Cross-Sell Rate

Cross-sell rate is the percentage of customers who purchase an additional, complementary product alongside — or following — their original purchase. It’s the metric that tells you how well a business is turning a single transaction into a broader one. The cross-sell rate is the percentage of customers who purchase additional products or services that … Continue reading "Cross-Sell ...

Lead-to-Customer Conversion Rate

The lead-to-customer conversion rate is the percentage of leads that ultimately become paying customers. It sits at the intersection of marketing and sales — capturing the full journey from initial interest to closed deal — and is one of the most direct measures of how well that journey actually works. The lead-to-customer conversion rate is … Continue reading "Lead-to-Customer Conversion ...

Email Response Rate

Email response rate is the percentage of sent emails that receive a reply. It’s a direct measure of how many people actually wrote back — not just opened, not just clicked, but responded. And that distinction matters more than it might seem. Email response rate refers to the percentage of people who reply to your … Continue reading "Email Response ...

Product-Qualified Lead

A product-qualified lead (PQL) is a user who has tried a product — usually through a free trial or freemium plan — and demonstrated through their actual behaviour that they’re likely to become a paying customer. Not because they downloaded a whitepaper. Not because they match a demographic profile. Because they used the product and … Continue reading "Product-Qualified ...

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.

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 ...
