Two settings, two different jobs
Mastodon gives you separate controls for your network lists and for search-engine indexing. They answer different questions, and neither one is a privacy wall around your posts.
- Network-list visibility controls whether visitors can see who you follow and who follows you.
- Search indexing preference controls whether public pages carry a signal asking search engines not to index them.

Opting out of search-engine indexing adds a noindex flag to public profile and status pages. Source
What noindex actually does
A noindex flag is a request, not a password. It tells compliant search engines not to add the page to their indexes. It does not block a logged-out visitor who already has the link, and it does not change the audience of a post. Post audience is a separate matter, covered in the post-visibility guide rather than repeated here.
| Reader question | Setting to review | What it changes | What it does not change |
|---|---|---|---|
| Can people see who I follow? | Network-list visibility | Display of following/follower lists | Who can read your posts |
| Will search engines list my profile? | Search indexing preference | A noindex signal on public pages | Direct access via a known link |
| Who sees a given post? | Post audience | The audience of that post | Your network lists or indexing |
Self-review checklist
- Decide whether your network lists should be publicly visible, then set the preference once and leave it.
- Decide whether you want public profile and status pages indexed, and set the indexing preference accordingly.
- Re-read your own posts’ audience settings; this is the control that actually limits who reads them.
- Open your profile logged out and note what a stranger can see.
- Check your known public handles elsewhere, because a Mastodon preference does not reach other platforms.
Where a username lookup helps
A Mastodon setting only covers Mastodon. If you want to review the public handles you already know you have used, TraceSeek checks 3,000+ platforms and states a 20-30 seconds scan time, with a free first scan. Public username matches are leads, not proof of ownership, and the app does not change platform settings or reveal private information. For a fuller inventory, see the guide to finding forgotten online accounts, and for how results are framed, read the methodology.
