What is a keyword density checker?

A keyword density checker counts how often meaningful terms appear in a piece of text and expresses each count as a percentage of the total words. It is a quick way to spot the main topics a page emphasizes.

This free checker also accepts pasted HTML and strips tags before analysis, so you can inspect an article, landing page, or scraped document without manually cleaning the source first. Common stop words are omitted so the ranking focuses on descriptive terms.

Density is a diagnostic, not an SEO score. Search engines use context, intent, links, page quality, and many other signals, so natural writing matters more than forcing a number.

How to read keyword density results

Step 1

Paste content

Use visible text or HTML source from one page. The checker removes markup and normalizes capitalization.

Step 2

Review the ranking

Compare counts and percentages to see which terms are repeated most often. A high count may reflect the page topic or unnecessary repetition.

Step 3

Edit with context

Check whether repeated terms sound natural, support the page intent, and match the headings and metadata before making changes.

Common use cases

  • Compare a draft with a competing page’s visible copy.
  • Find repeated terms in product, category, or blog content.
  • Review text collected during a web scraping workflow.
  • Spot topic drift before publishing an SEO landing page.

Keyword density checker FAQ

What is a good keyword density for SEO?
There is no universal ideal percentage. Write for the reader, cover the topic clearly, and use the report to spot unnatural repetition rather than chase a fixed density.
Can I check keyword density from HTML source?
Yes. Paste HTML into the tool and it removes tags before counting readable text. Scripts, styles, and markup do not become keyword results.
Does this free keyword density checker analyze a URL?
This version analyzes content you paste locally in your browser. Use the Meta Tag Checker or Structured Data Extractor to inspect live page elements by URL.
Why are common words missing from the keyword report?
Very common stop words such as “the,” “and,” and “of” are excluded so the ranking highlights more descriptive terms.
What does keyword density percentage mean?
A term’s density is its occurrence count divided by the total extracted word count, multiplied by 100. For example, 4 occurrences in 200 words equals 2%.
Can keyword density guarantee better rankings?
No. Density is only a content comparison signal. Relevance, usefulness, page experience, technical accessibility, and overall site context also matter.
