Definition
What Is Alt Text?
Alt text, short for alternative text, is a written description added to an image's HTML alt attribute. It helps people understand an image when they cannot see it, when the image fails to load, or when assistive technologies such as screen readers read the page aloud.
Good alt text depends on the image's purpose. A product image, decorative background, chart, screenshot, icon, and image with text all need different treatment.
An AI alt text generator can turn an uploaded image and page context into a strong first draft, but the final alt text should still be reviewed for accuracy, accessibility, and fit with the surrounding page.
Quality rules
What Makes Good Alt Text?
The best alt text is not always the longest description. It explains the image's purpose in the page context and avoids noise.
Good alt text is specific.
Name the meaningful subject, action, product, data, or visible text instead of using vague phrases like "image" or "photo."
Good alt text matches the page context.
The same image can need different alt text on a product page, blog post, documentation page, or accessibility audit.
Good alt text avoids keyword stuffing.
Use keywords only when they naturally describe the image. Lists of repeated SEO terms make alt text worse for users.
Good alt text does not describe every tiny detail.
Include details that help someone understand the image's role. Skip visual noise that does not matter.
Good alt text knows when to stay empty.
If an image is purely decorative and adds no meaning, use alt="" so screen readers can skip it.
Alt text examples

Image type: Product Image
Handmade Ceramic Tea Set
Page context
Ecommerce product page for a handmade ceramic tea set.
Weak alt text
Product photo.
Why it is weak
Too vague. It does not describe the product type, material, color, quantity, or visible details.
Better alt text
Speckled ceramic teapot with two matching cups and loose tea leaves on a linen tablecloth.
SEO-friendly version
Handmade ceramic tea set with matching cups and loose tea leaves on a natural linen tablecloth.
Accessibility note
For product images, describe the visible attributes that help shoppers understand what is being sold.
Why this works
It names the product clearly, includes useful visual details, and avoids generic wording like product photo.

Image type: Blog Image
Weekly Planning Workspace
Page context
Blog post about weekly planning and productivity.
Weak alt text
Person writing.
Why it is weak
Too broad. It misses the planning context and does not explain how the image supports the article topic.
Better alt text
Person writing in a weekly planner beside a laptop, coffee cup, desk plant, and notebook.
SEO-friendly version
Weekly planning workspace with a handwritten task list, laptop, coffee cup, and notebook.
Accessibility note
For blog images, describe the visible action and connect it to the topic without turning the alt text into a keyword list.
Why this works
It explains the activity, includes relevant scene details, and supports the productivity topic naturally.

Image type: Software Screenshot
Product Analytics Dashboard
Page context
SaaS landing page showing a product analytics dashboard.
Weak alt text
Dashboard screenshot.
Why it is weak
Too generic. It says the image is a screenshot but does not explain what the dashboard shows.
Better alt text
Analytics dashboard showing revenue, orders, conversion rate, average order value, traffic sources, and performance charts.
SEO-friendly version
Product analytics dashboard with revenue, orders, conversion rate, and traffic source charts.
Accessibility note
For screenshots, describe the purpose and main visible information instead of listing every button or small UI element.
Why this works
It summarizes the screen at a useful level of detail and helps users understand what the interface communicates.

Image type: Chart or Infographic
Website Traffic Growth Chart
Page context
Report section explaining website traffic growth.
Weak alt text
Chart.
Why it is weak
Too vague. It does not identify the chart type, metric, time range, or trend.
Better alt text
Line chart titled Website Traffic Growth showing monthly sessions increasing from 15K in January to 58K in June.
SEO-friendly version
Website traffic growth chart showing monthly sessions rising from January to June.
Accessibility note
For data charts, include the chart type, metric, time range, and main trend. Add a longer explanation nearby when exact data matters.
Why this works
It captures the key insight from the chart instead of only naming the visual format.

Image type: Image with Text
Summer Sale Banner
Page context
Promotional banner where the offer is not repeated nearby as real page text.
Weak alt text
Sale banner.
Why it is weak
It misses the actual offer. If the text inside the image is not repeated nearby, users may lose important information.
Better alt text
Summer Sale 40% Off promotional banner with beach imagery.
SEO-friendly version
Summer Sale 40% Off promotion banner for a seasonal beach-themed campaign.
Accessibility note
Important text inside an image should be included in the alt text when it is not available as real page text.
Why this works
It preserves the message users need from the image and avoids describing only the decoration.

Image type: Decorative Background
Abstract Blue Wave Background
Page context
Abstract background shape behind a section heading.
Weak alt text
Blue abstract background.
Why it is weak
The image is decorative, so describing it adds noise for screen reader users.
Better alt text
alt=""
Accessibility note
Decorative images usually need an empty alt attribute so assistive technology can skip them.
Why this works
The image does not add meaningful content, so hiding it from screen readers improves the experience.

Image type: Functional Icon
Search Button Icon
Page context
Magnifying glass icon used as a search button.
Weak alt text
Magnifying glass icon.
Why it is weak
It describes the icon's appearance, not the action the button performs.
Better alt text
Search.
Accessibility note
For functional images, describe the action or purpose, not the visual appearance.
Why this works
A screen reader user needs to know what the control does, not what shape the icon has.

Image type: Accessibility-Related Image
Screen Reader Workflow
Page context
Article about inclusive web design and screen-reader workflows.
Weak alt text
Accessibility image.
Why it is weak
Too vague. It labels the topic but does not describe the visible activity or assistive technology.
Better alt text
Person wearing dark glasses and headphones using a laptop with a braille display device on the desk.
SEO-friendly version
Screen-reader workflow with a laptop, headphones, and braille display device.
Accessibility note
Avoid guessing identity or disability beyond what the image and page context support. Describe visible assistive technology when relevant.
Why this works
It explains the meaningful activity and includes grounded details without making unnecessary assumptions.

Image type: Fashion or Lifestyle Image
Summer Fashion Crosswalk
Page context
Street style collection page for a seasonal fashion editorial.
Weak alt text

SEO-friendly version
Street style outfit with a camel coat, white sneakers, and green tote bag.
Accessibility note
For fashion images, describe clothing, color, styling, and visible accessories that matter for the page.
Why this works
It helps shoppers understand the outfit without overloading the description with unnecessary background details.

Image type: Travel or Architecture Image
Modern Glass Office Building
Page context
Editorial article about modern city architecture.
Weak alt text
Building.
Why it is weak
Too vague. It does not describe the architecture style, setting, or visible surroundings.
Better alt text

SEO-friendly version

}FAQ
Alt Text Generator FAQ
What is alt text?
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.
What is an alt text generator?
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.
What makes good alt text?
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.
What is bad alt text?
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.
Does alt text help SEO?
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.
Can I use keywords in alt text?
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.
Should every image have alt text?
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.
What should I do with decorative images?
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.
What if an image contains text?
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.
How should I write alt text for product images?
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.
How should I write alt text for screenshots?
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.
How should I write alt text for charts?
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.
Can AI generate accessible alt text?
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.
Should I review AI-generated alt text before publishing?
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.
