Plain-English definitions of every term we use — no jargon, no padding. 26 terms defined.

A

AI Agent

Unlike chatbots, AI agents have persistent memory, tool access (email, CRM, calendar), and the ability to execute multi-step tasks independently.

AI Chatbot

A conversational AI deployed on websites, messaging platforms, or SMS that can engage with users, answer questions, qualify leads, and take actions (like booking appointments). Modern AI chatbots use large language models and are trained on specific business context — far beyond simple FAQ bots.

CAC (Customer Acquisition Cost)

The total cost of acquiring one new customer, calculated by dividing total marketing and sales spend by the number of new customers acquired in a given period. CAC is one of the most important metrics in any business — if it exceeds customer lifetime value, the business model is broken.

Conversion Rate

The percentage of visitors or leads who take a desired action — purchasing, booking a call, signing up, etc. Website conversion rates typically range from 1–5%. AI chatbots, optimized landing pages, and faster lead response time all directly improve conversion rate.

CPM (Cost Per Mille)

The cost of 1,000 ad impressions. CPM is the standard pricing model for display and social media advertising. Rising CPMs (which have increased 40%+ since 2022) mean the same budget reaches fewer people — making creative quality and audience precision more important than ever.

CPA (Cost Per Acquisition)

The cost of acquiring one conversion — a lead, a booked call, a purchase, or a signed contract. CPA is more actionable than CPM or CPC because it connects ad spend directly to business outcomes.

LTV (Lifetime Value)

The total revenue a business can expect from a single customer over the entire relationship. LTV must exceed CAC for a business to be profitable. Increasing LTV through retention automation, upsell sequences, and referral programs is often more profitable than acquiring new customers.

R

ROAS (Return on Ad Spend)
