What is Alt Text?
A short written description of an image that search engines and screen readers rely on.
In everyday terms
Like describing a photo over the phone to someone who can't see it.
A little more detail
Google can't 'see' pictures — it reads the alt text. Good alt text helps you show up in image search and makes your site usable for visitors with screen readers (which accessibility laws increasingly require). Our free Image Alt Checker finds images missing it.
