Hashtag Generator
Generate relevant hashtags for any topic
How to use
Enter your topic or keyword, select one or more categories that match your content, and choose how many hashtags to generate. Topic-derived hashtags appear highlighted and are prioritized. Copy the entire set with one click and paste into your social media post.
Examples
Instagram food post
Enter 'homemade pasta' and select the Food category. Generate 20-25 hashtags mixing your topic (#homemadepasta, #pasta) with popular food tags (#foodie, #cooking, #recipe).
Tech content on X
Enter 'React hooks' and select Tech. Generate 5-10 focused hashtags since X posts perform better with fewer hashtags. Use #react, #reacthooks, #webdev, #javascript.
Travel photography
Select both Travel and Photography categories for a broader mix. Topic hashtags like #travelphotography combine with general tags like #wanderlust and #landscape.
Frequently asked questions
How many hashtags should I use?
It depends on the platform. Instagram allows up to 30 but 5-15 focused hashtags tend to perform best. X works best with 1-3 hashtags. LinkedIn recommends 3-5. TikTok performs well with 3-5 relevant hashtags plus trending ones.
Should I use the same hashtags on every post?
No. Varying your hashtags prevents your content from being flagged as spam. Rotate between sets and mix popular broad hashtags with niche specific ones. This tool generates different combinations each time.
What is the difference between topic and category hashtags?
Topic hashtags (highlighted in orange) are derived directly from your input text. Category hashtags come from curated lists of popular tags in each niche. The best strategy combines both: topic-specific tags for relevance and category tags for discoverability.
Do hashtags still work on social media?
Yes, but their role has shifted. On Instagram and TikTok, the algorithm is more important than hashtags for reach. However, hashtags still help with discoverability in search results and niche communities. On LinkedIn and X, they remain effective for joining conversations.
Should I put hashtags in my caption or comments?
On Instagram, both approaches work. Putting hashtags in a first comment keeps captions clean without affecting reach. On X and LinkedIn, include them inline in the post. On TikTok, they must be in the caption.
