What Is Hashtag Generator?
The Hashtag Generator creates relevant, targeted hashtag sets from your topic or keywords. It analyzes your input against a database of popular hashtags across major categories — marketing, business, technology, fitness, food, travel, fashion, photography, education, and real estate — and scores each hashtag for relevance. The tool generates a mix of popular high-volume tags for broad reach and niche-specific tags for targeted discoverability. It also creates custom compound hashtags from your input words. You can adjust the output from 5 to 30 hashtags to match platform best practices. Hashtags remain one of the most effective organic discovery mechanisms on Instagram, TikTok, and Twitter.

Technical Guide
Hashtags function differently across platforms. Instagram: up to 30 per post, 5-15 recommended, used for Explore page discovery. TikTok: 3-5 recommended, used for FYP algorithm categorization. Twitter/X: 1-3 recommended, more than 2 can reduce engagement. LinkedIn: 3-5 recommended, used for feed algorithm targeting. Our generator uses keyword matching and category scoring to find relevant hashtags. It assigns higher scores to exact keyword matches and partial matches, then sorts by relevance score. The tool generates three types: exact category matches (highest relevance), related category tags (medium relevance), and custom compound tags from your input (unique to your content). Best practice is to mix popular hashtags (100K+ posts) with medium (10K-100K) and niche (under 10K) for optimal discoverability.
