Alt attribute optimization used to be a huge factor for SEO years ago. The main purpose for alt text is accessibility. Many of us are guilty of adding images to our websites without proper alt text. These plugins can help you fix that issue:

BIALTY: this plugin automatically adds alt texts to your images from your titles. It also supports manual customization.
Image Attributes Pro: this plugin automatically adds title, caption, description and alt text to your images. It can update old images in your library too. You can use this plugin to set image filenames as title, alt text and clean them up.
Automatic Alternative Text: another plugin that makes your images accessible by generating alt text for them using Microsoft’s Cognitive Services Computer Vision API.
