AdSense Custom Ad Size Opens Unlimited Placement Opportunities

In past one year, AdSense surprised me with the number of changes they have introduced. Starting from Responsive ad unit, adding AdSense A/bTesting and now custom ad sizes is clear reflection of AdSense turning into a publisher oriented company. According to rumours, they are also adding EFT payment option for Indian AdSense publishers, but for now let’s talk about newly introduced AdSense Custom ad Sizes.

Earlier, AdSense have fixed ad size unit which you can create and embed on your blog. Most of these ad sizes are of web-standards and have more fill-rates in comparison to other ad unit size. Later on AdSense added some bigger ad unit size and they used to club 2 or smaller ad units to fill the ad space. Now, to give more power to publishers, AdSense launched 99,999+ ad unit sizes or you can say custom ad unit size, which will let you create ad unit of any size you need. I will share all the details below, but first lets see how you can create custom size AdSense unit.

How to Create Custom Size AdSense Ad unit?

Like you create a normal AdSense Ad unit, you will be following the same process. Under Ad Size tab, you will be selecting custom ad size and adding the height and width of the ad unit which you want to create. Below is an image for better understanding:

Under ad Type, you can select from Text and display ads, or text only or display ads only depending upon the custom size you are creating. For example, if you create a wide AdSense ad size such as 500*500 ad size, you can expect it to get filled by 2 (250*250) standard ad unit. When you create a custom ad unit, it will take some time for AdSense to determine which ad type will perform better there, and you might notice a slight decrease in earning initially. But, if you have created an ad unit which blends smartly with your content, you are more likely to earn way more once AdSense will start filling the ad unit with proper ad.

It’s a good idea to start with Text only ads as they have more fill rate. According to me, it would be best to choose between Text or display ads, depending upon the size of custom ad unit you are creating. For example, I would prefer to create 728*30 custom ad size with text ads only, because it can easily be filled with 2 (728*15) text ad unit size. Below is an example of custom ad unit showing AdSense text ads:

Similarly AdSense will show display ads (Image only ads) for your custom size, as shown in below image. Do note: Dotted line in below image is just for representation, and on live site unfilled area will be shown as blank. So you might like to place it accordingly when you select to show image only ads.

Here are some restrictions when you are creating custom Ad size AdSense units:

• Only one dimension can be greater than 300 pixels
• The minimum width is 120 pixels
• The minimum height is 50 pixels
• Neither height nor width can exceed 1200 pixels.

With AdSense custom ad unit, AdSense have given some of the feature of premium AdSense publisher to normal AdSense publisher, but do note that we still have limitations on number of Ad units we can display on our blog.  For now, go ahead and take advantage of custom ad unit size to make your web-page look better and improve your earning.
