# Free hashtag finder and counter by topic

Look up hashtags by topic from lists 1Post curates by hand, copy them in one click, and count the hashtags already in a post.

Type a topic such as fitness, travel or small business to get a hand-curated list of hashtags for it. Pick the ones that fit, copy them in one click, or paste a post to count the hashtags it already has. The lists are ours, with no reach figures attached.

## How it works

The finder matches your words to topics by name and by related words, then lists that topic's tags. Lists are curated by hand and grouped by what a post is about; no popularity number is shown because none was measured.

Paste a finished post into the counter to see how many distinct hashtags it uses, in order of first use.

> It runs in your browser. Nothing you type or choose is uploaded, and the page works without an account. To publish what you made, [start a trial](https://get1post.com/signup.md) and open it in the composer.

## Questions

**How many hashtags should a post have?**

It depends on the network and changes over time, so no number is promised here. Choose the few that describe the post and check your network's current advice.

**Where do the lists come from?**

They are written by hand for 1Post and grouped by topic. They are starting points, not rankings.

**Why no popularity numbers?**

The networks do not publish them in a form a free tool can read, and we do not invent numbers. The finder gives lists to choose from, and you judge fit.
