Keyword Density Checker – Professional On‑Page SEO Analysis Tool
The Keyword Density Checker plugin is a practical on‑page SEO tool designed to help writers, SEOs and digital marketers understand how keywords are distributed across their content. By combining a clean interface with accurate word and phrase frequency analysis, it brings clarity to optimisation decisions without encouraging keyword stuffing or over‑engineering.
What the Keyword Density Checker Does
This keyword density tool parses any text or HTML you paste, strips out markup and focuses on the visible words. It then calculates total word count, filtered word count and the number of unique terms, providing an instant snapshot of how your content is composed. You can enter target keywords or phrases, and the checker will report their exact counts, density percentages and a simple status indicator ranging from “Not present” to “Very high – risk of keyword stuffing”.
Features for SEO‑Friendly Content Optimisation
Flexible filtering and phrase analysis
The Keyword Density Checker supports exclusion of common English stop words (such as “the”, “and” or “of”) and lets you set a minimum word length, ensuring short or unimportant tokens do not skew your analysis. Beyond single‑word frequency, it automatically surfaces the most common 2–3 word phrases, revealing natural keyphrases like “keyword density checker” or “on‑page SEO” that may deserve special attention in headings or internal links.
History, export and shareable analysis
Each analysis can be saved to a local history, allowing you to revisit previous checks without re‑pasting content. A structured export summary includes word counts, keyword densities and top terms, ready to copy into client reports or editorial briefs. Shareable links encode the content and settings in the URL, making it easy to send a fully reproducible keyword density analysis to colleagues or clients while keeping calculations consistent.
