Generate, score and pick YouTube titles and thumbnail text before publishing. Writes 10 title candidates across proven angles, scores each with a transparent rubric (length, keyword position, specificity, curiosity gap, promise match), pairs each winner with 2 to 4 word thumbnail text that does not repeat the title, and plans an A/B test. Use for "YouTube title", "tiêu đề YouTube", "đặt tên video", "thumbnail text", "chữ trên thumbnail", CTR, click-through rate, "video ít view", or A/B testing titles.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

YouTube Title Lab

The title and thumbnail decide whether anyone sees the video. Treat them as a small experiment, not a guess.

Step 1. Inputs

Ask for: what happens in the video (the actual payoff), the viewer it is for, the main search phrase if any, the channel language, and 2 or 3 titles from competing videos that performed well. If the user has none, work from the payoff alone.

Step 2. Ten candidates, five angles

Write two titles for each angle:

  1. Result: the concrete outcome with a number.
  2. Process: how something is made or done, in the viewer's words.
  3. Contrast: before and after, cheap and expensive, beginner and pro.
  4. Question or mystery: a gap the video closes.
  5. Search: the main phrase first, plain and exact.

Rules: the title must be true to the video. No clickbait the video does not pay off, because it raises early drop-off and hurts reach.

Step 3. Score

Save the candidates one per line and run:

python scripts/score_titles.py titles.txt --keyword "woodworking" --lang en

The rubric (0 to 100) rewards: 35 to 60 characters, keyword in the first half, a digit or specific noun, a curiosity or contrast word, and no ALL CAPS shouting. It penalizes: over 70 characters (cut off on mobile), vague words, and more than one exclamation mark. The score is a filter, not the decision; read the top 3 yourself.

Step 4. Thumbnail text

For each of the top 3 titles write thumbnail text of 2 to 4 words that adds information the title does not have (a number, a reaction, a label). Never repeat the title on the thumbnail.

Step 5. Test plan

Recommend testing the top 2 or 3 title and thumbnail pairs with YouTube's built-in "Test and compare" when available, or by swapping after 48 hours. Compare click-through rate only between periods with similar impressions, and keep the winner for at least 7 days.

Output

A table: title, angle, score, thumbnail text, notes. Then the recommended pair and the test plan.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
