Crowd marketing is a marketing strategy that involves leveraging the power of the crowd or a group of people to promote a product, service or brand. In this approach, companies encourage their customers or social media followers to share their experiences, reviews, and opinions about their products or services on various online platforms such as social media, forums, and review sites.

Crowd marketing is based on the idea that people trust the opinions and recommendations of their peers more than traditional advertising. By encouraging customers to share their positive experiences, companies can generate buzz and create a positive reputation for their brand.

Some examples of crowd marketing strategies include referral programs, user-generated content campaigns, and influencer marketing. It can be an effective way to build brand awareness, increase engagement, and drive sales, especially in today's digital age where social media plays a significant role in shaping consumer behavior.
