Google’s John Mueller said this morning on Twitter that if you want your images to rank in Google Image search, it is extremely helpful to Google if you add alt text to your images. The advice itself is not new, it dates back over 10 years ago but this is a nice reminder from a Googler.

Like I said, this is not new advice but the way John wrote it, it sounds a lot more important than other times. We covered the importance of alt text back in 2017, 2018, and tens years before that, plus many other times. Back in May, Google even updated their image SEO guidelines which talks about the importance of alt text.
