Only then you are credible…
I almost wanted to start with: “You cannot trust product tweets of celebrities…” But if that would be a surprise to you, I have some other shocking news to you: Santa doesn’t exist. However, if everyone knows the tweets are set up by the brands themselves, and the celebrities are paid for such tweets, why would brands still spent million dollars to celebrity social media product endorsement?
Opendorse did research to those product endorsement tweets: a tweet from Cristiano Ronaldo is valued $304.000(!) (See source beneath for more numbers). Note that this is the actual value of the tweet for the brand itself, so it does not say celebrities are really paid that amount.
As we know that those tweets are valuable and that it does not matter that we, actually, all know that those tweets are not “real”, what makes the “fake opinion/tweet credible to us, the consumer. That is what Jin and Phua investigated in 2014: “ Explicate the conditions under which celebrities can be leveraged as effective catalysts for brand-related E-WoM on Twitter.” They created semi-fictious celebrity twitter pages, where after they let students (east coast of US) fill in a questionnaire based on these profiles (which off course included a product endorsement tweet).
Jin and Phau found that high numbers of followers results in higher credibility of the celebrity (more physical attractive, trustworthy and competent). On top of that, positive brand tweets of a celebrity with a high number of followers results in higher product involvement/buying intention. This effect is strengthened in case of a prosocial celebrity. In contrast, a celebrity with a low number of followers does not effect product involvement.
(In order to differentiate between types of celebrity (prosocial/antisocial), participants read an article of the celebrity either engaged in charity work or involved in drug abuse and/or adultery scandal.)
On top of that, it is interesting that “we” are more willing to share a tweet if it is coming from a celebrity with a low number of users and if it is negative about a specific brand/product. Probably because we think that a tweet from someone with a high number of followers will be not new to our own followers.
Concluding, celebrities are more credible than ordinary users towards twitter users. If a brand wants to start with twitter celebrity marketing, they need to focus on the number of followers (not only because of the reach, but also because of the credibility) and the behavior of the celebrity. Maybe it would be even better to contact a not that well-know celebrity and let him upload a negative tweet about a competitor. It will be shared more often by other twitter-users, and then it will maybe get more attention.
However, we must not forget that a celebrity, who will promote a lot of products using twitter, will be less credible in the end. Besides, I doubt if everyone knows how much followers his or her followers have.
Then I got one last question to you: if you had to set up one celebrity tweet for Microsoft surface tablet, who would tweet what text, and tell me why? Besides, tell me why this tweet didn’t worked out well:
In turn I got one tip for Santa to be credible for old and young again: Open a twitter account and dramatically increase your number of followers… You are already famous!
Note: If you didn’t see Oprah’s mistake, take a look with what device she uploaded the tweet.
