Frequently Asked Questions
What is a good keyword density for SEO?
As a general rule, keeping your main keywords between 1% and 3% of your total word count is the sweet spot for search engines. This live tracker automatically counts your words as you type, making it simple to keep your content balanced, natural, and safe from spam filters.
How does the Flesch-Kincaid readability checker work?
Our built-in readability tracker scoring system checks how easy your writing is to read. It automatically looks at your sentence length and word choices to give your draft an instant grade-level score. Making your content simpler to read doesn't just keep your audience engaged—it also helps your page look much better to search engines like Google.
Can this tool detect keyword stuffing automatically?
Yes. If you repeat any single word or phrase too much—specifically over 3.5% of your total text—the breakdown table will flag it. This warning lets you know that it's time to ease up, keeping your article safe from search engine spam penalties that can hurt your rankings.
Why should I check the primary keyword in my Title or H1 tag?
Search engines pay much closer attention to keywords placed inside your main headlines than they do to normal paragraph text. This check simply confirms that your target keyword shows up right inside your main H1 title tag, making it instantly clear to search bots what your page is about.
Is my pasted text processed securely or stored?
Your writing stays secure. This layout operates completely client-side inside your local web browser engine using plain vanilla JavaScript modules. No text uploads, backend server transmissions, or personal logs ever occur during processing.
Write Content That Ranks Without Getting Penalized
Gone are the days of just stuffing keywords into a page and hoping for the best. Today, search engines look for articles that read naturally and actually help people. This tool looks under the hood of your text to fix what matters most:
- Keyword Density Tracker – Instantly see which words you repeat the most, so you know exactly what topics Google will associate with your page.
- Readability Score – Uses the Flesch-Kincaid scale to make sure your sentences aren't too long or confusing for your average reader.
- Title & H1 Matcher – Double-checks that your primary target keyword is right where it belongs: in your main headline.
- Spam Filters & Warnings – Flags over-optimized phrasing before it looks suspicious to search engines.
Drop your draft in for an instant health check. You'll get the exact tweaks your copy needs to satisfy search bots and real human readers before you go live.
