What is Alt Text?
Alt text is a brief written description of an image that appears when the image cannot be displayed or accessed by a user. It serves to provide context and improve accessibility for visually impaired users, while also helping search engines understand the content of images.
In-Depth Explanation of Alt Text
Why It Matters
Alt text plays a crucial role in making websites accessible to people with visual impairments or those using assistive technologies. It ensures that all users, regardless of their ability to see images, can understand the content and purpose of visual elements on a page. Additionally, it contributes to better search engine optimization (SEO) by helping search engines understand and index image content.
How It Works
When an image is added to a webpage, developers include an “alt” attribute in the HTML code. This attribute contains a concise description of the image. Screen readers and other assistive technologies read this description aloud, allowing users to understand the image’s content and context. If an image fails to load, browsers display the text in place of the image.
Key Benefits
Implementing alt text improves website accessibility, making it easier for people with disabilities to navigate and understand your content. It enhances user experience for all visitors, especially those with slow internet connections or when images fail to load. It also boosts SEO efforts by providing additional context for search engines to understand and rank your content.
Relevant Stats or Facts
The World Health Organization reports that approximately 2.2 billion people worldwide have a vision impairment or blindness. According to Google, the most important attribute when it comes to providing more metadata for an image is the alt text, since it enhances accessibility.
Importance of Alt Text
Alt text plays a crucial role in making websites and digital content accessible to everyone, including people with visual impairments. For businesses, implementing effective alt text is not just about compliance with accessibility guidelines; it’s about reaching a wider audience and providing a better user experience for all customers. By adding descriptive text to images, businesses ensure that screen readers can convey the information to users who rely on them, allowing these customers to fully engage with the content and make informed purchasing decisions.
In the realm of product data management and eCommerce, alt text becomes even more significant. When shoppers browse online catalogs or product listings, images are often the primary way they evaluate items before making a purchase. However, if a customer cannot see the images, they may abandon their shopping journey, resulting in lost sales opportunities. By crafting clear and concise alt text for product images, businesses can provide valuable information about their offerings, such as color, size, or unique features, enabling all potential customers to make confident buying choices regardless of their visual abilities.
Furthermore, alt text contributes to improved search engine optimization (SEO) for businesses. Search engines rely on it to understand and index images, which can help boost a website’s visibility in image search results. This increased visibility can lead to higher traffic, more potential customers, and ultimately, increased revenue. By prioritizing alt text in their digital strategy, businesses not only demonstrate their commitment to inclusivity but also gain a competitive edge in the online marketplace.
Examples of Alt Text
Fashion/Apparel Retailer:
For a fashion retailer, alt text can significantly enhance the accessibility and searchability of online products. For example, an image of a women’s floral summer dress may have text like “Women’s blue floral summer dress with short sleeves and a V-neck, perfect for casual outings or vacation wear.” This description not only makes it accessible for visually impaired shoppers using screen readers but also improves the image SEO, helping potential customers find the product while searching for specific features like “floral summer dress.”
HVAC Manufacturer:
An HVAC manufacturer can use alt text to provide detailed descriptions of their products‚ technical aspects. For an image of a central air conditioning unit, the text could read, “Central air conditioning unit with a high-efficiency compressor and noise reduction technology, suitable for residential and commercial use.” This information helps users who rely on assistive technologies and supports the technical search queries of professionals looking for specific HVAC systems online.
Distributor of Auto Parts:
When it comes to auto parts, precise alt text is crucial due to the need for accuracy and compatibility. An image showing a brake rotor might have alt text such as “High-performance front brake rotor for 2015-2020 Ford F-150, made from premium quality cast iron for enhanced durability.” Such detailed text ensures users and search engines quickly identify the part’s compatibility and features, reducing errors in purchases and improving customer satisfaction.
Brand Owner of Homewares Products:
For homewares products sold on various marketplaces, alt text must effectively distinguish products among a sea of similar listings. An image of a ceramic dinnerware set might use alt text like “12-piece white ceramic dinnerware set including plates, bowls, and mugs with a scratch-resistant gloss finish, suitable for everyday dining or special occasions.” This description not only aids accessibility but also emphasizes unique selling points, improving visibility and appeal on platforms like Walmart, Lowe’s, Home Depot, and Wayfair.

Alt Text and PIM
Alt Text, short for Alternative Text, is a crucial element in digital content management and accessibility. It provides a textual description of images, allowing users who cannot see the images to understand their content and purpose. In the context of Product Information Management (PIM) solutions, it plays a significant role in enhancing product visibility, improving search engine optimization, and ensuring a more inclusive online shopping experience.
PIM solutions incorporate Alt Text as an essential attribute for product images. When managing product data, these systems allow users to input descriptive text for each image associated with a product. This text serves multiple purposes. For search engines, it provides context about the image content, potentially improving the product’s visibility in image search results. For visually impaired users relying on screen readers, it offers a verbal description of the product image, enabling them to understand what the product looks like and make informed purchasing decisions.
The implementation of alt text in PIM solutions also supports multichannel marketing efforts. As products are distributed across various platforms such as e commerce websites, mobile apps, and social media, the associated text travels with the product data. This ensures consistent and accurate image descriptions across all channels. For example, a furniture retailer using a PIM solution could input it for a sofa image describing its color, material, and style. This description would then be available on their website, mobile app, and any third party marketplaces they use, providing a uniform experience for all customers regardless of their preferred shopping platform or visual abilities.
Frequently Asked Questions
Why is alt text important for my business website?
Alt text helps make your website more accessible to people with visual impairments who use screen readers. It also improves your search engine optimization (SEO) by providing context for images, which search engines can’t interpret on their own. This can lead to better rankings in search results and increased visibility for your business online. Additionally, alt text ensures that if an image fails to load, users still understand what the image was meant to convey, maintaining a smooth user experience.
How long should alt text be?
Aim to keep your alt text concise and descriptive, typically between 50 to 125 characters. This length allows you to provide enough information without overwhelming users or search engines. Focus on describing the most important aspects of the image that are relevant to your content or product. If you need to include more details, consider adding them to the surrounding text or image caption instead. Remember that brevity and clarity are key when writing effective alt text.
Should I use keywords in alt text?
While it’s acceptable to include relevant keywords in your alt text, avoid keyword stuffing. Your primary goal should be to accurately describe the image content. If a keyword naturally fits the description, include it, but don’t force it. Overusing keywords in alt text can be seen as spam by search engines and may negatively impact your SEO efforts. Instead, focus on creating clear, concise descriptions that provide value to users and search engines alike.
Do I need to add alt text to decorative images?
For purely decorative images that don’t convey any meaningful information, you can use empty alt text (alt=””). This tells screen readers to skip over the image. However, be cautious about labeling images as decorative, as many images that seem decorative may still provide context or enhance the user experience. When in doubt, it’s better to provide a brief description rather than omit alt text entirely. This approach ensures that all users, regardless of their abilities, can fully engage with your content.
How can I audit my website for missing or poor alt text?
There are several ways to check your website for alt text issues. Use automated tools like web accessibility checkers or SEO analyzers that can scan your site and flag missing or inadequate alt text. Manual reviews are also important, as they allow you to assess the quality and relevance of existing alt text. Regularly review your product images and content updates to ensure new additions have appropriate alt text. Consider involving team members with different perspectives to help identify areas for improvement and maintain consistency across your site.
