In analytical web tools as Google AdSense publisher, Pageviews and impressions are calculations that help you track visitor behavior on your website which known as Google Analytics.
Page views and impressions are two commonly used words in the field of web analytics. These words are used interchangeably sometimes to denote the number of visits to a particular website. The term impression has a particular meaning however in context to page impressions; it is used as the same as page views. Generally, Impression is used in context to advertisement impressions.
Blogspot stats,JetPack Stats, StatCounter and any other stats you are using which are not analystic from google are not unique views. It count your own visits as well as visit from bots. You should create a Google Analytics account to get more accurate figures
A page view are unique visitors to webste, this is what Google counts in your reports every time a user views a page displaying Google ads. Adsense will count one page view regardless of the number of ads displayed on that page. For example, if you have a page displaying three ad units and it is viewed twice, you will generate two page views.
Pageviews are tallied for each page of your site. Web analytics programs calculate the average number of pageviews per visitor by dividing the total number of views by the number of unique visitors. This number gives you a sense of how many pages each person looks at when he comes to your site.
Both pageviews and impressions give a sense of your website’s success. A low pageview count can indicate a problem of poor website design, a need for calls to action, confusing content, or poor search engine optimization. They can also help you measure the effectiveness of a marketing campaign or promotion designed to bring people to a certain page on your website.
An increase in pageviews after the campaign launch can indicate that people have seen your marketing materials. When you combine pageviews with other analytics together,
An ad impression is reported whenever an individual ad has begun to download to the user’s device. Different ad formats will display varying numbers of ads; for example, each time a vertical banner appears on your site, you’ll see two ad impressions in your reports.
Impressions are often used to calculate how much an advertiser pays to display his message on a website. Each time a person loads a page and the ad pops up, it counts as one impression. If the website owner is using an ad program that pulls up random ads, the impressions for individual advertisers is lower than for static ads. Impressions are often calculated in sets of 1,000.
keep in mind that the number of ads in any ad unit may vary depending on whether the ad unit is displaying standard text ads expanded text ads, or display ads.
Discrepancies between Pageviews and Ad impression
1 Stats programs that get their data from the website’s log files will count “non-viewed” traffic, visits from spiders or bots. AdSense only counts a visit if the page is actually viewed in a browser.
3 You might have configured your stats program not to count impressions from your own IP address. These impressions will still be counted by AdSense.
4 AdSense won’t count page views when no ads actually appear on the page. If there are no ads available that match your content in a particular visitor’s country or region, then the visitor won’t see any ads and the impression won’t be counted by AdSense.
5 If visitor’s browser doesn’t support iframes (virtually all modern browsers do), AdSense won’t count the impression.
Below are how pageviews and ad impressions are calculated differently: Let’s say a blog has a banner ad placed above its header on all pages. A visitor opens the home page and sees the ad. So far, the blog has received one pageview, and the ad has received one impression. The user clicks through to another page, where the same ad is above the header. Now the blog has received two pageviews, and the ad has also received two impressions.
