Alt Text Guide: Write Effective, SEO-Friendly Descriptions

Ever wondered what those little text descriptions are that appear when an image fails to load on a website? That is alt text, or alternate text, a critical aspect in web content that is frequently disregarded. Let’s look at what alt text is, why it’s important, and how to create it properly to improve your website’s accessibility and SEO.

What is alt text?

Definition and purpose

Alt text, or alternative text, is a brief description of a picture contained in HTML code. It replaces a picture if it fails to load and helps search engines comprehend what the image is about. More crucially, alt text makes content accessible to visually challenged users who use screen readers.

History of Alt Text

The concept of alt text emerged with the emergence of the web and HTML. Initially, it was intended to increase web accessibility and assist with sluggish internet rates by displaying written descriptions when images failed to load.

Why is Alt Text important?

Accessibility

Alt text is essential for making web information accessible to all users, including those with visual impairments. Screen readers use alt text to describe visuals, allowing visually impaired people to fully grasp and interact with the material.

SEO Benefits:

Because search engines cannot directly comprehend images, they must rely on alt language to analyze and index visual material. This improves your site’s search engine ranks and visibility, particularly in image search results.

User Experience

Good alt text improves the user experience by offering context and information, especially when images fail to load due to technical reasons.

How Alt Text Improves Accessibility

Screen Readers and Visually Impaired Users

Screen readers transform digital text into spoken words and employ alt text to describe visuals. This ensures that visually impaired users may understand the content as well as sighted people.

Legal requirements

Many nations have legislative requirements for web accessibility, such as the usage of alternative text. For example, the Americans with Disabilities Act (ADA) in the United States requires accessible web content.

• Alt text has SEO benefits, including improved search engine crawlability.
• Search engines employ alt text to crawl and index photos.
• Properly captioned photos can improve your site’s SEO by making your material easier to find and understand for search engines.

Image Search Visibility.

Alt text improves the visibility of your photographs in search engine results. Well-written alt text can increase traffic to your website via picture searches.

Impact on Page Ranking

Images with good alt text contribute to a higher SEO score, which can boost your overall page ranking in search engine results pages (SERPS).

Best Practices for Writing Alternative Text

Be descriptive yet concise.

Describe the image in enough detail to provide context while keeping it succinct. Strive for a balance between being informed and concise.

Avoid keyword stuffing.

Include important keywords naturally, but avoid stuffing your alt text with keywords. Keyword stuffing might do more harm than good to your SEO.

Relevance to Images and Context

Ensure that your alt text appropriately represents the image content and its context on the page. Misleading alt text can confuse both users and search engines.

Avoid these common mistakes: – Using vague descriptions.

Avoid ambiguous descriptions that do not convey relevant information. For example, “flower” is too ambiguous, whereas “red rose in a vase” is more specific.

• Redundant use of phrases such as “image of”
• There is no need to begin with “image of” or “picture of.” Screen readers instantly recognize items as images.

Ignoring Context.

Ensure that your alt text is consistent with the surrounding material. An out-of-context description can perplex users and disrupt the flow of information.

Alt text examples are descriptive.

• “Golden retriever playing fetch in a park.”
• “Aerial view of downtown Chicago skyline at sunset.”

Contextual Examples:

• “New iPhone 13 Pro Max in silver color on a wooden table.”
• “Delicious vegan lasagna with fresh basil on top.”
• Bad alt text examples include those that are overly simple.

“Dog” “City”

• Keyword Stuffed Examples
• “Cheap golden retriever puppies for sale park fetch” “Chicago best sunset skyline downtown skyscrapers”
• Alt text for many types of images.
• Decorative images.
• To avoid overwhelming screen readers with unnecessary information, use an empty alt attribute (alt=””).

Informative Images

Describe the contents and purpose. Examples include: “Bar chart showing quarterly sales growth from 2019 to 2021.”

Functional Images

Describe the role of images used as links or buttons. For example, “Submit button” and “Home page link.”

Tools for creating and evaluating alt text, including automated tools.

Tools such as Google’s Lighthouse and WAVE can assess your website’s accessibility and make recommendations for improving alt text.

Manual Checks

Manually evaluate your alt text on a regular basis to verify that it is still accurate and relevant when your content changes.

Alt text can be added in various platforms, including WordPress.

When you upload images to WordPress’s media library, you can add alt text directly.

Shopify

Shopify allows you to provide alt text for photos in the product media area.

• Social Media (Instagram, Facebook, and Twitter)
• When posting photographs to most social networking platforms, you can choose to include alt text. Use these features to enhance accessibility and SEO.
