Frequently Asked Questions

Keyword density is the percentage of times a keyword appears relative to the total word count. For example, if a keyword appears 3 times in a 100-word text, its density is 3%.

There is no perfect keyword density. Generally, 1-3% is considered natural. Above 3% may be seen as keyword stuffing by search engines. Focus on writing naturally rather than hitting a specific number.

Keyword prominence measures how important a keyword is based on where it appears. Keywords in the title tag, H1, and H2 headings carry more weight than those only in body text.

The Flesch Reading Ease score rates text on a 0-100 scale. Higher scores mean easier to read. Scores of 60-70 are considered standard. The grade level indicates the US school grade needed to understand the text.
