You’ve got a page that isn’t ranking, and you’re not sure why. It’s not always about backlinks or content length — sometimes your own words are working against you.
Overusing the same keywords kills readability and triggers spam filters. The real issue is that you don’t know how often you’re repeating phrases — until now.
What Is a Keyword Density Analyzer?
Keyword Density Analyzer is a free browser-based tool that checks how often specific words or phrases appear in your content. You paste a URL or raw text, and it calculates frequency, density, and pulls out the most-used phrases in seconds.
It shows you over-optimized terms so you can fix them before Google flags your page.
Why It Matters for SEO
Google recrawls most sites every 3-7 days. If your content looks spammy, you’ll lose ranking fast.
Over-optimized pages get downgraded, not banned — but the drop is enough to kill traffic. Pages with keyword density above 3% are 57% more likely to rank below page 1. Most people miss this because standard SEO tools don’t show raw density.
Here’s what actually happens: you write naturally, tweak for keywords, then tweak again — and suddenly one word appears 18 times in 500 words. That’s a 3.6% density. That’s dangerous.
How to Use It
- Go to https://scrawl.tools/tools/keyword-density (no login needed)
- Paste any public URL or your article text into the box
- Click “Analyze” — results appear in under 10 seconds
It’s free. No account required. You can run 10 checks in a row without hitting a paywall.
What the Results Tell You
The tool shows total word count, keyword frequency, and percentage density. It lists every phrase used 3+ times and ranks them by repetition.
You’ll see if “best running shoes” appears 12 times in 600 words — that’s 2%, which is acceptable — but if “buy buy buy” hits 9 times, that’s a red flag.
The over-optimization warning triggers when any keyword hits over 3% density. That’s the zone where Google starts questioning intent.
It’s not about chasing a perfect number — it’s about catching what you didn’t notice.
3 Mistakes Most People Make
- They write first, check density later — by then, edits feel forced. You should check after draft, not after publishing.
- They ignore phrase patterns — you don’t just overuse “SEO tools,” you repeat “best free SEO tools 2025” 6 times. The tool catches full phrases, not just single words. Most people miss that.
- They think density is the only metric — it’s not. Combine this with Core Web Vitals Checker to ensure speed and quality aren’t dragging you down. A fast page with stuffed keywords still fails.
You’re not writing for robots. But if your content trips spam filters, real people won’t see it. Use the tool before every publish — it takes less time than making coffee.
