Google Ads glossary

Google Ads glossary: key terms, explained

Each term is defined in one sentence, explained in a few lines, then illustrated with an example. The thread stays the same: only pay for the clicks that can lead to a purchase.

Every term in the glossary

12 terms

  • Ad group: An ad group holds the ads and keywords that share one theme inside a Google Ads campaign.
  • Bid: A bid is the most you are willing to pay for a click on your Google Ads ad, and you often pay less.
  • Click-through rate (CTR): Click-through rate, or CTR, is the share of people who click your ad out of those who see it: the number of clicks divided by the number of impressions, the times your ad was shown.
  • CPC (cost per click): CPC, or cost per click, is the amount you pay each time someone clicks your Google Ads ad.
  • Landing page: A landing page is the page on your site that a person reaches after clicking your ad.
  • Match types: Match types (broad, phrase, exact) set how far a search can drift from your keyword and still trigger your ad.
  • Negative keyword: A negative keyword is a word or phrase that stops your ad from showing on searches that contain it.
  • Quality Score: Quality Score is a 1 to 10 rating given to each keyword: it estimates the quality of your ads and landing page compared with other advertisers.
  • ROAS: ROAS, short for return on ad spend, is the value of the conversions you got (sales, quote requests) divided by what you spent on advertising.
  • Search intent: Search intent is what a person really wants to get when they type a query: to learn, to find a site, to compare or to buy.
  • Search term: A search term is the word or set of words a person actually typed into Google before seeing your ad.
  • SERP: The SERP, short for search engine results page, is the page a search engine shows after a query: ads, organic results and other blocks.

Why a Google Ads glossary?

The same words come up in every Google Ads decision: keyword, bid, intent, quality. A misunderstood word is paid for by the click. Here, each definition follows the official Google Ads Help and points to its source.

If you are starting out, read search intent first, then negative keywords and match types. Those three ideas decide who sees your ad.

Go from definition to practice

The free Google Ads tools apply these ideas to your own keywords: intent, exclusions, budget, ROAS.
