How to Extract Keywords From Text
Heshan Fernando
Co-founder & COO
You have a draft article, landing page, transcript, or research note and want to know what it is really about. A plain word count can help, but it often surfaces common words or fragments. Key phrases usually tell the story better.
A keyword extractor pulls likely key phrases from text and shows them next to a plain word count so you can see the difference between frequency and meaning.
What keyword extraction involves
Keyword extraction tries to identify important phrases in a body of text. RAKE, short for Rapid Automatic Keyword Extraction, looks for candidate phrases and scores them based on word patterns and frequency.
This differs from a simple word frequency count. Word counts show repeated individual words. Key phrase extraction tries to surface phrases that carry topic meaning.
Why people get stuck here
Writers often assume the topic they intended is the topic the draft communicates. Extracted phrases can reveal whether the text actually emphasizes the right ideas.
The danger is over-optimizing. A keyword extractor can guide revision, but it should not make the writing robotic.
| Method | Shows | Limitation |
|---|---|---|
| Word count | Repeated words | Misses phrase meaning |
| RAKE phrases | Topic-like phrases | Needs human review |
| Manual scan | Context | Can be biased |
| SEO review | Search alignment | Should not override clarity |
What a good keyword review looks like
Phrases match the draft’s purpose
If the extracted phrases point to a side topic, the draft may need clearer focus.
Frequency is not worshiped
The most repeated term is not always the best keyword. Context matters.
Revision stays natural
Use the findings to clarify headings, intros, and coverage. Do not stuff phrases into every paragraph.
Common mistakes to avoid
- Treating extracted keywords as a mandatory SEO checklist.
- Ignoring key phrases that reveal a mismatch in the draft.
- Removing natural language to force exact phrases.
- Comparing unrelated drafts by raw keyword count alone.
- Forgetting that phrase extraction still needs human judgment.

Frequently asked questions
What is RAKE?
RAKE means Rapid Automatic Keyword Extraction. It is an algorithm for identifying likely key phrases in text.
Is keyword extraction the same as SEO research?
No. It analyzes your text. SEO research also needs search demand, competition, intent, and audience context.
Why compare phrases with word counts?
Word counts show repetition, while phrases often show meaning. Comparing both gives a better view of the draft.
Final thought
Extract keywords to see what your text emphasizes. Then use that view to sharpen the writing, not to flatten it into keyword paste.
