Digital Marketing KPI Example - Return on Marketing Investment (ROI) Metric
Return on Marketing Investment (ROI) =
(Sales Growth – Marketing Cost) x 100 / Marketing Investment

Marketing ROI Key Terms

  • Leads: New prospects generated by a marketing campaign.
  • Incremental sales: New revenue generated by a marketing campaign (see "Incremental Sales").
  • Wins: New customers generated by a marketing campaign.

Marketing Return on Investment Example

Let’s say we have a company that averages 4% organic sales growth, and they run a $10,000 campaign for a month. The sales growth for that month is $15,000. The calculation goes:

Return on Marketing Investment = [($15,000 - $10,000) / $10,000)] x 100
= 50%

Return on Marketing Investment Success Indicators

  • Conversion rate: The percentage of visitors who complete a desired action on the website or landing page, such as making a purchase or filling out a form.
  • Customer acquisition cost (CAC): The cost incurred to acquire a new customer, which includes all marketing and advertising expenses.
  • Customer lifetime value (CLV): The total value a customer is expected to bring to the business over their lifetime, including repeat purchases and referrals.
  • Brand awareness: The level of recognition and recall that consumers have for a brand, which can be measured through surveys, social media mentions, and other metrics.
  • Engagement rate: The level of interaction and engagement that consumers have with a brand's content, such as social media posts, email campaigns, and blog articles.

By monitoring and analyzing these metrics, businesses can assess the effectiveness of their marketing campaigns and make data-driven decisions to optimize their marketing strategy and maximize their ROI.

Return on Marketing Investment Challenges

Despite the quintessential importance of marketing ROI, it can be difficult to measure and monitor. Measuring the ‘investment’ side of the equation is typically straightforward, you track hours spent planning and executing marketing campaigns and dollars spent securing advertising space online and offline. But measuring returns on marketing investment is more complicated for several reasons.

Numerous Campaigns

First, most marketers today run a wide variety of campaigns simultaneously. This can make it difficult to stay on top of spending and the performance of each individual campaign.

Lack of Control

Second, in our fast-paced digital world, marketing campaigns can take on a life of their own, and it can be difficult to monitor and measure the effects of marketing messages that are being spread by an external audience.

Seeing the bigger picture

Lastly, and in relation to the first two challenges, connecting the dots between marketing campaigns and the achievement of marketing goals can be challenging. Multiple marketing messages often reach a target audience through a variety of marketing channels: which one resonated? What call to action incited action?

Faced with these challenges, the most effective way to measure marketing ROI is to combine and compare data sets from a variety of sources (Google Analytics, Google Adwords, your Marketing Automation Platform, and CRM) to identify data correlations and trends over time. If you’re seeing that increasing your Adwords spend is consistently coinciding with a bump in website traffic and that the bump in website traffic is leading to more leads and more sales, you can break that conversion loop down and come up with a return on investment KPIs as straightforward as these:

  • New Website Users/Trial Start: 25
  • Adwords Spend/New Customer: $35

Return on Marketing Investment Best Practices

There are many possible ‘returns’ on marketing investments. A marketer might target ‘top of the marketing funnel’ returns such as increased brand mentions online or new website traffic. They may be interested in driving more leads through the middle of the funnel, by targeting new trial starts or new newsletter subscriptions, for example. Or they may be directly targeting the marketing goal that connects all others: new customers and new sources of revenue. Whether the marketing target is top of the funnel or bottom of the funnel, short-term or long-term, measuring marketing’s progress toward its goals against the time and money that has facilitated that progress is critical.
