ALT is an attribute, not a tag. Also…

Regarding the following message in the feedback tab:

The images on this page do not have alt tags containing your keyword / phrase.

Alt is technically an attribute of the IMG tag.

Also, the purpose of the alt attribute is technically to provide accessibility compliance for screen readers for people who have visual impairments. The content of the attribute should describe what the media contains, i.e. “a photo of a pine tree”. Not all images can, or should be described using keywords relating to the post.

For example, I have composed a post about an education summit. The photo used to draw interest to the post is of some students using a mobile device in the classroom. We want this post to not be self-serving, but more topical, so the imagery has to be a step removed from direct promotion. So, the image is definitely relevant to the spirit and theme of the content, but cannot be described in terms of the focus keyword.

What can we do to make the WP SEO plugin “give credit” for alt having a description, even if it’s not including the exact focus keyword.

Thanks.
