The theory

Understanding Marketing Effectiveness.

Effective marketing is about spending money to make more money. To know if you're succeeding, you need to track key metrics that connect your spending to your revenue.

/ Formula

Return on Ad Spend (ROAS): Revenue from Campaign / Marketing Spend. This shows you how many dollars you get back for every dollar you spend. A ROAS of 5x means you earned $5 for every $1 spent.

Cost Per Acquisition (CPA): Marketing Spend / Total Bookings. This tells you how much it costs, on average, to acquire one new booking from a specific campaign. A lower CPA is generally better.

Questions, answered

Frequently asked questions.

This requires proper tracking setup. For digital ads (Google, Meta), use conversion tracking pixels. For email, use UTM parameters in your links. For offline ads (like print), use a unique promo code or a dedicated landing page URL to attribute bookings.
Industry benchmarks vary, but a common target for hotels is between 8x and 12x. However, this depends on your profit margins. A 4x ROAS can still be profitable if your margins are high. The key is that your ROAS must be higher than your break-even point.
No, they are different. ROAS specifically measures the return on ad spend, looking at gross revenue. ROI (Return on Investment) is a broader metric that considers the profit, not just revenue, and includes all costs, not just ad spend. ROAS is a tactical metric for campaign performance, while ROI is a strategic metric for overall profitability.
To lower your CPA, you need to either spend less to get the same number of bookings, or get more bookings for the same spend. Focus on improving your ad targeting, refining your ad copy and creative, and optimizing your website's booking engine to make it as easy as possible for guests to convert.
Not necessarily without further analysis. Some campaigns, especially at the 'top of the funnel,' are designed for brand awareness, not direct bookings. Their goal is to introduce people to your hotel. While their direct ROAS may be low, they may be assisting conversions that happen on other channels later. Consider using attribution models to see the full picture.
