How to Use Right Hashtags on Instagram

The word that trips up most people isn't "hashtags," it's "right." Plenty of Instagram accounts use hashtags diligently and still see nothing, because they're using popular hashtags rather than the right ones for their content and their account. Getting this correct is less about volume and more about fit: choosing tags that genuinely describe your post, match your account's size, and reflect what your ideal viewer would actually search. This guide is about how to identify the right hashtags, not just any hashtags, and how to tell the difference.

What "right" actually means

A right hashtag satisfies three tests at once. It's relevant, meaning it truly describes the content of your post. It's reachable, meaning your account is big enough to compete in that tag's feed. And it's intentional, meaning the people browsing it are the people you want to reach. A tag can be wildly popular and fail all three. #photooftheday is relevant to almost any photo, hopelessly unreachable for a small account, and browsed by no one with specific intent. That makes it a wrong hashtag despite its popularity.

Once you internalise those three tests, choosing hashtags stops being a popularity contest. You're not asking "which tags are big," you're asking "which tags describe this post, that I can rank in, and that my ideal viewer is browsing." The shift sounds subtle, but it changes every decision that follows. It means you'll sometimes pass over a hugely popular tag in favour of a smaller one, and that choice, counterintuitive as it feels, is exactly what separates accounts that grow steadily from those that post constantly yet stay invisible.

Relevance is the non-negotiable filter

Relevance matters more than any other factor because Instagram watches how people respond to your post after they find it. When a hashtag brings viewers who quickly scroll past, that weak response tells the algorithm your content isn't satisfying, and it shows the post to fewer people. When a hashtag brings viewers who like, save, and linger, the opposite happens. So an irrelevant but popular tag doesn't just fail to help; it can actively drag your reach down by importing the wrong audience.

The practical rule: never add a tag just because it's trending or huge. Ask whether someone browsing that exact tag would be glad to find your specific post. If the honest answer is no, it's the wrong tag no matter how many posts it has.

Match hashtag size to your account

The second test, reachability, is where most well-meaning accounts go wrong. Instagram hashtag feeds have a "top" section that delivers lasting reach, and to appear there you need enough early engagement to compete with everyone else using the tag. On a tag with millions of posts, a small account simply can't, so the post vanishes in seconds.

Choose tags sized to your reach. A rough guide:

• Under 5,000 followers: focus on tags with roughly 5,000 to 100,000 posts.
• 5,000 to 50,000 followers: add tags up to a few hundred thousand posts.
• Larger accounts: can compete in bigger tags, but should still keep most of the set mid-sized.

Ranking in a smaller, relevant tag beats being invisible in a giant one every single time, and as your following grows you can gradually graduate into larger tags you couldn't touch before.

Finding the right hashtags is a short research process, not a guess:

• Describe your post honestly in plain words: subject, style, audience, occasion. These become your candidate tags.
• Search each candidate in Instagram and read the related suggestions plus each tag's post count.
• Open the tag's feed and inspect the top posts. If they resemble your content, the tag fits; if they look completely different, it's wrong for you.
• Study peer accounts your size in your niche and note which mid-sized tags recur on their best-performing posts.
• Group your winners into a small library so you're choosing from vetted tags each time.

This is how you find tags that pass all three tests, rather than copying a generic list that passes none.

Avoid the wrong tags: banned and broken ones

Some hashtags are actively harmful to use. Instagram restricts certain tags, sometimes ordinary-seeming words that have been abused, and posting to a banned or flagged tag can suppress your entire post's reach. You can spot trouble when a tag's page shows a warning message or displays almost no recent posts despite a high count. If you see either sign, remove the tag immediately.

It's worth periodically re-checking the tags in your saved sets, because a tag that was fine can later become restricted. A single flagged tag riding along in an otherwise good set can quietly cap everything you post, so this quick hygiene check protects all your other right choices.

Confirm you got it right with your data

The final step is verification. Instagram insights show, on each post, how much reach came from hashtags versus your followers and profile. That number tells you whether your tags are actually working. If hashtag reach is consistently low, your tags are probably too big, too generic, or not quite relevant, and it's time to adjust toward smaller, sharper choices.

Track which tags reappear on your best-reaching posts and treat those as proven. Retire the ones that never contribute, and as your account grows, gradually promote yourself into slightly larger tags you can now compete in. This turns hashtag selection into a living, improving system tuned to your specific account rather than a static list.

If the research and sizing feels tedious, a tool like EasyHashtags can help surface related, appropriately-sized tags so you spend less time counting posts and more time judging relevance. But the judgment is the real skill: the right hashtags are the ones that honestly describe your post, that your account can realistically rank in, and that your ideal viewer is genuinely browsing. Apply those three tests to every tag, prune with your insights, and you'll stop using popular hashtags and start using the right ones.
