Publisher

An ad publisher is a person or website owner who has been registered or approved by the advertising application manager to activate AdSense ads on their site. 

The publisher that serves google ads is called the google adsense publisher. 

Previously, google adsense publishers had to register with Google Adsense and could only serve Google ads on their website after the application was approved. 

Each google adsense publisher is only allowed to have one google adsense account, but they activate google ads on all their sites that meet the google adsense program requirements.

Ad Unit

What is meant by Ad Units is the AdSense ad itself. Ad Units come in several types and sizes. The most common is the text ad type. 

When a visitor clicks on this ad unit, then (if valid) the advertiser will get revenue according to the CPC value.

Link Units

Link Units are almost the same as Ad Units, it's just that they are similar to the menu format we usually encounter on web sites. 

What distinguishes Link Units from Ad Units is that when a visitor clicks on this ad, he will be directed to the search results page on the Google search engine. 

New publishers will receive revenue from visitors to one of the Ad Units on the page. In practice, Link Units are proven to generate more revenue than regular Ad Units.

AdSense for Content

AdSense for Content is an AdSense ad that is placed on a page. The advertisements that appear are advertisements related to the content of the page. Or the term uses a contextual concept. Ad Units and Link Units are included in AdSense for this content.

Alternative Advertising

With AdSense for content, ads don't always appear. The reason, among others, could be because the stock of advertisements related to the content of the site had run out or Google could not predict what the site actually contained. If this happens, by default, the bad one is public service advertising or what is known as PSA (Public Service Ads). Because of the type of donation, if clicked, this ad does not generate anything for the publisher. To fix this, Google allows us to stop Alternative Ads or alternative ads. If the regulated Ad Unit has been set up using Alternative Ads, then the Ad Unit cannot appear, what appears is the ad that was previously set.

Channel

Channels is a kind of label that can be assigned to Ad Units, Link Units, AdSense for Search, and Referrals. One ad unit can have more than one label, and conversely, one label can be used for more than one ad unit. On the Google AdSense report page, the report results will be grouped by Channels, so that the use of Channels will greatly facilitate publishers to analyze their AdSense performance. Usually, the publisher will give the same Channels name to the ad units on one site. If you want more details, it's okay to provide a different Channel name for each ad unit on each site. Keep in mind, the maximum number of Channels currently allowed is 200 channels.

Pageviews

Page Impressions is a number that shows the number of times a page containing Ad Units was opened by a visitor. The value is not bought by the quantity of Ad Units found on the relevant page.

Click

Clicks are the number of clicks on the publisher's Ad Units. Within the AdSense report page, publishers can see the total clicks they have received, based on their Ad Units or Channel.

CTR (Click-Through Rate)

CTR is the ratio in percentage between the number of clicks received by an Ad Units and the number of views of the Ad Units. For example, one Ad Units that is asus 60 times and is clicked 10 times has a CTR value of 25% (10:60).

CPC (Cost Per Click)

CPC is the amount of money a particular Ad Units membership issuer will get by clicking. The CPC value of each Ad Unit is different and is determined by many factors, including the performance and quality of the publisher's site. In general, however, the maximum possible value is 20% of the dynamic bid value offered by the advertiser.

eCPM (Effective CPM)

eCPM or CPM (Cost Per Million) is the result of dividing the total revenue of the publisher with the number of page impressions (per 1,000) he gets from his ads. 

eCPM = (Estimated Earnings / Number of total impressions) * 1000

For example, a publisher making USD 300 out of 50,000 impressioni would have a CPM value of USD 6 (USD 300 divided by 50).

In Summary, CPM is the rate which the advertiser is willing to pay for a 1000 impressions and eCPM is the earning of the publisher per 1000 impressions.

eCPM is very helpful for publishers to evaluate and optimize their monetization by monitoring ad revenue generated from campaigns.

It is important that publishers and advertisers know the difference so that they can accurately measure the revenue performance and the campaign costs for better forecasting. 

Page RPM

Page revenue per thousand impressions (RPM) is calculated by dividing your estimated earnings by the number of page views you received, then multiplying by 1000.

Page RPM = (Estimated earnings / Number of page views) * 1000

For example, if you earned an estimated $0.15 from 25 page views, then your page RPM would equal ($0.15 / 25) * 1000, or $6.00.

Page CTR

The page clickthrough rate (CTR) is the number of ad clicks divided by the number of page views.

Page CTR = Clicks / Page views

For example, if you received 2 clicks for 250 page views, your page CTR would be 0.8%. (2/250=0.8%)
