Frequently Asked Questions
What is keyword density and why does it matter?
+
Keyword density is the percentage of times a specific keyword or phrase appears in a piece of content relative to the total word count. While Google no longer relies heavily on exact keyword density, keeping important keywords in a natural range (roughly 1%–3%) helps search engines understand your content's topic without triggering keyword stuffing penalties.
What is an ideal keyword density for SEO?
+
There is no single perfect density. Most SEO practitioners recommend 1%–2% for a primary keyword. Going above 3%–4% for a single keyword can appear spammy. Focus on natural usage and semantic variations rather than hitting an exact percentage. Google's algorithms are sophisticated enough to understand context, not just exact repetition.
Why are stop words excluded from the 1-word results?
+
Stop words are extremely common words like 'the', 'is', 'a', 'and' that occur so frequently they don't carry meaningful information about your content's topic. Excluding them reveals the words that actually define your content, making the keyword density analysis much more actionable for SEO purposes.
Why do the 2-word and 3-word tabs include stop words?
+
Multi-word phrases often need stop words to be grammatically complete and meaningful. For example, 'how to write' is a meaningful 3-word phrase that contains the stop word 'to'. Filtering stop words out of multi-word phrases would eliminate many real long-tail keywords. The 2-word and 3-word tabs show all phrase combinations so you can identify natural long-tail keywords.
How many words should my page have for good SEO?
+
This depends on the content type and competition level. Informational articles and blog posts tend to rank well with 1,200–2,500 words. In-depth guides and pillar pages often exceed 3,000 words. Short product pages can rank effectively at 300–500 words. Use the Word Counter tool to check your current length and make sure your primary keywords appear frequently enough to signal relevance.
