Understanding Image Alt Text
Image alt text, or alternative text, is a short written description of an image on a webpage. It serves multiple purposes: improving web accessibility for individuals with disabilities, enhancing SEO by helping search engines understand the content of images, and providing context when images fail to load. Alt text acts like a silent guide, ensuring that all users, regardless of their browsing capabilities, understand the visual content of your site.
The Importance of Image Alt Text
Accessibility
One of the primary functions of alt text is to enhance web accessibility. For users with visual impairments, screen readers interpret alt text, allowing these users to understand the content of images. This is crucial not only for inclusivity but also for reaching a wider audience. As assistive technologies become more prevalent, having accessible websites will be increasingly important.
User Experience (UX)
Slow internet connections or technical issues can prevent images from loading. In such cases, alt text provides a textual representation of the image, ensuring users are not left in the dark about the content they are missing. This improves the overall user experience, as visitors can still grasp the essential information even without visuals.
Search Engine Optimization (SEO)
From an SEO perspective, alt text is a valuable tool. It helps search engines understand the content of images, which can improve your site’s visibility in search results. By incorporating relevant keywords naturally into your alt text, you enhance your chances of appearing in image search results, driving more traffic to your site. For example, instead of a generic “sun hat,” using “wide-brimmed dark brown canvas sun hat” can target specific search queries more effectively.
How to Add Image Alt Text
Most content management systems (CMS) provide straightforward methods for adding alt text. In Shopify, for instance, you can add alt text when uploading images or edit it later through the media library. For those coding manually, the alt attribute is included within the <img> tag, like so: <img src="image.jpg" alt="Your alt text here">.
Adding Alt Text in Shopify CMS
- Navigate to your Shopify admin and select the product you wish to edit.
- Click on the product media item to access the preview media page.
- Enter your alt text in the designated field and save your changes.
Writing Effective Alt Text
Be Specific but Concise
Effective alt text should be descriptive yet succinct, ideally under 125 characters. Describe the image content clearly, focusing on what is essential for understanding it. Avoid starting with “image of” or “picture of,” as screen readers typically add this automatically.
Avoid Duplicative Text
If the image’s message is already conveyed in the surrounding text, avoid redundancy. Instead, focus on what the image adds to the content without repeating information unnecessarily.
Use Keywords Wisely
Incorporate relevant keywords into your alt text to enhance SEO, but avoid keyword stuffing. The text should remain natural and coherent, reflecting the actual content of the image.
Omit Alt Text for Decorative Images
For images that are purely decorative, such as background designs or simple graphics, alt text is unnecessary. An empty alt attribute (alt="") signals screen readers to skip these images, preventing unnecessary interruptions for users relying on these technologies.
FAQs About Image Alt Text
What is the alt text of an image?
Alt text is a brief description of an image added via the alt attribute in HTML. It’s used by screen readers for visually impaired users and helps with SEO by allowing search engines to understand image content.
What is the difference between alt text and image description?
Alt text is hidden unless an image fails to load, whereas an image description or caption is always visible. Alt text should succinctly describe the image for users who cannot see it, whereas descriptions provide additional context.
What are the rules for alt text?
Best practices include using specific language, considering the image’s context, and omitting alt text for purely decorative images.
What is a good example of alt text?
Effective alt text is specific and contextually relevant. For instance, “A plate of chicken wings next to a bottle of Spicy Jane’s Chili Oil” clearly describes the image and includes relevant keywords for SEO.
In conclusion, while image alt text might seem like a small detail, it plays a pivotal role in enhancing both the accessibility and SEO of your eCommerce website. By crafting thoughtful and effective alt text, you ensure that your site is welcoming and accessible to all users, while also improving your search engine rankings. Embrace alt text as a strategic tool in your digital marketing arsenal, and watch your online presence thrive.
