Web keywords vs YouTube keywords
Web searchers read. YouTube searchers watch. The intent words shift: "how to fix" beats "best fix", "explained" beats "definition", "tutorial" beats "guide". A purpose-built YouTube SEO strategist thinks in video intent first.
Stop borrowing your blog's keywords for your video titles. PNX is a free agentic SEO tool built for creators, founders and SEO teams who need real answers — fast — without paying $99/month for legacy platforms. This guide breaks down everything about YouTube SEO keywords in plain English, with a comparison table, internal links to our free tools, and a one-click way to try it yourself.
Where to place YouTube SEO keywords
- Title: primary keyword in first 40 chars
- First line of description: primary + secondary
- Tags: 1 broad + 5 specific + 2 misspellings
- Filename of uploaded MP4: yes, this still works
- Spoken in the first 30 seconds: helps YouTube's auto-captions match
- Pinned comment: 1–2 long-tail variations
