Free WebFX Keyword Density Checker Alternative
- WebFX's keyword density tool is URL-based — it crawls a live page to calculate density
- Limitation: can't analyze draft content before it's published
- Free alternative: paste text directly — works on drafts, emails, product descriptions, any content
- Both tools are free and produce accurate density percentages

WebFX's keyword density checker crawls a URL and returns density data for the published page. It's accurate and free, but it requires a live URL — which means you can't use it on draft content before publishing. A paste-based alternative solves that: paste any text, get density results instantly, no published page required.
How WebFX's Keyword Density Checker Works
WebFX's tool takes a URL as input, fetches the page, and calculates keyword density based on the rendered content. It's a straightforward URL analyzer — enter a domain or page URL, click check, and get a density table.
WebFX is a well-known digital marketing agency and their free tools are legitimate and widely used. The keyword density checker is accurate for analyzing published pages — particularly useful for competitive analysis of live competitor URLs.
The URL-Only Limitation
Because WebFX's tool requires a live URL, there are several scenarios where it can't help:
- Draft content: Content in your CMS draft, Google Docs, or Word file isn't accessible by URL until it's published.
- Email copy: Marketing emails, cold outreach, and newsletter drafts don't have URLs.
- Product descriptions: Descriptions being written before a product is live don't exist at a public URL.
- Staging environments: Content on a password-protected staging server can't be crawled.
For any of these cases, a paste-based tool is the only practical option.

- Draft text: Write your content, paste it in, check density before you hit publish.
- Any content type: Blog posts, landing pages, product copy, email campaigns, ad copy — if you can paste it, you can analyze it.
- Phrase density: Bigrams (2-word) and trigrams (3-word) analyzed alongside single keywords.
- No crawl delay: Results appear in under a second vs waiting for a URL fetch.
WebFX vs Paste-Based Tool — When to Use Each
- Use WebFX when: You want to analyze a competitor's live page, audit an already-published post, or check what Google is actually crawling on a page (including dynamic content).
- Use the paste alternative when: You're writing or editing content, working with draft material, or analyzing any text that isn't available at a public URL.
Analyze Draft Text Without a URL
Paste your content above and get instant keyword density results — no URL, no published page needed.
Open Free Keyword Density AnalyzerFrequently Asked Questions
Does WebFX's tool require a login or API key?
No — WebFX's keyword density checker is free and publicly accessible without an account. It's a straightforward URL entry form.
Can WebFX's tool check a password-protected page?
No — the tool crawls public URLs only. Any page requiring authentication, including staging environments and CMS previews, can't be accessed by the tool. Paste-based analysis is the only option for those.
Does the paste-based tool show the same density numbers as a URL-based tool?
Yes, for the same text content. The difference is that URL-based tools may include boilerplate text (navigation, footer, sidebars) in the word count, which can dilute density numbers. Paste-based analysis lets you control exactly what text is included.
