Các câu hỏi thường gặp

›How long should an SEO meta description be?

Roughly 155 characters. Google may truncate longer descriptions in search results.

›What's the Twitter/X character limit?

280 characters for free accounts. URLs count as 23 characters regardless of actual length.

›Does it count emoji as one character?

Most do, but combined emoji (e.g. with skin-tone modifiers) count as multiple JavaScript code units. We show both for safety.

›Is my text sent anywhere?

No — counting happens entirely in your browser.

›Is the counter free?

Yes — fully free, no signup.
