The best Instagram hashtags to grow your reach on social media

An introduction to hashtags on Instagram

Hashtags are words or phrases preceded by the # sign, used to categorize content on social media. On Instagram they work as labels that help people find posts tied to a particular topic or interest. That's how your content can be discovered by people who don't follow you yet but are searching for posts in your industry.

Instagram lets you add up to 30 hashtags to a single post, but the platform itself recommends 3 to 5 hashtags under one photo. The key is that hashtags stay tightly tied to what you actually published – don't use them just to farm more likes or followers, because Instagram can penalize you for spamming.

How hashtags work in a social media strategy

Hashtags on Instagram are actively scanned by Instagram's algorithm. Every time someone taps a hashtag or types it into search, they see every public post that carries it. That turns well-chosen Instagram hashtags into a bridge between your content and the people who might want it.

A well-planned hashtag strategy supports engaging posts and interactions, because it helps you reach the audience that genuinely cares about the topic you're covering. Based on years of experience at the Social Lama agency and our specialists in full-service brand communication on social media, the brands that do best are the ones that combine popular hashtags with niche, industry-specific tags.

Choosing the right hashtags for maximum reach

Choosing the right hashtags is critical if you want more reach, and it shouldn't happen by accident. Without a well-chosen hashtag, even the best content won't reach its audience. That's exactly why many companies decide to hand their profile and social media management to a professional agency. The best strategy is to mix hashtags of different popularity levels – from the most popular (millions of posts) through the mid-range (hundreds of thousands of posts) all the way to niche, industry hashtags (tens of thousands of posts).

A good move is to use tools like TagsFinder, which help you find the right hashtags from the keywords that describe your post. You can also use Instagram's own search to check which hashtags are popular in your industry right now and how often they're used.

Remember that hashtags should match the interests and needs of your target audience. If you run a fitness profile, hashtags like #fitness, #healthylifestyle or #homeworkout will do the job. For fashion bloggers, #fashion, #ootd (outfit of the day) and #style work well.

The most popular Instagram hashtags in 2025

According to the latest analyses, the list of the most popular hashtags on Instagram is made up of universal tags used by millions of people around the world. Here are the most popular hashtags worth considering in your strategy:

The most popular hashtags globally:

• #love – the most popular hashtag on Instagram, with over a billion posts
• #instagood – marks photos considered especially good
• #photooftheday – popular with photographers
• #fashion – a must-have for the fashion industry
• #beautiful – used to describe anything beautiful
• #travel – perfect for travel bloggers
• #fitness – popular in the healthy-living world

The most popular Polish hashtags (if Poland is your market):

• #polishgirl
• #poland
• #polska
• #warszawa
• #polishboy
• #polskadziewczyna

These top hashtags can help you reach a wide audience, but remember that the competition under them is enormous, so your content has to stand out on quality and originality.

Banned hashtags – what to avoid at all costs

One of the biggest threats to your reach on Instagram is banned hashtags. Instagram blocks hashtags that break the Community Guidelines, so the platform hides posts that carry them in captions or comments. The list of banned hashtags is dynamic and can run to more than 1,800 different tags.

Examples of banned hashtags include the obvious cases like #sex and #ass, but also seemingly innocent words like #mirror, #babyelephant, #boho, #always and #appleiphone. Using banned hashtags can land you a shadowban – a penalty that drastically cuts the reach of your posts.

To check whether a hashtag is banned, type it into Instagram's search. If the hashtag is blocked, you'll see a message saying the related content has been hidden. You can also use tools like MetaHashtags to verify the status of hashtags before you publish.

Best practices for using hashtags

Using hashtags effectively takes a strategic approach. Here are the most important rules to help you get the most out of them:

Rules of quantity and quality:

• Use at most 30 hashtags per post, but the optimal number is 3-5
• Mix popular hashtags with niche ones
• Match hashtags to the specific content of the post
• Avoid using the same hashtags on every post

Where to put hashtags:
You can put hashtags directly in the post caption or in the first comment. Both are equally effective, but putting them in a comment keeps the caption looking cleaner.

Tracking performance:
Monitoring how the hashtags you use perform lets you optimize the strategy. Pay attention to which hashtags bring the most reach and engagement, and which are better avoided.

The experts at our marketing agency Social Lama stress that what matters most is systematically testing different hashtag combinations and adapting the strategy to shifting trends and the needs of your target audience.

Mistakes to avoid when using hashtags

Even a well-planned hashtag strategy can backfire if you make the basic mistakes. Here are the most common traps that can hurt your reach:

Using only the most popular hashtags: Hashtags like #love or #instagood have millions of posts, but the competition under them is so heavy that your post can quickly disappear in the flood of content.

No connection to the content: Using hashtags unrelated to the post can be treated as spam by Instagram's algorithm and get your reach cut.

Ignoring trends: Social media changes fast, so it's important to follow the latest trends and adjust your hashtag strategy to them.

Overusing hashtags: Repeating the same hashtags too often can be read by Instagram as bot behavior and earn you a shadowban.

Summary

Using hashtags well on Instagram is still one of the most effective ways to grow reach organically in 2025. The key is finding the right hashtags, ones that combine popularity with a genuine fit to your target audience and your content. Remember to avoid banned hashtags, monitor how your strategy performs, and keep adjusting to shifting trends on social media.

An effective hashtag strategy is a process of constant learning and optimization. There's no universal recipe for success – what works for one brand won't necessarily deliver for another. That's why what matters most is systematic testing, analyzing the results, and gradually refining your approach to hashtags on social media.

FAQ: how to use hashtags to win new followers

How many hashtags should I use in one Instagram post?

Instagram allows a maximum of 30 hashtags per post, but experts recommend using between 11 and 15. Quality and fit to the content of the post matter more than quantity. It's better to use a smaller number of well-chosen hashtags than the maximum number of random ones.

How do I check whether a hashtag is banned?

The simplest way to check a hashtag's status is to type it into Instagram's search. If the hashtag is banned, you'll see a message about hidden content, or the hashtag won't show up at all. You can also use tools like MetaHashtags to check the status of a larger batch of hashtags automatically, all at once.

Is it better to put hashtags in the caption or in a comment?

Both are equally effective in terms of reach. Putting hashtags in the caption gives them immediate visibility, while adding them in the first comment keeps the caption looking cleaner and more professional. The choice comes down to your aesthetic preferences and your communication strategy.
