Using Data in Digital Marketing

Finding the metrics that matter, a tale of two campaigns

James stared at his computer screen, a mix of confusion and frustration etched across his face. His latest digital marketing campaign had generated thousands of likes and shares, yet sales remained flat. Across town, his competitor Lisa was celebrating another successful quarter, despite having a seemingly quieter social media presence. The difference? Lisa understood the story behind the numbers.

“Vanity metrics are like sugar rushes,” Lisa would often say at industry conferences. “They feel great at first, but they don’t sustain your business. The real power lies in understanding which numbers truly matter.”

What the experts say:

Using vanity metrics to measure the performance of content campaigns on social media is perhaps one of the simplest things to do in marketing but also one of the most difficult.

It’s simple because vanity metrics are easy to obtain in large numbers – all platforms supply them; it’s difficult because they are often ambiguous when it comes to reporting a return on investment (ROI) or value to a business.

The evolution of marketing measurement

In the early days of digital marketing, success was measured simply, more hits meant more success. Website counters proudly displayed visitor numbers, and early social media managers celebrated every new follower like a personal victory. But as digital marketing matured, so did our understanding of measurement.

Today’s digital landscape offers an ocean of data, but not all metrics carry equal weight. The key isn’t just collecting numbers, it’s understanding which numbers tell the meaningful stories about your business.

The metrics that matter

Imagine your digital marketing strategy as a journey. Different metrics serve as signposts along the way, each telling you something unique about your progress. Let’s explore these signposts:

Traffic Metrics (the foundation)

Think of website traffic as the footfall in a physical store. But unlike a physical store, digital analytics can tell you:

• Where visitors came from (acquisition channels)
• How long they stayed (session duration)
• What they looked at (page views)
• Whether they’ve been here before (new vs. returning visitors)

These metrics form the foundation of your digital understanding, like a doctor checking your vital signs. They don’t tell the whole story, but they indicate overall health.

What the experts say:

Among surveyed consumers in 2024, Google and other search engines were the most popular channels for product discovery, and for researching more information on products or comparing items.

Engagement metrics (the relationship builders)

If traffic metrics are about getting people through the door, engagement metrics tell you what they do once they’re inside:

• Bounce rate (did they leave immediately?)
• Pages per session (how deeply did they explore?)
• Average time on page (were they actually reading?)
• Social shares and comments (did they find it valuable enough to share?)

Conversion metrics (the bottom line)

This is where potential turns into reality:

• Conversion rate (what percentage of visitors take desired actions?)
• Cost per conversion (how much are you spending to get each result?)
• Shopping cart abandonment rate (where are you losing potential customers?)
• Lead-to-customer rate (how many prospects become paying customers?)

What the experts say:

Conversion rates are calculated by simply taking the number of conversions and dividing that by the number of total ad interactions that can be tracked to a conversion during the same time period. For example, if you had 50 conversions from 1,000 interactions, your conversion rate would be 5%, since 50 ÷ 1,000 = 5%.

ROI metrics (the business impact)

The ultimate measure of success:

• Customer Lifetime Value (CLV)
• Return on Ad Spend (ROAS)
• Cost per Acquisition (CPA)
• Marketing Qualified Leads (MQLs)

The art of choosing the right metrics

Back to our tale of James and Lisa. James’s campaign looked successful on the surface, high engagement rates, viral content, thousands of likes. But Lisa had focused on metrics aligned with her business goals:

• For brand awareness: Reach and impression share
• For customer engagement: Comment sentiment and share of voice
• For sales: Conversion rate and customer acquisition cost
• For customer loyalty: Repeat purchase rate and customer lifetime value

Real world examples

E-commerce revolution

When Maria launched her sustainable fashion brand, she initially tracked everything. “I was drowning in data,” she recalls. “Then I realised I needed to focus on metrics that matched my business stage.”

In the first six months, she concentrated on:

• New visitor to email subscriber conversion rate
• Email engagement rates
• First-time purchase conversion rate

As her business grew, she evolved to tracking:

• Customer retention rates
• Average order value
• Customer lifetime value

The result? A 300% growth in revenue year-over-year, with marketing costs increasing by only 50%.

B2B transformation

Tech startup Quantum Solutions shifted their metric focus from lead quantity to lead quality. By tracking:

• Time to qualification
• Sales qualified lead (SQL) conversion rate
• Deal closure time

They reduced their sales cycle by 40% while increasing their average deal size by 75%.

The future of marketing metrics

As we look ahead, new metrics are emerging:

• Customer engagement score (combining multiple engagement indicators)
• Brand sentiment analysis (using AI to analyze customer feedback)
• Cross-channel attribution (understanding the complete customer journey)
• Sustainability impact metrics (measuring environmental footprint of digital campaigns)

The human element

Remember, behind every metric is a human story. The bounce rate isn’t just a percentage, it represents real people making decisions about your content. The conversion rate isn’t just a number, it’s individuals choosing to trust your brand.

Choosing your path

As you navigate the world of digital marketing metrics:

1. Start with your business goals
2. Choose metrics that directly align with these goals
3. Focus on trends rather than absolute numbers
4. Remember that context is everything
5. Don’t let perfect be the enemy of good

In the end, James learned from Lisa’s approach. He shifted his focus from vanity metrics to meaningful measurements, and within six months, his business had transformed. “The numbers were always there,” he reflected. “I just needed to learn which ones told the real story.”

Your metrics should tell a story, not just any story, but your story. Choose them wisely, track them diligently, and let them guide you toward digital marketing success.

The right metrics aren’t just numbers on a dashboard, they’re the pulse of your digital marketing strategy, telling you when to push forward, when to pivot, and when to celebrate your success.
