Can I post the same video on all three platforms?

Yes. Despite rumors, none of the platforms penalize content that also appears elsewhere. TikTok previously downranked videos with watermarks from other platforms, but cross-posting the same raw file is fine. Just don't upload with another platform's watermark.

Does posting time matter?

Moderately. Each platform has different peak hours depending on your audience's timezone. General guidelines: TikTok peaks in evenings (7–10 PM), YouTube Shorts performs steadily throughout the day, and Reels does best mid-morning and evening. Test and check your analytics.

Should I use hashtags?

On TikTok, 3–5 relevant hashtags help categorization. On YouTube Shorts, hashtags in the description help but aren't critical (YouTube's search algorithm reads your full description). On Reels, hashtags have become less important — Instagram's AI categorizes content regardless.

How often should I post?

Consistency matters more than frequency. For podcast clips: 3–5 clips per week per platform is a good starting point. If you're publishing a weekly podcast and pulling 5–10 clips per episode, that gives you enough content for daily posting across platforms.

Do I need separate accounts for each platform?

No. Use the same brand name across all three. Cross-platform consistency helps audiences find you. If you're a podcast, your clip accounts should match your podcast name.

Is vertical video (9:16) required?

For Shorts and TikTok, yes — horizontal content gets cropped and performs poorly. For Reels, 9:16 is strongly recommended but 4:5 and 1:1 also work in the feed. For podcast clips specifically, always use 9:16 with the speaker framed for vertical viewing.

What about LinkedIn and X (Twitter)?

LinkedIn native video and X video are growing but have different dynamics. LinkedIn favors longer clips (1–3 minutes) with professional context. X video autoplay works best under 60 seconds. Both are worth testing if your audience is there, but they're secondary to the big three for organic reach.
