Understanding your eCPM (effective cost per thousand impressions): Part 1 of 2

“What is eCPM? What affects my eCPM? What can I do to earn a higher eCPM?”

Effective cost per thousand impressions (eCPM) is the amount of revenue you can expect to earn from AdSense for every 1000 impressions shown on your site. Since eCPM helps you measure how well your ads are performing, we often hear questions from publishers about the factors that impact this metric and how it relates to their earnings. If you're using the new interface, you'll see that your reports show RPM (revenue per thousand impressions); RPM is just another term for eCPM, and it's calculated the same way, so we use these two terms interchangeably.

To help provide some clarity, we’re kicking off a two-part video series with more insights into how eCPM is calculated in order to help you maximize earnings. With the help of AdSense optimization specialist, Matthew Carpenter Arevalo, we’ll show you the factors that affect eCPM, how to track user behavior and traffic patterns, and what you can do to improve your website performance.

In the video below, Matthew will introduce you to the basics of how eCPM is calculated and explain how to analyze the causes behind any changes in your eCPM.

Stay tuned for Part 2 to learn what you can do to better understand and optimize your website’s eCPM.

New Interface Wednesdays: Compare and search performance across multiple date ranges

Have you ever run a test on one of your ad units, and wished you could more easily compare performance from before and after the test? If you've created and saved an ad unit in your account, you'll now find an easy way to do this in your ad units report.

• Start by visiting the Performance Reports tab and choosing the ad units report (you'll find it in the navigation bar under "Entire account by day").
• Search for the name of an ad unit you've updated and select it.
• Open the date range box and set a window of dates before your test -- for example, two weeks.
• Check the box marked "compare to other dates" and include a similar window of dates after you made the change to your ad unit.

In the graph, you'll then see the performance of your ad unit for both date ranges. You can still toggle the metrics shown on the graph using the radio buttons so you can compare CTR, RPM and other metrics that are relevant to you.


Try it now! Navigate to the new interface and click on the Performance Reports tab, and then ad unit report.

Display both text and image ads for an easy change with big impact

FunCheapSF.com is an online resource for finding free or affordable events in the San Francisco Bay Area. Founder Johnny Hayes recently shared his site’s story with us and gave some tips on an easy and high impact way that he’s optimized his revenue -- by enabling both text and image/rich media ads.

Inside AdSense: How did FunCheapSF.com come about?
Johnny Hayes: I moved to San Francisco without a job and couldn’t find much work, so I had a lot of time on my hands. I spent my time hunting down cheap and free things to do in the city and, starting in 2003, began emailing my friends with a weekly list of activities. More friends found out and wanted to be added to my email list, so I decided it was time to make a real website.

IA: How did you get started with AdSense?
JH: I began using AdSense in March 2007. It was my first source of online advertising revenue. As content developed on my site and traffic grew, my AdSense revenue grew as well.

IA: Why did you decide to opt in to both text and image/rich media ads?
JH: Several months ago, I received an email from AdSense letting me know that I hadn't opted in to displaying text ads and was only displaying image ads.

I had originally chosen to only show image ads because I figured they were more aesthetically appealing to my readers. But Google’s reasoning – which made sense to me – was that even though there’s tons of advertisers using image ads, there’s a bunch more out there who are specifically bidding on text ads. If I’m only showing image ads then I’m leaving the text advertisers out of the auction. And since these text ads would only be shown on my site if they outbid image ads, why not offer this space to them?

So I decided to give the text ads a shot. It seemed like an easy thing to do that might have a positive impact on my revenue with virtually no downside.

IA: What were the results? Would you recommend this strategy to other publishers?
JH: After enabling both text and image ads on my site, I saw a 51% revenue increase and nearly a 60% increase in average eCPM. It was an easy change with a big impact. And using AdSense means I don't have to worry about the laborious task of finding and managing advertisers myself and can instead focus my time on what I like to do – writing good content, putting together a great site and growing my business. I just plugged in the AdSense code and rarely have to think about it again.

I would say to other publishers that it’s worth giving the option for both text and image ads a try. It's pretty easy to set up – I just followed the instructions in the email I had received from AdSense and it took just a few minutes. Also, set up channels to track your ads so you can see specifically which of your ad locations and ad types are monetizing well, and continue with that.

If you want to give text and image ads a try like Johnny, click here to upgrade your units now!

• Once you're signed in to your AdSense account, click the "My Ads" tab in the new AdSense interface
