Analyze term usage for SEO and content optimization

Tip: For best results, paste clean text without HTML tags. Keyword density between 1-2% is optimal for most e-commerce content.

How to Use This Tool

Follow these steps to calculate keyword density for your business content:

  1. Paste your content (product descriptions, blog posts, ad copy, or landing page text) into the content text area.
  2. Select your analysis type: choose Analyze Specific Keywords to check custom terms, or Find Top Keywords to see the most frequent words in your content.
  3. If analyzing specific keywords, enter comma-separated terms in the target keywords field (e.g. organic coffee, fair trade, single origin).
  4. Choose your preferred density format: percentage (e.g. 2.5%) or ratio (e.g. 1:40).
  5. Click the Calculate Density button to view your results.
  6. Use the Copy Results button to save your analysis, or Reset to clear all fields and start over.

Formula and Logic

Keyword density measures how frequently a target term appears relative to the total word count of a text. The tool uses two core calculations depending on your selected format:

  • Percentage format: (Number of keyword occurrences / Total words) * 100
  • Ratio format: Total words / Number of keyword occurrences (formatted as 1:X)

For top keyword analysis, the tool first counts all word frequencies in the content, sorts terms by occurrence count in descending order, and returns the top 10 most frequent words. All word counting is case-insensitive and ignores punctuation, numbers, and special characters.

Practical Notes

Keyword density is a key metric for e-commerce sellers, marketers, and content creators optimizing for search engines. Keep these business-specific tips in mind:

  • Aim for a keyword density of 1-2% for product descriptions and blog posts: higher densities may trigger search engine spam filters, while lower densities may hurt ranking relevance.
  • For paid ad copy (Google Ads, Facebook Ads), keep keyword density lower (0.5-1%) to prioritize readability and click-through rates over search optimization.
  • When analyzing competitor content, use the Find Top Keywords feature to identify high-performing terms they target, then adjust your own content strategy accordingly.
  • Always paste clean text without HTML tags, formatting, or special characters for the most accurate results.

Frequently Asked Questions

What is a good keyword density for e-commerce product descriptions?

Most e-commerce platforms and search engines recommend a keyword density of 1-2% for product descriptions. This balances search relevance with natural readability for customers. Avoid densities above 3% to prevent penalties for keyword stuffing.

Does this tool count keywords in alt text or HTML tags?

No, the tool only analyzes plain text pasted into the content field. It strips all HTML tags, punctuation, and special characters before counting words, so only visible text content is included in the analysis.

Can I analyze multiple keywords at once?

Yes, enter comma-separated keywords in the target keywords field when using the Analyze Specific Keywords option. The tool will return individual density data for each term you enter, up to 20 keywords per analysis.

Additional Guidance

For best results, pair this tool with other content optimization practices:

  • Use keyword density data alongside search volume metrics to prioritize high-value terms for your niche.
  • Test different keyword densities for your content and track ranking changes over time to find the optimal range for your industry.
  • Remember that keyword density is just one of many SEO factors: prioritize high-quality, useful content for customers over hitting exact density targets.
  • For multilingual content, run separate analyses for each language to account for different word structures and counting rules.
