Did you know that the percentage of times a keyword appears on your web page in relation to the total number of words on that page can affect the page's ranking?
Yes, and it's called "Keyword Density."
If you use a keyword or phrase too frequently, search engines will likely penalize your site. If you do too little, search engines may not pick up on enough signals to rank the page for that specific keyword.
Simply put, for the best search performance, you should optimize your keyword density. Neither too much nor too little.
But how do you begin calculating the number of times a keyword appears on a web page or blog post? Are you even capable of doing it correctly?
It turns out you'll need the assistance of a reliable tool. That is why we created the Keyword Density Checker in this SST.
Keyword Density Checker is a tool designed specifically to calculate the keyword density of any web page.
This tool is ideal for resolving that issue. It lets you analyze a whole web page by using its URL or a piece of text by copying and pasting.
The most basic way to calculate keyword density is to divide the number of times a specific keyword appears in a text by the total number of words in the text, then multiply the result by one hundred to get your percentage.
Our Keyword Density tool, however, does more than just calculate keyword density. It actually searches for and analyzes ALL of the top keywords used on the page or text under consideration, and displays the following metrics for improved SEO performance and effective content optimization:
Top keywords used in the content, frequency counts, and indicators indicating whether the keywords have a title, description, or H*>.
Keyword density for each keyword or phrase used in the examined content, including frequency and percentage usage. These calculations are broken down into descending tilts of one-word, two-word, three-word, and four-word keywords.
This type of advanced analysis enables you to easily define and become acquainted with the proportion and sum of keywords used in your content.
