Keyword Prominence Checker
Paste a page's HTML and the keyword you're targeting. The checker shows whether — and how early — the keyword appears in each place that signals a page's topic: title, description, H1, opening paragraph, subheadings, URL, image alt text and anchors.
How to use the Keyword Prominence Checker
Paste the page HTML
Page source is fine. Add the page URL so the slug can be checked.
Enter one keyword or phrase
The phrase you want this page to be found for.
Review each placement
Each row says whether the keyword was found and its position within that element.
Adjust where it reads naturally
Add the topic where it's genuinely missing — usually the H1 or opening — rather than everywhere.
What it checks
- Title
- Whether the keyword is present and its position (the word it starts at) in the title.
- Meta description
- Presence and whether it appears in the first half.
- H1 and subheadings
- Presence in the H1, and how many H2/H3 headings include it.
- Opening text
- Presence in the first paragraph and the first 100 words of visible body text, with the word position of the first match.
- URL slug
- Whether the words of the keyword appear in the page's path (hyphens and underscores treated as spaces).
- Alt text and anchors
- How many image alt attributes and link anchors contain the keyword.
- Body occurrences
- Total exact-phrase occurrences in visible text, for context.
Interpreting the results
Each placement is reported as found or not found, with its position where that's meaningful. “Title: found at word 1” means the title starts with your keyword; “first body occurrence at word 212” means readers get a long way into the page before the topic is named.
Prominence is about signalling the topic clearly and early. It isn't a score to maximise: a keyword in every heading, alt attribute and anchor looks forced to readers and can look manipulative. The summary counts how many of the core placements (title, H1, opening text) include the keyword and treats the rest as optional.
Detected marks facts read directly from what you provided. Guidance marks general recommendations based on those facts — rules of thumb, not guarantees or search engine requirements.
Practical guidance
For most pages, the three placements that matter are the title, the H1 and the opening paragraph — they tell a reader immediately that they're in the right place. Subheadings, alt text and the URL help when the keyword fits naturally, but forcing it into all of them rarely helps and often hurts readability.
A realistic case: a page targeting “shed base” has the phrase in the title and URL, but the H1 says “Getting Started” and the first mention comes 400 words in, after a long company introduction. Rewriting the H1 to “How to Build a Shed Base” and moving the introduction lower makes the topic obvious without adding a single extra keyword.
Links follow the same logic. A link pointing to a page that clearly states its topic is easier for search engines to interpret — which is why we check target pages before placing PBN backlinks or planning a backlink package. Anchor wording matters too; see What is anchor text?. For frequency rather than placement, use the Keyword Density Checker.
Limitations
- Matching is exact-phrase and case-insensitive. It won't recognise synonyms, reordered words or different word forms.
- “Visible text” is approximated by removing scripts, styles and hidden elements from the pasted HTML; navigation and footers are included unless you paste only the main content.
- It checks placement, not relevance. A keyword can be present in every location on a page that still doesn't answer the searcher's question.
Frequently asked questions
Does the keyword need to be the first word of the title?
No. Early is helpful because titles get truncated, but a natural, readable title matters more than exact position.
Should I put the keyword in every heading?
No. Subheadings should describe their sections. Repeating the keyword in all of them reads badly.
Why is my URL shown as not matching?
The checker looks for the keyword's words in the path. If you didn't add the page URL, or the slug uses different words, it won't match.
Is anything uploaded?
No. The HTML is analysed in your browser.
