*SEO Week day 1 thought #11.*

Under the hood, search and AI systems are representing pages, queries, entities and even users as *vectors* in a high-dimensional embedding space. That is where semantic relevance really lives. Historically, SEO tools exposed the link graph because PageRank mattered most. Today, the question “Where do we sit in vector space for this topic?” is just as important as “What’s our ranking?” If we want AI visibility, we need to start thinking about our semantic neighborhoods (and their centroids), not just our backlinks and keyword positions.
