@optimizingmatters thanks for your reply.
* you have microdata on, I presume?
yes
* do you have a working YT API key?
I do have the Api key in there, but when I test the key, it gives me:
Checking your key …
Der API Schlüssel dürfte gültig sein, aber der API Aufruf war nicht erfolgreich oder die Rückmeldung war nicht ganz erwartet. Technischer Fehler.accessNotConfigured
So till now I assumed it would work, but could it be something with this key and if so what could it be?
* when looking at the HTML source, do you indeed see those are missing or not?
Yes, it looks to me like they are missing.
Hope to hear from you.
Kind regards,
Coen
Thanks @shirtguy72 for putting in this question and @optimizingmatters for looking at it so quickly.
I also saw it coming up this morning in Search console and see that by all the video’s it shows me the following in Search console:
Missing field ‘name’
Missing field ‘description’
Missing field ‘uploadDate’
I also checked it with the testing tool for microdata from Google and there it gives these three fields as red. Hope this contributes.
