Which of the following is an example of pull marketing?

Pull marketing refers to strategies designed to attract customers to a brand or product by generating demand. This method relies on customers actively seeking out information or products rather than being directly sent promotional material.

Using search engine optimization (SEO) to attract traffic to a website exemplifies pull marketing because it involves optimizing content so that it ranks higher in search engine results, thereby encouraging users to find and visit the website based on their search queries. This approach relies on the behavior of consumers who are looking for specific solutions or information, effectively "pulling" them to the brand.

In contrast, the other strategies listed in the options involve more direct approaches, where marketers push the message out to the audience rather than waiting for the audience to seek it out. This illustrates that pull marketing is fundamentally about creating an environment where potential customers can discover information on their own terms.
