¿Qué estadística se utiliza para medir la eficacia en campañas de anuncios patrocinados?

Return on Ad Spend (ROAS) is the most effective metric for measuring overall campaign efficacy because it directly quantifies the revenue generated for every dollar spent on advertising. This provides a clear picture of profitability and helps determine if the campaign is meeting its financial objectives. While Impressions, Click-Through Rate (CTR), and Sales are important metrics, they don't fully capture efficacy on their own. Impressions indicate reach but not engagement or revenue. CTR measures engagement but doesn't tell you about conversions or profitability. Sales show revenue generated, but without considering the ad spend, you can't determine if those sales were profitable. ROAS integrates both revenue and cost, offering a comprehensive view of campaign performance.
