Our take on the og:image:alt tag

 There’s some good intent in providing the og:image:alt tag, but it all depends on the image usage and context. Based on our testing, it appears the og:image:alt can be easily misused and lead to non-ideal results. We do believe it’s not something that users or an SEO plugin should attempt to manage. Instead, we do believe that not setting the og:image:alt tag is the best option. With Yoast SEO, we do provide the image, the post and metadata, and it’s up to social media platforms to present those in an accessible manner.
