Below, we explain step-by-step how to use this tool and what each of its features does.
Step 1: Copy And Paste
First, fill in the “Paste your content” box with your written article or information.
If you would want, you can type manually here as well.
A word count will show up beneath the total amount of words in your text as you type or paste it.
Step 2: Inputting Keywords
“Enter focus keyword(s)” is the second box.
Enter the keywords that your content is aimed at here.
If you have multiple keywords, use a comma (,) to separate them.
For instance, global warming, sustainability, and climate change
Example:

After identifying these keywords, the program will show the density findings.
Step 3: Check Density Button
Now you just need to click one button “Check Density”
When you click this button, the tool will begin a thorough SEO audit of your content.
- You will get in a few seconds:
- Count of each keyword (number of times used)
- Density Percentage (ratio of the main keyword to the total words)
- SEO Suggestion (the tool will guide you if the keyword is low or high)
Step 4: Meaning of SEO Suggestion
There are differing views regarding acceptable levels because Google has never stated an optimal keyword density. Nonetheless, the majority of SEO specialists advise aiming for a target keyword density of 1-2%.
- Density is low, use a little more” if the keyword is less than 1%.
- If the keyword is more than 3%: “Don’t overdo keyword stuffing.”
- If it’s between 1% and 3%, “Perfect! Keyword density is good.”
- This feature is best for writers who want to maintain Google SEO optimization.
Step 5: Seeing the Score for Readability
The Readability Score of your content is automatically determined by the tool using the Flesch Reading Ease algorithm.
This shows how simple or complex your writing is to read.
Score Meaning:
- 0–30: Very hard (technical or academic style)
- 31–50: Hard
- 51–60: Fair
- 61–70: Standard (perfect balance)
- 71–80: Easy
- 81–100: Very easy and readable
This shows how easy or hard it is to read your written work.
Step 6: Highlighted Keywords
Below will appear a section “Highlighted Keywords in Content.”
The keywords you provided will be highlighted in blue, and your whole content will be shown below.
This allows you to visually see where keywords are used and whether they are evenly spread.
Step 7: Graph & Word Cloud
The tool automatically generates both Chart.js and Word Cloud:
- Bar Chart:
A bar chart displays the density of each keyword in percent.
This gives you an instant idea of which keywords are in balance and which are overused.
- Word Cloud:
A beautiful Word Cloud is created where the size of each word is based on its frequency.
Larger words = more frequent use.
Smaller words = less frequent use.
This makes it simple to determine which words have the greatest impact on your content.
Step 8: Export Options (PDF, CSV, Excel)
The tool doesn’t just analyze it also allows for report export!
You can export your results in three formats:
- PDF Report: A beautifully formatted report that includes content, keywords, and readability.
- CSV File: If you want to analyze in Excel or Google Sheets.
- Excel Report (.xls): A ready-to-open Excel sheet with all the data and a summary.
This option is especially useful for those who send SEO reports to clients.
