Digital marketing and automation glossary
Every term an agency might use on you, defined in a sentence, with a second sentence explaining why it should matter to your business. Search it, filter it, or read the lot.
40 terms, defined plainly
Each entry says what the term means and why it should matter to you. If a proposal uses one of these words without being able to explain the second part, ask harder questions.
- Above the fold
- What a visitor sees before scrolling, which differs sharply between a phone and a desktop.Why it matters: If what you sell and how to ask for it are not visible immediately, most mobile visitors never find them.
- Accessibility (WCAG)
- Standards that keep a site usable with a keyboard, a screen reader, or low vision.Why it matters: It widens your audience and reduces legal exposure, and the same fixes usually improve everyone's experience.Related work
- AI agent
- A language model given tools, instructions and boundaries so it can complete a task rather than only produce text.Why it matters: Useful for triage, answering repeat questions and drafting — risky without explicit limits on what it may do.Related work
- API
- A defined interface a system exposes so other software can read or write its data programmatically.Why it matters: Whether a tool has a usable API decides whether automating around it is a small job or a rebuild.
- Attribution
- Assigning credit for a sale to the channels and touches that contributed to it.Why it matters: Without it you cut the channel that assists every sale because it never gets the last click.Related work
- Bounce rate
- The share of visits where someone leaves without a second meaningful interaction.Why it matters: High bounce on a service page usually means a mismatch between the search and the page, not a design problem.
- CAC (customer acquisition cost)
- Total sales and marketing cost divided by the number of new customers won.Why it matters: Compared against customer lifetime value, it tells you whether growth is profitable or merely busy.
- Canonical URL
- The single address you declare as the official version of a page when the same content is reachable at more than one URL.Why it matters: Without one, duplicate versions compete with each other and split the credibility you have earned.
- CMS (content management system)
- The interface that lets non-developers edit page content without touching code.Why it matters: Without one, every text change becomes a support ticket and your site slowly goes stale.
- Conversion rate
- The share of visitors who take the action the page exists for — usually a call, a form or a booking.Why it matters: Doubling conversion rate is almost always cheaper than doubling traffic.
- Core Web Vitals
- Google's measurements of loading speed, interaction responsiveness and visual stability on a real device.Why it matters: Slow, jumpy pages lose visitors before they ever see your offer, and Google measures that.Related work
- CPC (cost per click)
- What you pay each time someone clicks an ad.Why it matters: A low CPC on the wrong keyword is more expensive than a high CPC on a keyword that buys.Related work
- CPL (cost per lead)
- Total spend divided by the number of qualified inquiries it produced.Why it matters: It is the first honest number for comparing channels, as long as 'qualified' means the same thing across them.
- CRM
- The shared system of record for leads, customers and every interaction with them.Why it matters: If your pipeline lives in one person's inbox, the business cannot see or recover what they drop.
- E-E-A-T
- Google's shorthand for experience, expertise, authoritativeness and trustworthiness — the signals a page gives that a real, qualified business stands behind it.Why it matters: Named people, real addresses and specific work beat generic copy when a search engine or AI model decides who to trust.Related work
- Entity
- A named thing — a company, person or place — that search engines and AI systems track as a distinct record rather than a string of words.Why it matters: If your business is not a clear entity, answer engines confuse you with similarly named companies.Related work
- GEO (generative engine optimization)
- The practice of structuring content so AI answer engines such as ChatGPT, Google AI Overviews and Perplexity cite your business when they answer a question in your field.Why it matters: A growing share of buyers now read an AI summary instead of clicking results, so being cited matters as much as ranking.Related work
- Human in the loop
- A deliberate approval step where a person reviews or authorizes before the automation continues.Why it matters: It is how you automate the tedious ninety percent without handing judgment calls to software.
- Idempotency
- Designing a step so running it twice produces the same result as running it once.Why it matters: Without it, a retried automation creates duplicate invoices, records and emails.
- Impression share
- The percentage of available opportunities where your listing or ad actually appeared.Why it matters: It shows how much of your market you are simply absent from.
- Integration
- A connection that lets two systems exchange data automatically, usually through an API.Why it matters: Most 'we need new software' problems are actually two existing systems that were never connected.
- Internal linking
- The deliberate pattern of links between your own pages, showing which pages are most important and how topics relate.Why it matters: It is the cheapest ranking improvement available, and most sites never do it on purpose.
- Landing page
- A page built for a single campaign or offer, with one action and no competing navigation.Why it matters: Sending ad traffic to a general homepage is the most common reason ad budgets underperform.Related work
- Lead scoring
- Ranking inquiries by how closely they match your best customers, so sales works the strongest first.Why it matters: Most teams lose good leads by treating every inquiry as equally urgent.Related work
- Lifetime value (LTV)
- The total profit a typical customer produces across the whole relationship, not just the first job.Why it matters: It sets the ceiling on what you can rationally pay to acquire a customer.
- Local citation
- A mention of your business name, address and phone number on another site, such as a directory or chamber listing.Why it matters: Inconsistent details across citations undercut the map pack rankings you are trying to earn.Related work
- Map pack
- The block of three local business listings with a map that appears above organic results for location-based searches.Why it matters: For most local service searches the map pack takes the majority of clicks before anyone reaches a website.Related work
- Marketing qualified lead (MQL)
- An inquiry that meets an agreed definition of fit and interest before it is handed to sales.Why it matters: Without a shared definition, marketing and sales report different numbers for the same month.
- Mobile-first indexing
- Google evaluates and ranks the mobile version of your page, not the desktop one.Why it matters: Content hidden or dropped on phones effectively does not exist for search.Related work
- Negative keyword
- A term you explicitly exclude so your ads stop showing for it.Why it matters: For local service accounts, negatives usually save more money than any bid adjustment.
- Payback period
- How long it takes for the return from an investment to cover what it cost to build.Why it matters: It is the clearest way to compare an automation build against simply hiring another person.Related work
- Remarketing
- Showing ads specifically to people who already visited your site or engaged with your business.Why it matters: The cheapest audience you can reach is the one that already knows who you are.
- ROAS (return on ad spend)
- Revenue attributed to advertising divided by the amount spent on it.Why it matters: A 4x ROAS on a 20 percent margin still loses money, which is why margin belongs in the conversation.
- Schema markup
- Structured data added to a page in a format search engines and AI systems read directly, describing what the page is about.Why it matters: It is how a machine knows your page describes a plumbing service in Kennewick rather than an article about plumbing.
- Search intent
- What the person actually wants from a query: to learn something, to compare options, or to buy now.Why it matters: A page that answers the wrong intent will not rank no matter how well written it is.
- SEO (search engine optimization)
- Everything done to make a page eligible to rank in organic search results: technical health, content that matches intent, internal linking and external credibility.Why it matters: Organic search is the only channel where the cost per lead falls over time instead of rising.Related work
- Source of truth
- The one system that holds the authoritative version of a given piece of data.Why it matters: When three systems each hold a slightly different customer address, none of your reporting can be trusted.
- Trigger
- The event that starts an automation: a form submission, a paid invoice, a status change, a scheduled time.Why it matters: Choosing the right trigger is what separates an automation that runs quietly from one that fires at the wrong moment.
- Webhook
- A message one system sends to another the moment an event happens, instead of the second system polling for changes.Why it matters: It is what makes automations feel instant rather than running on a fifteen-minute delay.
- Workflow automation
- Software that performs a defined sequence of steps between systems when a trigger fires, without a person moving the data.Why it matters: It removes the repetitive typing that consumes staff hours and quietly introduces errors.Related work
Method
How these definitions are written
Most glossaries define a term by restating it in slightly different jargon. Every entry here does two things instead: it says what the term means in plain English, then states the consequence for a business owner making a decision. If a definition cannot produce a consequence, the term probably does not deserve space in a proposal.
Terms are grouped into five areas — search, web, automation, advertising and measurement — because the same word often means different things depending on who is using it. The filters exist so you can read only the part relevant to the conversation you are in.
Where a term connects to work we do, there is a link to the page that explains that work in depth. The definition stands on its own regardless; you are not required to click anything to get the answer.
Definition, then consequence
Knowing that GEO means generative engine optimization is useless on its own. Knowing that buyers increasingly read an AI summary instead of clicking results is what changes the plan.
Grouped by area
Search, web, automation, advertising and measurement. Filtering keeps a proposal review focused rather than turning it into a vocabulary test.
No hidden jargon
Where a definition needs another term, that term is defined here too. Nothing is explained using a word this page does not cover.
Next step
Use this when you read a proposal
The point of the glossary is not vocabulary — it is leverage in the conversation where someone is asking for your money.
- 01
Ask for the consequence
For any term in a proposal, ask what changes in the business when it improves. If the answer is another term, the line item is decoration.
- 02
Insist on three numbers
Cost per lead, close rate and lifetime value. Any plan that cannot be evaluated against those three cannot be evaluated at all.
- 03
Separate deterministic from AI
Most useful automation is deterministic and predictable. Ask specifically where a language model is involved and what limits are placed on it.
Questions
Frequently asked
Because most agency proposals rely on the client not asking what a term means. Every definition here is written so you can push back on a proposal that uses the word loosely.
SEO makes a page eligible to rank in a list of blue links. GEO makes the same page easy for an AI answer engine to quote and attribute. They overlap heavily in technical work and diverge in how content is structured — GEO rewards direct, self-contained answers with clear entities and sources.
Cost per lead, close rate and lifetime value. With those three you can evaluate any channel. Everything else on this list is diagnostic detail that explains why those three moved.
No. Most useful automation is deterministic: a trigger fires, defined steps run, the same thing happens every time. AI is only worth adding where the input is unstructured — reading a message, summarizing a call, drafting a first reply.
We add terms as they start showing up in real client conversations, particularly around AI search where the vocabulary is still settling.
