CamelCase hashtags (recommended)
Lowercase variant
Ready-made sets per platform
X (Twitter)
Norm: 1-2 hashtags. More than 2 measurably hurts engagement; hashtags matter less on X than they used to.
Norm: 3-5 relevant hashtags at the end of the post. Niche tags outperform giant generic ones.
Allowed: up to 30. Norm: 3-5 high-quality, specific tags now outperform tag walls. This set takes your first 30.
Why CamelCase? Capitalizing each word (#FreeAiCourses instead of #freeaicourses) makes multi-word hashtags readable at a glance and, more importantly, lets screen readers pronounce each word separately instead of reading one long garbled string - it is the accessibility-recommended format, sometimes called PascalCase or "camel case hashtags". Hashtags are not case-sensitive for search, so #AIForMarketers and #aiformarketers reach the same feed; only the display changes. This tool also strips characters hashtags cannot contain (spaces, punctuation, symbols except underscore) and drops duplicates. Avoid starting a hashtag with a number-only word; platforms require at least one letter.
