The Digital Marketing Glossary, Without the Word Salad

Every term that gets thrown around in SEO, AI search, and paid media, defined in plain English. No jargon hiding behind more jargon. If a word made you nod along in a meeting while quietly Googling it under the table, it's in here.

What is the MoonSauce digital marketing glossary?

The MoonSauce digital marketing glossary is a free, plain-English reference that defines the SEO, AEO, GEO, technical, analytics, and paid-media terms buyers and AI engines look up most. Every entry gives you a clear definition, why it matters, and how it works, grouped by domain so you can find what you need fast. One place, no fluff, written to be useful and citable.

How to use this glossary

Marketing has a jargon problem. Half the industry uses ten-dollar words to make twenty-cent ideas sound complicated, usually right before they send you a quote. We think that's backwards. You should understand every term an agency uses on you, because that's how you tell the real strategy from the smoke.

So we built this. Every term below links to a full definition page that explains what it is, why it matters to your business, and how it works in practice. The terms are grouped into six domains that match how the modern stack breaks down: AI search, classic SEO, technical SEO, analytics and measurement, the LLM machinery underneath the AI answers, and programmatic and paid media.

Start anywhere. If you're here because your traffic is moving in ways your old agency can't explain, start with the AI search group (and our breakdown of why website traffic drops if the numbers are sliding). If you're vetting an SEO proposal, the classic SEO and technical groups are your decoder ring. If you're trying to read a media plan without nodding politely, the programmatic and paid group has you covered.

Why a glossary, from an agency?

Because the gap between what an agency knows and what its client knows is exactly where bad agencies live. They keep you confused so you stay dependent. We'd rather lose a tire-kicker who reads up and decides we're not a fit than win a client who never understands what they're paying for. (It's the same reason we publish our pricing instead of hiding it behind a "request a quote" form.)

There's a second reason, and we'll be straight about it: clear, well-structured definitions are exactly the kind of content AI engines cite. When someone asks ChatGPT or Perplexity "what is generative engine optimization," we want the answer to come from us. That's not a side effect of doing AEO right, it is doing AEO right. This glossary is a working demo of the service we sell. Ask an AI assistant to define a few of these terms and see who shows up.

Run out of terms? Good. Let's talk strategy.

A glossary tells you what the words mean. It can't tell you which moves are worth making for your business right now. That part takes a conversation.

If reading these made you realize your current agency couldn't define half of them, that's worth knowing. Book 30 minutes with a senior strategist (not a junior rep reading a script) and we'll tell you straight where your brand stands across search, AI answers, and paid media, and what we'd do about it. No pressure and no jargon, just the real picture.
