Why Does Celebrity Endorsement Sometimes Overshadow the Brand?

A familiar face can make an advertisement impossible to ignore. Whether it is a film star promoting a skincare product or a cricketer endorsing a financial service, celebrities bring attention, recognition and a certain degree of credibility to brands. For marketers, this can be a powerful way to reach audiences and influence purchasing decisions without spending years building familiarity.

However, there is a catch. Sometimes, people remember the celebrity, the outfit they wore, or the line they delivered, but struggle to recall the brand behind the advertisement. This is one of the central challenges of Celebrity Endorsement. While a famous personality can make a campaign more memorable, that attention does not automatically translate into stronger brand recall or a reason to buy the product. The real challenge is ensuring that the celebrity helps communicate what makes the brand valuable rather than becoming the entire story.

Celebrity Endorsement: When the Star Becomes Bigger Than the Brand

This phenomenon is often described as the vampire effect, where a celebrity attracts so much attention that the advertised product struggles to compete for the audience’s attention. Research discussed by Wharton found that consumers were more likely to choose products endorsed by celebrities than those promoted by non-celebrities in the study. However, participants also tended to focus on celebrity faces rather than consistently following their gaze towards the product. The findings reveal an interesting tension: a celebrity can influence a consumer’s decision while simultaneously drawing attention away from the brand itself.

This is where the distinction between attention and brand building becomes important. An advertisement can generate millions of views, social media conversations, and positive reactions to a celebrity without giving consumers a clear understanding of the product’s benefits. If the audience remembers the famous face but forgets the brand name, the campaign may have created entertainment value without delivering its full marketing potential.

The problem becomes more pronounced when the celebrity’s personality is more distinctive than the brand’s identity. Consider an advertisement in which a popular actor’s humour, expressions, or screen presence dominate every scene. People may discuss the actor’s performance, recreate the dialogue or share the video with friends. Yet, if the product has little meaningful role in the story, the brand becomes an incidental part of an otherwise entertaining advertisement.

That does not mean celebrity-led advertising is ineffective. Familiarity, admiration, and social influence can help shape consumer preferences, particularly when people have not formed strong opinions about a product. The challenge is that these advantages do not automatically build lasting brand associations. A celebrity may encourage someone to consider a product, but the brand still needs to give that person a compelling reason to choose it.

The choice of celebrity, therefore, matters as much as the celebrity’s popularity. A study published in the International Journal of Research in Marketing examined the vampire effect through experiments involving 4,970 respondents. It found that a strong connection between the celebrity and the brand, along with a clear association between the two in consumers’ minds, could help reduce the risk of the celebrity overshadowing the product.

This explains why brands should look beyond follower counts, box-office success, or sporting achievements when selecting an endorser. The partnership needs to make sense to the audience. When a celebrity’s public image aligns with a brand’s values and offering, the association can feel more natural and memorable. When the connection feels forced, consumers may struggle to understand why that particular person is promoting that particular product.

There is also the problem of overexposure. When a celebrity endorses several unrelated products, the individual may become more recognisable than any single brand they represent. The endorsement can begin to feel transactional rather than meaningful, making it harder for a brand to establish a distinctive identity. As Botree Communications points out, celebrity partnerships require careful selection, alignment and management to deliver their intended value.

The answer is not necessarily to stop using celebrities. It is to give them a more purposeful role in the campaign. The product’s benefits, the brand’s distinctive qualities and the reason for choosing it should remain central to the story. Creative execution matters, too. If the celebrity interacts meaningfully with the product rather than simply appearing alongside it, the audience has a clearer reason to connect the two.

Ultimately, Celebrity Endorsement works best when fame strengthens the brand’s message instead of replacing it. Recognition can bring people to an advertisement, but a clear value proposition gives them something worth remembering. Brands should measure success not just by how many people notice the celebrity, but also by whether consumers recall the brand, understand its promise, and consider buying its products. After all, the purpose of an endorsement is not simply to make a star shine brighter. It is to make the brand more meaningful to the people it wants to reach.
