Brain. A rule for every platform, such as never using emojis, goes in Content Rules under Brand Brain → Voice & Tone. A change for TikTok alone goes in TikTok's Platform instructions, which come with Grow and up. See How AI uses your brand.
