Hi! @russhowepti, It’s completely fine to use the same image on different pages with different alt texts. The alt text is meant to describe what’s in the image for the benefit of people who can’t see it, as well as for search engines.
In the case of your fitness blog, you’re using the same image of a protein shake in two different contexts. One is simply describing the image (‘protein shake’) while the other is providing more specific advice or information (‘eat protein to build muscle’). Both are valid descriptions for the image, depending on the context in which it’s used.
However, remember that the alt text is a factor that search engines use to understand the content and context of the page. If the alt text of the image varies greatly between pages and doesn’t align well with the content of the pages, it might lead to confusion for search engine crawlers. In your example, both descriptions fit well in a fitness context, so it’s unlikely to cause an issue.
In a nutshell, as long as the alt text accurately describes the image and aligns with the page’s content, it’s fine to use the same image with different alt texts on separate pages.
