TF-IDF content audits tell you which words your competitors use. This one tells you the STRUCTURAL signals they all share: heading depth, schema types, media ratio, word-count band, internal-link density. The shape that wins a SERP is the shape a new contender needs to ship. MarketMuse and Clearscope bundle this for $149-$199/month. Yours is free.
