Heard: hashtags vs plain keywords for discovery — the winner switched
Confirmed: X indexes full-text search; a post is findable by its words whether or not they're hashtagged.
Rumored: as of this period, hashtag-stuffed posts get a mild reach discount — the system reads 3+ tags as a low-quality signal — while natural keyword usage carries none.
Use which when:
— Keywords in plain prose: always; it's how search and the topic-graph find you
— One hashtag: only for a live event or branded campaign tag
What it means for your reach: drop the hashtag block. Write the keyword into the sentence instead — 'I tested every email autoresponder' beats the same post with five tags stapled on.
