I have a computer science degree. I spent 15 years on Wall Street building trading systems and risk platforms at Merrill Lynch, Barclays, and MUFG. I managed teams, architected software, shipped products used by thousands of traders. I was good at my job.
And I had absolutely no idea what an MQL was.
When I started Tuple Tech — my managed IT and cloud services company — I figured the hard part would be the technology. It wasn't. The hard part was everything I'd never had to think about before: sales, marketing, positioning, lead generation. I walked into my first conversation with a marketing consultant and she started rattling off terms like ICP, funnel, CAC, and nurture sequence. I nodded along like I understood.
I didn't understand any of it.
Here's what I've learned since: I'm not the only one. Most small business owners — doctors, solopreneurs, architects, lawyers — are experts in their craft. They built something real. But nobody taught them the language of marketing. And when you don't speak the language, you can't ask the right questions, you can't evaluate whether your money is being well spent, and you definitely can't tell if something is working or not.
So this is the guide I wish someone had handed me on day one. No fluff, no jargon-to-explain-jargon. Just the terms that actually matter, explained the way I'd explain them to a friend over coffee. If you're a founder or business owner who's about to invest in marketing for the first time — or you already are and you're not sure what half the reports mean — this is for you.
Here is what you will walk away with: plain-English definitions of 19 marketing terms organized around the customer journey — from SEO and CTR to MQL, CAC, and LTV. Each one includes a real-world analogy, why it matters to your bottom line, and a benchmark so you know what good looks like. Bookmark this page. You will come back to it.
How People Find You — The Awareness Terms
Before anyone buys from you, they have to find you. These five terms describe how strangers discover your business online.
SEO (Search Engine Optimization) is the practice of making your website show up when people search Google. Think of it like having a good sign on a busy street — it helps people find your shop without you paying for every visitor. An Ahrefs study found that the average page ranking on page one of Google is over 2 years old. SEO is a long game, but once it works, it keeps working for free.
Organic vs Paid is the simplest distinction in marketing. Organic means people find you naturally — through Google searches, social media content, word of mouth. Paid means you bought an ad. Both matter. Organic compounds over time; paid is instant but stops the moment you stop spending. The best businesses have both running.
Impressions are how many times your content was shown to someone. Not clicks, not reads — just eyeballs. If your social post appeared in 500 people's feeds, that's 500 impressions. It's the very top of the funnel. High impressions with low engagement usually means your message isn't landing.
CTR (Click-Through Rate) measures what percentage of people who saw your content actually clicked on it. The formula is simple: clicks divided by impressions. If 1,000 people saw your Google ad and 30 clicked, your CTR is 3%. According to WordStream, the average CTR across industries is about 3.17% for search ads. Anything above that and you're doing well. Below it, your headline or targeting probably needs work.
CTA (Call to Action) is the thing you want someone to do. "Book a free consultation." "Join the waitlist." "Call now." Every piece of marketing needs one. If someone reads your entire email or visits your website and there's no clear next step, you just wasted that attention. One CTA per page. Make it obvious.
When a Stranger Becomes Interested — The Lead Terms
Someone found you. Now what? These terms describe the moment a stranger raises their hand and says "I might be interested."
Lead Generation (Lead Gen) is the process of getting strangers to express interest in your business. A form fill on your website, a phone call, an email signup, someone DMing you on Instagram — all of those are lead generation. The goal isn't volume. It's getting the right people to raise their hand. This is one of the core things theKrew's AI agents handle — running the outreach, content, and follow-ups that generate leads without you doing it manually.
ICP (Ideal Customer Profile) is a description of the perfect customer for your business. Not "everyone." The specific type of person who gets the most value from what you sell and is most likely to buy. A plumber's ICP might be homeowners within 20 miles who own houses built before 1990. An architect's ICP might be commercial developers in the tri-state area with projects over $2M. When you know your ICP, every dollar of marketing goes further because you're not wasting it on people who were never going to buy.
Landing Page is a single web page designed to do one thing: get a visitor to take action. It's not your homepage. It's a focused page with one CTA, one message, and zero distractions. If you're running ads, they should point to a landing page, not your homepage. The difference in conversion rates is enormous.
Conversion Rate is the percentage of people who take the action you want. 100 visitors land on your page, 3 fill out the form — that's a 3% conversion rate. HubSpot's benchmark data shows that the average landing page conversion rate across industries is about 5.89%. If yours is below 2%, something's off — the message, the audience, or the offer.
Funnel is the path from stranger to customer. It's wide at the top (many people see you) and narrow at the bottom (fewer buy). It's not a literal funnel — it's a mental model for understanding where people drop off. If 1,000 people visit your site, 100 become leads, 20 get a proposal, and 5 buy — that's your funnel. Knowing these numbers tells you exactly where to focus.
Separating Browsers from Buyers — The Qualification Terms
Not every lead is ready to buy. These terms describe how you figure out who's serious, keep the conversation going, and track where everyone stands.
MQL (Marketing Qualified Lead) is a lead that's shown enough interest that marketing says "this one's worth talking to." Maybe they visited your pricing page three times. Opened your last four emails. Downloaded your guide. They haven't asked for a call yet, but their behavior says they're thinking about it. Recognizing MQLs is critical — these are the signals that tell you marketing is working before the revenue shows up.
SQL (Sales Qualified Lead) is an MQL that's been vetted further and is ready for a real sales conversation. They have budget, they have need, and the timing is right. The handoff from MQL to SQL is where marketing ends and sales begins. In a small business, that might just mean you personally calling them instead of sending another email.
CRM (Customer Relationship Management) is software that tracks every interaction with leads and customers. Think of it as a shared memory for your business. Who contacted you, when, what they asked, where they are in the process. Salesforce and HubSpot are the big names, but even a well-maintained spreadsheet counts. The point is: if a lead calls and you have to ask "remind me who you are," you need a CRM.
Nurture means staying in touch with leads who aren't ready to buy yet. Email sequences, helpful content, check-ins, occasional offers. The slow build that turns "maybe later" into "let's go." Marketing takes time — and nurture is the engine that keeps working during that time. Most small businesses skip this entirely, which is why their pipeline goes dry between bursts of activity.
Pipeline is all the potential deals you're tracking right now, at various stages. A healthy pipeline has leads at every stage — some just discovered you, some are in conversations, some are close to signing. An empty pipeline means you'll be scrambling in 90 days. That's the real cost of not marketing — not the money you spend, but the revenue gap when the pipeline runs dry.
theKrew handles lead gen, nurture, and pipeline management automatically — so you can focus on the terms that matter, not the tasks behind them.

These are the terms your accountant brain will love. They tell you whether your marketing is actually making money or just making noise.
CAC (Customer Acquisition Cost) is how much it costs to get one new customer. Total marketing spend divided by number of new customers acquired. If you spent $1,200 on marketing last quarter and got 10 new customers, your CAC is $120. If your average customer pays you $500, that math works. If they pay you $80, it doesn't. CAC is the single most important number in marketing. Compare it to what a customer is actually worth — which brings us to LTV.
LTV (Lifetime Value) is how much a customer is worth over the entire relationship, not just the first purchase. A dental patient who comes in twice a year for 10 years is worth far more than their first cleaning. Bain & Company research found that increasing customer retention by just 5% increases profits by 25–95%. The goal: your LTV should be at least 3x your CAC. If it's not, you're either spending too much to acquire customers or not retaining them long enough.
ROI (Return on Investment) is the simplest question in business: did you get more out than you put in? The formula: (revenue from marketing minus cost of marketing) divided by cost of marketing. If you spent $1,188/year on marketing and it generated $120,000 in revenue, the ROI is so obvious you don't need a calculator. The hard part is attribution — knowing which revenue came from which marketing effort. That's where analytics and tracking matter.
Churn is the percentage of customers who leave in a given period. If you started the month with 100 customers and lost 5, your monthly churn rate is 5%. Low churn means your business is sticky — people stay because they're getting value. High churn means you have a leaky bucket. And here's the uncomfortable truth: no amount of marketing fixes a churn problem. If customers keep leaving, fix the product or service first, then market.
You Don't Need to Master These. You Just Need to Recognize Them.
When I started my entrepreneurial journey after 15 years in tech, I didn't need to become a marketing expert. I needed to know enough to ask the right questions. To look at a report and understand whether the numbers were good or bad. To sit in a meeting and not nod along blindly when someone mentioned CAC or pipeline or nurture sequences.
That's what this glossary is for. Not to turn you into a marketer. To turn you into an informed business owner who makes confident decisions about where their money goes.
And here's the thing — you don't have to do most of this yourself. The SEO, the lead gen, the nurture sequences, the analytics — theKrew's 7 AI agents handle the execution. Aria runs your campaigns, tracks your pipeline, sends the emails, publishes the content. Your job is to understand what's happening and steer the ship. That's a lot easier when you speak the language.
If your marketing keeps stopping when things get busy, or you've been putting it off because it feels overwhelming, now you have the vocabulary. The next step is easier than you think. It starts at $99/month.
