Hashtags on Seldeo
Hashtags let you label a post by topic. Type them anywhere
in the caption with a leading # — #gardening,
#sunday_baking — and Seldeo picks them up when you
publish.
How to add them
Write them into the caption as part of the text. There is
no separate hashtag field; Sourdough, attempt four #baking #sourdough just works. A single post can carry up
to 30 hashtags — anything beyond that is ignored
rather than blocking the post.
How tags are normalized
Behind the scenes, Seldeo normalizes every tag so that spelling variants count as the same topic:
- Case is folded.
#Baking,#BAKING, and#bakingare the same tag. - Allowed characters are letters, numbers, and underscores. The tag ends at the first character that isn't one of those.
- Tags that don't survive normalization (for example, a
bare
#or symbols-only tag) are simply dropped.
What you typed still appears in your caption exactly as you wrote it — normalization affects how the tag is indexed, not how your text looks.
Reserved tags
A small set of tags is reserved and won't be indexed on
ordinary posts: #ad, #sponsored, #verified,
#seldeo, and #official. These words carry meaning
about disclosure and authenticity that a caption shouldn't
be able to claim for itself. You can still write the words
in your text; they just don't function as tags.
Where hashtags show up today
Right now, hashtags are stored with your post and shown in the caption. Tag-based browsing — tapping a tag to see other posts using it — is not available yet; it's part of the discovery work we're building next. We'd rather say that plainly than pretend the surface exists.
What tags do not change today: adding a hashtag does not
widen your post's audience. A friends-only post with
#baking is still visible to your friends only.
Using them well
- Tag what the post is actually about; two or three accurate tags beat twenty speculative ones.
- Prefer established spellings (
#bookclub, not#b00kclub) — normalization can't merge creative variants. - Underscores are the only separator:
#sunday_baking.
