Unless I am overlooking something, there is currently no way to serve native/responsive ads from Google Ad Manager. The only options are for fixed sizes.
The line in the Google Publisher Tag looks like this for native/responsive only:
I know I could manually put the full tags wherever I want with theme components, but then I wouldn’t get any of the other plugin features like no ads for certain groups, etc. I would be hugely appreciative if this size option could be added to the plugin.
I’m not using AdSense at all so that doesn’t help me. I show custom native ads and ads from a different network, which are all served through DFP. The size code for these in DFP is ‘fluid’, but this isn’t currently an option in the ad plugin.
The only way I can get them to display is to assign them an incorrect fixed size in DFP and then override the CSS in a custom theme. This does work in limited cases, but it’s an ugly hack and not very scalable.
When I tried to add responsive ad sizes to DFP in 2017, there was no “fluid” option. I’ll have to look at how it works, and keep in mind that AdSense responsive ads changed recently.
Is there a reason for the plugin to be setting sizes at all? I noticed in the other topic you said that if multiple sizes are set it rotates through them evenly. This explains another problem I’ve had and is behavior I don’t want. If I have 10 ads in size ‘A’ and 1 in size ‘B’, I don’t want those sizes to have equal representation.
I already have very granular control over everything in Ad Manager, so I really don’t need or want the plugin to do anything more than display the ad units from the tags I generate. Is there a way to do this and just display it in an empty, unsized div?
