I have put an image that I created in Canva into the SEO & Analytics tab for my landing page. It is clear and crisp in Canva, but it is not clear and crisp image (grainy) when I link my landing page on facebook (or elsewhere). I saw guidance elsewhere to size these to 500x261 for FB which I did. I also tried larger thinking perhaps that would help the quality, but it did not help. Suggestions? I just think it makes the offer look low-quality when the image isn't sharp. #ConvertKitHelpForum
