How does the keyword extraction work?

The tool tokenises your text into individual words, removes a list of common English stop words (the, a, is, in, and, etc.), and filters out words shorter than 3 characters. The remaining words are converted to hashtags. Multi-word keywords are not extracted — each hashtag represents a single meaningful word from your text.

What is the Twitter character limit for hashtags?

Twitter/X has a 280-character limit per tweet. This tool shows the total character count of the generated hashtag string so you can see exactly how much of your character budget the hashtags consume. Subtract from 280 to know how many characters remain for your actual tweet text.

What is the Instagram hashtag character limit?

Instagram captions have a 2,200-character limit. Hashtags within a caption count toward this limit. With 30 hashtags of average 15 characters each, that is 450 characters — leaving 1,750 for your caption text. Instagram also has a limit of 30 hashtags per post (though the recommended number is now 3–5).

Should I use CamelCase or lowercase hashtags?

CamelCase (#ContentMarketing) is preferred for accessibility — screen readers parse it as separate words. Lowercase (#contentmarketing) is more compact. Both are algorithmically equivalent on all major platforms. Use CamelCase for professional and accessible content; lowercase for casual, character-limited posts.

Hashtag Strategy Guide

How to use hashtags effectively on each platform

Hashtags work differently on every platform. The optimal number, format, and source of hashtags varies widely between Twitter/X, Instagram, LinkedIn, and TikTok. Using the wrong strategy — especially too many hashtags in the wrong place — actively suppresses reach on some platforms.

Twitter/X: 1–2 hashtags max

Twitter research shows that tweets with 1-2 hashtags get 21% more engagement than those with more. Tweets with 3+ hashtags see engagement drop. Twitter's 280-character limit makes hashtag bloat expensive. Use hashtags for discoverability on trending topics, not as keyword stuffing.

Instagram: 3–5 targeted hashtags

Instagram changed its algorithm in 2022. Meta officially recommends 3–5 relevant hashtags per post. The era of 30-hashtag dumps is over — Instagram confirmed these do not boost reach and may suppress it. Focus on mid-size, niche hashtags (100K–1M posts) over massive generic ones.

LinkedIn: 3 hashtags, first comment

LinkedIn recommends 3 hashtags per post. More than 5 can make a post look spammy. Unlike Instagram, LinkedIn hashtags work best when they are broad professional categories (e.g., #Marketing, #Leadership, #SEO) rather than highly niche tags. Post hashtags in the content, not a comment.

TikTok: mix of niche and broad

TikTok hashtags help the algorithm categorise content for the For You page. Use 3–5 hashtags: 1-2 broad (#SEO, #Marketing), 1-2 niche (#SeoTips, #ContentStrategy), and 1 trending if relevant. TikTok penalises excessive hashtag use but rewards accurate categorical tagging.

CamelCase vs lowercase hashtags

CamelCase (#ContentMarketing) is more readable and screen-reader accessible. Lowercase (#contentmarketing) is smaller and less visual but equally functional algorithmically. Screen readers for visually impaired users read CamelCase correctly as separate words; they read lowercase hashtags as a single run-on word. CamelCase is the accessibility-preferred format.

Hashtag research: find the right size

On Instagram, hashtag size affects reach. Under 10K posts: very niche, small audience but easier to rank. 10K–500K: sweet spot for mid-size accounts. 500K–5M: competitive, good for reach if your account is large. Over 5M: effectively useless for discovery for accounts under 100K followers.

Pro Tips

Check hashtag character count

This tool shows total character counts for generated hashtag strings. Twitter's 280-character limit includes hashtags — a string of 10 hashtags averaging 15 chars each costs you 150 characters. Always factor hashtag length into your composition budget.

Remove brand names before generating

Competitor brand names and proper nouns often appear as top keywords. Before using generated hashtags, check each one — accidentally hashtagging a competitor's brand name on your post is a common embarrassing mistake that this tool cannot guard against automatically.

Edit the keyword list before copying

The generated hashtags are a starting point, not a final answer. Remove irrelevant ones, add your brand hashtag manually, and reorder by priority. The best hashtag strategy is always a curated mix of generated and manually-chosen tags.
