Google Ads Words in Plain English (A Jargon Decoder for Busy Owners)

The money words

Budget
The cap on what you are willing to spend in a day or month. A budget is a limit, not a promise that Google will spend every dollar wisely.

Bid
How much you are willing to pay for a result (often a click) in the auction. You can set bids yourself or let automated bidding use your goals.

CPC (cost per click)
Roughly what you pay when someone clicks your ad. It is not what you pay for a customer.

CPA / CPL (cost per acquisition / cost per lead)
What you paid divided by conversions or leads—as those words were defined in the account. If “lead” means a spam form, a low CPL can still be a bad deal.

ROAS (return on ad spend)
Revenue attributed to ads divided by ad spend. Only meaningful if revenue tracking is real. Many service businesses should not pretend they have clean ROAS on day one.

Impression
Your ad showed on a screen. Showing is not a phone call.

Click
Someone clicked. Curiosity is not a booked job.

The structure words

Campaign
A folder with its own budget and goal settings. Think “Emergency plumbing – search” as a campaign name style.

Ad group
A smaller folder inside a campaign that keeps related search themes and ads together.

Keyword
A word or phrase you choose to help decide when your search ad can show. Close variants and matching behavior can still surprise you—review search terms.

Search terms
What people actually typed or spoke. This report is where waste often hides.

Negative keyword
A phrase you block so your ad does not show for irrelevant searches (for example, “free” or “DIY” if you do not want those).

Ad / ad assets
The words (and extras like sitelinks) people see. Clear beats clever.

The “did it work?” words

Landing page
The first page people hit after the click. It should continue the promise in the ad.

Conversion
An action you told Google to count as valuable—form submit, call, booking, and so on. The platform does not invent your business definition. If conversions are duplicated or too soft, bidding learns the wrong lesson. Deeper reading: Primary vs. Secondary Conversion Actions and Duplicate conversions.

Primary conversion
A conversion included in the main optimization goal—what automated bidding tries to get more of.

Secondary conversion
Tracked for learning, not as the main bidding target.

Attribution
The story of which click or channel gets credit for a conversion. Stories are incomplete. Treat them as directional.

Lead
In everyday business talk: someone who might become a customer. In ads reports: often just a form or call event. Ask which meaning people are using. (See also: what a “lead” actually means.)

The tracking words (worth knowing)

Tag / pixel
A small piece of code that helps measure actions on your site.

Google tag / gtag / GTM (Google Tag Manager)
Ways to install and organize measurement code. You do not need to configure them yourself—but someone accountable should.

GA4 (Google Analytics 4)
A site analytics product. Its numbers often will not match Google Ads exactly. That can be normal when definitions differ.

Call tracking
Systems that help tell which ads led to phone calls. Useful when set up carefully; messy when calls are counted twice.

The trust words

Admin access / ownership
Whether your business can enter the account, see billing, and keep history if a vendor leaves.

MCC
A manager account some agencies use to link to client accounts. Linking is fine; locking you out is not.

Optimization
Changes meant to improve results. Real optimization is explained in plain language. “We optimized” with no detail is a fog machine.

Questions you can ask any provider (copy/paste)

1. What exact action counts as a conversion—and can I see a test?
2. Who owns the Google Ads account login and billing?
3. Which search terms spent money last week, and which did we block?
4. How many inquiries reached our phone or inbox—not only the Ads column?
5. What will you change next, and how will we know it helped?
