Common questions
What is image alt text?
A short description read by screen readers and used by search engines to understand image content.
Is the image alt text checker free?
Yes. Check any public page with no account and nothing to install.
How does alt text help seo?
It makes images eligible for image search and adds topical context crawlers can read.
What makes good alt text?
A short, specific description of what the image shows — not keyword lists or the file name.
Do decorative images need alt text?
They should carry empty alt text so screen readers skip them instead of reading file names aloud.
