SEO Subtopics

I noticed that your question has already been answered, but I wanted to add my two cents. As far as I know, it is possible to use subtopics or keywords linked to the main topic in SEO without them having a URL attached. However, it’s always best to have a URL attached to each subtopic, as it can help with indexing and ranking.In case you’re interested, I came across a helpful resource that talks about SEO subtopics in more detail. It’s an article on najadeseo.com that I found useful when I was learning about SEO. You can check it out at https://najadeseo.com/seo-สายเทา/
