There have been numerous successful examples of influencer marketing campaigns that have generated significant results for brands. However, it is important to note that the specific results will vary depending on the brand, the product or service being promoted, and the influencer or influencers involved. Here are a few examples:

1. Kylie Jenner x Snapchat:

   In February 2018, Kylie Jenner tweeted that she was no longer using Snapchat, causing the app’s stock to drop by 7% ($1.3 Billion). Kylie’s tweet was seen as having a significant impact on Snapchat’s shares because she is a highly influential celebrity with a large social media following, and many of her fans take cues from her about what products and platforms to use.

   At the time, Snapchat was already facing growing competition from other social media platforms, such as Instagram, and Kylie’s tweet was seen as a further sign of the app’s declining popularity. The drop in shares was a wake-up call for Snapchat, which led to a redesign of the app and other changes aimed at improving the user experience and increasing user engagement.

   This demonstrated the power of influencer marketing and the impact that a single influencer can have on a brand.

   

2. Dior x Bella Hadid:
