Hi guys, this is my first post in this forum and I’ve gone through quite a number of threads here for few days. I’ve pick up quick number of tips here. And currently I’ve some doubts that need your help. I’ve put a big square under the first post title and a skyscraper on the right zone of the blog. When I track the earnings using the channels, I found out that on average $0.08 per click from the big square and the skyscraper click is about $0.20. From my understanding reading threads from this forum, the highest paid Ad should be the on the big square rather than the skyscraper as the big square is the first Ad appear after the <body>. Could anyone explain this? Thanks.
Not necessarily...each ad impression has its value calculated in realtime based on a huge number of factors.
It also matters how the page is ultimately put together. Just because it's on the right side of the page doesn't necessarily mean the tower ad should display second.
dark0circles my understanding is the same as yours, and I'm pretty sure google have said the same thing - first code in the html code is highest paying. is your sample size large enough to be sure you are right? you won't be able to conclude much without 10s preferably hundreds of clicks presumably you aren't using CSS to 'switch around the code' and that your square really is first in the HTML?
The first ad block to load is not always the first ad block after the body tag. Without looking at the source of your page, it is hard to tell. However, tables can really change the order pages are loaded. Include files also don't always load in the same order as if the code were there (instead of included). You could use CSS to force the big block to load first, see if that changes anything.
It's not really the ad with the highest CPC that gets displayed first. It is the ad that will make the most over time, which is calculated with CTR * CPC. SO its possible that the ads in the first block are ones that have really good CTR. What you really should be looking at is eCPM, not CPC.
Very true. Google displays the ads in the order they think is most likely to earn you more money, not by the highest click value. Good catch.
druidelder: how can i use CSS to force the big block to load first? tlainevool:what should i look at eCPM? I just know that the higher the eCPM, the higher per click.
CPM calculates how much revenue you get per 1000 page views. It indicates which ad is bringing in more money. eCPM = CTR * CPC * 1000. This shows the real value of each ad block on your site.
There are just too many variables to tell what is a reasonable eCPM. It depends a lot on what niche you are in, what kind of traffic you have, how much you've been smart prices, and a whole bunch of other variable only Google knows about.
Here is a link that explains it well: http://www.sensecolumn.com/2006/03/first-ad-unit-contains-the-highest-paying-ads/#more-7 This is not my page. Essentially it boils down to using div tags to position the ads. You can put the div tags in any order and anywhere in the html code.
