Celebrity women are absolutely dominating social media when it comes to personal branding nowadays, and Selena Gomez is the queen bee of digital buzz. According to measurement company D’Marie Analytics, the top six social influencers are either female pop stars like Gomez, Rihanna, Beyoncé and Taylor Swift—or their last name is Jenner, and first name is either Kendall or Kylie.

Gomez currently stands in the No. 1 slot and, per D’Marie, is worth $550,000 per social media post when the messaging appears across Facebook, Twitter and Instagram. That’s $300,000 more than the analytics company said Kendall Jenner, Gomez, Swift and Cara Delevingne could probably charge last December.

Frank Spadafora, CEO of D’Marie Group, described the methodology behind Gomez’s $550,000 figure: “The rate-per-post is her ‘ad equivalent’ value per post across Facebook, Twitter and Instagram. This may be different than how much she is actually getting paid when participating in social media campaigns. That is up to negotiations between her agents and the brands. This valuation is based on D’Marie’s algorithm which measures 56 metrics including followers, post frequency, engagement, quality of post, click-thru and potential to create sales conversions from her social content.”

While Gomez has deals with Coca-Cola, Pantene and Kmart, Spadafora said that she doesn’t endorse just any brand.

“It’s interesting that the statistically most influential person on social media is engaged in noticeably less campaigns than other celebrities,” Spadafora remarked. “Personally, I think it’s because she’s being smart and she’s aware that over-saturating her social feeds with sponsored content could negatively impact the relationship she has with her audience.”

Gomez’s audience is expanding by an average of 200,000 fans/followers daily on Facebook, Twitter and Instagram, according to D’Marie. It’s particularly staggering that the entertainer has nearly 90 million followers on Instagram alone, and she has almost 200 million fans/followers when adding Facebook and Twitter to the mix.
