Understanding your reports on Google-certified ad networks

Since launching a new report to show you how much you’re earning from Google-certified third party ad networks, we’ve received questions from publishers around how to make sense of the numbers they’re seeing. Some have let us know that they’re now blocking lower-performing ad networks based on revenue per thousand impressions (RPMs), a practice which can actually have a negative impact on overall revenue. Today, we’d like to take a moment to address your questions and provide more guidance around understanding your reports and blocking specific ad networks.

Let’s first talk about analyzing RPM figures. If you’ve ever tested color combinations for your ad units using channels, you’re probably used to comparing the RPMs of each channel to determine which one is most effective. Then, once you find the most effective combination, you remove all the other options and only use the optimal one. This works for channels, but it’s important to keep in mind that with Google-certified ad networks, the same approach doesn’t apply.

It’s true that in both situations, RPM represents the estimated earnings you'd accrue for every thousand impressions you receive. However, when you test layout options with channels and remove the ones that don’t perform well, this action doesn’t directly impact the dynamics of the ad auction. Picking a blue background over green won’t automatically remove certain ads from being eligible to appear in that ad space -- it just helps certain ad spaces perform better. With Google-certified ad networks, RPMs are dependent on the available ad inventory. Blocking an ad network will remove eligible ads from the auction, and so we strongly recommend against blocking ad networks solely based on RPM. Let’s look at an example:

Ad networks	Impressions	RPM
Network A	10,000	$1
Network B	14	$3
Network C	1000	$0.50

Network B has the highest RPM and appears to be outperforming the other networks. It’s important to note though that this metric is based on only 14 impressions and might not reflect the same revenue for the next 1000 or 10,000 impressions. The value of impressions can vary widely, so the RPM for a small number of impressions can be misleading.

Network C has the lowest RPM. However, blocking Network C because of this might have a negative impact on revenue. This is because our system will always maximize the value of every impression in an auction -- if an ad from Network C appeared on your pages, it was because any other eligible ads that could have appeared would have generated less revenue for you. By Blocking Network C, another network with a lower-paying bid might win the ad auction instead.

In general, blocking reduces the number of ads participating in the ad auction, which can then have a negative impact on your potential revenue. Please keep in mind that blocking “low paying ads” is a myth, as any ad that appears on your page has won the auction for that space and will earn you the most possible.

At the same time, we also understand that you sometimes need to prevent ads from appearing due to the content of the ad or advertiser. You have several options in your account, which are suitable for different scenarios.

With your feedback in mind, we’re constantly working on offering you more control over the ads appearing on your sites, so watch this space for further announcements! However, don’t forget to carefully consider which ads you’re blocking to ensure that you reach your full revenue potential.

Taking your channels to a new limit

As you know, channels in your AdSense account are powerful reporting tools. Custom channels help you track ad performance and enable advertisers to target their ads for maximum impact, while URL channels allow you to deep-dive into the performance of AdSense for content on your subdomains.

To date, you’ve been limited to a total of 200 custom and URL channels, and many of you have asked for more. That’s why today, we’re very excited to announce that we’ve raised this limit to 500 custom channels per product, and 500 URL channels for AdSense for content. You’ll see your available custom channels count clearly displayed in the custom channels table, and also highlighted in the “create new custom channel” pop-up.

This change will enable you to expand your testing, and you’ll be able to do more granular analysis of how different formats, ad styles, and ad types perform. In addition, you can use your increased allocation of custom channels to create new ad placements for advertisers to target directly. This can help increase the amount you earn from placement targeting, as advertisers will be able to review the information you’ve provided about your ad units to match their campaigns to your site and audience. As the holidays approach and advertisers look to create additional placement targeted campaigns, now is the perfect time to set up more custom channels and ad placements.

Understanding eCPM and RPM

Recently, we’ve heard some questions about the difference between eCPM (effective cost per thousand impressions) and RPM (revenue per thousand impressions), as the older AdSense interface references eCPM and the newer version shows RPM. We’d like to clarify and let you know that the terms are referring to the same thing: both eCPM and RPM represent your estimated earnings for every 1000 impressions. To calculate this figure, divide your estimated earnings by the number of page views, impressions or queries that you received, then multiply by 1000. For example, if you earned an estimated $0.20 from 50 page views, then your page eCPM or RPM would equal ($0.20 / 50) * 1000 or $4.00.

Formula:
eCPM or RPM = (Estimated earnings / Number of page views) * 1000

To avoid confusion in the future, we’ll work to use only one term (RPM). RPM is a commonly used metric in advertising programs, and you may find it helpful for comparing revenue across different channels. You can learn a lot more about using RPM in our two part blog series (part 1 and part 2).

You’ll be able to see a breakdown of your earnings based on where your traffic is coming from, which you can use to then optimize your site and give users a better experience. For instance, if you find that you’re receiving a high percentage of traffic from mobile devices, we’d encourage you to create a mobile version of your website and monetize it with AdSense for mobile content.

With this feature, you’ll be able to see your performance data broken out into these categories:

- Desktop - all traffic coming from desktop users
- High-end mobile devices - includes smartphone devices
- Other mobile devices - includes low end and mid-range phones

Try out this new report by navigating to the new interface and clicking on the Performance reports tab. Choose Platforms in the left navigation.


And as a quick reminder, we’re gradually moving away from the older version as we continue to focus on reporting improvements like these.

New Interface Wednesdays: Analyzing earnings by page views vs. ad requests

If you’ve spent time wandering around the Performance reports tab in the new interface, you've likely stumbled upon the Columns button. This button lets you customize your report to view earnings by page views, ad requests, matched requests and individual ad impressions. Selecting one of these options will change the columns and data shown in the table and graph. All other metrics, like CTR & RPM, will be based on the selection you choose.

We’ve received some questions about understanding these reports, especially when viewing by ‘page views’ and ‘ad requests’. To get an overall sense of your ad performance, view your earnings by ‘page views’. When looking at specific ad units or channels, however, we recommend using the ‘ad requests’ view. This will provide you the most accurate numbers for specific reports like ad units, ad sizes, custom channels, ad types, targeting types, and bid types.

Why is this? When analyzing the performance of individual ad units, the ‘page views’ view may show you inaccurate CTRs and RPMs if you have multiple ad units on one page. Each time a user views a page with multiple ad units, your reports will log only one page view and associate it with the first ad unit on the page. This means that when you’re viewing more granular reports by ‘page views’, the CTR and RPM of the second and third ad units on the page will be calculated based on “zero” page views, resulting in invalid data. By using the ‘ad request’ view when looking at specific ad units, you’ll ensure that you’re reviewing valid CTR and RPM values.

Try it now! Navigate to the new interface and click on the Performance reports tab, then select the ‘Columns’ button from any report to change the metrics you’re viewing.

Today marks the last post of our New Interface Wednesday series. We hope you're now more familiar with features available in the new interface, and how you can use them to better understand your ad performance and manage your account. You can review any of the previous posts in this series by visiting the New AdSense Interface label at any time, and learn more about specific features in our Help Center. As we continue to develop new features in the new interface, we'll be sure to post updates here on our blog, so please check back frequently!

New Interface Wednesdays: Multi-dimension reporting

We've been listening to your feedback for more reporting and better insights into your data and are pleased to share a powerful new feature called multi-dimension reporting. You can now add dimensions to your performance reports to sort and view data across multiple dimensions including ad units, ad sizes, and countries.

This new feature allows you to add up to three dimensions to your reports, including viewing a channel by date or an ad unit by targeting type. To add a dimension when you create or edit a report, click ‘Add dimension’ and select a dimension. The dimension selected is added to the table, so you will now see two dimensions. To add another dimension click ‘Add dimension’ and select again. You can also change and remove a dimension by clicking the drop-down for the dimension you want to change or remove.

Try multi-dimension reporting now to interactively explore your data and gain more performance insights. And stay tuned for more dimension combinations coming soon as we continue to improve reporting regularly.

This reporting capability is just one of many improvements we’re making to the new AdSense interface as we gradually move away from the older version. Please feel free to provide your feedback in the comments field below so we can continue to tailor the new interface to your needs! If you haven’t yet tried the new interface, learn more about getting started today.

New Interface Wednesdays: Chart custom channels

We understand that many of you analyze how ad units or channels perform compared to each other to help you decide whether you should make changes to improve performance. Now, in the new interface, we provide you a new way to analyze individual items against one another.

The chart feature will allow you to see custom channels or ad units as their own line on the graph, so you can easily identify spikes or dips. To see how your channels perform compared to each other, visit the Performance Reports tab, and click Custom channels. Depending on the number of channels you’re using, you might be asked to filter the list and then click Update report. Once your selected channels are listed below the graph, you'll see the Combine and Chart buttons.

Select a few channels and hit ‘Chart.’ Now you can see each specific channel in it’s own color on the graph. You can use the buttons next to the graph to change the metric for which you’re comparing the channels. Using this feature, you might notice that discrepancies between channel performance are more obvious on the graph than they are just viewing the numbers in the table.


Try it now! Navigate to the Performance reports tab, and select any report for which you want to chart items.

Help us figure out what you need and want in your reports by sending your feedback through the ‘Report issue’ link in the upper corner of your account or joining the conversations in our forum.
