Free CheckSERP Keyword Density Tool Alternative
- CheckSERP offers a keyword density checker as part of its SERP and SEO tool suite
- Like most URL-based tools, it requires a live page — can't analyze unpublished drafts
- Free paste-based alternative: instant density results on any text without a URL
- Both tools are free; the difference is input method (URL vs paste)
Table of Contents
CheckSERP's keyword density tool analyzes live pages by URL — useful for checking published content and auditing competitor pages. For draft content that doesn't have a URL yet, a paste-based alternative works faster: copy your text, paste it above, and get density results in under a second.
CheckSERP's Keyword Density Checker
CheckSERP is a suite of free SEO tools focused on SERP analysis, rank tracking, and on-page optimization checks. The keyword density tool fits into that broader on-page audit workflow — enter a URL and it returns a frequency table of the words and phrases on that page.
It's particularly useful when you want to analyze a competitor's published page as part of a SERP audit — seeing exactly what keyword mix a top-ranking page uses.

URL-based analysis is great for competitive research — you can analyze any publicly accessible page with no copy-paste effort. But there are important cases it doesn't cover:
- Pre-publish checking: Content in draft needs density review before it goes live, not after.
- URL-less content: Email copy, sales scripts, ad copy, and social posts don't have URLs to analyze.
- Clean content analysis: URL crawlers include navigation text, footers, and sidebars in the word count. Pasting body text only gives you a cleaner density calculation for the actual content.
How the Paste-Based Alternative Works
- Copy your content from wherever you're writing it — Google Docs, your CMS, a text file.
- Paste it into the tool above.
- Click Analyze.
Results show single-word density, 2-word phrase density, and 3-word phrase density — all in one pass. No URL. No crawl delay. No published page required.
Check Keyword Density on Draft Text
Paste your content for instant density results — no URL required, no crawl wait, no account.
Open Free Keyword Density AnalyzerFrequently Asked Questions
Is CheckSERP free?
CheckSERP offers a free tier with access to core tools. Some features require a paid plan. The keyword density tool is accessible on the free tier.
Can I use CheckSERP to analyze competitor pages?
Yes — URL-based tools like CheckSERP are well-suited for competitor page analysis. Enter any publicly accessible URL to see its keyword density profile. For your own draft content, paste-based analysis is more practical.
Does the paste-based tool account for page structure (headings vs body text)?
The paste-based tool analyzes whatever text you give it. If you paste your full page content including headings, those keywords are counted alongside body text. For structure-aware analysis, you can paste just the body text or just the headings separately and compare.
