Optimising Image Alt Text: Boost SEO and Accessibility Simultaneously

Have you ever wondered how search engines understand the content of images? Or why some websites rank higher in search results? The answer lies in a crucial yet often overlooked aspect of website optimisation: image alt text. 

We will explore the significance of image alt text and how you can optimise it to enhance both your website’s search engine optimisation (SEO) and accessibility. Let’s dive in!

Understanding Image Alt Text

Before we delve into optimisation techniques, it’s essential to understand what image alt text is and why it matters. Image alt text, or alternative text, briefly describes an image’s content. 

It plays a vital role in conveying the image’s context to search engines, visually impaired users, and individuals using screen readers. Providing accurate and descriptive alt text can enhance your website’s accessibility and ensure search engines can index and rank your images effectively.

Importance of Image Alt Text for SEO

Alt text significantly influences your website’s SEO by providing search engines with valuable information about your images. When optimising alt text, keeping a few key points in mind is essential. 

Firstly, the alt text should be concise, relevant, and specific to the image’s content. Secondly, incorporating relevant keywords in your alt text can help search engines understand the context of the image and improve its visibility in search results. However, it’s important to strike a balance between SEO optimisation and maintaining alt text’s purpose as an accessibility aid.

Crafting Effective Image Alt Text

Crafting effective image alt text requires a thoughtful approach. Start by analysing each image and determining its main subject or purpose. Then, create a concise, descriptive alt text that accurately conveys the image’s content. 

Avoid stuffing alt text with keywords or using generic phrases like “image1234.jpg.” Instead, aim to provide unique and meaningful descriptions. For example, if you have an image of a red bicycle, use alt text like “Red bicycle on a sunny day” instead of “Bicycle.”

Optimising Image Alt Text for Accessibility

Optimising alt text for accessibility is just as crucial as improving SEO. By following accessibility guidelines, you ensure that visually impaired user and those using screen readers can understand and engage with your website’s images. 

Ensure to provide alt text for all meaningful images and empty it for decorative or purely aesthetic images. Screen readers rely on alt text to provide meaningful descriptions, so clarity and accuracy are key. Additionally, consider using ARIA attributes, which provide additional context for complex images such as graphs or charts.

Best Practices and Common Mistakes

To optimise image alt text effectively, it’s essential to be aware of common mistakes to avoid. One common error is leaving alt text blank or using placeholder text, which provides no information to users or search engines. 

Another mistake is using alt text that is too long, leading to a poor user experience and potential keyword stuffing concerns. Lastly, avoid using alt text that is irrelevant or misleading, as this can misguide users and negatively impact your website’s accessibility and SEO efforts.

Testing and Monitoring Alt Text Performance

Once you’ve optimised the alt text on your website, it’s crucial to test and monitor its performance to ensure it’s delivering the desired results. 

Regularly evaluating and refining your alt text strategy can help you identify potential issues and make necessary improvements. Here are a few steps you can take:

  • User Testing: Conduct usability testing with visually impaired users or individuals who rely on screen readers to gather feedback on the effectiveness of your alt text. This valuable input can help you make adjustments and address any accessibility concerns.
  • SEO Analysis: Monitor your website’s search engine rankings and organic traffic to determine if your alt text optimisations positively impact your SEO efforts. Use analytics tools to track the performance of your optimised images in search results.
  • Alt Text Audit: Perform periodic audits of your website’s alt text to ensure consistency, accuracy, and relevance. Identify any missing or improperly formatted alt text and make the necessary updates.
