What Is Hashtag Counter?
The Hashtag Counter analyzes any text to count, categorize, and evaluate hashtags. It goes beyond simple counting — identifying unique vs. duplicate hashtags, checking counts against each platform's recommended limits (Instagram 30, Twitter 3, LinkedIn 5, TikTok 5), and providing length analysis for the longest, shortest, and average hashtag. This is essential for social media managers who need to ensure their posts don't exceed platform limits and aren't wasting space with duplicate tags.
Why Use Our Hashtag Counter?
- Instant total and unique hashtag counts
- Duplicate hashtag detection
- Platform-specific limit checking for Instagram, Twitter, LinkedIn, and TikTok
- Length analysis showing average, longest, and shortest hashtags

Technical Guide
The tool uses regex pattern matching to identify hashtags — sequences beginning with # followed by word characters and Unicode characters. It performs case-insensitive deduplication to identify truly unique hashtags. Platform limits: Instagram allows 30 hashtags (5-15 recommended), Twitter best practices suggest 1-3, LinkedIn recommends 3-5, and TikTok works best with 3-5. Exceeding these limits doesn't always cause errors but can reduce reach or trigger spam filters. The tool also analyzes hashtag length — excessively long hashtags (20+ characters) are harder to read and less likely to be searched, while very short ones (under 5 characters) may be too generic.
