Ad targeting is a marketing strategy that focuses on delivering advertisements to specific groups of people based on various criteria. This can include demographics like age, gender, and location, as well as interests and online behavior. By using data analytics, companies can identify potential customers and tailor their messages to increase engagement and conversion rates. There are several methods of ad targeting, including behavioral targeting, which tracks users' online activities, and contextual targeting, which places ads based on the content of a webpage. Effective ad targeting helps businesses maximize their advertising budgets by reaching the right audience at the right time.
