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-Only vs Paste-Based — What's the Practical Difference?

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:

How the Paste-Based Alternative Works

  1. Copy your content from wherever you're writing it — Google Docs, your CMS, a text file.
  2. Paste it into the tool above.
  3. 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.

Frequently 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.
