Is my data safe and private?

What is keyword density in SEO?
Keyword density is the percentage of times a specific keyword or phrase appears on a web page compared to the total number of words on that page. It is a core parameter in content optimization.
What is the optimal keyword density?
There is no official 'perfect' percentage, but most SEO experts recommend keeping keyword density between 1% and 2% for your primary term. This ensures optimization without looking spammy.
What is keyword stuffing?
Keyword stuffing is the practice of loading a webpage with keywords in an attempt to manipulate search engine rankings. Google penalizes websites that stuff keywords because it creates a poor user experience.
What are N-Grams?
N-Grams represent contiguous sequences of words. A 1-Gram is a single word, a 2-Gram represents a two-word phrase, and a 3-Gram represents a three-word phrase. They reveal semantic structure.
Does this tool work completely offline?
