What is Page Keyword Checker?
Keyword Density Checker counts terms in the text you paste and shows frequency so you can balance emphasis without stuffing. Paste a draft, review the top terms, adjust wording, then re-check the same sample. Agents can fold keyword checks into SEO playbooks on MCP and verify after edits — see <a href="/developers/seo-agent">SEO agent</a>. Browser use is free; API-backed calls share REST/MCP credits.
What are common questions about Page Keyword Checker?
What does Keyword Density Checker measure?
Word and phrase frequency in pasted text so you can see which terms dominate a draft.
Does it have REST and MCP access?
Yes when the tool is API-backed in the catalog. Use the same API key for REST and MCP with one monthly quota.
Is the browser tool free?
Yes for typical browser use. API/MCP quota applies when you call the API-backed surface with a key.
Should you paste confidential copy?
Prefer non-sensitive drafts. Remove secrets before pasting; clear the field when you finish.
Is it only for single keywords?
No. Use it to review repeated words and phrases together, then revise for readability.
How do you avoid keyword stuffing?
Trim terms that repeat far above nearby phrases, then re-check the same draft until the list looks balanced.
What are the key features of Page Keyword Checker?
Count term frequency
Measure how often words and phrases appear in the text you paste so emphasis is visible at a glance.
Spot repetition
Identify terms that dominate the draft so you can trim stuffing and keep wording natural.
Refine then re-check
Edit the draft and paste the same sample again to compare counts before you publish.
Stay on-page
Review results in the browser panel without exporting private drafts unless you choose to copy them.
How do you use Page Keyword Checker?
Paste your draft
Place the text sample into the input area on this page.
Edit and verify
Adjust repeated terms, paste the revised draft, and confirm counts look balanced.
Run the density check
Start the analysis and review the frequency list in the results panel.
How does Keyword Density Checker handle privacy?
Text is processed for the browser session so you can read counts on the page. Do not paste passwords, customer PII, or confidential contracts. For API or MCP, keep keys private and rotate exposed keys.
How do you troubleshoot odd counts?
Paste plain text without heavy HTML, remove boilerplate nav blocks, and re-run. If counts look skewed, shorten the sample to the main body only and compare against a clean control paragraph.
What are 3 use cases for Keyword Density Checker?
Balance a blog draft before publishing. Compare two product-page variants on the same topic terms. Spot overused phrases in FAQ copy after a rewrite pass.
