How many hashtags should I use?

Do hashtags still work in 2025?

What it does

Suggests hashtags based on content, industry and platform. Balances between popular and niche hashtags.

Your hashtags are either too popular to be seen or too obscure to be found

Hashtags are still one of the most important mechanisms for organic reach on Instagram, LinkedIn and TikTok. But most people use either the most popular hashtags (where the post drowns among millions of others) or random hashtags that nobody searches for. The optimal strategy is a mix of popular, medium and niche hashtags — but finding this mix manually for each post is time-consuming and requires research.

Too popular hashtags (#love, #inspo, #business) mean your post disappears in seconds among millions of other posts — you get no lasting visibility
Too obscure hashtags that nobody searches for give zero extra reach — you waste hashtag slots on words that generate no traffic
No platform adaptation — Instagram rewards 20-30 hashtags, LinkedIn works best with 3-5, and TikTok has completely different rules — but most use the same strategy everywhere
Manual hashtag research takes 15-30 minutes per post — you need to search, check volume, evaluate relevance and find the right mix for each individual post

AI-generated hashtag sets with optimal mix of popular, medium and niche hashtags — adapted to platform and content

Hashtag Gen analyzes your content and generates an optimal set of hashtags balanced between popular (for visibility), medium (for competitiveness) and niche hashtags (for targeted reach). The tool adapts the number and style to the platform — 25-30 for Instagram, 3-5 for LinkedIn, 4-6 for TikTok — so you get maximum reach on each channel.

Balanced mix: 30% popular hashtags for visibility, 40% medium for competitiveness, 30% niche for targeted reach — the proven formula for organic growth
Platform adaptation: Instagram gets 25-30 hashtags, LinkedIn gets 3-5 professional ones, TikTok gets 4-6 trend-based — optimal number and style for each platform
Content analysis: the AI analyzes the text and image in your post and chooses hashtags that match the specific content — not generic industry hashtags
Trend integration: the tool identifies trending hashtags relevant to your content and includes them to leverage the moment momentum

Features

Platform selector: choose between Instagram, LinkedIn, TikTok, Twitter or Facebook — the tool adapts number, style and type of hashtags to the platform algorithm and norms
Volume indicator: see estimated volume for each hashtag — high (1M+), medium (100K-1M) or niche (under 100K) — so you understand the mix and can adjust
Copy button: copy all hashtags with one click in the correct format for the platform — with spaces for Instagram, comma-separated for other platforms
Hashtag groups: save and reuse hashtag sets for different content types — e.g. "product photos", "behind-the-scenes", "tips and advice" — for consistent strategy

How it works

Describe the content of your post or paste the text — the tool analyzes the topic, tone and audience to find relevant hashtags
Choose platform (Instagram, LinkedIn, TikTok) and any preferences for industry, language or specific hashtags you want to include
Get a complete hashtag set with optimal mix of popular, medium and niche hashtags — ready to copy and paste into the post

Use cases

Instagram content creators publishing daily who need unique, relevant hashtag sets for each post without spending 15 minutes on manual research
LinkedIn marketers who need the 3-5 most effective professional hashtags to maximize reach on professional posts
Social media agencies managing multiple accounts who need to produce hundreds of unique hashtag sets efficiently without reusing the same hashtags

Why use Hashtag Gen?

Hashtags are free reach — they let your content be discovered by people who do not follow you yet. But only when you use the right hashtags in the right mix. Hashtag Gen does this optimization automatically for each post, so you get maximum reach without manual research.

The balanced mix of popular, medium and niche hashtags is the key. Popular hashtags give instant visibility (but short duration), medium give competitiveness (the post can reach the top), and niche hashtags give targeted reach to exactly your audience.

For teams and agencies the tool eliminates inconsistency. Instead of each team member choosing hashtags based on gut feeling, all posts get a data-driven, optimized hashtag strategy that matches the content and platform.
