Frequently Asked Questions

10 Q&As on YouTube title optimization.

Q1. What is the YouTube title character limit?

YouTube Studio hard limit is 100. Mobile feed truncates around 45, desktop home ~60, so 60 chars is the practical sweet spot.

Q2. How many emojis should I use?

Per VidIQ's 128M-video study, 0~2 is the sweet spot. Shorts titles with emojis gain +49% views; long-form sees smaller lift. 3+ reads spammy.

Q3. How are emojis counted?

We use Intl.Segmenter to count each grapheme as 1 character. Skin-tone (👨🏼) and ZWJ sequences (👨‍👩‍👧) are correctly 1 char, not 2-4 like many other counters report.

Q4. Are the 45/55/60/70 cutoffs exact?

YouTube truncates by pixel width, which varies with font size and viewport. These numbers are practical thresholds calibrated against YouTube Sans and mixed Korean/English content.

Q5. How is the CTR score calculated?

Starts at 50. Add length bonus (+15 for 30-60 chars, penalty above 70), emoji (+10 for 0-2, -15 for 5+), number (+8), power word (+8), question hook (+3). Subtract clickbait penalty (caps runs, repeated punctuation, hype words). Clamped 0-100.

Q6. Do I have to include a number?

Not mandatory, but "5 ways", "2026", "3 min" tend to boost CTR by 5-10%. Around 50% of top-performing videos use a number (VidIQ data).

Q7. How should I use A/B compare mode?

Enter two candidates, compare CTR scores and device previews side-by-side. A 10-point score gap is meaningful. Pick one, upload, then verify in YouTube Studio after 48 hours.

Q8. Why are CAPS runs flagged?

YouTube's guidelines treat 5+ consecutive caps as a spam signal. It may not directly demote your video but tends to increase bounce rate, which indirectly tanks ranking.

Q9. How does the share link work?

Clicking "Copy share link" copies a URL with your title, title B, and channel name as query parameters. Anyone opening that URL sees the same input pre-loaded.

Q10. Is my title stored anywhere?

Only in your browser's localStorage — nothing is sent to our servers. Your last input restores on revisit. For cross-device handoff, use the share link.
