Marketing success isn’t just about launching campaigns—it’s about tracking performance, understanding audience behaviour, and refining strategies for better results. Whether you’re running email marketing, social ads, or content campaigns, measuring the right key performance indicators (KPIs) is crucial.

Here are 10 essential marketing metrics that will help you assess campaign performance, identify areas for improvement, and drive data-backed decision-making.
1. Click-Through Rate (CTR) – Are People Engaging with Your Content?
CTR measures how many people clicked on a link within your campaign, whether in an email, social ad, or landing page. A high CTR indicates strong engagement, while a low one may suggest weak messaging or poor targeting.
Formula: 📊 (Total Clicks / Total Impressions) x 100
How to Improve It:
✔ Use personalisation to create more relevant content
✔ A/B test different CTAs (Call to Actions)
✔ Optimise subject lines and ad copy
2. Conversion Rate – Are Clicks Turning into Actions?
CTR tells you if people are interested, but conversion rate tells you if they actually take action—whether that’s signing up, making a purchase, or downloading content.
Formula:📊 (Conversions / Total Visitors) x 100
How to Improve It:
✔ Ensure your landing page matches ad intent
✔ Remove friction from the signup or purchase process
✔ Use a retargeting tool to re-engage non-converters
3. Customer Acquisition Cost (CAC) – How Much Are You Spending per New Customer?
CAC helps you understand how much you’re spending to acquire each new customer. This is critical in determining if your marketing efforts are cost-effective.
Formula:📊 (Total Marketing Costs / Number of New Customers)
How to Improve It:
✔ Focus on high-performing channels
✔ Use a campaign tracking tool to optimise underperforming campaigns
✔ Improve your customer journey to increase conversions
4. Return on Ad Spend (ROAS) – Are Your Ads Profitable?
ROAS measures how much revenue you’re generating for every £1 (or $1) spent on advertising.
Formula:📊 (Revenue from Ads / Ad Spend)
How to Improve It:
✔ Target high-intent audiences with a retargeting and segmentation strategy
✔ Use advanced customer insights to refine your messaging
✔ A/B test creatives, ad formats, and targeting
5. Email Open Rate – Are People Reading Your Emails?
If you’re running an email marketing campaign, your open rate is a strong indicator of how well your subject lines and sender reputation are performing.
Formula:📊 (Emails Opened / Emails Sent) x 100
How to Improve It:
✔ Write compelling, curiosity-driven subject lines
✔ Personalise email content based on customer tracking tool data
✔ Avoid spam triggers and test different send times
6. Bounce Rate – Are Visitors Leaving Too Soon?
Bounce rate measures how many people leave your website or landing page without taking action. A high bounce rate could mean your page isn’t relevant, loads too slowly, or isn’t engaging enough.
Formula:📊 (Single-Page Visits / Total Visits) x 100
How to Improve It:
✔ Make your landing pages mobile-friendly
✔ Optimise page load speed
✔ Ensure the content matches the intent of the campaign
7. Engagement Rate – Are People Interacting with Your Content?
This metric is crucial for social media campaigns, as it tracks likes, shares, comments, and interactions.
Formula:📊 (Total Engagements / Total Followers or Impressions) x 100
How to Improve It:
✔ Post interactive content like polls, quizzes, and videos
✔ Leverage user-generated content to boost engagement
✔ Use social listening tools to track audience sentiment
8. Cost per Lead (CPL) – How Efficient is Your Lead Generation?
CPL tells you how much it costs to generate a single lead through your marketing efforts.
Formula:📊 (Total Spend / Total Leads Generated)
How to Improve It:
✔ Use retargeting and segmentation to refine lead quality
✔ Optimise ad creatives and targeting
✔ Improve your landing pages for better lead conversion
9. Customer Lifetime Value (CLV) – Are Your Customers Staying with You?
CLV estimates how much revenue a single customer will generate over their entire relationship with your business.
Formula:📊 (Average Purchase Value x Purchase Frequency x Customer Lifespan)
How to Improve It:
✔ Focus on customer retention and loyalty programs
✔ Offer personalised recommendations based on past behaviour
✔ Improve onboarding to increase product stickiness
10. Attribution Metrics – Where Are Your Best Customers Coming From?
Attribution helps you understand which marketing channels contribute most to conversions. Whether you’re using first-touch, last-touch, or multi-touch attribution, this data is essential for budget allocation.
How to Improve It:
✔ Use a campaign analytics software to track attribution
✔ Implement UTM tracking for better cross-channel insights
✔ Compare assisted conversions vs. direct conversions
