Statistics indicate that there are millions of internet users with visual impairments or low vision who rely on screen readers to access online information.

Best Practices for Alt Text
When it comes to writing alt text, following best practices is essential. By implementing these guidelines, you can ensure that your alt text is descriptive, relevant, and contributes to improved SEO and web accessibility.
1. Be Descriptive and Specific
Provide a concise description of the image that accurately represents its content and function. Avoid generic or vague alt text and instead focus on capturing the key details of the image. For example, instead of using “woman,” describe her specific role or activity in the image.
2. Use Relevant File Names
Before uploading an image, ensure the file name is descriptive and includes relevant keywords. This not only helps search engines understand the image but also provides additional context for alt text. For example, an image named “young-girl-playing-soccer.jpg” can have alt text like “young girl playing soccer in a park.”
3. Consider the Image’s Context
Take into account the image’s purpose within the webpage and its intended audience. Tailor the alt text to align with the larger context and content of the page. This ensures that users with visual impairments or those relying on screen readers can fully understand the significance of the image within the overall narrative.
4. Avoid Keyword Stuffing
While it’s important to include relevant keywords in alt text, avoid keyword stuffing. Overloading alt text with keywords hampers accessibility and can harm your SEO efforts. Prioritize natural language and meaningful descriptions that accurately convey the image’s content.
5. Include Schema Markup
Consider leveraging schema markup to provide additional context to search engines. Schema markup allows you to specify the image’s subject matter, location, or other relevant details. This can enhance the visibility of your image in search results and improve its overall ranking.
Visualizing Best Practices for Alt Text
To further illustrate these best practices, let’s consider an example scenario where alt text is being used for an image showing a dog playing fetch in a park. The alt text could be:

Alt text also provides valuable context to search engines, enabling them to understand and rank images appropriately. Let’s explore the impact of alt text on SEO, accessibility, and image optimization.
Enhancing Accessibility
Alt text ensures that visually impaired users can access and understand on-page images. Screen readers, used by people with visual impairments, read aloud the alt text, allowing them to perceive the visual content. By including descriptive alt text, websites demonstrate their commitment to web accessibility and create a more inclusive online experience for all users.
Improving SEO Rankings
Search engines rely on alt text to understand the content and relevance of images. By providing accurate and descriptive alt text, websites can enhance their SEO efforts and improve their chances of ranking higher in search engine results. Proper image optimization, including the use of relevant alt text, can drive organic traffic from image search results.
Optimizing Image Context
Alt text provides valuable context to search engines, enabling them to index and rank images appropriately. Without alt text, search engines may struggle to understand the purpose or subject matter of the image, leading to missed opportunities for visibility and relevance in search results. By using descriptive alt text, websites can ensure that search engines correctly interpret and display their images.
Maximizing User Experience
Improved accessibility and proper image optimization contribute to a better overall user experience. By including descriptive alt text, websites provide visually impaired users with a rich understanding of the visual content present on the page. This enhances engagement and satisfaction among all users, regardless of their visual ability.
Alt text should be an integral part of your SEO strategy, combining accessibility and image optimization to maximize the impact of your visual content on the web.

Alt Text and Web Accessibility
Alt text is a vital component of web accessibility, ensuring that individuals with visual impairments can access and comprehend on-page images. For those who rely on screen readers, alt text provides essential information about the content and context of the image. By incorporating descriptive alt text, websites can enable visually impaired users to fully engage with their content, bridging the accessibility gap.
Screen readers, which read aloud the alt text, offer visually impaired individuals the opportunity to understand the meaning and purpose of images found on web pages, making the online experience more inclusive.
Without alt text, users who can’t see the images would miss out on valuable information and context, potentially leading to a less engaging and meaningful user experience. Web accessibility guidelines highlight the importance of alt text and its role in ensuring that all users, regardless of visual abilities, can fully comprehend and engage with web content.
Organizations should prioritize the implementation of descriptive alt text as a fundamental aspect of their web accessibility strategy. By doing so, they contribute to creating an inclusive and accessible online environment for all users.
The Role of Screen Readers
Screen readers are software applications that people with visual impairments use to navigate and engage with digital content. These assistive technologies read aloud the content of a web page, including alt text, enabling visually impaired individuals to access information that would otherwise be inaccessible.
| Benefits of Alt Text for Web Accessibility |
|---|
| Enables visually impaired individuals to access and understand on-page images |
| Provides important context and information about the content of the image |
| Ensures a more inclusive and accessible online experience |
“Alt text allows visually impaired users to access and comprehend images, enhancing their overall browsing experience and enabling equal access to information.”
Implementing Descriptive Alt Text
When adding alt text to images, it is crucial to provide concise yet descriptive descriptions that accurately convey the content and purpose of the image. Consider the following guidelines when implementing alt text:
- Keep alt text concise, typically within 125 characters to accommodate screen reader limitations.
- Describe the image objectively, focusing on its content and function rather than its appearance.
- Avoid keyword stuffing in alt text, as it can negatively impact SEO and create a poor user experience.

By adhering to these best practices, website owners and content creators can ensure that alt text effectively communicates essential information to visually impaired users, promoting web accessibility and a more inclusive online experience.
How to Add Alt Text to Images
When it comes to optimizing your website for accessibility and SEO, adding alt text to images is a crucial step. Fortunately, content management systems (CMS) make this process easy and straightforward.
When you upload an image to your CMS, you will typically find fields or options to add alt text. Take advantage of these features by providing descriptive and relevant alt text that accurately describes the image. This alt text serves as an alternative description for users who cannot see the image, such as those with visual impairments.
You can add alt text either within the HTML code or by using the dedicated alt text field in your CMS. Remember to follow alt text best practices and guidelines when writing your alt text. This ensures that your alt text is concise, meaningful, and contributes to a positive user experience.
