Funnel: A funnel in marketing refers to the journey that a potential customer takes from their first interaction with your brand to the ultimate goal of conversion. It's often described as a funnel because many people will become aware of your business or product (the widest part of the funnel), but only a portion of those will move further down the funnel to consider your offering, and even fewer will proceed to the final step of making a purchase (the narrowest part of the funnel). It's crucial for businesses to study and optimize this process to increase conversion rates.
