Frequently Asked Questions
Q: What is alt text and why is it important?
A: Alt text (alternative text) is a written description of an image that appears when the image fails to load and is read aloud by screen readers for visually impaired users. It’s crucial for web accessibility, SEO ranking, and user experience.
Q: How long should alt text be?
A: Ideally, alt text should be under 125 characters. It should be descriptive but concise enough to be easily understood by screen readers and search engines.
Q: When should I use empty alt text (alt=””)?
A: Use empty alt text for decorative images that don’t convey important information, such as background images, spacing images, or purely decorative elements.
Q: Is this AI Alt Text Generator completely free?
A: Yes! Our tool is 100% free to use. You don’t need to create an account, and there are no hidden fees or usage limits.
Q: What image formats does the tool support?
A: Our tool supports all common image formats including JPG, JPEG, PNG, WebP, and GIF files.
Q: How accurate is the AI-generated alt text?
A: The AI is trained on millions of images and provides highly accurate descriptions. However, we recommend reviewing the generated text to ensure it matches your specific context and needs.
Q: How does alt text affect SEO?
A: Alt text helps search engines understand your images, which can improve your image search rankings and overall page SEO. It also provides additional context about your content.
Q: Should I include keywords in my alt text?
A: Yes, but naturally. Include relevant keywords that describe the image accurately, but avoid keyword stuffing. The primary goal should always be accurate description.
Q: What’s the difference between alt text and image title?
A: Alt text is for accessibility and SEO, while image titles appear as tooltips when users hover over images. Both are important, but alt text is more critical for SEO and accessibility.
Q: Where do I add alt text in WordPress?
A: In WordPress, you can add alt text in the “Alt Text” field when uploading or editing an image in the Media Library, or directly in the Image Block settings.
Q: Do I need to add alt text to every image on my website?
A: Yes, every meaningful image should have alt text. Decorative images should have empty alt text (alt=””) to indicate they can be ignored by screen readers.
Q: How do I check if my website images have proper alt text?
A: You can use browser extensions, SEO tools like SEMrush or Ahrefs, or accessibility checkers to audit your website’s alt text.
Q: What makes good alt text?
A: Good alt text is accurate, concise, and descriptive. It should convey the same information and function as the image would to a sighted user.
Q: Should I start alt text with “Image of” or “Picture of”?
A: No, screen readers already announce that it’s an image. Start with the actual description to avoid redundancy.
Q: How specific should I be with alt text?
A: Be as specific as necessary to convey the image’s purpose. For example, instead of “dog,” use “golden retriever playing in park” if that detail is relevant.
Q: What should I do for complex images like infographics?
A: For complex images, provide a brief summary in the alt text and then offer a more detailed description elsewhere on the page or through a link.
Q: How often should I update my image alt text?
A: Review and update alt text whenever you update your website content, change your SEO strategy, or receive feedback about accessibility issues.
