Keyword Prominence Checker
Analyze where and how prominently your target keyword appears across your page content — title, H1, subheadings, opening paragraph, and body. Get a 0–100 prominence score with actionable recommendations.
How to Use the Keyword Prominence Checker
Enter your target keyword in the input field, then paste your page content — either as plain text or as raw HTML. The tool instantly analyzes where your keyword appears and produces a 0–100 prominence score with a detailed location breakdown and personalised recommendations.
Plain Text vs. HTML Input
If you paste plain text, the tool analyses positional prominence — checking the first 10%, body, and last 10% of your content. If you paste raw HTML (e.g. copied from your browser's 'View Source'), the tool additionally extracts your <title> tag and parses H1, H2, and H3 headings for a complete on-page analysis. HTML input is recommended for the most accurate results.
Understanding the Prominence Score
The score is built from six weighted checks: keyword in the title tag (+25 pts), in the H1 heading (+20 pts), in H2/H3 subheadings (+15 pts), in the first 10% of content (+20 pts), appearing at least 3 times (+10 pts), and density between 1–3% (+10 pts). A perfect 100 means your keyword is optimally placed across all key sections.
Acting on Recommendations
Each missing check generates a specific recommendation — for example, 'Add keyword to H1' or 'Move keyword earlier in content'. Address these one by one starting with the highest-weighted items (title and H1). After making changes, re-paste your updated content to verify your score improved.
Frequently Asked Questions
What is keyword prominence in SEO?
Keyword prominence refers to how early and how visibly a target keyword appears within the key structural elements of a page — including the title tag, H1 heading, opening paragraph, subheadings, and body content. Search engines use prominence as a relevance signal: a keyword in the first 10% of a page is treated as more indicative of the page's main topic than one buried deep in the footer. High prominence signals to Google that a page is directly focused on that keyword.
How is keyword prominence different from keyword density?
Keyword density measures how often a keyword appears as a percentage of the total word count. Keyword prominence measures where it appears. A page can have low density but very high prominence (keyword in title and H1 but mentioned only once). SEO best practice is to optimise both — aim for 1–3% density and ensure the keyword appears early and in structural elements like title, H1, and the opening paragraph.
Why does the first paragraph matter for keyword prominence?
The first paragraph (roughly the first 10% of visible content) carries significant weight for both search engines and users. Google's crawlers analyse early content to determine a page's primary topic quickly. Including your target keyword in the opening paragraph reinforces the relevance signal established by the title and H1. From a UX standpoint, it also immediately confirms to human readers that they've landed on the right page.
How should I optimise headings for keyword prominence?
Your H1 should contain the primary keyword or a very close variation — this is the single most important on-page heading signal. H2 and H3 subheadings should include the keyword or semantically related phrases at least once each. Avoid forcing exact-match keywords into every subheading; instead use natural variations that support topical depth.
Does keyword prominence apply to HTML pasted into the tool?
Yes. If you paste raw HTML, the tool automatically extracts the <title> tag content, parses H1/H2/H3 headings, and strips all tags to produce clean plain text for body analysis. This means you can copy your page's source code directly and get an accurate prominence analysis across all structural elements. For plain text input, the title and HTML-specific heading checks are skipped.
