    TF-IDF

    Last updated:

    Quick definition: TF-IDF (Term Frequency-Inverse Document Frequency) measures how important a word is to a document relative to a collection of documents, used by Google to assess whether content covers a topic with appropriate depth and terminology.

    What it means

    TF-IDF compares how often a term appears in your document versus how often it appears across a reference corpus. Terms that are common in your topic but rare overall are statistically meaningful and are expected to appear in expert content on that topic.

    Tools like Surfer, Frase, and Clearscope use TF-IDF analysis to recommend missing entities and terms.

    Why it matters for real estate SEO

    Real estate agents writing neighbourhood guides who omit key terms (school district names, transit lines, signature streets) score poorly in TF-IDF analysis and rank below competitors who cover the topic comprehensively.
