Key Performance Indicators: Marketing Metrics that Matter

When people say "it depends" in response to what metrics are important in a marketing campaign, it's often a way of avoiding specifics. In reality, there are two key categories of metrics that are crucial in any marketing effort, regardless of the campaign specifics:

1. Platform Metrics: These metrics reflect the performance of your campaign on the specific platform where you're running the ads. They provide insight into how well the ad is engaging the audience, how effectively it's being delivered, and whether the platform is helping you reach your objectives

2. Internal Metrics: These metrics show the campaign’s direct impact on your business performance. They relate directly to your business outcomes, such as revenue or customer acquisition or whatever the campaign objectives are. You might be getting the clicks on your Facebook ads, but are they translating to sales?

For each of these categories, you measure the absolute performance (eg. clicks, impressions etc.) as well as the efficiency (eg. Conversion Rate - CVR, Click-through Rate - CTR etc, Return-on-investment ROI. )

Platform Metrics

Platform metrics depend on the Platform (e.g. Facebook, Google, Microsoft Bing, X, etc.) and the Channel (PPC, Email, Social, Influencer, etc.). Below is a general overview of key metrics for some of the more common channels.

Key Metrics:

• Click-Through Rate (CTR): Percentage of users who click on your ad after seeing it. Indicates how effective your ad is at capturing attention.

• Cost-Per-Click (CPC): The amount paid for each click on your ad. Lower CPC means more cost-efficient campaigns.

• Conversion Rate: Percentage of users who clicked on your ad and completed a desired action, such as making a purchase or signing up.

• Quality Score (Google Ads-specific): Google’s rating of the relevance and quality of your ad, keywords, and landing page. Higher quality scores can lead to lower costs and better ad positions.

• Impressions: Number of times your ad is shown, whether or not it is clicked.

• Cost-Per-Acquisition (CPA): How much it costs to acquire a customer through the campaign. It is calculated by dividing the total ad spend by the number of conversions.

2. Social Media Marketing

Platforms: Facebook, Instagram, LinkedIn, Twitter (X), TikTok, etc.

  Email CTR = (Clicks / Emails Delivered) × 100

• Bounce Rate: Percentage of emails that couldn’t be delivered. High bounce rates indicate issues with your email list or sender reputation.

Internal Metrics

Internal Metrics are the key performance indicators (KPIs) that reflect the impact of a marketing campaign on your business's bottom line.

• Lead Quality: Not all leads are created equal. You need to monitor the quality of leads coming from the campaign. Are they converting into paying customers or wasting your sales team's time?

• Sales Growth: This measures whether your marketing campaigns are translating into an actual increase in sales over time.
