Who these guides are for
The reader we write for is running, or about to run, a long-form YouTube channel — on camera or faceless, either works — and wants to pick a niche from evidence rather than from a hunch or generic advice.
No data background is assumed. Every guide opens on a plain question: does this niche still have room for a newcomer, what is that channel actually earning from, which video is outperforming the rest of its own channel. Where a number is needed, we explain what the number means before leaning on it.
What order to read them in
- Find the niche first. Start with the Niche Hunter guide — how to surface the channels rising inside a topic, how to read the signals on a channel card, and how to rule out a niche that looks open but is already crowded.
- Keep what is worth watching. Save the niches and channels that stand out, group them, and let the system track their growth for you. A niche shows its real shape over a few weeks of watching, not in one evening.
- Compare against other tools. The tool comparison is blunt about what Viddar does, what it does not, and when a free tool already covers what you need.
Those three take you the full loop: from no niche idea at all to a short list of niches plus reference channels to follow. If you already have a niche in mind, invert the order — open the comparison first to sanity-check the niche against a second source, then come back to the Niche Hunter guide to see whether the channels growing inside it look anything like the channel you want to build.
The written guides and the videos cover the same ground. Watch the video when you want to see where a control sits on screen; read the article when you want the reasoning behind a threshold, or something you can search back through later.
What you need to follow along
A Viddar account covers every guide here. New accounts get three days on real data, no card required. Keep a notes file open too: most of the value in niche research comes from writing down why you ruled a niche out, so next month you are not weighing the same one from scratch.
Figures quoted in the guides are snapshots from the day of writing. What you see in the product will differ — the channels in the library are rescanned daily — so read the numbers as worked examples of the reasoning, and decide on the numbers in front of you.
If you get stuck
The Zalo support group answers fastest; the link sits in the footer of every page. Account, billing and personal-data questions go to the address on the contact page. And if a guide no longer matches the screen in front of you, tell us — when the product moves, the guide has to move with it.
