5 Important Metrics for Your Digital Marketing Goals

Successful marketing leaders know that strategic budget planning starts with focusing on the right metrics. In today's data-rich environment, the key to optimizing your marketing investment isn't tracking everything—it's identifying which numbers truly drive business growth. Finding the right metric can sometimes feel like finding a needle in a haystack.

The most impactful marketing metrics connect directly to your bottom line: pipeline and revenue. By centering your strategy around these business-critical indicators, you create a framework for both accountability and opportunity.

Tracking targeted metrics gives you the clarity to make confident budget decisions, allocate resources effectively, and demonstrate marketing's contribution to company objectives. With the right measurement approach, you'll gain valuable insights that help you adapt to changing market conditions while keeping your marketing initiatives aligned with long-term business goals.

Let's explore five key metrics that can transform how you optimize your digital marketing budget:

1. Short-term Revenue Perspective: ROAS (Return on Ad Spend)

ROAS offers an immediate view of campaign performance, tracking how much revenue you generate for every dollar spent on advertising. While valuable for efficiency measurement, ROAS has important limitations that marketing leaders should recognize.

ROAS is expressed as a ratio, percentage, or multiple. For example, if you spend $1,000 on Google Ads and generate $5,000 in sales, your ROAS is 5x (or 500%).

Why ROAS matters but isn't enough:

ROAS provides a short-term view that can be misleading when used as your only metric. An e-commerce company solely optimizing for ROAS might see apparently strong results while actually hampering growth. This happens because advertising platforms naturally start optimizing toward warmer, higher-converting traffic—often targeting existing customers instead of net new customers. While that makes media efficiency look great, it may be at the expense of growing the pipeline and acquiring new customers.

Strategic application:

• Segment campaign audiences clearly based on previous behavior with the brand (new vs. returning customer, prospecting vs. retargeting, etc.). This allows you to evaluate ROAS within the context of the customer value.
• ROAS is most beneficial when evaluating campaigns driving direct sales. Mid or high funnel tactics will typically see lower ROAS and should be evaluated separately.
• ROAS is impacted by all other elements of your marketing mix. Increasing TV spend or implementing a big direct mail campaign can drive down funnel ROAS in digital platforms. Be mindful of your entire media mix when evaluating specific channel tactics.

2. Long Term Value Perspective: Customer Acquisition Cost and Customer Lifetime Value

Customer Acquisition Cost measures the total cost of acquiring customers, including marketing and sales expenses. Unlike ROAS, which focuses on immediate return, CAC, sometimes referred to as NCAC (New Customer Acquisition Cost), helps you understand the investment required to bring new customers into your business.

The formula: CAC = Total Marketing & Sales Spend ÷ Number of New Customers Acquired.

But that only tells part of the story. The other key metric is the lifetime value of that customer. Every business has different customer values and buying behavior. A B2B company serving niche professionals might have large monthly orders and customers that are retained for decades, while a moving company may only expect to help that customer make one or two moves in their lifetime.

Understanding the value of your customer lets you put the acquisition cost into perspective. A customer base with a lower lifetime value should target a lower acquisition cost – alternatively, customers with high lifetime values might be willing to target higher acquisition costs (even to the point of being initially unprofitable for the first purchase) if it means significantly longer value down the line.

Strategic application:

• Use your LTV to understand profitable and scalable customer acquisition costs.
• Compare CAC across channels to identify your most cost-effective acquisition sources.

3. Understanding Repeated Visibility: Frequency

Frequency, or how often your ads are shown, is an important consideration for channel budget planning and effectiveness. Show ads too much and customers will get bored and tune out the noise; show them too little and your brand is ineffective.

Frequency (or in Google platforms, Avg. Impressions per User) lets you understand exactly how many times people were exposed to your ads. Combine that with your business KPIs (ROAS, Cost/Conv, etc.) and you can typically spot the point of diminishing returns.

For some attribution models, conversion rates appear to improve, without actually driving a lift to the business bottom line. That's because repeated exposure within a view-through window can inflate platform-reported conversions, even if those conversions would’ve happened anyway. In those cases, the platform claims success, but your bottom line tells a different story.

Strategic application:

• Healthy frequency numbers vary by category, brand, and objective. Consider how your business KPIs move when frequency is increased or decreased.
• Second-guess results when you see high frequency mixed with a limited audience size (like a retargeting audience).
• Frequency is typically reported by platform. Consider the impact of other messaging across the entire media mix.

4. Search Volume Maximization: Search Imp Share Lost (Budget)

Search is a low-funnel tactic – your customer is raising their hand and actively looking for something. That’s why well-optimized search campaigns often deliver some of the strongest performance. However, in most cases, you can’t force more searches to happen, so eventually, volume plateaus.

Google Keyword Planner or third-party tools like SEMRush can help identify estimated search volume, but the metric in the account to look for is Search Imp Share Lost (Budget). This number tells you what percentage of searches you missed due to budget limitations. It’s a great metric to identify how much room you can potentially scale with the keywords and targeting that you are utilizing today.

When that number drops below 5–10%, that tells you that you are capturing the bulk of the volume. So you either need to focus on increasing Rank (to help show on more searches) or look to add other keywords / match types / targeting to expand the pool of potential searches and continue to scale.

Strategic application:

• Use Search Imp Share Lost (Budget) to identify when volume for highly targeted campaigns / geographies are beginning to saturate.
• Avoid chasing the last few % lost due to budget – it’s often exponentially more expensive.
• This metric can also be an important strategic trigger to expand targeting and/or look at factors that influence Rank to improve visibility as you continue to scale.

5. Brand Development: Measuring Brand Marketing ROI

Not all marketing initiatives directly drive sales. Brand marketing builds long-term equity that may not show immediate revenue impact but creates a sustainable competitive advantage. The challenge? Quantifying these efforts to justify the budget.

Unlike performance marketing metrics (which measure direct response), brand metrics track awareness, perception, and engagement—critical factors that influence purchase decisions over time.

Key brand metrics worth tracking:

• Brand Awareness: Percentage of your target audience that recognizes your brand (measured through surveys)
• Share of Voice: Your brand's visibility in the market compared to competitors (measured through media monitoring tools)
• Brand Sentiment: How positively your audience perceives your brand (tracked through social listening and sentiment analysis)
• Direct Search Volume: People searching specifically for your brand name (a powerful indicator of brand strength)

Strategic application:

• Allocate a dedicated portion of your budget to brand-building activities—typically 30–60% depending on category, maturity, and competition.
• Measure brand metrics quarterly to track progress against benchmarks.
• Recognize that brand marketing requires consistent investment over time, unlike campaign-based performance marketing.
• Understand that strong brands typically command higher margins and customer loyalty, directly impacting both revenue and CAC efficiency.

Measuring True Impact: Incrementality Testing

One significant challenge with traditional marketing metrics is determining causality. Just because a customer clicked your ad before purchasing doesn’t mean it caused the sale; they might have converted anyway.

Incrementality testing helps to solve this problem by measuring the true lift your marketing activities generate. Rather than focusing on direct attribution (this customer saw an ad, then purchased), incrementality helps identify the amount of additional revenue, leads, etc. that were directly driven by the advertising spend.

How incrementality testing works:

• Create a randomized test group and control group
• Expose only the test group to your marketing activity
• Measure the difference in conversion rates between groups
• Calculate the incremental lift attributable to your marketing

Strategic application:

• Use incrementality testing to quantify ‘true’ ROAS across tactics and channels.
• Better project bottom line business impacts from incremental ad spend.
• Challenge assumptions about high-performing channels or tactics, like retargeting or branded search, that may actually be claiming credit for sales that would have happened anyway.
• Remember, incrementality tests reflect results for a specific audience and timeframe, so run them consistently to maintain a reliable understanding of performance.

Choosing the Right Metrics for Your Business

The best metrics for your business depend on your growth stage, industry, and business model. Every business has different needs, and often those needs change over time. By keeping your most important KPIs front and center for all your advertising-related activities, you can better optimize your campaigns to the changing business landscape.

Remember, the goal isn't to optimize for metrics themselves but to use them as guides for making smart marketing investments that drive business growth.
