What example illustrates a keyword's use in marketing?

The choice that illustrates a keyword's use in marketing focuses on the practice of optimizing content with specific terms, which is essential in digital marketing. Keywords are specific words or phrases that potential customers use when searching for products or services online. By incorporating these targeted terms into various forms of content—such as website copy, blog posts, and social media updates—marketers can improve their visibility in search engine results and attract more relevant traffic to their website.

Optimizing content with keywords helps to align offerings with consumer search behavior, making it easier for the intended audience to find what they are looking for. It plays a critical role in search engine optimization (SEO), where appropriate keyword usage can significantly impact a site's rankings and discoverability.

The other options describe activities within the marketing field, but they do not specifically highlight the function of keywords in driving visibility and connection with the audience. A brand launching a new product is a promotional strategy, a report on customer demographics deals with data analysis, and a manual for using marketing software addresses operational guidance, none of which pertain directly to the strategic use of keywords in marketing efforts.
