Use Cases

Frequently Asked Questions

How many hashtags should I use on Instagram?

Instagram allows up to 30 hashtags per post, but research and Instagram's own guidance suggests using 3-5 highly relevant hashtags for optimal reach. Quality and relevance matter more than quantity.

What is the hashtag limit on LinkedIn?

LinkedIn has no hard limit on hashtags, but recommends using 3-5 relevant hashtags per post. Using more than 5 can make your post look spammy and may reduce engagement.

Can I paste a full caption with text and hashtags?

Yes. Paste any text — the tool automatically detects and counts all words starting with # as hashtags, ignoring regular text.

Does this tool detect hashtags in different languages?

Yes. The counter detects any word starting with the # symbol regardless of language, including hashtags in Arabic, Japanese, Korean, and other scripts.

How many hashtags does TikTok allow?

TikTok allows hashtags within the 4,000-character caption limit. However, hashtags count toward this character limit, so keep them concise. Using 3-5 relevant hashtags is common practice.

Can using too many hashtags hurt my reach?

Yes. On Instagram, using all 30 hashtags or using irrelevant/banned hashtags can trigger shadowbanning, where your posts are hidden from hashtag searches. On X/Twitter, more than 2 hashtags can decrease engagement by 17%.

What are banned hashtags?

Banned hashtags are tags that Instagram has restricted because they were associated with spam or content violations. Using banned hashtags can reduce your post visibility. The list changes frequently — search for updated lists before using unfamiliar tags.

Is the hashtag counter free?

Yes. The tool is completely free with no registration, no limits on usage, and no data collection. All counting happens in your browser.

How many hashtags should I use on TikTok?

TikTok works best with 3–5 highly relevant hashtags. The platform allows hashtags within the 4,000-character caption limit, but stuffing 30 tags into a TikTok caption looks spammy and won't increase reach. Pair 1 broad trending tag with 2–4 niche tags for the best balance.

Is there a hashtag counter for Facebook?

Yes — this tool counts hashtags in Facebook captions the same way it does for Instagram or X. Facebook has no platform limit, but research shows 2–3 hashtags per post performs best. More than that adds visual noise without increasing reach.

Can this tool extract hashtags from a YouTube description?

Yes. Paste a YouTube description and the tool extracts every word starting with #. Note: YouTube only displays the first 3 hashtags above a video title, so put your most important hashtags first in the description.

What's the difference between hashtag counting and hashtag generating?

Hashtag counting (this tool) tells you how many tags are in a caption you already wrote. Hashtag generators suggest new tags based on a topic. Both are useful — count first to stay within limits, then generate variants if you need more relevant ones.

Does the tool detect hashtags with emojis or special characters?

Yes. Any token that starts with # and contains letters, numbers, underscores, or Unicode characters is detected. Hashtags with emojis don't work on most platforms (they break at the emoji), but the counter will still pick them up so you can see and remove them.
