Enter 1 or more domains and a keyword to analyse, then click Check Keyword Density
Keywords used to be the #1 factor in search engine ranking, but due to the overuse ("keyword stuffing"), search engines give them less priority today. However good keyword density is still important to achieving good SEO. Our tool's ability to compare multiple sites is also highly useful.
A keyword density between 3% and 10% of the total word count is a good density for search engines to effectively find and rank your content. This is why using a Keyword Density Tool, such as KeywordDensityChecker.com's free online application is extremely helpful.
The Keyword Density tool is primarily intended to examine whether a search engine can easily correlate which search terms would be most relevant for a page.
If the intended main phrase or keyword(s), found in the main title and meta data tags, are not detected to be occurring among the top phrases / or body content of the page there is a disconnect.
For that reason, the search engine will determine there is little correlation between the key search term and the content and therefore not rank this page high in order to prevent this irrelevant material to be returned to a user searching this term.
When Keyword optimizing pages, it is recommended that the top keywords occur in as many elements as possible, H1-H6, (title, heading, bold text, link text etc). It is also recommended that the targeted phrases and keywords accurately represent the content AND they be among the phrases with the highest density, within the content on that page.
The actual density of keywords should ultimately be governed by the content and style of a well written page. However it is important to note that the targeted phrases and keywords should be among the phrases with a density of 3% to 10% of the total word count of any given page. Meaning too few is not helpful and too many raises a red flag.
Whether other pages and sites use the targeted phrase/keyword to link to the page is also important of course but that is outside of the scope of the Keyword Density Analyzer. It may be worth it to checkout WebPageLinkAnalyzer.com to examine keywords and linking.
