Write keyword-optimized channel description

A platform description (or bio) is the short text that tells both humans and the platform's algorithm who you are, what you do, and who for. Two audiences read it at once: a person deciding in seconds, and a ranking algorithm deciding what searches you appear in.

It's prime indexed real estate most competitors fumble with vague slogans. The first line does the heaviest lifting — it's what previews show and what the algorithm weighs most. Getting your what you do and for whom into that first line, naturally, is one of the highest-return edits in SEO.

How to do it

1. 1
   This is your YouTube channel description.

   Shows on your channel's About tab and feeds YouTube + Google search for your channel. Limits: Up to 1,000 characters, but only the first ~100–150 show before 'more'. YouTube's search indexes this heavily.
2. 2
   Lead with your primary topic — naturally

   Open with what you do and where, in words a customer would search. 'Family-owned fence installation in Boulder' beats 'Welcome!' The first 1–2 lines carry the most weight and are often all a preview shows.
3. 3
   Answer who/what/for-whom in 2 seconds

   If a first-timer can't answer all three from your description alone, rewrite it. Specifics beat adjectives: '15 years installing cedar and vinyl fences' tells more than 'trusted quality experts.'
4. 4
   Write for humans — Google will follow

   Draft it as if explaining to a neighbor, then be specific about what you do, who you serve, and where. If a phrase feels jammed in, cut it — stuffing gets penalized and humans bounce.
5. 5
   What matters most on THIS platform

   YouTube is the world's #2 search engine. Put your main topic and what your videos help with in the first sentence — it directly affects whether your channel surfaces in YouTube search and suggested channels. Add your upload schedule and 2–3 links at the end.
