Growth Hacking: Growth hacking is a marketing strategy that focuses on rapid experimentation and data-driven techniques to optimize and grow a business's customer base or conversion rates. It often involves using low-cost and unconventional methods, such as social media, email marketing, or A/B testing, to identify the most effective marketing tactics and quickly achieve growth in user base or revenue. The primary goal of growth hacking is to adapt to customer needs and market changes quickly, maximizing the return on marketing efforts in a short period.
