Frequently Asked Questions About Alt Text

What is alt text and why is it important?

Alt text (alternative text) is a description of an image that appears in the HTML alt attribute. It's crucial for web accessibility as it allows screen readers to describe images to visually impaired users. Alt text also helps with SEO by providing context to search engines about image content.

How long should alt text be?

Alt text should typically be between 5-125 characters. Keep it concise but descriptive enough to convey the image's meaning and context. Screen readers may cut off longer descriptions, and search engines prefer shorter, more focused alt text for SEO purposes.

What makes good alt text?

Good alt text is descriptive, concise, and contextually relevant. It should describe what's in the image without starting with 'Image of' or 'Picture of'. Include important details that convey the image's purpose and meaning within the content context.

Should decorative images have alt text?

Decorative images that don't add meaningful content should have empty alt attributes (alt="") to indicate they're decorative. This tells screen readers to skip them. However, if an image serves a purpose or conveys information, it should have descriptive alt text.

How does alt text affect SEO?

Alt text helps search engines understand image content, which can improve image search rankings and overall SEO. Well-written alt text with relevant keywords can help images appear in Google Image search results and provide additional context for page content.
