Definition of Alt Text

Alt text, also referred to as alternative text, plays a vital role in providing a written description for online images. It serves as an alternative when the image cannot be accessed by users.

This description is particularly beneficial for individuals with visual impairments who rely on screen readers to understand website content. Moreover, alt text also assists search engine bots in comprehending the contents of an image and may even be displayed on a webpage if the image fails to load.

It is important to note that alt text differs from image captions, as captions are always visible on the page itself. Alt text, on the other hand, remains hidden in the website’s HTML code and is added through the alt attribute. This attribute is commonly known as the “alt attribute” or “alt tag” and is typically included in the image’s HTML code like this:

<img src=”image-file-example.jpg” alt=”Alt text goes here” />

Many content management systems (CMSs) offer dedicated fields for adding alt text, eliminating the need to directly edit the HTML. For instance, in WordPress, you can easily add alt text through the “Alt Text (Alternative Text)” dialogue box.

Notably, alt-text usage extends beyond websites and can also be employed on social media platforms like Twitter. This means that when sharing images on Twitter, you have the option to include alt text for images to provide a descriptive label.

By understanding the significance of alt text and utilising it effectively, you can enhance both accessibility and search engine optimisation (SEO) for your website. It ensures that individuals with visual impairments can access and comprehend your content, while also enabling search engines to index and rank your images appropriately.

The Significance of Alt Text

Alt text plays a crucial role in improving the accessibility of images for both users and search engines, even when the images cannot be displayed. Failing to provide appropriate alt text can exclude individuals with visual impairments who rely on screen readers to access information from images. This exclusion not only has the potential to harm your brand reputation but can also negatively impact website traffic and conversion rates.

Moreover, incorporating alt text is not only essential for accessibility but also beneficial for SEO. Search engines like Google utilise alt text to understand the context and content of images, leading to improved rankings in search results. Alt text is especially advantageous for image SEO, as it can contribute to higher visibility in Google Images and other image-based search results. This increased exposure can drive valuable traffic to your website.

For instance, when searching for “corgi puppies,” the search engine results page (SERP) predominantly displays images that link directly to the respective owners’ websites. This highlights the significance of optimising alt text to enhance visibility and attract organic traffic.

Best Practices for Writing Alt Text

Discover effective techniques for crafting alt text that enhances both the accessibility and SEO of your website. Here are three valuable best practices to guide you:

• Optimise Alt Text for Relevant Images

  When writing alt text, focus on images that convey meaningful information rather than purely decorative ones. Descriptions for decorative images can potentially distract or confuse users with visual impairments. By reserving alt text for images with contextual significance, you ensure that users receive valuable information.

• Balancing Description and Brevity

  The Web Accessibility Initiative (WAI) recommends creating concise descriptions that capture the image’s purpose effectively. Consider the surrounding content and your target audience when writing alt text. For instance, using “Woman doing yoga” as alt text would generally be appropriate. However, in a workout guide, a more detailed description of the specific yoga pose may be necessary to provide comprehensive context.

• Incorporate Relevant Keywords

  Integrating relevant keywords into your alt text can boost the visibility of your images in Google image results. By doing so, you signal to search engines the content and relevance of the image.

For example, if your alt text states “marketing funnel illustration” alongside an actual marketing funnel illustration, it becomes more likely to appear in Google image results for queries related to marketing funnels.

To determine which keywords to include in your alt text, conduct thorough keyword research, ensuring alignment with your content and target audience.

Illustrative Examples of Alt Text

When it comes to providing illustrative examples of alt text, let’s explore two scenarios—one related to Instagram and the other showcasing general alt text examples:

• Alt Text on Instagram:

  Suppose you have an image of a beautiful sunset shared on Instagram. To provide alt text for this image, you can write something like: “Vibrant sunset over the beach, casting warm hues across the sky and reflecting on the calm ocean waves.” This alt text accurately describes the image and allows individuals using screen readers to envision the captivating scene.

• General Alt Text Examples: Here are a few examples demonstrating alt text for different types of images:

  • Image of a Dog Playing Fetch: Alt Text: “Golden Retriever joyfully chasing a tennis ball during a game of fetch in the park.”

    Image link: [image of dog playing fetch]

  • Illustration of Eiffel Tower: Alt Text: “Artistic illustration of the iconic Eiffel Tower in Paris, surrounded by a blue sky and greenery.”

    Image link: [image of the Eiffel Tower]

  • Product Photo of a Laptop: Alt Text: “Sleek silver laptop with a high-resolution display, backlit keyboard, and slim design.”

By using descriptive alt text like the examples provided, you enable users to comprehend the content and context of the images, regardless of their visual abilities.

Remember, the alt text should always reflect the content of the image and be concise yet informative, allowing users to grasp the essence of the visual element.

Locating and Correcting Missing Alt Text

Locating and correcting missing alt text is a crucial step in ensuring accessibility and optimising your website for both users and search engines. Here’s a breakdown of the process and some valuable tips to help you address this issue:

• Identifying Missing Alt Text: To locate missing alt text, you need to review each image on your website and identify those that lack descriptive alternative text. Start by inspecting the HTML code of your web pages and search for <img> tags without the alt attribute. You can also utilise website accessibility evaluation tools and browser extensions that can scan your website and provide a report highlighting any missing alt text.
• Prioritising Important Images: Once you’ve identified the images without alt text, prioritise addressing those that convey crucial information or serve as functional elements on your website. Images that are purely decorative or have no meaningful context may not require alt text.
• Crafting Descriptive Alt Text: When writing alt text for missing or incomplete descriptions, ensure that you accurately describe the image’s content or purpose. Focus on providing relevant details that convey the message effectively. Aim for a balance between conciseness and comprehensiveness, tailoring the alt text to suit the image and its context.
• Implementing Alt Text: To add alt text to your images, locate the <img> tag in the HTML code corresponding to the image and include the alt attribute within the tag. Write the descriptive alt text within the quotation marks of the attribute. For example: <img src=”image-file.jpg” alt=” Descriptive alt text goes here”>. Alternatively, if you are using a content management system (CMS), utilise the dedicated alt text fields provided to add or edit alt text without directly modifying the HTML code.
