Open Graph image dimensions missing or below minimum

Open Graph (OG) is the standard that controls what preview image appears when someone shares your page on Facebook, LinkedIn, or messaging apps. Your OG image is either missing its declared size or is below the recommended minimum — Facebook and LinkedIn both recommend at least 1200 x 630 pixels and will crop or pixelate anything smaller. Social platforms pixelate or crop undersized images, making your shared links look unprofessional. A blurry or missing preview image gets far fewer clicks than a sharp, properly sized one. Set an og:image tag in your page's header that points to a high-quality image at least 1200 x 630 pixels. Declare the width and height alongside it so platforms know the dimensions without downloading the file first.
