Built Keyword Density Analyzer to help balance content optimization—would love your feedback!

Hey Product Hunt community! 👋

When writing or optimizing articles for search engines, striking the right balance with term frequency is essential. Overusing target keywords can lead to search engine penalties, while underusing them might make it harder for algorithms to grasp the main topic.

To help maintain natural phrasing while keeping key terms balanced, I vibe-coded a fast, browser-based Keyword Density Analyzer micro-tool.

Key features & capabilities:

• Real-time Term Frequency Analysis: Instantly calculates single-word and multi-word phrase frequencies along with their percentage ratios.

• Over-Optimization Detection: Helps content creators and SEOs quickly spot repetitive keywords before publishing.

• Instant & Privacy-Focused: Processes text 100% client-side with clean JavaScript to ensure fast execution and data privacy.

I built this lightweight utility using PHP and vanilla JS to streamline daily content auditing workflows. You can test it out directly here: Online Keyword Density Analyzer

Question for SEOs & content creators: How do you usually monitor keyword distribution in your writing workflow? Are there any specific metrics or n-gram analysis features you find most helpful when fine
