To make influencers seem more authentic, just add #friends

“People want to feel a connection,” Ding says. “If you post your close social ties, people feel they can connect with you.”

With a Little Help from My Friends

Influencer marketing has exploded. In 2016, there were more than 1.2 million sponsored posts on the social media platform. By 2020, that number had nearly quintupled. Last year, companies spent more than $16 billion on influencer marketing strategies — no surprise, considering 60% of marketers believe this approach has a higher return on investment than traditional advertising.

Despite the frenzy, the field remains relatively unexplored, and researchers are just starting to understand the secrets behind influencers’ engagement. That’s changing quickly, though. “You have to work fast because this is a hot topic that companies are urgently seeking answers for,” Ding says.

To figure out whether including friends and family in posts really improves engagement, Ding and his coauthors analyzed data from Instagram influencers whose accounts were in the top 1,000 most followed. They sorted more than 55,000 posts based on whether the text mentioned a close friend, family member, or romantic partner, and by how many people appeared in each photo. Several social media–savvy research assistants checked a sample of the data to ensure these classification methods were sound.

This research found that posts that mentioned close social ties in their text received nearly 9% more engagement, as measured by likes per follower. That might not seem like a lot, but if you’re Portuguese soccer star Cristiano Ronaldo, that’s nearly 2 million more people interacting with your post. They also found that posts that pictured two to three people were the most popular.

Me and the boys: Researchers created simulated posts featuring a gamer with more than 7 million Instagram followers to see which one people found most likable. An image of him with two friends had the highest engagement.

To prove causality, the researchers conducted a series of experiments where they altered posts by influencers like actor and entrepreneur Jessica Alba and YouTuber David Cánovas Martínez to see which images and text engaged study participants more. These experiments proved that posts that reference influencers’ close friends, family members, and romantic partners do the best job of capturing likes.

Ding, Chung, and Kalra explored a few possible reasons why we’re drawn in by glimpses of influencers’ time with besties and loved ones. Sharing moments from real relationships can help influencers come across as more authentic, and we crave authenticity. These moments can also make influencers seem warmer and more relatable — think, “Stars — they’re just like us!” Lastly, as hypothesized by the researchers, humans are naturally nosy, and getting a window into influencers’ personal lives can be a tantalizing prospect.

Rules of Engagement

Ding says it would be a mistake if the lesson brands and influencers take away from this research is to always post photos with two to three people, captioned with mentions of family, friends, and partners. “We don’t want to give people a shortcut to game the system,” he says. “When you are trying to cast an image of your brand, of your product, what do your consumers value? You have to really understand that they value social connection and authenticity, especially in the context of influencer marketing.”

There is, of course, an inherent tension between feeling like someone is trying to share their life with you authentically and feeling like they are trying to sell you something. Ding’s research also found that when influencers include close social ties in their sponsored posts, it mitigates the negative response that followers often have to posts featuring product placement or branded content.

He plans to continue exploring these effects, including their possible downsides. For example, when social media personalities post misinformation alongside posts that show close friends, family, and romantic partners, is the audience more likely to engage with it? “What if they should not have engagement in a certain context?” Ding asks. Also, what happens if influencers and brands stretch this approach too far? Will it erode their authenticity, making fans feel manipulated? These are questions he’s asking as part of a broader research agenda focused on how people evaluate information and how entities build and lose trust.

Ding believes that social media has the power to bring people together. Even when brands are leveraging platforms and influencers for business purposes, “let’s still focus on the social connection part of anything that you’re going to do,” he says. “We don’t want business to become the enemy of organic enjoyment of life. In fact, marketing can contribute uniquely to this by understanding and reflecting what consumers truly value.”

Ding still posts a photo of that one tree when he gets to work. But now, he’ll sometimes add a second photo, like a shot of him catching up with a friend over breakfast. Those posts typically get more likes, which helps Ding feel more connected with his circle of followers. “I’m happy with that, being an authentic, relatable, warm, and sometimes engaging ‘influencer’ myself,” he says.
