Density Checker: Content Optimization Glitch?

Hey everyone,

We just rolled out our shiny new 'Keyword Density & Frequency Checker' tool. The idea was simple: give users a straightforward resource to fine-tune their on-page SEO and improve their content optimization efforts. You know, make life easier for everyone trying to rank.

But here's the kicker: it seems to have a mind of its own. We're noticing some really bizarre results, especially for common, high-volume keywords. Picture this: a keyword is clearly present multiple times in the text, yet the tool occasionally reports extremely low or even zero density. It's almost like it's getting confused or over-analyzing something simple, and frankly, it's driving us a bit nuts. This is particularly frustrating when users are trying to verify their content optimization strategies and get accurate feedback.

So, has anyone else experienced their keyword analysis tools acting a bit... temperamental? Any common pitfalls or troubleshooting steps I should consider beyond the obvious "check the code again" mantra? Anyone faced this before?
