Proper alt text also helps people who are blind or who have low vision understand your images there by improving the accessibility of your website. This will open up your website to a new segment of visitors and increase your traffic.

<li>Set the image filename as the image Alt Text. This was a default feature in WordPress before 4.7. The plugin restores this essential feature which is great for SEO.</li>

Auto Image Attributes From Filename With Bulk Updater (Add Alt Text, Image Title For Image SEO)


the title says it. This plugin will overwrite existing Alt Text values. This is bad if you've already added any Alt Text values yourself in the past, those will be lost and overwritten with the file name... probably with a non human friendly file name.



If they update this later to check for existing values and don't overwrite those then I would recommend giving it another try.



PS: this goes for ALL title, alt text, description, and caption. All of these will be overwritten even if you already have it set to something.


Will overwrite existing Alt Text

Automatically add Image Alt Text, Title, Caption and Description from Filename. Bulk update existing images. Great for Image SEO and Accessibility.
