How Many Hashtags Should You Use?

Advice like "always use 30 hashtags" or "hashtags are dead, use zero" both come from generalizing one platform's norms to every platform. The actual answer changes depending on where you're posting, and treating it as one universal rule is the most common mistake creators make with hashtags.

Instagram allows up to 30 hashtags per post, but that ceiling isn't a target — a smaller, more relevant set at moderate reach (not exclusively huge, oversaturated tags) tends to outperform a maxed-out list padded with tags too competitive to realistically surface in. Quality and relevance to the actual post beat raw count.

TikTok's discovery leans more heavily on video content and caption keywords than on hashtag volume. A handful of sharp, relevant tags (3-5) does the job; piling on more doesn't meaningfully add reach the way it can on Instagram, because TikTok's system isn't primarily indexing by hashtag the same way.

On X, using more than 1-2 hashtags per post is associated with lower engagement, not higher — the platform's culture and algorithm both treat heavy hashtag use as a spam signal. This is the platform where "less" isn't just fine, it's the actual best practice, not a compromise.

Within whatever count you land on, split between high-competition tags (huge reach, low odds of surfacing), medium tags, and low-competition or niche tags (much better odds of being found, smaller audience). A post using only the biggest tags in a niche is competing against everyone; a post that mixes in smaller, targeted tags has realistic paths to actually being seen by them.

Chasing broad reach favors more high/medium-competition tags; building authority in a specific niche favors leaning toward low-competition, niche-specific tags instead. The AI Hashtag Generator on this site groups suggestions by competition level and lets you pick a strategy — Balanced, Broad Reach, or Niche Authority — sized to whichever platform you're posting to, rather than handing you one generic list.
