Frequently asked questions

What is an ideal keyword density for SEO?

There is no universally agreed ideal. A density of 1 to 2 percent for a primary keyword is commonly cited, but natural, readable writing is more important than hitting a specific percentage.

Does it analyse single words only or also phrases?

Both single words and multi-word phrases are analysed, with results shown for the most frequent occurrences.

Are common words like "the" and "and" included?

Common stop words are typically filtered out of the results so you can focus on meaningful keywords.
