Search by niche
A keyword, filters on subscriber and video counts, and two modes depending on how deep you want the analysis to go.
Tool review
Don't use ScanYTB before reading our review
It scans French YouTube channels and extracts everything their descriptions contain: tools, sponsors, affiliate links, domain names. Here's the use that genuinely pays off, what it really costs, and the limit nobody mentions.
What it does, concretely
You type a niche keyword. It finds the French channels covering the subject, opens their videos, and collects every link in the descriptions.
The database currently holds around 2,400 French channels, 180,000 videos analysed, 517,000 links extracted and 9,100 unique domain names. These aren't vanity numbers: they're the material you query on every search.
Reverse search
You paste a domain name and it shows you every video that mentions it, with the view count and the date.
Domain ranking
Which sites come up most often in a niche. It's a photograph of what that niche actually recommends.
Export
Every link, the unique links with their statistics, or just the root domain names.
The use that justifies the tool
You can use it to observe a niche. That's useful, but it isn't what makes it worth the detour.
The genuinely interesting use comes down to three moves. You scan your niche and collect the list of domain names cited in the descriptions. You export that list and check in bulk which ones are still registered. The ones that aren't can be bought back for about ten euros — and the link pointing at them, in a video description that people keep watching, is still there.
In other words: you don't have to ask a creator for a link, or pay for one. You buy the destination of a link that's already been placed, and sometimes seen by thousands of people a month. It's opportunism, but it's the good kind — the kind that consists of looking at what everyone already has in front of them.
Spotting a niche's tools
Which software, which courses, which services the channels in your sector actually recommend. Far more reliable than comparison articles, which are themselves written by affiliates.
WatchingFinding active affiliate programmes
An affiliate link in a description means the programme exists, that it accepts partners, and that it pays enough for someone to talk about it. Three pieces of information at once.
MonetisationIdentifying sponsors
Which brands pay in your niche, and on which channels. Useful if you're building an audience and want to know who to write to, with concrete examples to cite.
PartnershipsWatching a competitor
The reverse search tells you who talks about a given site, in which videos and for how many views. That's the part of its visibility no ordinary SEO tool sees.
IntelligenceWhat to know before paying
Three reservations, one of which the pages covering this technique never mention.
A link in a YouTube description passes no authority. These links carry the nofollow attribute, which tells search engines not to count them for ranking. If you buy a domain back expecting to move up the results, you'll be disappointed. What you actually get is traffic — people who click — and a presence on indexed pages. That's already a lot, but it isn't the same thing, and it's exactly the same reasoning as for a Chrome extension.
A free domain may be free for bad reasons. It may have been penalised, used for questionable practices, or carry a history you'll only discover months later. Check what it hosted before buying, and be wary of any whose history is unreadable.
A search costs a credit, so it deserves preparation. At €4.99 each, you don't fire off ten queries at random. Write your keyword, set your subscriber and video filters, pick your mode, then run it. The credit is returned if the search fails, not if it brings you useless results.
One last thing to keep in mind: the tool only covers French channels. That's a choice that makes it relevant on a French-speaking market and unusable if you're aiming internationally.
What it costs
- €4.99 per search
- One credit per search, no monthly subscription. You pay for what you use, which suits occasional use well — exploring a niche before committing to it, for instance.
- The credit returned if it fails
- A search that returns nothing isn't charged. That's a guarantee on execution, not on the quality of the results: a badly targeted search will complete and will cost you its credit.
- What gets added
- Around ten euros per domain bought back, if you follow the main lead. The total stays well below what a purchased link costs, provided the domain is worth it.
Common questions
Does a link in a YouTube description help my SEO?
Not directly, and it's important to know that before investing. These links are nofollow: they pass no authority in the sense SEO tools mean. What they do bring is real traffic and a presence on pages Google indexes. Many pages praising this technique leave that detail out.
How much does a search cost?
One credit at €4.99, no subscription. The credit is returned automatically if the search fails. Prepare your query before running it: the refund covers breakdowns, not bad targeting.
How do I check whether a domain is available?
By exporting the list of root domains, then running that list through a bulk availability checker. Most registrars offer one. You get the list of free ones in a few seconds.
Should I buy an expired domain?
Carefully. A free domain may have been penalised or used for questionable purposes. Look at what it hosted before, and walk away if the history is unreadable. For a first site, a fresh domain at eight euros is safer.
Does the tool cover channels outside France?
No, it's centred on French channels. That's what makes it relevant on that market and unsuited if you're aiming at an international audience.
Who is it genuinely useful for?
For people building niche sites and looking for links or affiliate programmes, and for people who want to know what a sector recommends before committing to it. Much less so for a creator who simply wants to grow their channel: it isn't a content analysis tool.
