Click-to-Open Rate (CTOR)

Click-to-open rate (CTOR) is an email marketing metric that measures the percentage of people who clicked a link inside an email, out of only those who actually opened it. Not everyone who received it. Not everyone on your list. Just the ones who opened it and then decided — or didn’t — to act on … Continue reading "Click-to-Open Rate ...

Cost Per Day (CPD)

Cost per day (CPD) is a flat-rate advertising pricing model where an advertiser pays a fixed fee to have their ad displayed for a set number of days — regardless of how many times it’s seen or clicked. The clock runs. The fee stays the same. That’s the whole model. CPD is a time-based pricing … Continue reading "Cost Per Day ...

Email Heat Map

An email heat map is a visual tool that shows exactly how recipients interact with your email — where they click, how far they scroll, and which parts of the layout they ignore entirely. Instead of staring at a spreadsheet of click data, you see it rendered as a colour-coded overlay on top of the … Continue reading "Email Heat ...

Average Customer Lifespan

Average Customer Lifespan (ACL) is the typical amount of time a customer continues to buy from your business before they stop for good. It’s the metric that tells you if you’re building a loyal community or if you’re essentially a “one-night stand” brand. While metrics like conversion rates focus on the start of the relationship, … Continue reading "Average Customer ...

Cost Per Acquisition

Cost Per Acquisition (CPA) is essentially the price tag on a specific “win” – whether that’s a sale, a lead, or a new signup. It is the metric that tells you if your marketing is actually efficient or if you are just paying for digital noise. While other stats might track how many people saw … Continue reading "Cost Per ...

Subscriber Rate

Subscriber rate is the metric that tells you if your website is a revolving door for window shoppers or a tool for building a loyal audience. It measures the percentage of visitors who decide to stop just browsing and actually join your inner circle—whether that’s through an email list, an SMS club, or a premium … Continue reading "Subscriber ...

Scroll Depth

Ever wonder if people are actually reading your content or just glancing at the headline and hitting the “back” button? That’s exactly what scroll depth measures. It’s the percentage of a webpage that a visitor actually views before they decide they’ve seen enough. While a page view tells you someone landed on your site, scroll … Continue reading "Scroll ...

Unsubscribe Rate

Unsubscribe Rate is the percentage of people who choose to opt out of your mailing list after receiving an email. It’s the ultimate “rejection” metric in marketing. While an open rate tells you if people are curious, and a click rate tells you if they are interested, the unsubscribe rate tells you if you’ve actually … Continue reading "Unsubscribe ...

Purchase Frequency

Purchase Frequency is a metric that tells you how often the average customer buys from your business over a specific period. It’s essentially a measure of “habit.” In marketing terms, this isn’t about how much money they spend each time, but rather how many times they choose to come back. It’s the difference between a … Continue reading "Purchase ...
