Question 1

What is keyword density?

Accepted Answer

Keyword density is the percentage of times a keyword or phrase appears on a page compared to the total number of words. For example, if your page has 1,000 words and your target keyword appears 15 times, the keyword density is 1.5%. It helps search engines understand what your content is about, but over-using keywords (keyword stuffing) can result in penalties.

Question 2

What is the ideal keyword density for SEO?

Accepted Answer

There is no single "ideal" keyword density, but most SEO experts recommend keeping primary keywords between 1-2% density. Google does not use a specific keyword density threshold, but their algorithm (including the helpful content update) can detect unnatural keyword usage. Focus on writing naturally for humans, using synonyms and related terms, rather than hitting a specific percentage.

Question 3

What is keyword stuffing and how does Google penalise it?

Accepted Answer

Keyword stuffing is the practice of overloading a page with keywords in an attempt to manipulate search rankings. This includes repeating the same keyword excessively, using hidden text, or inserting irrelevant keywords. Google explicitly lists keyword stuffing as a webspam technique that can result in a manual action (penalty) or algorithmic demotion. Their internal "KeywordStuffingScore" ranges from 0 (none) to 127 (maximum stuffing).

Question 4

How do I use a keyword density checker?

Accepted Answer

Enter a URL or paste your content into the tool. It will analyse all the text and show you the most frequently used single words, two-word phrases, and three-word phrases along with their density percentages. Look for keywords with density above 3% (over-optimised) and ensure your target keywords appear at a healthy 1-2% density.

Question 5

Does keyword density still matter in 2026?

Accepted Answer

While keyword density is not a direct ranking factor, it remains a useful diagnostic tool. Google uses semantic understanding (BERT, MUM) to understand content, so exact keyword matching is less important than topical relevance. However, keyword density analysis helps you: 1) Ensure your target keyword appears enough times, 2) Detect accidental keyword stuffing, 3) Discover what keywords competitors prioritise, 4) Find content gaps and opportunities.

Question 6

What is the difference between keyword density and TF-IDF?

Accepted Answer

Keyword density is a simple percentage of how often a word appears on one page. TF-IDF (Term Frequency-Inverse Document Frequency) is more sophisticated — it measures how important a word is to a document relative to a collection of documents. TF-IDF gives higher scores to words that are common on your page but rare across the web, making it better for identifying truly distinctive keywords.

Question 7

Can I analyse competitor pages with this tool?

Accepted Answer

Yes! Enter any public URL to see which keywords and phrases they use most frequently. This is one of the most powerful uses of a keyword density checker — you can discover what keywords your competitors are targeting, how they structure their content, and find gaps in their strategy that you can exploit.

Question 8

How many words should my page have for good SEO?

Accepted Answer

There is no magic word count for SEO. The ideal length depends on the topic, search intent, and competition. However, studies show that top-ranking pages average 1,400-2,000 words for informational queries. More important than length is comprehensiveness — does your content thoroughly answer the search query? Our tool shows your total word count alongside keyword density to help you evaluate content depth.
