Ezoic Customer Service -

*Note: if you use WordPress, we recommend logging out of your WordPress Admin when using the Ad Tester Chrome Extension to ensure best functionality.

The Ad Tester extension allows you to choose the locations and sizes of ads on your site without having to replace any code on your page. 

To use the Ad Tester extension please download the extension from the Chrome store here. Once it's installed, the little green Ezoic icon will show up in your browser. 

Watch the video version of the extension demo below:


To use the extension, go to the page on your site where want to add placeholders. 

Once on the page, click on the Ezoic icon and hit Activate Placeholders. If you already have existing placeholders on the page they'll appear and you can toggle between the different sizes or choose to only show indicators. To make a new placeholder hit Create, select a Placeholder Size, and click Select Location. 


To use the Ad Tester extension to create new placeholders follow these easy steps: 

STEP ONE: Choose the create button to get started. We suggest using 'Automatically Detect' as the placeholder size. This allows the system to gauge how big an ad can fit in that size and select all ad sizes that apply. Then click select location. 

STEP TWO: Use your mouse to hover over an area where you would like the system to test an ad. The selection will highlight in blue. 

STEP THREE: Click on the box and choose if you want the ad at the beginning of the end of the element using the arrows. 

STEP FOUR: When you've chosen the correct place for the ad click 'Insert Here'.


Chrome Placeholders Settings

Once a placeholder is inserted, you will be prompted to select a page position and devices you would like the placeholder to appear. 

The Size Tab allows you to select which ad-sizes each placeholders will test. You can select or deselect any sizes listed. All sizes that can fit in that location will automatically be selected. 

For more information on Ezoic placeholders. you can check out the Placeholders Guide.


The Page Tab allows you to choose what pages the placeholder will appear on. By default, the Ezoic system will find similar pages and put the placeholders on them, however you can also choose to put the placeholders on one page, or one directory. 

The Style tab allows you to style the placeholders. You can choose the size of the margin in the top section.

The Float Section gives you the option of left or right alignment for the ads when test is wrapped around the ad. 

The Alignment Section allows you to put the placeholder on its own row and choose the alignment. 

You can also add native and link unit placeholders by scrolling down in the
chrome extension where it initially says "automatically detect." Adding them
works the same was as display placeholders.


To View the placeholders on your site choose 'view' in the Ad Tester extension. 

This will make all the ad placeholders show in various colors (there's a different color for each position type) and include a drop down of all the sizes selected. If you click on "edit" the editor window will reappear and you can make any changes to the sizes, styles, and position selection.

You can also delete the unit completely from here by clicking 'remove'.
