TF-IDF
TF-IDF stands for Term Frequency-Inverse Document Frequency. It's a way to measure how important a word is in a specific page compared to all other pages.
Term Frequency (TF): How often a word appears in a page.
Inverse Document Frequency (IDF): How rare or unique that word is across many pages.
In SEO, TF-IDF helps decide which words to focus on for content optimization. It helps you understand if a keyword is overused or underused compared to other websites.
Example:
If the word "SEO" appears many times on a page (high TF), but it's common on many sites (low IDF), the word might not stand out.
If a unique keyword like "SEO tool" appears often on your page, and not much on other sites, it could be a strong focus word for that page.
Using TF-IDF, you can optimize content by balancing common and rare words for better search rankings.
