Hey. On my site that uses CloudFlare, ads from google or youtube are not displayed. Videos that are made available on the site by embedding do not display ads when they are included on the site, but I care about it there. Is CloudFlare blocking it in some way? If so, how to unlock it?
No, unless you did something deliberately tricky with your Cloudflare setup.
Use your browser’s Dev Tools and check the Console log and Network tab for any blocked requests.
See https://support.google.com/youtube/answer/132596?hl=en. Are you certain you meet the requirements for embedded Youtube ads?
Also, can you see if any Google Ads (adsense) ads are being blocked? Or is it just YT ads?
