When marketers try to influence teenagers to buy their product what percentage of kids are they really marketing to?

When marketers target teenagers, they often focus on a specific segment of the demographic, typically around 10-30% of the teenage population, depending on the product and its relevance. This narrower focus allows brands to tailor their messaging and appeals to align with the interests and behaviors of the most likely purchasers. Additionally, teenagers are influenced by their peers, trends, and social media, which can amplify marketing efforts beyond the initial target audience.
