How to Check for Fake Followers: Metrics, Tools & Tips to Spot Inauthentic Audiences

Influencer marketing continues to be a powerful strategy for brands aiming to connect with their target audiences. However, the rise of fake followers and fraudulent engagement poses significant challenges. 

It is estimated that 45% of Instagram influencers take part in obtaining fake followers. This alarming statistic underscores the importance of verifying the authenticity of an influencer's audience before collaboration.

In this article, we'll delve into why they are a problem on social media platforms, exploring both manual and tool-based methods on how to check for fake followers. By understanding and utilizing these metrics and tools, brands can ensure their marketing efforts reach genuine audiences, maximizing return on investment and maintaining brand integrity.

What are fake followers and how can they affect brands?

Fake followers are inactive or fake social media accounts, including bots, that are usually created to mass-follow other social media profiles for money. Unfortunately, this is a growing business in social media marketing. Both brands and influencers may buy followers to increase their reputation, believing that a larger audience will enhance their market perception.

However, this works exactly the opposite way. Building an audience with fake followers can be detected through various methods we'll discuss later on. Once exposed, it can ruin the brand or influencer’s image. Additionally, it lowers engagement since these followers won’t interact with their content.

Therefore, fake followers represent a risk for brands on both ways:

  1. Having fake followers on your own social media platforms.
  2. Aligning with influencers who have a large number of fake followers within their audiences.

Let’s explore the main reasons for both cases!

1. How can fake followers hurt your brand’s social media account?

  • They will lower your engagement rate as they won't be interacting with your content, keeping you overall metrics at a lower level.
  • They harm potential partnerships. Influencers could take a look at your account before accepting a brand collaboration and may notice suspicious followers or sudden brand follower growth.
  • They make your account overall less credible. For example, suspicious comments on your posts may look like you’ve purchased fake engagement.

It's inevitable to get some fake accounts following you since they are likely paid to follow accounts randomly. However, this can affect your reputation, as you want to avoid other accounts noticing that a large part of your audience consists of these fake accounts. That’s why it’s important to conduct manual and frequent checks and clean up fake followers on your Instagram page or other social media platforms, to ensure you have an organic and engaged audience.

2. How can fake followers affect your influencer marketing campaigns?

Engaging with influencers who have fake followers will make you waste your budget since they will be promoting your product to fake accounts such as bots and inactive accounts.

That’s why it’s essential to audit the amount of fake followers an influencer has before partnering up with them. 

Let's discuss the different ways you can identify fake followers for both your own brand’s account and the influencers you’re planning to engage with!

What Is A Fake Follower Check

A fake follower check is a method used to analyze the authenticity of a social media account’s audience. It helps identify followers that are inactive, bots, or created solely to inflate follower counts. These fake accounts usually don’t engage meaningfully with content and can distort an influencer's true reach and performance.

Running a fake follower check is essential when evaluating potential influencers to partner with, as it ensures your brand’s message reaches real people who are likely to interact and convert. These checks can be done manually by reviewing suspicious patterns or with specialized tools that offer detailed reports on audience credibility, engagement quality, and more.

How to check an influencer’s Fake Followers

1. Calculate the Engagement Rate

The engagement rate (ER) calculates the overall interaction the audience has with the influencer’s content. It measures the amount of shares, clicks, saves, likes and comments on a social media post. If an influencer has a large amount of fake or mass followers within their audience, the engagement rate will be unusually low, as these accounts are mostly inactive. Therefore, calculating their engagement rate can provide some insights about their audience composition and behavior.

To calculate the engagement rate percentage, you can follow the formula below, or you can just use our free engagement rate calculator.

Engagement Rate=(Total Engagements​/Total Followers or Impressions )×100

What Engagement Rate (ER) May Indicate Fake Followers?

What average ER would be suspicious for having a large amount of fake followers? It’s hard to establish a benchmark since it depends on each niche or category and the size of the creators. However, our records show that a solid average ER varies from 1% to 2%, depending on the influencer's following size. Typically, we expect a bit higher ERs from smaller accounts. Therefore, an ER between 0% and 0.5% could be suspicious, and it’s best to try to avoid such accounts.

2. Scan some of the influencer’s followers profiles

You can manually try to spot fake followers within the influencer’s audience by clicking on some of their followers profiles. Some potential signs which indicate fake accounts include:

a. Generic or limited profiles

  • Few or no posts.
  • If they have any posts, these could be mainly stock images with no real people
  • Random or spammy usernames
  • No description or bio
  • Missing profile image
  • Skewed Following To Followers Ratio: following a large number of accounts but they have a very small number of followers

b. Suspicious engagement on their posts

Scan through some of their posts and take a look at the comments on them. In the current business of fake followers, it's quite common to buy them to comment on posts to increase engagement. These can be identified by repetitive and generic comments that don’t completely relate to the influencer’s content or are not personal. 

If you see a majority of these types of comments, such as “Great post” or only emojis, you can click on a few of them to double-check if these profiles show signs of being fake accounts by following the steps described above.

Spam comments from fake followers can be easily detected within a post

3. Unusual follower growth rate

When an influencer buys fake followers, we can typically see a sudden spike in their follower growth rate, followed by a quick drop, instead of a more consistent growth over time.

An influencer might have rapid organic growth if any of their content goes viral, but this is usually followed by a more stable period instead of a marked up-and-down pattern. Therefore, it may be good to look at this rate over the last 3 to 6 months to notice any suspicious increases in their follower base.

Key Metrics to Spot Fake Followers

To identify fake followers, brands and marketers typically analyze a few essential metrics:

  • Follower-to-Engagement Ratio: A high number of followers with very low likes, comments, or views often signals inauthentic audiences.

  • Engagement Quality: Spammy or irrelevant comments (like emojis or generic phrases) can be a red flag.
  • Follower Growth Patterns: Sudden spikes in follower count often suggest purchased followers or bot activity.
  • Audience Demographics: Mismatches between an influencer’s content and the audience’s country, language, or age group can indicate fake or irrelevant followers.
  • Account Activity: Inactive or low-posting follower accounts that follow thousands of users are often fake.

Platform-Specific Tips: Instagram, TikTok, and YouTube

Different social media platforms require unique approaches when detecting fake followers:

  • Instagram: Focus on engagement rates, story views vs. post likes, and comment authenticity. Watch out for large numbers of followers but minimal story engagement.
    TikTok: Analyze video views compared to follower count. Fake accounts may have millions of followers but only a few hundred views per video.
  • YouTube: Check for view-to-subscriber ratios. A high subscriber count with low average views per video can signal an inflated follower base.

Tools for doing a Fake Followers check

Doing a manual search can be time-consuming, especially for macro influencers, and it is hard to scale if you’re working with a large number of influencers.

Here are some of the most effective tools brands use to audit influencer audiences:

  • HypeAuditor: Offers fake follower audits, engagement analytics, and audience demographics across Instagram, YouTube, and TikTok.
  • Modash: Provides real-time data on fake followers, engagement rates, and audience quality. Also integrates with influencer discovery tools.
  • Influencer Hero: Includes fake follower detection as part of its all-in-one influencer marketing platform. Brands can view audience credibility scores, detect suspicious growth patterns, and filter influencers based on real engagement quality across Instagram, TikTok, YouTube, and more.

How Influencer Hero Stands Out Among Tools for Detecting Fake Followers

There are multiple tools available to help brands detect fake followers and assess audience credibility—each offering different features and levels of insight. However, Influencer Hero takes the lead as one of the most comprehensive and user-friendly solutions in the market.

Influencer Hero is an all-in-one influencer marketing platform designed to streamline every stage of your campaign. From identifying influencers using advanced filters to managing outreach and tracking performance, the platform makes your workflow more efficient. 

Types of Followers Our Software Detects

Our software identifies four types of followers within an influencer’s audience:

  • Real people: Human followers with real and active accounts. This is your target audience with whom you want to connect.
  • Influencers: Other creators who also generate content for a living. Influencers often support each other by commenting on each other’s posts to help increase engagement. Therefore, an account with a majority of influencers following isn't ideal, as they are not your target audience or potential customers.
  • Mass followers: Accounts that follow a lot of influencers indiscriminately, typically more than 1,500 accounts. This can be a sign that they don’t actively interact with all their following accounts, since Instagram’s algorithm won’t show content from most of the accounts they are following.
  • Suspicious accounts:  These show overall behavior or characteristics that raise doubts about their legitimacy. These are potential fake followers or bots.

Both mass followers and suspicious accounts are perceived by brands as red flags for account authenticity and credibility.

Credibility percentage

According to the followers types’ segmentation, Influencer Hero’s analytics also offers a percentage of audience credibility. Though it is hard to establish a parameter of credibility you should consider for working with an influencer, the median audience credibility for influencers is around 60 to 75%, depending on their followers size. Our influencer marketing software will provide insight not only on the percentage but the range in which this is normal for the market. 

However, it is suggested that you make a decision based not only on fake followers % but on the overall picture. Take a look at other metrics such as engagement rate and audience demographics to see if it is worthy to invest in them.

Audience credibility is a key factor in determining an influencer’s potential to reach your target audience

Data and Insights Our Free Fake Follower Check Tool Provides

1. Audience Location

It's probably useless to partner with an influencer who has +1M followers and can get you wide reach while 70% of their audience is located in Japan, if you have a store located in the United States which only ships products there. It’s essential to ensure you are targeting the right audience, by analyzing every detail of the influencer’s audience.

2. Audience Demographics

This includes audience gender split and age demographics. These factors ensure that you reach precisely the people within your target audience. For example, if you are a maternity brand selling baby products, it would be essential to collaborate with an influencer whose primary audience consists of females aged 25-45.

3. Fake Followers Percentage

Our tool provides a percentage of fake followers and its average across market, regarding influencers from the same size. As discussed, it’s essential to make sure that you’re partnering with influencers who have an authentic and engaging audience.

4. Estimated Sales & EMV (Earned media Value)

All marketers are eager to estimate how much an influencer could sell, as ultimately all marketing strategies come down to sales. Our tool will assist you in predicting estimated sales and EMV, according to their previous performance and overall KPI’s.

5. Follower growth rate

As we saw previously, follower growth during the last few months is one indicator of audience credibility. Additionally, it is one of the main metrics that correlates with conversion, as an active and increasing audience will impact the campaign’s performance.

How Brands Use Fake Follower Audits in Influencer Campaigns

Brands rely on fake follower audits to ensure their marketing dollars are well spent. Here’s how:

  • Campaign Vetting: Before finalizing partnerships, brands audit influencer accounts to ensure audience authenticity and real engagement.
  • ROI Optimization: Removing influencers with fake audiences helps improve ROI by focusing on real reach and conversions.
  • Compliance & Transparency: Many brands are now legally required or ethically committed to working only with authentic influencers, especially in regulated industries.
  • Performance Benchmarking: By comparing audit scores, brands can prioritize influencers with better audience quality over those with inflated numbers.

Final Thoughts On Fake Follower Check

Avoiding fake followers is essential for maintaining credibility—both for your brand’s own accounts and the influencers you collaborate with. Regularly checking for fake followers helps ensure your content reaches real people and that your marketing budget is well spent.

You can manually review profiles or use key metrics like engagement rate to spot suspicious activity. However, for deeper insights, influencer marketing tools offer detailed audience analysis.
