Question 1

What is alt text?

Accepted Answer

Alt text is a written description added to an image's HTML `alt` attribute. It helps people understand meaningful images when they use a screen reader, when images fail to load, or when a browser cannot display the image. It also gives search engines useful context about what the image shows and how it relates to the surrounding page. Good alt text is not just a caption; it should describe the image's purpose in context.

Question 2

What is an alt text generator?

Accepted Answer

An alt text generator is a tool that creates draft alternative text from an image and optional page context. An AI alt text generator can help with product photos, blog images, screenshots, charts, icons, promotional banners, and accessibility review workflows. The best results come when you add context such as where the image appears, what the page is about, and whether the image is decorative, informational, functional, or product-focused.

Question 3

What makes good alt text?

Accepted Answer

Good alt text is specific, useful in context, natural to read, and focused on the image's purpose. It names the meaningful subject, action, product, visible text, or data takeaway without describing every tiny visual detail. For example, a product image may need color, material, shape, and key features, while a screenshot may only need the screen's purpose and main information.

Question 4

What is bad alt text?

Accepted Answer

Bad alt text is vague, stuffed with keywords, misleading, too long for a simple image, or full of details that do not matter. Examples include "image," "photo," "product," or repeated SEO phrases like "leather backpack best backpack travel backpack." Starting every description with "image of" is usually unnecessary because screen readers already announce that the element is an image.

Question 5

Does alt text help SEO?

Accepted Answer

Yes. Helpful alt text can give search engines more context about an image and the page it appears on, especially for product pages, blog posts, tutorials, ecommerce collections, and image-heavy content. It should still read naturally for people. Use a keyword only when it accurately describes the image or the page context; do not force keywords into every image.

Question 6

Can I use keywords in alt text?

Accepted Answer

Yes, but only when the keyword accurately describes the image or page context. A phrase like "brown leather backpack with brass buckles" can be useful when the image truly shows that product. A repeated list of keywords is not useful for accessibility and can make the page feel spammy. Write for the user first, then make sure the wording is relevant to search.

Question 7

Should every image have alt text?

Accepted Answer

Every meaningful image should have useful alt text, but not every image needs a spoken description. Decorative images should usually use an empty alt attribute, `alt=""`, so assistive technologies can skip them. Functional images, such as icon buttons, need alt text that describes the action, such as "Search" or "Close," rather than the icon shape.

Question 8

What should I do with decorative images?

Accepted Answer

If an image is purely decorative and adds no meaningful information, use `alt=""`. Do not describe background shapes, dividers, texture images, abstract accents, or visual flourishes that screen reader users do not need. If the same image becomes meaningful in another context, such as an article discussing the design itself, then it may need descriptive alt text there.

Question 9

What if an image contains text?

Accepted Answer

If important text appears only inside the image, include that text in the alt text. For example, a promotional banner that says "Summer Sale 40% Off" should preserve that offer if it is not repeated nearby as real text. If the same message already appears next to the image in HTML text, shorter alt text or empty alt text may be more appropriate.

Question 10

How should I write alt text for product images?

Accepted Answer

Describe the product type and useful visible details such as color, material, shape, pattern, style, quantity, or distinguishing features. A good product alt text might say "Brown leather backpack with brass buckles and two front pockets." Do not invent specifications that are not visible, such as size, brand, waterproofing, or compatibility, unless the page context clearly supports them.

Question 11

How should I write alt text for screenshots?

Accepted Answer

Describe the screenshot's purpose and the most important visible information. For a SaaS dashboard, mention the main screen and key data areas, such as revenue, orders, conversion rate, or traffic sources. Avoid listing every button, menu item, and small label unless the screenshot is part of documentation where those controls are the point of the image.

Question 12

How should I write alt text for charts?

Accepted Answer

Describe the chart type and main takeaway. A useful chart alt text might say "Line chart showing website traffic increasing from January to June." If exact data matters for understanding the content, add a longer explanation, table, or nearby text summary in addition to the alt text. Alt text alone should usually stay focused on the chart's main message.

Question 13

Can AI generate accessible alt text?

Accepted Answer

AI can create a strong first draft, especially when you add page context. It can identify visible objects, text, layout, and likely use cases, then suggest concise, descriptive, SEO-friendly, or decorative-image guidance. Human review is still important because accessible alt text depends on the image's purpose, accuracy, and surrounding content.

Question 14

Should I review AI-generated alt text before publishing?

Accepted Answer

Yes. Review AI-generated alt text before publishing, especially for medical, legal, educational, public-sector, ecommerce, chart, screenshot, or compliance-sensitive content. Check that the description matches the actual image, avoids unsupported assumptions, uses keywords naturally, and does not describe decorative images that should be skipped.
