Demand theory, as a fundamental principle of economics, has significant applications in digital marketing, as it helps companies understand how consumers react to changes in price, quality, and perceived value. This understanding enables businesses to craft precise marketing strategies that drive higher demand and optimize revenue.

Tools such as Google Ads and Facebook Ads allow for precise audience targeting and campaign customization according to specific market segments. With the help of A/B testing, which involves simultaneously displaying two versions of an ad or offer to different user groups, companies can analyze which approach yields better results. This method helps collect data on whether changes in price, ad design, or campaign content increase user engagement or sales.

Demand elasticity analysis is a process that measures how sensitively the market responds to price changes. These insights allow companies to predict whether a price reduction will significantly boost sales or whether luxury products can maintain high prices without losing customers. Based on these analyses, businesses can create targeted promotional activities, such as discounts, that generate the greatest impact on attracting new customers and increasing loyalty among existing ones.

By combining demand theory, elasticity analysis, and modern tools, companies not only adjust their offerings to market needs but also optimize marketing costs. This fusion of economics and marketing provides long-term advantages in a competitive environment.
