Have you noticed how many brands are prioritizing creator marketing lately? If you feel like you're drowning in social media posts by creators—both big and small—you're not alone. It can get overwhelming. But as you sift through the noise, it's important to remember that these creator partnerships can help your business grow.

Still, if you're looking to make the most of your creator marketing strategy, it can be challenging to know where to begin. That's where case studies come in. Reading through influencer marketing case studies can help you identify your goals, how to reach them, and what success looks like.

This guide teaches you how to leverage creator partnerships to grow your LinkedIn and X accounts with organic engagement. Creator marketing can help you reach your audience and diversify your content so you can get off the algorithm's naughty list.

One way to boost your efforts is with Megaphone's viral on-demand platform. This tool helps you find the right creators for your business to kickstart your organic growth quickly.

Benefits of Influencer Marketing

Amplifying Brand Visibility: The Potential of Influencer Marketing

One of the most notable benefits of influencer marketing is that it can help increase brand awareness. As influencers create content featuring your products, increased brand awareness will inevitably grow among their followers. This is especially helpful for new ecommerce businesses that don’t have an engaged audience. It’s also a fantastic way to create hype around a new product or collection launch.

For instance, Athletic Greens used TikTok influencers to spread awareness of their nutritional supplements among health-conscious Gen Zers. These social media influencers created content that showed how the supplement can become a part of their audience’s daily routines.

The campaign’s success speaks for itself. The hashtags #athleticgreens and #athleticgreenspartner have over 90.6 million views and 39.5 million views, respectively.

Market Expansion Through Influencer Partnerships

Influencer marketing can help you find untapped markets and reach wider audiences. Take the food brand King's Hawaiian, which partnered with creators to create its #foodtok. They worked with 16 creators who produced slider recipes for 'Slider Sunday' using the brand's delicious sweet bread. They used hashtags like #mealinspo to reach new viewers.

The key lesson here is to identify and collaborate with relevant influencers whose social following overlaps with the niche audiences you’re trying to reach.

The first step to encouraging sales through your social media? Build an engaged social following with influence marketing. As influencers talk about you and get their audience's interest in your brand, followers will likely follow you, too. This will hugely benefit your social media marketing efforts. Partner up on some giveaway campaigns with your social media influencers. The trick of asking people to follow your brand in return for a chance to win a gift will work a charm. After all, everyone loves a freebie.

Gaining Valuable Insights Through Influencer Marketing

You can also use influencer marketing to source feedback on a new product, collection, or product feature. Because many influencers engage with specific niche audiences, they’ll have valuable insights into what your ideal buyers look for in a product. Plus, they can share detailed feedback by trying your products for themselves.

Feminine hygiene company Thinx did just that. They invited 25 influencers for a slumber party event in Los Angeles to get feedback on their new athleisure line. Thinx used the information they gathered to launch clothing their consumers would be interested in, and grew their sales by giving influencers unique discount codes. This led to $810,000 in revenue with a per-customer acquisition cost of $35.20.

Building Trust and Credibility With Your Audience

Content that talks positively about your brand can help you build a good reputation and is essential for enhancing brand awareness. As influencers discuss you and endorse your products, you’ll slowly build trust with your target audience. Skin + Me uses influencers and user-generated content (UGC) in their Facebook ads. From people unboxing their products to before and after videos to show how their skin has improved after using their products — this is sure to build trust and credibility with their target market. This tactic has worked so well that customers often post their own before and after pics in the comments section showing the improvements they saw in using their products. This just adds to the positive perception of your brand when customers are making purchasing decisions.

Boosting Sales and Repeat Purchases With Influencer Marketing

Influencers can help increase sales directly as they share discount codes or recommend your product and indirectly as your brand awareness grows. Intimates brand KNIX collaborates with influencers for this reason — using custom discount codes to drive sales. For example, influencer Hilary Henderson promotes Knix's products via her Instagram page.

You can grab her discount code, HILARYHCOMEDY_KNIXLOVE by checking the post descriptions. Every influencer has a different code, so when someone uses it in their online store, it's easy for the team at Knix to know which influencer has had the most impact. Moreover, if your current customers see their favorite influencers share content about your products, they'll feel encouraged to place repeat orders.

Fresh Content Creation for Your Brand's Marketing Initiatives

Creating new and creative ideas is part of the job of a marketer. But it can get tiring having to continuously think of new ideas, especially if you're a small team. Experienced influencers can bring fresh, out-of-the-box marketing ideas to the table. They'll have a new perspective on your brand and can offer creative ways to promote your product - with little effort on your part.

To find influencers or manage your campaigns, look at our list of influencer marketing tools ideal for small and growing brands.

Cost-Effective Marketing With Micro-Influencer Partnerships

Another benefit of influencer marketing - and one your boss will love - is that it can be cost-effective. Running influencer campaigns is 30% cheaper than most advertising and marketing strategies. For this very reason, Doe Lashes‘ founder, Jason Wong, chose influencer marketing over other paid ads for the first 4 months of his brand’s launch.

Jason found that sending a shipment of lashes to micro-influencers would cost less than $10 per shipment. And if he made even one sale from an influencer, he’d break even. If he got 2-3 sales, he’d profit and slowly start gaining traction. This is precisely what happened. One month of influencer marketing led to $2.6K in daily sales by effectively reaching niche audiences!

Educating Buyers About Your Products

A non-salesy way to market to potential customers is by educating them on how to use or style your product — depending on what you sell. By thoroughly briefing influencers about your product, you can allow them to create content that educates their target market about your product in an engaging manner. Not only does this help grow your sales, but it encourages customers to create user-generated content featuring your product. This, in turn, gives you more exposure and grows brand awareness.

Take a page from Supergoop's TikTok influencer marketing campaign. The sunscreen brand reached its ideal audience by pairing with influencers in fashion, lifestyle, and beauty niches. Their influencers made creative content that highlighted Supergoop sunscreen's features in a light-hearted and entertaining way. This aligned with the brand's voice and educated the influencers' followers on the importance of wearing sunscreen. They also showed how Supergoop's clear SPF50 differed from the traditional, white-cast sunscreen people are used to.

Building a Bank of Content for Repurposing

Finding time to create high-quality content can be challenging if you're a small or growing marketing team. You're already busy with product shots, banner ads, email campaigns, etc. Working with influencers means that content is created for you, and you can repurpose it across your campaigns and channels. Brands like Starface, for example, use pieces of content created by their customers to enhance their checkout.

Using real people will add a personal touch to your brand's online store, which helps reduce friction when they're getting ready to buy. However, you'll need to keep track of contracts and image usage rights. If you have content from last year's campaign, it is essential to determine if you have permission to reuse it the following year. Using content without permission can lead to severe brand damage.

Collecting Data to Understand Your Audience Better

Next on the list of influencer marketing benefits is the advantage of collecting data about your niche audiences. As gathering third-party audience data becomes harder, working with influencers can help you source audience data. The more data you have, the easier it is to create better and more audience-relevant marketing content. Your influencer will have data on audience demographics.

That’s age, gender, and location — broken up into the different social platforms they work on. They’ll also be able to tell you about the engagement, reach, and impressions their posts get. This will be useful in understanding how well your campaigns are going and whether they resonate with their audience. For direct sales attribution, it’s worth setting up tracking codes to see who’s clicked through to your website and checkouts.

You’ll need to give this to your influencer before they start the campaign. Remember that not all influencers are open to sharing their audience analytics. Building long-term relationships with influencers can often lead to them giving you access to their demographic data from social media platforms and any other tools they use. This, in turn, helps you make better-informed, data-driven decisions.

Collaborating With Experts to Enhance Brand Authority

If you have good brand authority, your customers view you as the subject-matter expert in your industry. Growing your brand authority will increase brand awareness and give you a better chance at helping prospects overcome objections. To increase brand authority and focus on enhancing brand awareness, you could interview experts as part of your content strategy, create a podcast, run webinars, and be a guest on other people’s platforms.

You could also enlist the help of an expert influencer. This is something one of our customers, Forthglade, does well. As a dog food brand, they know their customers only want the best products for their furry friends. So, as well as providing lots of tips on their blog, they work with different types of influencers like Dr. James Greenwood on their social media platforms to provide accurate, expert advice on looking after and caring for your best friend.

Creating Brand Ambassadors From Influencer Partnerships

Another key benefit of influencer marketing is the opportunity to build long-term partnerships with your content creators, leading to increased brand awareness. If they try out your products and genuinely love them, they’re more likely to post about them organically and recommend them to friends and people outside their following.

Just look at this case study from Grin, who helped an online brand, Inkbox, create an influencer campaign to build a community of brand ambassadors. They got 70+ creators to post about their products across different marketing channels. This, in turn, created a 40% uptick in unprompted creator posts. If you can cultivate genuine connections with your influencers, you can turn them into loyal brand ambassadors.

Strengthening Your Online Community with Influencers

Online communities are fantastic places for like-minded people to connect, chat, swap tips, and share advice on particular topics. Communities mainly flourish on social networks, which makes them a great place for brands to build connections with their customers. (Look at big brands like Gymshark and GoPro to see what we mean.) But creating a sense of community isn’t easy. You must establish a loyal customer base, a good online following, and an emotional connection with your audience. This is where influencers can help.

Take Lick, a UK-based paint brand. They took a slightly different approach and encouraged their Director of Interior Design to be their ‘internal’ influencer. Having this regular face show up on socials is essential in building a strong bond with their community. Amie, Head of Social Media and Creators at Lick, says: “It's nice for our community to know that there are real people at Lick, like Tash, who’re there to give our decorators help and advice on particular topics. This is important for our brand values as well. It's also given us a unique way to lean into video content across our key platforms like Instagram and TikTok. Plus, Tash creates the colors, so who better tell our community about them than the person who makes them?

Generating Quality Leads with Influencer Marketing

As we mentioned, 82% of brands say they see better ‘quality’ leads from influencer marketing campaigns over any other campaign, especially when targeting niche audiences. That’s quite an impressive stat, and after learning about the influencer marketing benefits in this post, you can see why. By partnering with influencers who talk about your specific niche, you can reach a loyal audience that’ll be genuinely interested in your products.

2. Establish Your Objectives and Tone

Before reaching out to potential influencers, define the goals you want to achieve and how you will reach them. The most popular reasons for implementing influencer marketing are to raise brand awareness and increase sales. The great thing about working with influencers is that they reach very niche audiences, often making it a more effective strategy to reach new potential customers.

Once your goals are set, you’ll want to work on messaging. The best way to engage an influencer’s audience is to let the influencer be themselves, but you don’t want to give them complete free reign to say whatever they want. Determine key messages for the influencer to include in their post to keep your campaign on track.

3. Identify Your Ideal Audience

This tip isn’t unique to influencer marketing. However, knowing your target audience will help identify relevant influencers to work with much more straightforwardly. Because influencer followings are so niche, verifying that their audience is also your audience is essential to ensure you get a return on investment. Oftentimes, the influencers themselves will align with your target buyer persona.

4. Compile a List Of Influencers

The key to driving a successful influencer marketing campaign is identifying relevant influencers who share your target audience to promote your brand or product. Just like public relations professionals must do their research to identify the appropriate reporters and producers to pitch, you’ll want to take your time finding the right influencers who share your target audience. Experienced influencers will have a media kit to share with you, breaking down their audience demographics, reach, category of content, and compensation expectations.

When deciding on influencers, you should determine how much their audience trusts them. A large follower count is great, but you might not achieve your goals if those followers don’t engage with the influencer’s content. Therefore, looking at an influencer’s engagement rate is a must. High numbers of views, likes, comments, and shares any influencer receives on their posts are significant indicators of a healthy engagement rate.

5. Pitch Your Brand

Reaching out to influencers about a possible partnership looks like public relations pitching. Many influencers will provide an email address on their social media accounts, but reaching out via direct messages is common. When you’re ready to inquire about a partnership, sending a personalized message to each influencer will increase the likelihood of a response. Compliment their content and tell them how much it would mean to work with them, but try not to come off as too sales-y.

Your pitch should include as much information as possible about your brand, the campaign you’re recruiting them for, and how working with you will benefit the influencer beyond the flat rate. Are you willing to send them free products? Will you provide an affiliate link from which they can receive a commission? These are all things to quickly note in your pitch.

6. Always Review Content Before it’s Published

While you should give influencers creative freedom to make the content look and sound like them, reviewing the images, videos, and copy before they’re published online to ensure they align with your brand messaging and campaign requirements is essential.

How to Find Influencers for Marketing

1. Discover Influencers with Megaphone

Megaphone is a sophisticated platform that connects brands with influential creators for marketing campaigns. Use Megaphone to discover niche-specific creators and start your next marketing campaign with the right influencer.

Social media is a goldmine for discovering influencers, especially if you’re searching for creators in your niche. First, check for any trending posts in your industry. If you notice a post going viral, see who published it and whether they have a substantial and active following. Also, look at the comment section of a popular post to see if any influencers are engaging with it.

If you’re looking for LinkedIn influencers, search for a relevant keyword and set the filter to ‘Posts.’ Scroll through the results and look for posts with a high level of engagement (i.e., likes, comments, views, etc.). A lot of engagement is usually an indicator that someone has a large audience.

3. Use Hashtags to Find Influencers

Use social media platforms’ search functions and look up keywords and hashtags related to your products or services to find influencers already creating relevant content. For example, an ethical clothing brand looking for TikTok influencers might check out the platform’s #sustainablefashion hashtag. If you’re looking for Instagram influencers, use location-specific hashtags to find influencers in your area. Try a combination of your location, niche, and words like ‘influencer,’ ‘creator,’ ‘blogger’ or ‘vlogger’ — like #atlantamomblogger.

4. Analyze Your Competitors

Are your competitors working with influencers? While you might want to use different talent, check out their influencers’ audience and who they follow to find similar creators. Also, keep an eye on who gets a lot of likes or comments on your competitors’ posts, as they could be influencers.

5. Use Search Engines to Find Influencers

Try using Google to search social media sites. Here’s how: Type “site:” followed by the website name you’re searching. Follow the website name with a single space and then type the search phrase. If you wanted to search for a beauty influencer in Detroit, you’d type the following into the search field: site:instagram.com “detroit beauty blogger.”

A search like “your industry + influencers in X region” will help you find local influencers. You might also see some articles with lists of the best influencers in that region. For instance, if you’re a San Francisco-based cookware brand, a simple search for ‘Bay Area food influencer’ generates millions of hits.

6. Ask Your Network for Recommendations

One of the easiest ways to find an influencer is to ask for recommendations. Contact your network—colleagues, employees, friends, industry contacts, business partners, etc.—and see if they know any influencers that would fit your criteria. You could also post about your influencer search on social media. Encourage your network to recommend or tag potential influencers in the comments and share or like the post to help boost its reach.

7. Connect with Influencers at Industry Events

Influencers may work online, but you can still personally connect with potential partners at events and conferences. Try attending creator-specific events like VidCon or CreatorConf to discover new influencers and gain tips and inspiration to optimize your next campaign. Don’t you have the budget to participate? Look up some events and conferences in your industry and see who’s speaking at them. Event organizers often hire influencers as speakers as their sizable audiences will attract attendees.
