How to Choose Hashtags That Actually Get Reach

Hashtags help the right people find your post — but only if you pick them well. Stuffing in the biggest tags actually hurts: your post drowns under millions of others in minutes. Here's how to build a set that gets reach, plus a free tool to generate ideas.

Mix hashtags by size

The trick is a spread, not all giants. Think of three buckets and pull a few from each:

• Large (500k+ posts) — broad reach, but you rank for seconds. Use a few.
• Medium (50k–500k) — the sweet spot; enough audience, less competition. Use most of your set here.
• Small / niche (under 50k) — highly relevant, easier to rank and stay visible. Include several.

Describe your post in the Hashtag Generator to get a batch of relevant tags fast, then sort them into these buckets.

Relevance beats popularity

A hashtag is a search. If your tag doesn't match your content, the people who find you won't care — and the algorithm learns your post is a poor match. Always choose tags that genuinely describe the post, the audience, or the niche.

How many should you use?

• Instagram: 5–15 well-chosen tags outperform the old “max them out” advice.
• TikTok: 3–5 relevant tags plus one or two broad ones.
• X / Threads: 1–2 — more looks spammy.
• LinkedIn: 3–5 professional, topic-specific tags.

Build a few reusable sets

Save two or three ready-made groups for your recurring content themes so you're not starting from scratch every post. Refresh them every month or two — hashtag sizes shift, and reusing the exact same block forever can look automated.

Pair them with a strong caption

Hashtags get you discovered; the caption gets the save and the follow. Draft one with the Caption Generator, tidy your bio, and browse the rest of the AI tools.

FAQ

Do more hashtags mean more reach?

No. Beyond a point they look spammy and dilute relevance. A tight, well-sized set beats a wall of tags.

Should I put hashtags in the caption or first comment?

Either works on Instagram now. Pick one and stay consistent; keep the caption itself readable.

Is the hashtag generator free?
