The error 'This image has an empty alt attribute' typically occurs when the 'alt' attribute of an '<img>' HTML tag is left empty or is missing. The 'alt' attribute is used to provide alternative text for an image if it cannot be displayed, and it also helps with accessibility, particularly for visually impaired users who utilize screen readers. Additionally, search engine bots use the 'alt' attribute to understand what an image is about, which can impact your SEO.
Resolving the 'This image has an empty alt attribute' error is straightforward.
Identify any images on your website that are missing an 'alt' attribute or have an empty one. This may involve reviewing your site's HTML code or using a tool to crawl your site and identify missing or empty 'alt' attributes.
Once identified, add a relevant and descriptive 'alt' text to each image. Ensure that the 'alt' text accurately represents the content of the image. For example, if you have an image of a sunset over a city, an appropriate 'alt' text might be 'sunset_over_city'.
Avoid stuffing keywords into your 'alt' text. While it is important for SEO, Google's guidelines recommend making 'alt' text useful for users first and foremost.
Regularly check and update 'alt' text as needed. New images added to your site should always include appropriate 'alt' text.
By following these steps, you can resolve the 'This image has an empty alt attribute' error, improve accessibility on your site, and enhance your SEO efforts.
