How to Check Multiple YouTube Channels' Keywords for Competitor Research

Single-channel keyword extraction tells you what one channel does. Multi-channel keyword research tells you what the niche does — which phrases top channels consistently use, where there's differentiation, and what vocabulary YouTube already associates with your topic area. Here's the full workflow for auditing multiple channels' keywords at once.

Why Researching Multiple Channels Beats Researching One

Looking at one channel's keywords tells you that channel's strategy. Looking at 8-10 channels' keywords reveals the niche's vocabulary — the terms that multiple successful channels have independently decided describe this content area.

That consensus matters because it tells you which phrases YouTube already uses to categorize channels in your space. When multiple high-performing channels in a niche use "meal prep for beginners," that phrase isn't just their choice — it's become part of how YouTube understands that niche. Adopting the same accurate vocabulary helps your channel get placed in the same category faster.

Single-channel keyword research also risks being skewed by one creator's idiosyncratic choices. A channel might have grown despite poorly chosen keywords, or they might have unusually strong keyword optimization that isn't representative of the niche. Multi-channel research smooths out these individual variations and surfaces the actual pattern.

Step-by-Step: Building a Multi-Channel Keyword Comparison

Set up a simple spreadsheet before you start. You'll use it to collect and organize the data as you go.

Columns to create:

• Channel name
• Channel URL
• Subscriber count (rough order of magnitude — helps weight the data)
• Full keyword list (paste the raw output here)
• Individual keyword phrases (one per column, or use a second sheet)

The collection process:

1. Identify 8-10 channels in your niche. Use YouTube search (channel tab), "related channels" sidebars, and your own knowledge of the space.
2. For each channel, paste the URL into the Channel Keywords Extractor and copy the full keyword output.
3. Paste the results into the spreadsheet. Do this for all channels before analyzing — get the data first, then interpret.
4. Note channels that return empty results (no keywords set). That's a data point too.

For 10 channels, this collection phase takes about 20-25 minutes total.

How to Find the Consensus Phrases That Matter Most

Once you have keyword lists from all channels, the analysis is about finding overlap. There are a few ways to do this depending on how comfortable you are with spreadsheets:

Manual scan: Read through all the keyword lists and highlight any phrase that appears in 3 or more channels. These are your consensus terms. This takes about 10 minutes for a 10-channel dataset.

Count column: If you split each channel's keywords into individual columns, you can use COUNTIF formulas to count how many channels include each phrase. Sort by frequency to surface the most common terms quickly.

Text concatenation: If you paste all keyword lists into a single column and use word frequency analysis, common phrases bubble up automatically. Free tools like word frequency counters can do this in seconds.

What you're looking for: phrases used by 3 or more channels (strong consensus signal), phrases used by 5 or more channels (very strong — probably the core vocabulary for this niche), and phrases used by only 1-2 channels (may be idiosyncratic choices or early-mover differentiators).

Turning the Research Into Your Own Keyword Set

After identifying the consensus vocabulary, build your own keyword set in three steps:

Include consensus phrases that accurately describe your channel. If a phrase appears across 5 of your top 10 comparison channels and accurately describes your content, include it. You're not copying — you're using the established vocabulary for your niche.

Add phrases that differentiate your specific angle. Where does your channel differ from the consensus? If most channels in your niche cover general cooking but yours specifically covers budget meal prep for college students, that specificity deserves its own phrases.

Leave out consensus phrases that don't fit. Just because a phrase appears across multiple successful channels doesn't mean it fits yours. Accuracy matters more than completeness. Including terms that don't match your actual content creates signal mismatch over time.

The result: a keyword set grounded in real niche vocabulary, personalized to your specific angle, and free from guesswork. Aim for 5-10 phrases total. For more on the structure, see our guide to how many channel keywords to use.

Frequently Asked Questions

Do I need any paid tools to do this research?

No. The Channel Keywords Extractor is free and requires no login. A free spreadsheet application (Google Sheets or Excel) handles the analysis. The whole workflow is zero-cost.

How many channels should I include in the comparison?

Five to ten is the practical range. Fewer than five doesn't give you enough data to identify patterns reliably. More than ten produces diminishing returns — patterns become clear by around seven to eight channels in most niches.

What do I do if most channels haven't set any keywords?

If the majority of top channels in your niche have empty keyword fields, that's an opportunity — the competitive bar on channel-level SEO is low. Look at channels in adjacent niches for vocabulary reference, and use YouTube search autocomplete to identify the phrases real viewers use to search your topic.

Should I update this research regularly?

Once per year or when you're doing a channel rebrand. Channel keyword vocabularies change slowly. An annual check to see if the niche's consensus has shifted is usually sufficient. If a major new sub-niche emerges in your topic area, that might warrant an earlier update.
