How can I effectively optimize my website's Alt text for SEO?

[Neonmalwer456]

I'm having trouble with the Alt text on my website, it's not properly organized. I want to adopt the same Alt text format used by other websites like virtual sales assistant. My website advertises available apartments for sale in Baabda, but I haven't optimized the Alt text for SEO. I need to check if the Alt text is embedded in the code and if it's not, I want to know how to add it in JSON format. Any help would be greatly appreciated. Thank you.
