Measuring and optimising Google AdSense campaigns
Once you have AdSense set up on your site, the service has a number of tools to help you measure how effective the ad campaigns earning revenue for your site are performing and insights into how to make them perform better.
Understanding advertisers, ad auctions and types of ads
First, it is important to understand how an ad gets selected for display on your website and how much the advertiser will pay. Usually this is done through the real-timeReal-timeEvents that happen “live” at a particular moment. When one chats in a chat…//read more ad auction, which automatically matches advertisers who have signed up to place their ads with Google AdWords with websites looking to hostHostAny computer on a network that offers services or connectivity to other…//read more advertisements through Google AdSense. The ad auction consists of a pool of relevant ads that are bidding for your space, and based on their bid and their likely performance one ad will win.
To determine who wins the auction, Google assigns a quality score for each ad based on a few factors including the ad’s past performance. Google creates an AdRank which takes into account the quality score and the maximum CPCCPC (Cost-per-Click)CPC or cost-per-click is the cost of advertising based on the number of clicks…//read more (cost per clickClickA click can denote several different things.

The advertiser with the highest AdRank wins that spot on your site, but what they pay is based on their quality score, and the AdRank of the other bidders. This rate, which is not necessarily their maximum bid, is therefore heavily impacted by the amount of bidders in the auction pool.

Advertisers who are part of AdWords also choose one of three types of ways that they want to target their ads:

- Placement targeting (or managed placements) is when the advertiser hand-picks websites they want to advertise on.
- Interest-based advertising is when ads are shown to specific audiences based on the advertiser choosing from 1,600 interest categories, and matching them to a specific audience based on a combination of your website’s keywords and the users’ cookies (small files that contain information on other sites they tend to visitVisitA single continous set of activity attributable to a cookied browser or user…//read more , demographic information they may have entered on other websites or social networks, etc.)
To get an overview of how well your ads are performing, click on the Performance Reports tab in your AdSense interface. Here you can see your estimated earnings, page viewsPage ViewsWhen the page is actually seen by the user. Some platforms, like Facebook cache…//read more , clicks, PCR (pagePageA document having a specific URL and comprised of a set of associated files.

You can also compare two date ranges. This can be useful if you made a change to your ads or site layout and want to see how that might have impacted the performance of your ads.
One thing to note is that currently all the AdSense reports are based on the United States Pacific Time (PT) time zone and a day is considered to start at 12:00 am PT and end at 11:59 pm PT. There is no option as of yet to change this.
Measuring performance: Reports
Under the Performance Report tab, the left sidebar provides you with a variety of report types.
- Ad units – displays performance reports based on an ad unit (an individual or a set of ads displayed based on the results of one piece of AdSense code repeated in different spaces on your website).
- Ad sizes – displays performance reports based on the different ad sizes you have used on your site.
- Ad types – displays performance reports based on the different types of ads ultimately displayed, including images, text, rich mediaRich mediaAdvertisements with which users can interact (as opposed to solely animation)…//read more , flash, etc. This is especially useful if you have allowed all ad types, and want to see if some do better than others.
- Targeting types – displays performance reports based on contextual targeting, placement targeting, and interest-based advertising.
- Bid types – displays performance reports based on ads that are paid by CPC (cost per click) or by CPMCPM (Cost per mille)Online advertising can be purchased on the basis of what it costs to show the…//read more (cost per thousand impressions).

Google has a comprehensive glossary for the terms that are used in its AdSense reports. In addition to the glossary, Google also has this 2-minute video that provides a step-by-step explanation of how to use advanced reports.
A custom channel is a group of ad units defined by you for reporting purposes. For example, you might create one custom channel for your homepage, and one for a section front and another for a layout that you are trying out at the top of a page.
When creating a custom channel, you can also check the option for “Show this custom channel to advertisers as a targetable ad placement”. This important option allows you to optimize placement targeted ads by creating a channel which groups ad placements by topic, ad format, or location on a page – all important distinctions for advertisers looking to buy a specific location or reachReach1) unique users that visited the site over the course of the reporting period,…//read more a particular audience. Once you check this option, you will be asked for more information:
- Ads appear on: Note where ads in this placement appear on your site – on the homepage, or on other types of pages.
- Ad location: Select the location on the page where ads in this placement appear. For example, you might make a placement featuring ads in the top right of your pages.
- Description: This is what an advertiser will probably use to decide whether to place the ad or not so be very specific. Even go so far as to suggest an audience type who will likely view these ads.
- Site language: The primary language of your site content.
These are custom channels for reporting on your ads based on the directory structure of your site. By entering a top-level domain nameDomain nameThe unique name that identifies an Internet site. Every domain name consists of…//read more or main web address of your site, you can track all the pages on that domain, or you can enter a partial URL, which would allow you to track ad performance on a particular section on your site.
If you are using Google Analytics for your website, you can also link your AdSense data with your Google Analytics account, which will give you even more information about who is clicking on your ads. For example, you can see the geographic region where they’re coming from, what referring site sent them to your site, and how long they stay on your page before clicking an ad.
To see your AdSense data, either click on the Content section in the Google Analytics navigation sidebar for your AdSense reports, or click the AdSense Revenue tab for a breakdown of your traffic by AdSense impressions, clicks and revenue in many other reports.
Optimising your ad performance
Linking AdSense to Google Analytics is just one way to measure the performance of your ads so that you evolve your strategy to get the highest possible returns from your ads. You’ll want to interpret your data and make small, informed changes to improve your advertising strategy. There are several different ways to optimise the performance of your ad network advertising. According to Google:
- Wider ad sizes tend to perform the best because of how much easier they are to read. AdSense suggests a few sizes that work best when you create your ad unit, but it is important to keep in mind your own website’s layout.
- Customise the colours of text, links and the ad background to integrate better with your site.
- In general, ads located above the scroll tend to perform better than those that require users to scroll to see.
- Ads placed near navigational aids and other engaging content also perform well due to high visibility.
Limiting ads through blocking
Of course, the best way to optimize the amount of money you get for ads is to allow as many advertisers as possible to enter the ad auction, simply and easily. However, you could have ads placed on your site that are offensive or ads for your competitors that you would want to block from advertising on your page. To block or limit ads, you can click the Allow & Block Ads tab to include specific URLs, topics, sensitive categories, or even specific ad networksAd networksAd networks provide an outsourced sales capability for publishers and a means…//read more .
You also do have the option, on your settings page, to hold all ads for a 24-hour review period before they show up on your site. However, the default is to run ads immediately which will maximize your potential revenue by opening up the competition to more ads.
Other Google ad services
Connect with high-quality advertisers

Warning: How not to increase revenue
AdSense has fairly strict policies against certain practices that would encourage fake click-throughs. A big one is masking ads – you cannot make it difficult to distinguish ads from your content. You also cannot use any language to encourage people to click on the ads, or place misleading labels above ad units such as “Favourite Sites” or “Today’s Top Offers”. Google advises to avoid partnering with untrusted or low-quality ad networks, search engines or directory sites in an effort to increase traffic. Lastly, there is a strict rule against clicking on your own ads – even if you’re interested in an ad or looking for its destination URL. Instead of clicking on the ad on your site, Google advises you to use a search engineSearch engineA website that provides a searchable index of online content, whereby users…//read more to find the URL for that company.
