Are they alive? Are they dead? Does #sweaterweather even mean anything anymore?!
From megaphones to filing cabinets
The truth is, hashtags are still here. They just aren’t what they used to be. Hashtags have gone from a quick way to expand reach and get instant distribution to mostly being used to categorize content. Think of them as labels rather than megaphones.
These days, a hashtag is one clue among many. Platforms also read your caption, the text on your video, and even what you say out loud. Whether anyone actually sees your post comes down to whether people watch, save, and share it. The hashtag just tells the app where to file it.
Why everyone thinks they’re dead
Over the last couple of years, platforms have slowly pushed hashtags out of the spotlight. In 2024, LinkedIn and Instagram both removed the option to follow hashtags, and plenty of creators took that as a sign that hashtags were officially useless. X went even further and banned hashtags from ads entirely in 2025.
But nobody following your hashtag isn’t the same as your hashtag doing nothing. Say you post a creamy tomato soup recipe in October. Your caption, the text on your video, and a #soupseason tag all tell the platform the same thing: this is a fall recipe. So when someone searches “easy soup recipes,” your post has a real shot at showing up. And since July 2025, public posts from Instagram business and creator accounts can show up in Google results too. The hashtag didn’t get you there alone, but it backed up everything else in your post.
That matters more than ever, because people are searching on social media constantly. In one TikTok-commissioned study, 86% of Gen Z said they search on TikTok every week.
The five-tag era
Instagram and TikTok have both cracked down on hashtag overuse. Instagram cut its limit from 30 to 5 per post in December 2025. TikTok, which never had a cap before, quietly started limiting posts to 5 in August 2025. Instagram’s stated goal was spam control: cutting down on generic tags like #reels and #explore and pushing creators toward more specific, relevant tags. The change wasn’t random, either. Instagram spent about a year testing limits, with some users capped at just three tags per post.
What the data actually says
Here’s where it gets interesting. Metricool’s 2026 study of more than 24 million Instagram posts found that posts with hashtags got about 31% fewer views than the platform average. Their LinkedIn study found the opposite: posts with hashtags got 85% more impressions.
Before you go delete every hashtag you’ve ever written, here’s the catch. These studies show a pattern, not a cause. The Instagram accounts leaning hard on hashtags might just have weaker content overall, and the LinkedIn accounts using them might just be posting more strategically. So no, the numbers don’t mean hashtags are useless. They mean hashtags aren’t what decides how a post performs. Your content is.
Where hashtags still win
Some hashtags still pull their weight, especially niche community tags. Since 2020, #BookTok has racked up more than 100 billion views, and bookstores now set up “BookTok tables” for titles that went viral. A hashtag started it, and now there’s a whole new table at your local bookstore.
What about #fyp?
Adding #fyp or #foryou won’t get you onto TikTok’s For You page. TikTok decides what to recommend based on how people interact with your video and on details like your caption, sound, and descriptive hashtags. #fyp just tells TikTok you want views. Same, honestly. But it isn’t a category, so it doesn’t help.
For the marketers
Here’s what you need to know:
- X: 1 to 2 hashtags at most. The X Help Center recommends no more than two per post.
- Facebook: 0 to 3. Any more than that tends to look spammy.
- Instagram and TikTok: 3 to 5 specific hashtags. Both platforms cap you at 5 anyway.
- Everywhere: Put the words people would actually search for in your caption. That’s where discovery happens now.
The cold, hard truth
Hashtags aren’t dead, but they’ve been demoted from a growth hack to a filing system. These days, getting found comes down to clear captions, real keywords, and content people actually want to share. Use hashtags to help the app sort your post, and let the post itself earn its keep.
