How Many Hashtags Should You Really Be Using in 2025?

Let’s be real—hashtags used to feel like the golden ticket. The more you threw into your caption, the better your chances of being seen, right? Not anymore. In 2025, the rules have changed, and the platforms are making it clear: it’s not about how many you use, it’s about which ones you choose—and what else you’re doing to get noticed.

TikTok: 5 and Done

TikTok limits you to five hashtags per post. That means you’ve got to be intentional.

👉 My tip: pick a mix of broad hashtags (like #SmallBusiness or #ContentTips) and hyper-specific ones that connect directly to your audience.

Instead of overloading hashtags, also try:

• Writing keyword-rich captions (TikTok’s search feature loves this).

• Using trending sounds or effects to boost discoverability.

• Adding text overlays with keywords that match what people are searching for.

  
  

Instagram: 3–5 Is Your Sweet Spot

Instagram recommends 3–5 hashtags per post—because hashtags here are about categorization, not reach.

👉 Think of hashtags like labels on your content drawer.

Other ways to get seen on IG:

• Put strong keywords in your captions (Instagram search is keyword-heavy now).

• Use carousels and Reels—IG pushes them harder than still posts.

• Write captions that spark engagement (comments boost you way more than hashtags).

  
  

LinkedIn, Facebook & YouTube: Keep It Simple

On these platforms, hashtags are secondary. Two or three good ones are enough.

Better plays than hashtags here:

• On LinkedIn: post thought leadership content, use keywords, and encourage conversation in comments.

• On Facebook: lean into Groups and shareable content.

• On YouTube: optimize titles, descriptions, and tags—hashtags are optional.

  
  

X (Formerly Twitter): Stick to 1–2

Even before hashtags were banned from paid ads this year, X users were moving toward just one or two hashtags per post.

What works better than hashtag stuffing:

• Write tweets with strong hooks that invite replies.

• Use keywords so posts show up in X’s new search-driven feeds.

• Tap into trending conversations without forcing random hashtags.

  
  

The Big Takeaway

Hashtags aren’t gone—they’re just not the star anymore. They’re one small part of a bigger strategy. Focus on:

• Fewer, smarter hashtags.

• Keyword-rich captions and titles.

• Content formats your platform prioritizes (Reels, Shorts, Threads, carousels).

• Real engagement—comments, shares, saves, and conversations.

  
  

Here’s your quick cheat sheet for 2025:

• TikTok: 5 hashtags only

• Instagram: 3–5 hashtags

• LinkedIn/Facebook: 2–3 hashtags

• X (Twitter): 1–2 hashtags

✨ My advice? Hashtags can still help, but they’re not your whole strategy. If you really want to be seen, start focusing on SEO-style keywords, trending formats, and authentic engagement. That’s what will keep your content growing in 2025.
