Why Hashtags and Bio Keywords Work in Influencer Discovery?

Anyone that works on influencer marketing can tell you that finding the right creators is not as simple as it seems. You need a creator that beyond follower count, aligns with your brand and more importantly your audience.

This is when bio keywords and hashtags come in handy, being two of the most effective signals available. They tell you what creators are talking about and how they identify themselves.

Hashtags: What They Post About

In content discovery hashtags play an essential role. They act as a window into the type of content an influencer constantly shares, and what they want to be discovered for. Whether it’s #fashion, #plant-basedrecipes, or “#fitness”, creators use hashtags mostly to:

• Join niche communities
• Tag their content for visibility
• Signal relevance to potential brand partners

For brands, that means you can instantly find creators who are already talking about the topics that matter to your audience.

Bio Keywords: How They Describe Themselves

Bios allow influencers to introduce themselves to the world. And specific keywords are useful to reveal who they are. Most creators make straightforward yet specific descriptions in their bios using phrases like:

• “NYC-based fitness coach”
• “Dog mom + lifestyle content”
• “Vegan chef”
• “Ex-Google + Career coach”

With these self-descriptions you’re not only able to find creators that fit your exact niche, but also that have the credentials and experience you need. The challenge is that most social platforms don’t let you search bios easily - or at all.

Manual Search vs Smart Search

So how does using hashtags and bio keywords look like in reality? There are two main ways to use bio keywords and hashtags for influencer discovery: Manually vs smart search through tools like Influencer Hero.

Let’s do a little experiment. Let’s say that you’re a U.S. brand that sells gymwear and you’re looking for Instagram fitness influencers located in NY. Here’s how this will look like using both approaches.

Manual Search

Instagram (and most platforms don’t offer a specific filter to search bios. While the algorithm may surface profiles based on bio content, your main manual discovery tool is still hashtags.

By adding hashtags like “#nycfitness” or “nycworkout” you can find different creators:

For example one of the top results is Syd Miller, fitness trainer and founder of Housework.

But browsing below, you can find influencers like Syd but also other types of creators that aren’t specifically fitness related but have posted workouts in NYC.

Bottom line, this method is effective but it’s extremely time consuming as you need to go one by one ensuring that these are the creators that fit with your brand.

Smart Search: Influencer Hero

By using tools like Influencer Hero, you’re able to search and find the exact type of influencer you’re looking for without needing to browse and scroll through.

Using the “Bio” and “Mentions - Hashtag” filters you can find the exact match:

How to Search Influencers Using Bio Keywords and Hashtags

After you enroll into Influencer Hero and sign in to your account, you can go directly to the Influencer Finder. Here you’re able to search for influencers in the main social media platforms including Instagram, YouTube, TikTok or your own customers.

Influencer Hero has more than 20 filters that allow you to be very specific in terms of the influencers you need. Start by applying the keyword you want in the profile’s bio, ex: Fitness coach, as well as the hashtag, like #fitness.

Then you can go beyond and add more requirements like location, follower range, engagement range, etc.

Based on your needs, you’ll then be able to browse through a list of creators that match your specific request. In this case we suggested a fitness coach from the USA, with a follower range between 10-50K, and an engagement rate above 2%.  

By using these filters you instantly get a list of 167 influencers where you can click on “view analytics” to get a detailed report on their profile, evaluating their engagement rate, audience type, interests, fake follower percentage, previous collaborations and more.

The more specific your search, the more relevant your results. And the best part? You can add influencers directly to your campaigns—no spreadsheets or manual tracking needed.
