Device targeting means showing ads differently on phones, computers, or tablets depending on user behavior. Many people searching on phones want quick answers, fast websites, or simple contact options like call buttons. Computer users may spend more time reading product details before buying anything. Because of this, marketers often create separate ad plans for each device type. Budgets may also change depending on where sales happen more often. A campaign doing badly on mobile may improve after changing the landing page or reducing mobile spending. Have you noticed businesses designing ads differently for phone users compared to desktop users?
