What SEO Review Tools' Keyword Density Checker Offers
SEO Review Tools is a well-regarded free SEO tool suite with clean interfaces and accurate data. The keyword density checker shows single-keyword and multi-word phrase frequencies, filters stop words, and presents results in a sortable table. It's one of the more thoughtfully designed free density tools available.
For users who don't mind creating a free account, SEO Review Tools unlocks additional features like saved reports and higher usage limits. The core density functionality is accessible without login.
The Account Requirement
SEO Review Tools uses a freemium model — basic access is free, but some features and usage beyond certain limits require a free account. Creating an account requires an email address and opt-in to their mailing list.
For occasional keyword density checks, the free tier is usually sufficient. But if you prefer not to create accounts or share your email with SEO tool providers, that's a friction point that doesn't exist with a paste-and-analyze tool.

When to Use SEO Review Tools vs the Alternative

Open Free Keyword Density AnalyzerFrequently Asked Questions
Is SEO Review Tools the same as SE Ranking?
No — SEO Review Tools (seoreviewtools.com) is a free tool suite by Duy Nguyen. SE Ranking is a separate paid SEO platform. Both have keyword analysis features but are entirely different products.
Does SEO Review Tools' free account have usage limits?
Yes — the free tier has daily usage limits that reset every 24 hours. Creating a free account typically increases those limits. The paid tier removes limits entirely. The paste-based alternative here has no usage limits.
Which tool is more accurate?
Both tools calculate density using the same fundamental method: frequency divided by total words. Accuracy differences typically come from how each tool handles stop word filtering and text parsing, not from the underlying math.
