📐 How Semantic Similarity Works
We compute a TF-IDF centroid vector from each domain’s crawled pages (up to 1,000 per domain). The centroid represents the “semantic soul” of the website — the mathematical average of all its content. We then measure cosine similarity between centroids to find the closest alternatives. Higher overlap means the two sites cover the same topics with similar depth.
