Why Check Keyword Density?

Understanding Keyword Density in Modern SEO

Keyword density refers to the percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page. In the early days of Search Engine Optimization (SEO), webmasters would "stuff" keywords to rank higher. Today, search algorithms are much smarter.

What is the Ideal Keyword Density?

There is no single "perfect" number, but most SEO experts agree that a keyword density between 1% and 2% is ideal. If your main keyword appears more than 3% or 4% of the time, it may trigger spam filters. Conversely, if it appears less than 0.5%, search engines might not understand that your page is authoritative on that topic.

LSI Keywords and Semantic Search

Modern SEO isn't just about repeating one word. It's about context. This tool helps you identify your primary keywords, but you should also look for related terms (LSI keywords). If you are writing about "Apple" (the brand), your text should naturally contain words like "iPhone," "Mac," "Technology," and "iOS." Our density checker helps you visualize the semantic map of your content.

How to Fix High Keyword Density

If this tool shows a density higher than 3% for your target term, try using synonyms. For example, instead of repeating "best running shoes," use "top jogging footwear," "athletic sneakers," or simply "shoes." This improves readability for humans and relevance for search engines.

Frequently Asked Questions (FAQs)

Does it check for 2-word or 3-word phrases? +

What are "stop words"? +
Stop words are common words like "the," "is," "at," "which," and "on." They don't carry significant meaning for SEO, so we exclude them by default to show you the keywords that actually matter.

Does keyword density still matter for SEO? +
Yes, but not as a raw ranking factor. It matters for "topical relevance." It ensures search engines understand what your page is about without viewing it as spammy.
