Top X (Twitter) Hashtags by Category
X is the one platform where a second hashtag measurably costs you reach. One tag, occasionally two, and only when it is a room people are actually standing in — the rest of the post’s discovery comes from the text. These sets are ordered accordingly: the first entry in each is usually the only one worth using.

How many to use: 1–2 on one X post. Every hashtag below is one people actually use in volume, so pick the ones that genuinely describe the post rather than the ones at the top — relevance is what decides whether a large hashtag works for you.
