Turn a topic into a tidy set of relevant hashtags, sized right for each platform instead of a spammy wall of fifty. Type, generate, copy.
Separate ideas with commas. The more specific, the better the set.
8 to 15 focused tags beat the old 30-tag dump.
Use a small set of specific, on-topic hashtags that describe the post, not a generic wall meant to chase reach. In 2026, platforms read the caption, audio, and on-screen text to understand content, so accurate tags act as a topic label rather than a growth hack.
As a general 2026 starting point, use 3 to 5 relevant hashtags on Instagram, TikTok, LinkedIn, and YouTube, and 1 to 2 on X and Facebook. These are general guidelines to test against your own analytics, not a study or a hard rule.
| Platform | Recommended hashtags | Note |
|---|---|---|
| 3 to 5 (up to ~10) | A few tight, on-topic tags beat the old 30-tag wall in 2026. | |
| TikTok | 3 to 5 | Mix one or two broad with specific niche tags; let the caption carry context. |
| X (Twitter) | 1 to 2 | More than two reads as spam and can suppress reach. |
| 3 to 5 | Professional, topic-level tags; skip jokey or oversized sets. | |
| YouTube | 3 to 5 (in description) | The first few matter most; the title and topic do the heavy lifting. |
| 1 to 2 | Low hashtag value; keep it minimal and topical. | |
| 2 to 5 | Treat tags as keywords that describe the pin. |
General guidance for creators and small teams, not a hard rule. Treat as a starting point and adjust to your own reach. See the per-platform tools under platforms we support.
How many hashtags should you use per post?
It depends on the platform. As a general 2026 guideline, use 3 to 5 relevant hashtags on Instagram, TikTok, LinkedIn, and YouTube, and just 1 to 2 on X and Facebook. A few tight, on-topic tags consistently beat a wall of fifty.
Is the PostDodo hashtag generator free?
Yes. It is completely free and needs no signup or account. Type a topic, generate a set, and copy it. The paid scheduling tool is separate and only needed if you want to schedule and auto-publish posts.
Do hashtags still work in 2026?
They still help discovery, but their role has shifted. Platforms lean on the caption, audio, and on-screen text, so a small set of accurate, specific hashtags beats a large generic one. Use them to label the topic, not to game reach.
Should I use the same hashtags on every platform?
No. Sizing differs by network. Start from one relevant set, then trim or swap per platform. Try our other free tools like the character counter and the best time to post tool to round out a post.
