Frequently Asked Questions
Why is alt text important for SEO?
Image alt text helps search engine crawlers (like Googlebot) understand the subject matter of an image, which improves your chances of ranking in Google Images. It also adds topical relevance to the webpage surrounding it.
What's the difference between Alt Text and an image caption?
An image caption provides extra context for readers who can see the image (e.g., "The CEO giving a speech in 2024"). Alt text describes the visual contents of the image for people who cannot see it (e.g., "A man in a blue suit standing at a podium holding a microphone").
Does your AI consider WCAG and screen readers?
Yes! If you select the "Descriptive WCAG" mode, the image alt text generator focuses entirely on accessibility. It skips robotic introductions like "A picture of..." and immediately provides a vivid, sensory description of the scene so visually impaired users get the full context.
Are 125 characters really the limit for alt text?
Most screen readers stop reading alt text after 125 characters. For general SEO and standard web images, you should use our Concise mode to stay under the limit. If the image is highly complex (like a chart or infographic), use the Descriptive mode.
How do I put my own SEO keywords into the generated text?
Just type your target keywords into the "SEO Keywords" box. Our describe image for SEO engine will intelligently weave them into the natural description without making it sound "keyword stuffed."
