TermAbbreviationDefinition & usage
Click-through rate
CTR

The percentage found by dividing the number of clicks an ad received by its number of impressions: clicks / impressions × 100. 1,000 impressions and 40 clicks means a 4% CTR.

An early signal of how well the ad matches user intent. There's no universal "good CTR" — channel, query, placement, and campaign objective all change what counts as good. If a high CTR isn't converting, there may be a mismatch between the ad's promise and the landing page or audience.

Cost per click
CPC

The average cost found by dividing total ad spend by the number of clicks received. $2,000 in spend and 500 clicks means a $4 CPC.

Shows the cost at which you're buying traffic — but a cheap click isn't always valuable traffic. Bid or budget decisions shouldn't be made without reading CTR, conversion rate, and CPA together.

Cost per mille
CPM

Calculated by dividing total ad spend by impressions and multiplying by 1,000. $5,000 in spend and 1 million impressions means a $5 CPM.

Used to compare the cost of buying media visibility. A low CPM alone doesn't indicate quality reach; it should be evaluated together with audience fit, frequency, and downstream actions.

Conversion
-

The valuable action expected from a user after seeing an ad — it can be a form, a call, a purchase, or a quote request.

The core concept of measurement setup, since it determines what the campaign optimizes for.

Conversion rate
-

The percentage found by dividing the number of conversions by the number of clicks or interactions measured. 25 conversions from 500 clicks means a 5% conversion rate.

Shows how efficiently traffic turns into the expected action. Traffic source, bid, landing page, and measurement accuracy all affect the result together; a high rate doesn't necessarily make up for low volume.

Return on ad spend
ROAS

Calculated by dividing revenue or conversion value attributed to ads by ad cost. $50,000 in revenue from $10,000 in spend is a 5.0, or 500%, ROAS.

Shows revenue efficiency from ads; it doesn't include product cost, operations, returns, tax, or sales team expenses. A high ROAS is therefore not a profitability guarantee and should be compared against the business's break-even threshold.

Cost per action
CPA

Calculated by dividing total ad spend by the number of measured conversions. $12,000 in spend and 60 conversions means a $200 CPA.

Shows the acquisition cost of actions like forms, leads, or purchases. The result depends directly on how conversion is defined; if a low-quality lead also counts as a conversion, a low CPA can be misleading.

Campaign
-

The level where core settings like budget, goal, bid strategy, and network are managed.

Used to separate different goals, budgets, or locations.

Ad group
-

The level where keywords and ads with similar intent are managed together.

Creates narrower clusters within a campaign to match ad copy with search intent.

Keyword
-

The targeting term that determines which search intents an ad can match.

Not the same thing as the actual user query; it's read together with match type and the search terms report.

Quality Score
-

A diagnostic score reflecting expected click-through rate, ad relevance, and landing page experience.

Not a single value that directly explains Ad Rank — it's an indicator for understanding which quality component needs improvement.

Impression share
IS

The ratio of impressions your ads actually received to the total impressions they were eligible to receive under your targeting and approval settings. For example, a 60% impression share means your ad showed in roughly 60 of every 100 eligible opportunities.

Shows how much of the available demand you're reaching; when it's low, read Search lost IS (budget) and Search lost IS (rank) together. A high impression share alone doesn't mean sales or profitability.

Search lost IS (budget)
-

The estimated share of Search Network impressions missed due to budget limitations.

Read to understand whether low visibility stems from a budget constraint rather than bid or quality.

Search lost IS (rank)
-

The estimated share of Search Network impressions missed due to ad rank.

Used to understand whether a visibility problem is related to bid, quality, ad relevance, or landing page experience.

Cost per view
CPV

The cost calculated for one view or play of a video ad.

Used in video campaigns to read view cost and attention level instead of clicks.

Target CPA
-

An automated bid strategy that works toward a target cost per conversion.

If conversion volume and conversion quality aren't sufficient, the system may optimize toward the wrong signal.

Target ROAS
-

An automated bid strategy that tries to hit a target return rate based on conversion value.

Meaningful when revenue or conversion value data is entered accurately; lead campaigns need a value model set up separately.

View rate
-

The share of a video ad's impressions that resulted in a view.

Helps understand how well the video creative holds attention in the first few seconds.

Absolute top impression share
ATIS

The ratio of impressions your ad received in the very top, most prominent position to the eligible top-impression opportunities.

Used especially in Shopping and search visibility to track not just whether you appear, but how prominently you appear.

Broad match
-

A match type that can match broader queries related to the keyword's meaning.

Can be powerful for discovery and volume; needs to be controlled with negative keywords and conversion tracking.

Average daily budget
-

The average daily spend target for a campaign.

Budget should be read as an average spending logic over a period, not as a strict daily cap.

Ad Rank
-

The ranking value that affects where and under what conditions an ad appears in the auction.

Bid, quality, thresholds, competition, and auction context are all read together; the highest bid doesn't always mean the top position.

Phrase match
-

A match type that matches queries that preserve the keyword's meaning.

Offers a scope that is more controlled than broad match and more flexible than exact match.

Exact match
-

A match type that matches narrower queries carrying the same meaning as the keyword.

Used for control and clear intent; may be more limited on the volume side.
