Google AdSense Glossary: Metrics, Ads and Payments for Beginners

AdSense terminology is easier when grouped into who pays for ads, how ads are counted, how earnings are compared and when money is paid. Pageviews count page viewing, ad impressions count ads that have loaded and begun rendering, and RPM expresses earnings per 1,000 of a specified unit. This guide explains 63 terms from application to payment, with simple examples.

Advertisers, publishers and auctions: where do ads and money come from?

AdSense helps website owners earn from advertising space. For the overall process, see how AdSense works and how to get started. All numerical examples here are hypothetical explanations, not actual site results or earnings promises.

Publisher means the person or organization operating the content or site where ads appear. If you run a cooking blog and show AdSense ads, you are the publisher. The term refers to the operator, not the reader.

Advertiser means the business paying to promote a product or service. A cookware seller might advertise on a cooking blog. Google Ads helps advertisers run campaigns; AdSense helps publishers monetize space.

Ad auction is the competition that selects an ad for available space. Several advertisers may want the same space, and bids and applicable auction conditions determine the selection. Publishers do not choose a fixed price or every ad shown to every visitor. See Google's explanation of the auction.

Pageviews, impressions and requests: what is being counted?

Pageviews (PV) count page viewing. In AdSense, they count views of pages displaying Google ads. One person opening two articles can produce two pageviews, so this is not a visitor count. Google Analytics 4 (GA4) views can differ because of measurement scope and consent conditions.

Ad impressions count ads loaded onto a device that have begun rendering. One page may produce several impressions, or fewer because of blocking, loading or serving conditions. Two pages with three ad spaces each do not guarantee six actual impressions.

Clicks count ad clicks, not clicks on the blog menu or ordinary links. One person can click more than once, and invalid activity can be adjusted. Clicks are neither unique visitors nor finalized earnings.

Ad requests count requests from the site for Google to supply ads, rather like placing an order at a restaurant. A request does not prove an ad was returned or became visible on screen. Use the official ad request definition to distinguish it from an impression.

Coverage is the percentage of ad requests that returned at least one ad. If 1,800 of 2,000 requests return ads, coverage is 90%. The denominator is requests, not visitors, and it does not measure whether an ad was visible on screen. See Google's coverage calculation.

Remember the sequence: requested, loaded and beginning to render, then meeting on-screen viewability conditions. For a large discrepancy, see why AdSense impressions can be lower than pageviews.

CTR, CPC, CPM, RPM and Active View: reading ratios and rates

Click-through rate (CTR) compares clicks with the relevant base. Ad CTR = ad clicks ÷ ad impressions × 100. Ten clicks from 2,000 impressions means 0.5%. Always check whether a report says ad CTR or page CTR.

Page CTR = ad clicks ÷ pageviews × 100. Ten ad clicks from 1,000 pageviews means 1%. With the same ten clicks and 2,000 ad impressions, ad CTR is 0.5%. Both are correct because page CTR and ad CTR have different denominators.

Cost per click (CPC) is an amount associated with one click. A rate of US$0.20 per click is based on clicks. Advertiser cost and publisher earnings need not be identical because of revenue sharing and other conditions. Do not assume all earnings equal clicks multiplied by CPC.

Cost per thousand impressions (CPM) is the cost for 1,000 ad impressions. A US$2 CPM does not mean US$2 per single impression. Its base differs from CPC. Google describes AdSense for content publisher payments as impression-based, so no clicks does not necessarily mean no earnings. Distinguish products and formats.

Revenue per thousand (RPM) expresses earnings on a comparable scale. It resembles comparing sales per 1,000 customers rather than total sales at differently sized stores. In AdSense, however, the unit is the specified pageviews or impressions, not people. RPM is not a payout promise or bank balance.

Page RPM = estimated earnings ÷ pageviews × 1,000. US$30 from 10,000 pageviews gives US$3. This describes earnings equivalent to US$3 per 1,000 pageviews for that dataset; it does not guarantee a fixed US$3 for every future thousand.

Impression RPM = estimated earnings ÷ ad impressions × 1,000. The same US$30 from 20,000 impressions gives US$1.50. A page RPM of US$3 and impression RPM of US$1.50 can reflect different denominators rather than an error. See the official RPM explanation.

Metric Formula Question answered
Ad CTR Clicks ÷ ad impressions × 100 What share of ad impressions resulted in clicks?
Page CTR Clicks ÷ pageviews × 100 How do ad clicks compare with pageviews?
Page RPM Estimated earnings ÷ pageviews × 1,000 What were earnings per 1,000 pageviews?
Impression RPM Estimated earnings ÷ ad impressions × 1,000 What were earnings per 1,000 ad impressions?

Active View Viewable is the share of measurable impressions that meet viewability conditions. Six hundred qualifying impressions out of 1,000 measurable ones means 60%. Google describes a general criterion of at least 50% of an ad's area on screen for at least one second. Active View distinguishes loading from viewability, but does not prove a person paid attention.

Compare the same period, site, country, device and denominator. A high single metric does not automatically mean good performance. Making ads resemble buttons to raise CTR can create policy problems.

Estimated earnings, finalized earnings and adjustments

Estimated earnings are provisional report figures, like writing an expected payment in a household budget. Processing and invalid-activity filtering can change them. They are not immediately withdrawable funds.

Finalized earnings are verified earnings posted to the payments account. An estimate of US$32 might become US$30 after finalization. Finalization does not mean payment that day: thresholds, holds and the payment cycle still apply.

Adjustments to earnings add or subtract amounts for reasons such as processing or invalid activity. Read the transactions and stated reason when a deduction appears. Google explains that invalid-activity adjustments can occur during finalization or after payment. A difference alone does not identify its cause.

Ad formats and placement: what appears where?

Appearance, placement method and sizing behavior are separate dimensions. A display unit can be responsive and manually placed. Availability varies by site, language and device, so check the actual account options.

Auto ads let Google analyze a site and place ads in suitable locations. They reduce the need to place every ad manually. Publishers still need to check enabled formats, exclusions and reading comfort.

Ad unit is a manageable set of advertising settings. You could create a unit for the middle of articles and insert its code where needed. One unit does not necessarily mean one ad from one advertiser.

Display ads are general-purpose ads using images, text or other supported media. Think of an ad box beside or between article content. Actual size and location depend on settings and screen conditions.

Responsive ads adapt their size to the device and available space. A wide desktop placement can look narrower on a phone. Responsiveness describes presentation, not a separate revenue model.

In-feed ads fit between items in a feed, such as article or product lists. An ad card among article cards is an example. Matching the layout must not mislead readers about its advertising nature.

In-article ads are native units designed for placement between article paragraphs. They are not the same as site-wide Auto ads. Understand them as a particular unit whose code is placed within an article.

Multiplex ads combine several ads in a grid. They can resemble recommendation cards, but are not the site's own related-article list. See the ad unit types for display, in-feed and in-article distinctions.

Anchor ads are overlay ads attached to the top or bottom edge of the screen. They can remain at the edge while a reader scrolls. They differ from an ad placed at a fixed point inside the article.

Vignette ads cover much of the screen at suitable moments, such as navigation between pages, with a dismissible experience. A large banner between paragraphs is not automatically a vignette.

Side rail ads appear beside the page in the margins of wide screens. Do not expect the same placement on a phone without enough side space.

Ad intents place relevant links, anchors or chips in content. Interaction opens a dialog containing related advertising and potentially other related content. These are not ordinary internal links. See how ad intents work; there is no reason to force repetitive product mentions into an article.

Ad load describes the amount of advertising shown on a page, not loading speed. Current Auto ads settings include maximum in-page ad count and minimum spacing. An older tutorial's exact “ad load” control may not appear under that name.

Excluded areas are parts of a page where in-page Auto ads should not appear, for example within an ingredients section. This does not automatically remove every manually inserted ad code.

Excluded pages are URLs or site sections excluded from Auto ads. Their scope differs from excluding an area within one page. Consult Auto ads settings, then review the preview and live site after changes.

Approval and site setup terms

Site approval means a site has passed review and is eligible to show ads. Signing up or adding code alone is not approval. Approval also does not guarantee traffic or earnings.

Site review checks content and policy compliance. Statuses such as “Getting ready” and “Ready” mean different things, so read the Sites page and requested actions. There is no guaranteed approval formula based on a fixed article count or number of days.

Site connection means adding the site to the account and confirming the connection using the instructed method. Google's connection guide distinguishes this from review: a verified connection may still await approval.

Ad code is the program snippet that enables a site to request and display ads. It adds advertising functionality rather than article content. Incorrect or duplicate installation can cause display issues; check the supplied code and the theme or plugin insertion method.

Publisher ID uniquely identifies an AdSense account. An illustrative format is pub-1234567890123456; use your actual account value. Multiple units can share this ID. Do not copy another publisher's identifier.

Ad slot ID identifies a particular unit in the code, typically in data-ad-slot. Publisher ID answers “whose account?”; slot ID answers “which unit?”. Finding your publisher ID also includes a code example.

ads.txt lists sellers authorized to sell the site's advertising space. Think of an approved seller list, usually available at the site's root /ads.txt. It is not the code displaying an ad. Google recommends ads.txt, but having the file does not by itself complete site approval.

Ad crawler is an automated program reading site content for advertising purposes. Its purpose differs from search indexing. A successful ad crawl does not guarantee high search rankings.

Crawler errors occur when a crawler cannot access or read a page, perhaps because of login restrictions, server errors or blocking. Check the reported URL in an ordinary browser and inspect relevant access or server settings. Distinguish affected pages from site-wide problems.

Policies and invalid traffic

Program policies are ongoing participation rules covering content, placement and click encouragement, among other areas. They apply after approval too. Check the current AdSense Program policies.

Policy center is where account or site issues and required actions are shown. If ads decrease, inspect the notice and affected scope first. A page-specific correction and an account-wide problem require different handling.

Policy violation means breaking an applicable rule, for example explicitly asking visitors to click ads. Fix the stated cause and affected pages, then follow any available review procedure. Not every restriction represents the same kind of violation.

Ad serving limit restricts the number of ads that can be shown, for example during traffic-quality assessment or because of invalid-traffic concerns. It is not the same as permanent account closure, and no arbitrary removal date can be promised. Read Google's serving-limit guidance and your account message.

Invalid traffic includes clicks or impressions that can improperly inflate advertiser costs or publisher earnings. It includes more than bots: own-ad clicks and accidental clicks can qualify. A real human visit is not automatically valid advertising activity.

Invalid click is an ad click treated as invalid activity. Repeated clicking to generate earnings or asking friends to click are examples of problematic conduct. Never click your own live ads, even for testing.

Accidental click happens by mistake rather than genuine interest in an ad. An ad beside a download button or a sudden layout shift can cause one. Separate ads from controls even without deliberate deception. Google's invalid traffic definition includes accidental clicks.

Personalized ads and CMPs: understanding consent

Personalized ads use information such as prior activity or inferred interests to select advertising. Travel-interest information is an example. This is different from selecting an ad solely for the current article topic.

Non-personalized ads use context, such as current page content or coarse location, rather than personalization based on past behavior. This does not mean no data, cookies or consent requirements. See personalized versus non-personalized ads.

Consent management platform (CMP) presents privacy choices and manages consent or refusal, doing more than simply displaying a notice. Google's certified CMP requirements concern personalized advertising to users in the European Economic Area (EEA), UK and Switzerland, among the relevant conditions. Check visitor location as well as publisher location. Installing a CMP does not automatically satisfy every privacy obligation.

Payments and verification: when can earnings be received?

Payments profile records payment-related identity details such as the recipient's name and address. It answers “who gets paid?”. It must match the actual recipient and is not an ad unit or website address.

Payments account is the ledger for a product's earnings, balance, transactions and payments. It answers “which earnings ledger?”. AdSense and YouTube payments accounts can be separate, each with its own threshold to meet.

Identity verification establishes who the recipient is, using documents or steps requested in the account. Identity and address checks have different purposes. Timing and methods depend on location and account instructions.

Address verification confirms the payments address. Postal PIN verification is a familiar method, but separate address verification may be unnecessary after online identity verification in some locations. Check Payments → Verification check for your actual requirements.

PIN (Personal Identification Number) is a verification number. In the postal process, enter Google's mailed six-digit number in the instructed account screen. It is not a bank password or publisher ID. Follow the address verification guide; do not guess a code.

Payment threshold is the balance needed for payment. The default USD threshold is US$100, but currencies differ and publishers can raise their threshold. It differs from verification and payment-method selection thresholds. Consult Google's currency-specific thresholds.

Payment hold pauses sending money. Missing verification or information, or a publisher's own temporary hold, are possible reasons. Reaching the threshold does not automatically remove a hold. Resolve the reason shown on the Payments page.

Payment schedule is the monthly sequence of finalization and payment. Typically, the previous month's earnings finalize early in the next month and qualifying payments are issued between the 21st and 26th. Under Google's payment timeline, issue date and bank arrival can differ because of weekends, holidays and payment method.

Payment method is how you receive money, such as a bank transfer. Availability depends on country and account conditions. Choose an available option and provide real recipient details rather than copying instructions for another country.

Outstanding earnings or balance means money remaining unpaid in the account. For example, US$70 can accumulate with a later month's earnings toward a US$100 threshold, subject to other conditions. The current month's estimated report earnings need not match the payments balance.

Tax information identifies the recipient and relevant residence or tax details. Required forms and withholding depend on country, income type and individual conditions. Follow Google's tax information instructions and account requests truthfully. Submitting information to AdSense does not complete every tax obligation in your country.

Practice with a hypothetical report and compare confusing terms

These figures use one site, period, currency and measurement scope. They illustrate reading a report and are neither average performance nor targets.

Report item Hypothetical value How to read it
Pageviews 10,000 Not necessarily 10,000 visitors
Ad impressions 20,000 Ads loaded and beginning to render
Ad clicks 100 Not ordinary link clicks
Estimated earnings US$30 Not yet a finalized payout
Page CTR / ad CTR 1% / 0.5% 100 ÷ 10,000 and 100 ÷ 20,000, each × 100
Page RPM / impression RPM US$3 / US$1.50 30 ÷ 10,000 and 30 ÷ 20,000, each × 1,000

“RPM is US$3, so earnings are US$3” is incorrect here. The example earnings are US$30; US$3 expresses them per 1,000 pageviews. Likewise, the two CTRs divide the same clicks by different bases.

Often confused Key distinction
Pageviews / visitors Viewing events / people or users
Request / impression / viewability Asked for / started rendering / met screen conditions
CPM / RPM Advertising cost rate / normalized earnings metric
Auto ads / in-article ads Placement method / particular unit format
ads.txt / ad code Authorized seller list / requesting and displaying ads
Finalized earnings / payment Settled earnings / money issued under payment conditions
Identity / address / payment threshold Who / where / required balance
  1. When applying: open Sites → your site and read connection and review status. Detected ads.txt alone is not approval.
  2. When few ads appear: distinguish Policy center notices, requests and coverage, impressions and viewability. Do not test by clicking ads.
  3. When comparing earnings: align period and currency and read pageviews, estimated earnings and page RPM together. Check whether country or device mix changed.
  4. When waiting for money: check Payments → Payments info and Verification check for the account, finalized balance, holds, required verification and payment method. Do not rely only on estimated report earnings.

Rather than memorizing every acronym, check the denominator and the purpose of each account screen. Ask whether the number counts users, pages or ads, and whether an amount is estimated earnings, a finalized balance or an actual payment.
