SEO Studio Tools — free YouTube SEO tools backed by real trending data

Twelve free tools for YouTube creators, plus a public index of the tags, hashtags and title patterns of the videos trending in eight countries, rebuilt every day from the official YouTube Data API.

The difference from most tools in this category is evidence. When a tag is suggested here you are told how many trending videos in the country you picked actually use it, and what those videos average in views. When there is no evidence for a suggestion it is labelled untested rather than given an invented score. Nothing here reports a YouTube search volume, because YouTube does not publish one.

Nothing needs an account. There is no sign-up, no credit card, no free trial and no paid tier — every tool and the whole index are open to anyone.

What it does not do: it cannot see your channel analytics, it cannot promise rankings, and it does not sell backlinks or views. For a wider view of the market, including the tools it does not try to replace, read the guide to YouTube SEO tools.
