Is it possible to ad a YouTube video to an ad?
Do you mean to the listing?
There is some ‘support’ for youtube videos in the theme – simply create a customfiled ‘youtube’ (it has to be all lowercase or else it will not work) – then add that custom field [youtube] in your listing layout. Once your customers fill the field with the youtube link, it should be replaced by video on their listing page.
If you find the videos limited (e.g. not responsive), if you want to show more than one video or you want to have more control, you could try the Embed Youtube plugin from Premiumwebservices.co.uk (https://premiumwebservices.co.uk/shop/responsive-themes-plugins/embed-youtube-responsive-pp-themes/ )
