In the past decade, influencer marketing has exploded in popularity. Everywhere you look, there are influencers promoting products and services for brands. The worldwide influencer market is now worth over $20 billion, more than tripling in value since 2019. Clearly, brands are increasingly investing in this marketing channel, but does it really work? How effective is influencer marketing exactly?

If you’re considering influencer marketing but not sure whether it’s the right choice for your brand, use this guide to make a more informed decision. Let’s break down the ins and outs of influencer marketing, including how it works, the benefits, and some strategies for getting the most out of this marketing channel.
What is influencer marketing, and how does it work?
Influencer marketing is when brands partner with influencers to promote their products or services. Typically, “influencer” refers to social media content creators with dedicated audiences, but influencer marketing can also include notable bloggers, celebrities, and industry leaders.
The key is that influencers have established credibility with their audiences, who care what they have to say. By partnering with influencers, brands can tap into that relationship for effective marketing campaigns.
These campaigns typically start with brands selecting influencer partners. Then, once the brand has at least one influencer partner, they agree on what the influencer will post about the brand and when. Influencer marketing campaigns can be one-off agreements in which the influencer shares a single photo post about the brand or long-term partnerships with several sponsored posts. The brand then tracks the results of the campaign to measure its impact.

Benefits of working with an influencer
Influencer marketing is unique among digital marketing strategies in that brands need to form close working relationships with the influencers who participate in their campaigns. When you choose the right influencers, these campaigns can be incredibly effective. Some of the benefits of influencer marketing include:
Brand awareness and reach
When you work with an influencer, you get your brand in front of their entire audience. The thousands or even millions of people who follow your influencer partners will see the promotional content they post about your brand and hopefully want to learn more. Compared to organic social media marketing, influencer marketing immediately boosts your reach.
Focused and relevant audience
Marketing campaigns geared toward specific audiences are generally much more impactful than broad campaigns that go out to wide, unfocused groups. Just because you’re marketing to many customers doesn’t necessarily mean that many of them will engage with your campaign.
In influencer marketing campaigns, the audience is made up of the influencer partners’ followers. If you select influencers who share content related to your industry or topics of interest to your customers, your campaign audience will be much more focused.
Choose influencers with followers who are already likely to be intrigued by your brand and your products or services. That way, the campaign has a much higher chance of success.
Trust
One of the challenges of traditional digital advertising is getting customers to care about and trust your promotional content. After all, every brand’s ads say the products or services are great, and customers know that’s not always true. Why should they trust your ads?
Influencer marketing neatly skirts this problem because the influencer has opinions the audience regularly trusts. In fact, nearly 70% of customers say they trust recommendations from influencers over information directly from brands.
The influencers’ content about your brand essentially serves as word-of-mouth marketing. Think about it like a personal recommendation from a friend or family member. Since the audience already trusts the influencer, they’re much more receptive to sponsored content about your brand.
Search engine optimization (SEO)
Running influencer marketing campaigns can also help with your search optimization efforts. When your influencer partners post about your brand, they will typically also link to pages on your website, like product pages or specific landing pages. The influencer’s followers who are interested in your brand will click on the links, driving traffic to your website.
These quality backlinks can help your SEO efforts by making your website seem more authoritative. Search engines typically rank websites with high-quality backlinks higher in the search results, so influencer marketing can help make your brand more visible to customers searching online.
Cost-effectiveness
One of the most important metrics to consider before choosing any new marketing channel is its cost-effectiveness. Marketing budgets are limited, so you have to carefully select the channels you invest in.
Luckily, influencer marketing offers a strong return on investment, making it an appealing option for marketers trying to get the most out of their marketing budgets. Over 80% of brands find influencer marketing effective, with Instagram offering the highest return on investment (ROI) for influencer campaigns.
Understanding influencer marketing effectiveness
The effectiveness of influencer marketing depends on how you set up your campaign. Understanding your options and how influencer marketing works will help you create the most effective campaigns possible.
Types of influencers
There are many types of influencers, both on and off social media. They include:
- Celebrities: Famous people promoting products or services for brands is nothing new. Now, in addition to traditional sponsorships in commercials or print ads, celebrities can also work as influencers on social media by posting about brand partners. They have built-in audiences and recognizability from their work in their original fields, like acting, singing, or sports.
- Mega and macro-influencers: These influencers typically gain popularity on social media posting about a specific niche, like travel, gaming, or lifestyle content. Macro-influencers have between 100,0000 and 1 million followers, and mega-influencers have over 1 million followers.
- Micro-influencers: Micro-influencers have smaller audiences, between 10,000 and 100,000 followers on social media.
- Experts and industry leaders: People who establish themselves as experts or authorities in their field also gain audiences and can act as influencer partners for brands. They may have their own websites, newsletters, or other digital content where they can promote your products or services.
- Bloggers: Bloggers are people who post primarily written content on their websites. They can write about any topic, from food and recipes to fashion or fitness.
- Video content creators: These influencers share video content rather than text or image posts. Popular platforms for video content creators include YouTube, TikTok, and Facebook.

How and why influencer marketing works
When people discuss influencer marketing, they’re generally referring to paid influencer marketing. In those campaigns, you directly pay influencers to post about your brand according to the terms of your agreement.
There’s also earned influencer marketing, which is when influencers talk positively about your products or services without any financial incentive. They’re just promoting your brand because they genuinely like it and want their followers to know. Both types of influencer marketing should help your brand grow — you just have less control over earned influencer marketing.
Different social media platforms function differently, so make sure you tailor your influencer marketing strategy to the platform your influencers use. For example, audiences are more receptive to longer, more in-depth video content on YouTube than on Instagram.
Challenges and limitations in influencer marketing
Influencer marketing isn’t without its challenges. There are some bots and scam influencers online trying to steal money from companies interested in influencer marketing. They look good on the surface but don’t actually have any intention of posting about your brand once you pay them. The more you get to know potential influencer partners, the safer you will be from these scams.
If you partner with an influencer who behaves poorly, it could hurt your brand’s reputation. They reflect on you, so you need to choose carefully.
It’s also tricky to measure true engagement in influencer marketing campaigns. For example, someone might see your promotional posts and, as a result, buy one of your products in-store. That’s a successful sale from your campaign, but you have no way to effectively measure those types of conversions.
How to connect with the right influencers
Choosing the right influencers is a key factor determining the success of your campaigns. To make sure you find the ideal influencers for your brand, keep these tips in mind.
Identify your goals and objectives
Step one in any marketing campaign, including influencer campaigns, should be setting your goals and objectives. You need to know what exactly you want to accomplish with your campaign before you can start making any decisions.
Examples of goals you might have for your influencer campaigns include:
- Increasing brand awareness
- Boosting customer engagement
- Driving web traffic
- Enhancing your SEO efforts
- Building trust with your audience
- Increasing conversions and sales
Once you set your goals, you can choose influencers with those goals in mind. For example, if your goal is to drive web traffic, you should select influencers on platforms where they can add clickable links to their posts about your brand.
Know your audience
You also need to understand whom you’re trying to reach with your influencer campaigns. Who is your target audience? What do they like, dislike, and engage with online?
Use what you know about your target audience to find influencers who appeal to them. The best influencer partners for your brand are those whose audiences overlap significantly with your target customers.
Know your influencer
Audiences will associate your influencer partners with your brand, especially in long-term partnerships, so it’s important to choose carefully. You need to make sure the influencers you select are trustworthy and reliable representatives of your brand.
Digging into the influencers’ content also helps you craft a more personalized outreach message. Influencers often get many brand partnership proposals, so personalizing your message and showing you’re actually familiar with their content can help your brand stand out. It’s a good foundation for a strong influencer-brand partnership.
Consider engagement
Many brands just getting into influencer marketing are drawn to the most popular influencers with millions of followers. While partnering with these influencers does provide incredible reach for your brand, it’s not necessarily more effective than partnering with smaller influencers. For small and medium business owners, working with nano or micro-influencers is more budget-friendly and produces much higher engagement rates, making them appealing partners for brands. These influencers’ followers are more likely to like, share, and comment on their posts compared to mega-influencers.
Leveraging technology to optimize influencer marketing
Running an influencer marketing campaign involves a lot of steps, from finding influencers and reaching out to them to designing your campaign and monitoring the results. Using social media marketing tools can make that process much easier.
For example, there are online tools that suggest suitable influencers after you input your desired qualities. You can even find AI-driven influencer selection and performance prediction tools.
There are tools dedicated to managing and analyzing campaigns in each of the digital marketing channels you may want to use, including:
- Email marketing

- BlueSky
- TikTok
Within an influencer management tool, you can set up workflows to monitor each step of your campaigns, from outreach to payment. You can even create automated follow-ups, triggers, and notifications so you always know what’s going on without additional manual work.
Then, you may also want to use advanced tracking and analytics tools to get the full picture of your campaign results. They can monitor and display key metrics like engagement, reach, and conversions from your sponsored posts.
