Measuring performance isn’t optional—it’s essential. Key Performance Indicators (KPIs) provide the metrics needed to gauge campaign effectiveness, optimize strategies, and justify marketing investments. Let’s explore the most important KPIs in digital marketing and how they can drive your success.
Why You Need KPIs
The old business adage “you can’t improve what you don’t measure” couldn’t be more relevant in digital marketing. KPIs serve as your navigational tools in the vast digital landscape, offering several critical benefits:
- Direction and focus: KPIs align your team around specific goals instead of vague aspirations. When everyone knows what metrics matter, they can prioritize activities that move these numbers.
- Data-driven decisions: Guesswork has no place in modern marketing. KPIs provide objective data that helps you allocate resources toward what’s working and pivot away from what isn’t.
- Performance visibility: Well-chosen KPIs offer a clear picture of campaign performance at a glance, making it easier to communicate value to stakeholders who may not understand marketing technicalities.
- Continuous improvement: Tracking KPIs over time reveals trends and patterns, enabling ongoing optimization rather than periodic, reactive changes.
Without KPIs, marketing teams operate in the dark—spending budget without clarity on return and missing opportunities to improve performance incrementally.
KPIs Built into Most Ad Platforms
Today’s advertising platforms understand the importance of measurement and provide robust analytics dashboards with key metrics already calculated for you:
- Impressions and Reach: These metrics show how many times your ad was displayed (impressions) and to how many unique users (reach).
- Click-Through Rate (CTR): The percentage of people who clicked your ad after seeing it. Low CTR often indicates that your creative assets or targeting need improvement.
- Cost Per Click (CPC): How much you pay, on average, for each click on your ad. This metric helps evaluate the efficiency of your bidding strategy.
- Cost Per Mille (CPM): The cost per thousand impressions, useful for brand awareness campaigns where exposure matters more than immediate action.
- Conversion Rate: The percentage of users who completed a desired action after clicking your ad, such as making a purchase or filling out a form.
- Return on Ad Spend (ROAS): Revenue generated for every dollar spent on advertising—a direct measure of campaign profitability.
- Quality Score (Google Ads): Google’s rating of ad quality and relevance, affecting both ad position and cost.
- Engagement Rate: On social platforms, this measures interactions like comments, shares, and saves relative to reach.
- Video View Rate: For video ads, the percentage of the video that users watched before dropping off.
These built-in KPIs offer immediate feedback on campaign performance and allow for quick optimizations within the platform.
KPIs You May Need to Calculate Yourself
While platform-provided metrics are valuable, they often tell only part of the story. If your sales or other lead activity happens somewhere off of your website, you may want to calculate your own KPIs that map on-page conversion (soft conversions) to off-page conversions (sales). This requires some additional calculations but can be well worth it. Some marketing platforms and CRMs like HubSpot allow direct integration, enabling you to automatically collect this info.
Here are some crucial custom KPIs to consider:
- Customer Acquisition Cost (CAC): The total cost of acquiring a new customer, including all marketing and sales expenses. This comprehensive metric goes beyond platform-specific costs.
- Customer Lifetime Value (CLV): The total revenue a business can expect from a customer during their relationship. Comparing CLV to CAC reveals whether your acquisition strategy is sustainable.
- Lead-to-Customer Conversion Rate: The percentage of leads that eventually become customers, revealing the effectiveness of your sales process after marketing hands off leads.
- Multi-Touch Attribution: Assigning value to each touchpoint in the customer journey, providing insight into which channels influence purchases most significantly.
- Marketing Qualified Leads (MQLs) to Sales Qualified Leads (SQLs): Tracking how many marketing leads meet sales team criteria shows marketing-sales alignment.
- Time to Conversion: How long it takes prospects to move through your funnel, highlighting potential friction points.
- ROI by Channel: Comparing the return on investment across different marketing channels helps optimize your channel mix.
These more sophisticated KPIs require integration between your advertising platforms, website analytics, and CRM system. However, they provide deeper insights that can substantially improve resource allocation and strategy.
By combining platform-provided metrics with your custom KPIs, you can develop a comprehensive view of marketing performance from initial awareness through customer retention and advocacy. The right mix of KPIs will vary by business model and goals, but the principle remains constant: measure what matters, and let data guide your digital marketing decisions.
