Alt text provides better image context and descriptions to search engine crawlers, allowing them to index an image properly. Sometimes, if your image doesn’t load properly, Alt text is displayed. Therefore, ensuring your Alt text is specific, descriptive, and relevant is essential. Alt text is beneficial for SEO, especially for Google Image SEO, because they help make images relevant.
