What is Digitial Marketing ROI

ROI stands for Return on investment.

It is essential for assessing the effectiveness of your campaigns and optimizing your marketing strategy.

Formula of ROI = (Net profit/cost of investment) x 100

Where: Net profit refers to the earnings or gains generated from the investment.

To measure digital marketing ROI effectively, you should focus on key metrics and utilize appropriate tools.

Key Metrics For ROI

1. Conversion Rate

First, calculate the percentage of visitors who take a desired action on your website, such as making a purchase, clicking on a specific link, signing up for a newsletter, or filling out a contact form.

Formula for conversion rate = (Number of conversions/Total number of visitors) x 100

For example, if a website had 1000 visitors in a month and 250 of them made a purchase, the conversion rate would be:

(250 / 1000) x 100 = 25%

2. Customer Acquisition Cost (CAC)

It is a metric used by companies and marketers to figure out how much it costs to bring in a new client. Calculating the CAC is important for understanding the efficiency and effectiveness of a company's marketing and sales efforts.

Formula of CAC = Total Sales and Marketing Costs / Number of New Customers Acquired

3. Customer Lifetime Value (CLV)

Customer lifetime Value is a critical metric for assessing the long-term value and profitability of a customer. This helps you assess the return on investment over the customer's entire lifecycle.

Formula for CLV = (Average Purchase Value X Average Purchase Frequency) x Customer Lifespan

  • Average Purchase Value: This represents the average amount a customer spends in a single purchase.

  • Average Purchase Frequency: This is the average number of times a customer makes a purchase within a specific time frame, typically a year.

  • Customer Lifespan: This refers to the average length of time a customer continues to do business with the company.

4. Return on Ad Spend (ROAS)

It is a key metric used in digital advertising and marketing to evaluate the effectiveness and profitability of advertising campaigns, particularly in online advertising platforms like Google Ads and Facebook Ads.

Formula for ROAS = Revenue Generated from Advertising/Cost of Advertising

5. Click-Through Rate (CTR)

It is a metric used in online advertising and email marketing to measure the effectiveness of an advertisement, link, or call-to-action in generating clicks and directing users to a specific web page or destination.

Formula of CTR = (Number of Clicks / Number of Impressions) x 100

6. Cost per click (CPC) and cost per acquisition (CPA)

CPC and CPA are two important metrics in online advertising, and they represent different ways to measure and evaluate the cost and effectiveness of advertising campaigns:


It's the cost incurred by an advertiser each time a user clicks on their ad. In other words, it represents the amount of money paid for each click generated by an advertisement.

Formula = Total Cost of Campaign / Total Number of Clicks

CPC is commonly used in pay-per-click (PPC) advertising models, such as Google Ads


It measures the cost incurred by an advertiser to acquire a customer or lead who takes a specific action, such as making a purchase, filling out a form, or signing up for a newsletter.

Formula = Total Cost of Campaign / Total Number of Acquisitions (Actions)

7. Traffic Sources

Analyze the sources of your website traffic (e.g., organic search, social media, email, paid ads) to determine which channels are most effective.

8. Bounce Rate

Assess the percentage of visitors who leave your website after viewing only one page. High bounce rates may indicate issues with landing pages or content.

Formula of Bounce Rate = (Number of Single-Page Visits/Total Number of Visits) x 100

9. Social Media Engagement

Evaluate likes, shares, comments, and other engagement metrics on social media platforms to gauge the effectiveness of your social media marketing.

10. Email Marketing Metrics

Measure metrics like open rates, click-through rates, and conversion rates to evaluate the performance of your email marketing campaigns.
