Google Ads terminology can feel overwhelming when you’re new to the platform because the interface and reports contain many terms that are not always self-explanatory. Words such as campaign, ad group, keyword, search term, Ad Rank, Quality Score, CPC, CPA, ROAS, conversion, and impression share each describe a different part of advertising and measurement. Understanding these terms makes Google Ads settings, reports, and performance data much easier to interpret.
1. Account Structure Terms
1.1 Google Ads Account
A Google Ads account is the top-level account that contains advertising activity, including campaigns, billing information, settings, and performance data.
1.2 Manager Account
A manager account, formerly commonly called an MCC, allows agencies or businesses to manage multiple Google Ads accounts from one place. A manager account does not itself serve ads.
1.3 Campaign
A campaign is a major organizational level where settings such as budget, campaign type, location, and other advertising controls are configured. Campaigns contain one or more ad groups.
1.4 Ad Group
An ad group sits inside a campaign and organizes related ads and their associated targeting, such as keywords in Search campaigns.
1.5 Ad
An ad is the advertising message shown to users. It can contain elements such as headlines, descriptions, and assets and directs users to a destination page.
2. Keyword and Search Terms
2.1 Keyword
A keyword is a word or phrase selected by an advertiser to help determine which searches may make an ad eligible to show in Search campaigns.
2.2 Search Term
A search term is the actual word or phrase a user enters into Google. It may differ from the keyword selected by the advertiser. A search term may also be referred to as a search query in some contexts. The important distinction is that the keyword is selected by the advertiser, while the search term comes from the user.
2.3 Keyword Match Types
Match types control how closely a user’s search needs to relate to a keyword for an ad to be eligible.
- Broad match: Can match searches related to the keyword’s meaning.
- Phrase match: Can match searches that include the meaning of the keyword phrase.
- Exact match: Can match searches that closely relate to the specific meaning of the keyword.
2.4 Negative Keywords
Negative keywords tell Google Ads which searches should not trigger an ad, helping prevent ads from showing for unwanted or irrelevant searches.
3. Auction Terms
3.1 Google Ads Auction
The Google Ads auction is the automated process used when an eligible advertising opportunity occurs. It determines which ads can show and their position relative to other eligible ads.
3.2 Ad Rank
Ad Rank is a value used to determine whether an ad can appear and where it may appear. It considers factors such as the bid, ad quality, and the expected impact of ad formats and other factors.
3.3 Quality Score
Quality Score is a keyword-level diagnostic tool, not an input directly used in the ad auction. It provides an indication of the quality of a keyword based on expected click-through rate, ad relevance, and landing page experience. Ad Rank uses auction-time ad quality and other factors, so Quality Score and Ad Rank are not the same measurement.
3.4 Maximum CPC Bid
A maximum CPC bid is the maximum amount an advertiser is willing to bid for a click when using a bidding approach that uses a CPC bid.
3.5 Actual CPC
Actual CPC is the amount an advertiser actually pays for a click. It can be lower than the maximum CPC bid because the final amount is determined by the ad auction.
4. Bidding and Budget Terms
4.1 Daily Budget
A daily budget is the average amount an advertiser sets for a campaign to guide its daily advertising spend.
4.2 Bid
A bid is the amount used to compete in an ad auction. Depending on the bidding strategy, bids can be focused on actions such as clicks, conversions, or conversion value.
4.3 Bid Strategy
A bid strategy is the method Google Ads uses to set or guide bids based on an advertiser’s selected objective.
4.4 Smart Bidding
Smart Bidding refers to Google’s automated bidding strategies that use machine learning to optimize for conversions or conversion value at auction time.
4.5 Auction-Time Bidding
Auction-time bidding means Google Ads can adjust a bid for an individual auction using signals available at that moment. It is a key characteristic of Smart Bidding.
4.6 Target CPA
Target CPA is a conversion-focused bidding strategy that aims to generate conversions around an advertiser’s chosen average cost per acquisition.
4.7 Target ROAS
Target ROAS is a conversion-value-focused bidding strategy that aims to achieve a specified return relative to advertising spend.
4.8 Maximize Conversions
Maximize Conversions is a bidding strategy that aims to generate as many conversions as possible within the available budget, without setting a specific Target CPA.
4.9 Maximize Conversion Value
Maximize Conversion Value aims to generate as much total conversion value as possible within the available budget, without setting a specific Target ROAS.
5. Ad and Asset Terms
5.1 Ad Assets
Ad assets are additional pieces of information or content that can appear with an ad, such as sitelinks, callouts, structured snippets, or images.

Demographic targeting uses available characteristics such as age, gender, and household income to refine advertising eligibility.
6.6 Targeting
Targeting means actively restricting ad delivery based on a selected audience or targeting criterion.
6.7 Observation
Observation allows advertisers to monitor how an audience segment performs without restricting ad delivery to that audience. This is the key difference between observation and targeting.
7. Ad Visibility and Interaction Terms
7.1 Impression
An impression is counted when an ad is shown.
7.2 Impression Share
Impression share is the percentage of eligible impressions that an ad actually received.

8.4 Conversion Rate
Conversion rate is the percentage of relevant interactions that result in conversions. In common Search reporting contexts, it is calculated from conversions divided by interactions such as clicks.
8.5 Return on Ad Spend (ROAS)
ROAS measures conversion value relative to advertising cost.
For example, if an advertiser spends $100 and receives $500 in conversion value, the ROAS is 5:1, or $5 in conversion value for every $1 spent.
8.6 Conversion Value
Conversion value is the monetary value assigned to conversions and can be used to evaluate value-based performance and calculate metrics such as ROAS.

9.2 Conversion Action
A conversion action is a specific conversion that has been configured for measurement, such as a purchase or lead.

9.4 Primary Conversion Action
Primary conversion actions are used by Google Ads automated bidding strategies for optimization when they are included in the campaign’s conversion goals.

Secondary conversion actions can be measured and reported but are generally not used directly for automated bidding optimization.

12.5 Bid Strategy Report

13. Important Google Ads Terminology Updates
13.1 Target CPA and Target ROAS Naming
Google has updated how certain conversion-focused bidding options are labeled in Google Ads. Advertisers may encounter Target CPA and Target ROAS as the current names where older documentation may describe these options as Maximize Conversions with a Target CPA or Maximize Conversion Value with a Target ROAS. The naming change does not represent a change in the underlying bidding behavior.

AI Max for Search campaigns is a suite of AI-powered enhancements available within Search campaigns rather than a separate campaign type. It includes features related to search-term matching, text customization, and Final URL expansion.
