¿Qué muestra la métrica TF-IDF de On Page SEO Checker?

TF-IDF (Term Frequency-Inverse Document Frequency) is a numerical statistic reflecting the importance of a word to a document within a collection or corpus. It increases proportionally to the number of times a word appears in the document but is offset by the frequency of the word in the corpus, which helps to adjust for the fact that some words appear more frequently in general. Therefore, it shows the importance of a word for a specific document. "Cuántas veces se utilizó una palabra clave en una URL" describes term frequency, only one component of TF-IDF. "Cuáles palabras clave perciben mejor las personas" relates to user perception, not a direct measure of TF-IDF. "Cómo ve la palabra clave un motor de búsqueda" is too general; TF-IDF is one factor, but not the sole determinant. "El tráfico mensual aproximado anticipado para una palabra clave" is a keyword research metric, not TF-IDF.
