How can check missing alt tags?

[smurugappan01]

One incredibly simple but effective thing you can do to improve your SEO rankings is to put keywords in your Alt tags. The Alt tag (also called Alt text) is a line of text which describes the image. It is what will show up if your image cannot render for some reason. Why wouldn’t your image render? It might be a browser problem. It could be that the user has images disabled. Or maybe the user is vision impaired and uses a screen reader. In any case, putting in Alt Tags ensures that the message you want to convey with the image gets across, regardless of whether the image is seen. In WordPress you can put the Alt text in when adding photos.
