How the keyword density checker works.

This tool fetches the public HTML for a page, extracts visible text, removes common stop words, and calculates top keyword usage.

01

Enter a page URL

Type a domain or page URL. The checker validates safe HTTP and HTTPS URLs before scanning.

02

Analyze visible text

The tool measures word count, top keywords, density percentages, title usage, description usage, headings, and optional focus keyword placement.

03

Review keyword usage

Use the report to catch missing focus keywords, unnatural repetition, thin content, or keyword targeting that does not match the page topic.

Common keyword density issues this tool can reveal.

Keyword density issues can reveal missing topic signals, keyword stuffing, weak title alignment, or content that does not clearly match its target topic.

TTL

Missing focus keyword

If your target keyword never appears in the visible text, the page may not clearly target that topic.

DES

Keyword stuffing

Repeating a keyword too often can make content feel spammy and unnatural.

CAN

Weak title alignment

Important keywords should usually appear naturally in the title, description, headings, or body when relevant.
