Do Hashtags Still Matter? What They Actually Do Now

For years the advice was to stuff 30 hashtags under every post and watch reach roll in. That advice is now wrong, and the platforms have said so out loud. But "hashtags are dead" is wrong too. They've just changed jobs, and your strategy has to change with them.

Do hashtags still matter in 2026?

Yes, but not the way the 2019 playbook promised. The clearest signal came from Instagram itself. In February 2025, head of Instagram Adam Mosseri said plainly that hashtags "don't work" to increase reach, and in May 2025 he added that they don't improve visibility but are a good way to let people know what a post is about. Then in December 2025, Instagram capped posts and Reels at 5 hashtags, with the company saying that "using fewer (up to 5) more targeted hashtags, rather than many generic ones, can improve both your content's performance and people's experience on Instagram."

Read those two moves together and the picture is simple. The platform that once made hashtags the engine of discovery now treats a pile of them as noise. The algorithm decides who sees your post mostly from the content itself: how long people watch, whether they save it, whether they send it to a friend. Hashtags are no longer the lever that moves reach.

So what do hashtags actually do now?

They do two real jobs, and both are useful once you stop expecting magic from them.

• They tell the algorithm what your post is about. A hashtag is a label. When you tag a photo of your sourdough #sourdough, you're confirming the topic so the platform can show it to people who like that topic. It's classification, not a megaphone.
• They make your post findable in search. People search hashtags and keywords directly. When someone taps #portlandbakery or types "gluten free cookies" into the search bar, your tagged, keyworded post can show up, sometimes months later. This is the part that still quietly works.

That second job is the one worth leaning into. Search-driven discovery doesn't expire the way a feed post does. A well-tagged post can keep pulling in the right people long after it stops appearing in anyone's feed. So stop thinking of hashtags as advertising and start thinking of them as filing.

How many hashtags should I use?

Fewer than you think, and the platforms now agree on a tight range. On Instagram, the cap is 5, so use 3 to 5, and only ones that genuinely describe the post. On TikTok, ByteDance's own editor CapCut points to 3 to 5 hashtags as the range that performs best, because too many send the algorithm mixed signals about what your video is. The era of 30 tags in a comment is over on the platforms that mattered most for it.

A simple structure works across platforms: pick one broad tag for the category, one or two niche tags for your specific community, and one local or branded tag. For a bakery that might be #bakery (broad), #sourdoughbread and #artisanbread (niche), and #portlandbakery (local). Five labels, each one accurate. If you can't honestly say a tag describes the post, drop it.

What should I tag instead of generic hashtags?

Specific beats popular, every time. A tag like #love or #instagood has tens of millions of posts and zero intent behind it; nobody searching #love is looking for your cookies. A tag like #glutenfreebaking is smaller, but the people using it want exactly what it describes. That specificity is what makes the search job pay off.

A rough check: lean toward tags that are big enough that people actually search them but small enough that your post isn't buried under a million others within seconds. That keeps you out of both traps, the tags so huge you vanish and the tags so tiny no one looks. Use the search bar to feel out where a tag sits before you commit to it.

Are keywords now more important than hashtags?

For getting found, yes, and this is the real shift behind the hashtag story. Instagram and TikTok both function as search engines now, and they read the actual words in your post, not just the tags. This is what people mean by "social SEO."

So the words you say and show matter as much as the # symbols:

1. Write a real caption. Put the plain-language phrase your customer would search, like "easy weeknight dinner" or "first-time home buyer tips," in the first sentence, not buried at the bottom.
2. Say it out loud in video. TikTok and Reels transcribe your audio. If you say your keyword in the first few seconds, the platform indexes it.
3. Put it on screen. Both apps read text in your video frames. A title card with your topic isn't just for viewers, it's for search.

On TikTok especially, treat your hashtags as keywords. Tag #bestbudgetlaptop instead of #tech, because the first is something a buyer actually types into search and the second is something nobody does.

What's the simplest hashtag routine I can actually keep?

You don't need a spreadsheet of 200 rotating tags. Build a small, reusable kit and stop overthinking it:

• Keep a list of 10 to 15 strong tags that genuinely fit your business: a few broad, several niche, one or two local. You'll reuse these.
• Per post, pick the 3 to 5 from that list that match what's actually in the post. Swap one in occasionally if the post is unusual.
• Write the caption with a searchable phrase up front, then add the hashtags. The caption does more work than the tags do.
• Don't use tags that are obviously irrelevant or spammy. Otherwise, relevant tags are fine; there's no secret blocklist to fear.

That's the whole system. Spend the time you used to spend on hashtag research on a clearer first sentence and a better hook instead. That's where reach actually comes from now.

If the bottleneck is finding the time to write captions and tags for every platform each week, that's the gap Laspi is built for: you record one weekly voice note about what's new and add a few photos, and it returns a week of posts shaped for each platform, captions, suggested keywords, and a tight set of relevant hashtags that you review and publish yourself. It won't make hashtags magic again, because nothing will. It just keeps the labeling consistent so you can stop fussing over it.

The short version

Hashtags didn't die. They got demoted from growth driver to filing system. They no longer buy you reach; the content does that. What they still do is help platforms understand your post and help searchers find it later. So use a handful of specific, accurate tags, write a caption with a real search phrase in it, and put your effort into the post itself. That's the strategy that survives the next algorithm update, because it's not a trick. It's just being clear about what you do.
