Hello, sometimes on my site I see that the links are displayed but without any notice from Google that that links are Google Ads, see here: how is that possible ? Thanks.
Google often tries different formats; it might be testing this one as well. Nothing to be worried about.
it happens when you change or add a new ad on your page and it follows sometimes the format of the ad that u changed...try going to another site...then going back...it will be fine then...
