Question 1

How long can a single hashtag be?

Accepted Answer

Most platforms allow up to 100 characters per tag, but tags over ~30 characters are rarely searched and dilute reach. Our tool flags anything over 24.

Question 2

How many hashtags can I use on Instagram?

Accepted Answer

Up to 30 per post and 10 per Story. Reels follow the post rule (30). The current best-practice mix is 3-5 high-relevance tags.

Question 3

TikTok hashtag rules?

Accepted Answer

No hard tag count, but the entire caption (including tags) caps at 2,200 characters. Aim for 3-5 tags mixing one trending tag with niche terms.

Question 4

Does YouTube use hashtags?

Accepted Answer

Yes — first three hashtags in a description appear above the title. Maximum 60 per video; over 15 disables them entirely.

Question 5

What characters are allowed in a hashtag?

Accepted Answer

Letters, numbers, and underscores. Spaces, punctuation, and emojis break a tag. Our tool warns you about invalid characters in real time.

Question 6

Are there banned or shadow-banned tags?

Accepted Answer

Platforms keep undisclosed lists of restricted tags. We maintain a community-sourced list and flag tags suspected of being limited.

Question 7

How is character count different from word count?

Accepted Answer

A tag is one "word" but its character count drives discoverability — short, focused tags rank better than long compound ones.

Question 8

Can I paste a whole caption to scan all tags at once?

Accepted Answer

Yes. Paste any text and the tool extracts all "#tag" tokens, counting characters per tag and total tag-character usage.
