Frequently Asked Questions about our AI Image Alt Text Generator
What is an image alt text?
Image alt text (short for "alternative text") is a brief description of an image that helps people understand what's in the image — even if they can't see it.
It appears in the website’s HTML and serves two important purposes:
- Accessibility: Screen readers use alt text to describe images to users who are visually impaired.
- SEO: Search engines read alt text to better understand your images and rank your pages more accurately in search results.
Good alt text makes your website more inclusive and helps your images appear in Google and AI-powered search experiences.
What are best practices for writing image alt text?
Be descriptive, but concise
Clearly describe the image without adding unnecessary details. Aim for one short, specific sentence.
Use keywords naturally
If relevant, include keywords — but only if they fit naturally. Don’t stuff keywords or force them.
Focus on the content and function
Describe the essential information or purpose of the image, especially for functional images like buttons or links.
Skip “image of” or “picture of”
Screen readers already announce it's an image, so just describe the content directly.
Leave decorative images empty
For purely decorative images that don't add meaning (like background flourishes), use empty alt text (alt="") so they don’t clutter the experience for screen reader users.
