Frequently Asked Questions
01 What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears in your content compared to the total word count. For example, if your keyword appears 3 times in a 100-word article, the density is 3%. Tools Oasis calculates this automatically for any keyword you specify.
02 What is the recommended keyword density for SEO?
Most SEO experts recommend a keyword density of 1-3% for your primary keyword. Going below 1% may not signal relevance to search engines, while exceeding 3% can be seen as keyword stuffing and may hurt your rankings.
03 What are n-gram phrases?
N-grams are contiguous sequences of words. A 1-gram is a single word, a 2-gram (bigram) is two consecutive words like 'content marketing', and a 3-gram (trigram) is three words like 'search engine optimization'. Analyzing these helps you find important multi-word phrases in your content.
04 Is my content stored or sent anywhere?
No. All keyword analysis happens entirely in your browser using JavaScript. Tools Oasis never uploads, stores, or logs your content. It stays 100% on your device.
