Tf_IDF also known as term frequency-inverse document frequency. In SEO
, tf_idf help to find synonyms of all-important keywords which are mostly used in documents and then apply tf_idf on those words in the document.
We first compute the “bag of words
” of the given landing page
After that we pick top 10 search terms which have the highest weight in corpus (Frequency)
Then we find tf_idf terms of landing page and competitor page
Then filter only those terms which are not present in landing page.
