How to use this Mastodon hashtag generator
Three steps, under a minute, no login required.
-
Describe your post
Add a sentence about what you’re posting. “A sunrise photo from a hike in the Scottish Highlands” works well.
-
Choose how many
Pick up to 20 tags. On Mastodon, three to five well-chosen tags usually beat a long list.
-
Copy and post
Click any tag to copy it, then add it to your post. Put tags at the end, or work them into a sentence.
Why hashtags matter more on Mastodon
Mastodon has no algorithm deciding who sees your posts. Hashtags are one of the main ways new people find you.
Search
Hashtags are searchable, so a clear tag puts your post in front of people looking for that topic.
Follow
People can follow a hashtag, and posts with it show up in their home feed, even from accounts they don’t follow.
Feature
You can feature a few hashtags on your profile, so visitors can browse your posts by topic.
Tips for Mastodon hashtags that get found
A few good habits go a long way.
-
Use CamelCase
Write #IndieDev, not #indiedev. Screen readers read each word, and everyone can read it faster.
-
Be descriptive
Choose tags that say what the post is about, like #Photography or #ClimateAction, over vague ones.
-
Keep it to a few
Three to five relevant tags is plenty. Long tag lists can look spammy to Mastodon communities.
-
Check what people use
Search a tag before you use it. If people already follow it, your post reaches more of them.
