Playbooks, teardowns and the occasional argument — everything we have learned helping creators grow across every major platform.
Shorts pay from a shared pool at a 45% creator share, not from watch-page ads at 55%. That structural difference explains everything about Shorts income.
LinkedIn has no documented hashtag limit, but three is where the convention settled. Here is why more looks amateur and what they actually do.
TikTok hashtags work as topic signals, not reach multipliers. Here is how many to use, why specific beats popular, and what actually drives the For You page.
Instagram allows 30 hashtags per post. Using all 30 is not a strategy. Here is the number that works, the mix, and where placement actually matters.
Every vertical feed draws its interface on top of your video. Here are the covered regions per platform, and how to design once for all of them.
An aspect ratio is a shape, not a size. Here is what each ratio is for, how to convert between them, and why cropping down beats scaling up.
