The advertising funnel, also known as the marketing or sales funnel, is a model that describes the different stages a potential customer goes through before making a purchase. The stages of the advertising funnel typically include:

1. Awareness: At this stage, the customer becomes aware of a brand or product through advertising, social media, word of mouth, or other marketing efforts.

2. Interest: After becoming aware of the brand or product, the customer shows interest and begins to actively research and gather information about it.

3. Consideration: At this stage, the customer has a strong interest in the product or service and begins to evaluate it against other options in the market.

4. Intent: The customer has decided to purchase the product or service and is in the process of making a final decision.

5. Purchase: The customer makes a purchase and becomes a customer of the brand or product.

6. Loyalty: After the purchase, the customer may become loyal to the brand and purchase from them again in the future, becoming a repeat customer.

It’s important for businesses to understand each stage of the advertising funnel in order to create effective marketing strategies that can move potential customers through each stage towards a final purchase.
