Inspect 1-Word Keywords

Review the single-word table to verify that your primary thematic nouns and industry verbs appear consistently without dominating the page.

Frequently Asked Questions

What is an ideal keyword density percentage for SEO?▼
Most SEO experts recommend maintaining a primary keyword density between 1.0% and 2.5%. Exceeding 3.0% to 3.5% risks triggering search engine keyword-stuffing filters.
What is an n-gram in content analysis?▼
An n-gram is a contiguous sequence of *n* words from a given text. A 1-gram is a single word ("calculator"), a 2-gram (bigram) is a two-word phrase ("mortgage calculator"), and a 3-gram (trigram) is a three-word phrase ("home loan calculator").
What are stop words?▼
Stop words are common grammatical words (such as *the, is, at, which, on, and*) that search engines typically ignore when indexing core topical meaning. Filtering them out isolates genuine semantic keywords.
Does Google still care about keyword density?▼
Google does not use a rigid keyword density quota to rank pages. However, Google does use advanced systems to detect unnatural keyword stuffing. Monitoring density ensures your content remains natural, balanced, and readable.
Is my private text draft stored or monitored on ToolMela?▼
No. All text parsing, frequency calculation, and n-gram extraction take place entirely within your browser using client-side JavaScript. Your text is never transmitted to or saved on any remote server.
Can I analyze text in languages other than English?▼
Yes. The analyzer tokenizes text in any language using standard Unicode word boundaries. However, the automated stop-word dictionary is optimized for English; non-English stop words can be filtered using the custom filter field.
