What alt text is for

It describes the image to someone who cannot see it. Every SEO benefit follows from doing that honestly — it is not a keyword slot.

Missing alt is a bug. A screen reader falls back to reading the filename, which is usually meaningless.
Empty alt="" is correct for decorative images — it tells assistive tech to skip them. Missing and empty are not the same thing.
Around 125 characters is where most screen readers start truncating. Be specific, not exhaustive.
Do not start with "image of". The screen reader already announced it is an image.

Accessibility and alt text are worth doing. Neither one builds authority.
