On April 1st Google has conducted Adsense Webinar, for which I signed up, but due to some some personal problem I didn’t joined it. They were able to accommodate only first 500 publishers and luckily I was one of them.
This was 1hour session in which the Adsense’s Optimization Team members were demonstrating the ways that how can we make more with Adsense using few optimization techniques.
Day before Yesterday, I got an email from Adsense Team in which they shared a video link which is the recording of the one hour session.
Here is the video of the one hour session.
Also they shared few FAQ’s during the session.
Does adding additional ad units to your pages decrease CPC or eCPM?
Usually, most publishers see overall revenue gains if they place more ad units on their pages. Publishers may see a decrease in the average "eCPM" in their account, but this is expected because the additional ads on a page will usually generate lower per-click revenue. For example, the top 4 ads on a page will generate the most revenue through our auction model, and the next 5-8 ads will generate lower amounts. However, the overall revenue generated will usually be higher for the publisher.
Why are there large revenue fluctuations?
Many factors affect earnings including ad format, ad placement, user behavior and advertiser spending behavior. We recommend checking out our two-part blog post series on diagnosing revenue fluctuations to help troubleshoot your own issue.
I am doing everything right, but still earning low revenue. What else can I do?
Growing your user base is key to improving your revenue. Use analytics to better understand where your users are coming from and what content is most popular to cater to your users’ needs.
What is the performance difference between the 300×250 and the 336×280 units?
The 336×280 usually has a higher CTR; however we tend to have a higher image inventory for the 300×250 unit. Ultimately, both the large and medium rectangles are two of our top performing ad units, so using the one which fits most seamlessly into your site design is key.
Also they warned me that, from next time the publisher who will attend the webinar will get this notification. So it’s better to attend the session from the next time.
