Keyword Frequency Checker (Word Occurrence & Phrase Counter)

What Is Keyword Frequency and How Does It Differ From Keyword Density?

Keyword frequency is the absolute raw count of how many times a particular word or phrase occurs within a piece of text (e.g., '12 occurrences'), whereas keyword density is the relative percentage of that count against total words. Monitoring raw keyword frequency helps copywriters ensure consistent keyword placement across introductions, body headings, and conclusions.

Frequently Asked Questions

What is keyword frequency?

Keyword frequency is the total number of times a specific keyword or phrase appears within a given piece of written content.

What is the difference between keyword frequency and keyword density?

Keyword frequency is an absolute integer count (e.g., the phrase appears 8 times), while keyword density is a relative percentage (e.g., the phrase makes up 1.6% of a 500-word article).

Where is it most important to place primary keywords in an article?

Primary keywords should ideally appear in the title tag, H1 heading, the first 100 words of the introduction, at least one H2 subheading, the conclusion, and the image alt text.

How does Term Frequency-Inverse Document Frequency (TF-IDF) relate to frequency?

TF-IDF is a statistical formula that measures how important a word is to a document relative to a broader corpus, balancing common term frequency against informational uniqueness.

Can I check multi-word phrase frequency with this tool?

Yes. The tool analyzes 1-word, 2-word, and 3-word phrase frequencies simultaneously with automatic stop-word toggling.

How can I use frequency analysis to avoid over-optimization?

If a specific 2-word or 3-word phrase appears dozens of times in a short article, the frequency counter will highlight it so you can introduce natural variations.

Does the frequency counter handle uppercase and lowercase text identically?

Yes. The tool normalizes all words to lowercase during analysis so capitalized terms at the start of sentences are counted accurately together.
