TF-IDF signifie fréquence-inverse de la fréquence du document utilisée pour mesurer l'importance d'un mot clé donné sur une page. Contrairement à la densité des mots clés, il ne se contente pas de regarder le nombre de fois où le terme est utilisé sur la page ; il analyse également un ensemble plus large de pages et tente de déterminer l'importance de tel ou tel mot clé.
Par exemple, dans la réparation automobile, le terme "réparation de pneus" est susceptible d'être plus important que "réparation de moteur turbocompressé" - essentiellement parce que chaque voiture a des pneus, et seulement un petit nombre de voitures ont des moteurs turbo. Pour cette raison, le terme "réparation de pneus" est susceptible d'être utilisé dans un plus grand nombre de pages qui parlent de la réparation automobile.
C'est exactement ce que le rapport TF-IDF dans l'audit du site Web sera en mesure de capturer !
