What is Keyword Density 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. Use 1 draft revision cycle before publishing so counts stay easy to compare. The workflow stays linear: enter input, run, read findings, fix one item, then verify on the identical sample so comparisons stay honest across two passes.

What are common questions about Keyword Density Checker?

What does Keyword Density Checker measure?

Word and phrase frequency in pasted text so you can see which terms dominate a draft.

Is it only for single keywords?

No. Use it to review repeated words and phrases together, then revise for readability.

Is the browser tool free?

Yes for typical browser use. API/MCP quota applies when you call the API-backed surface with a key.

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.

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.

Should you paste confidential copy?

Prefer non-sensitive drafts. Remove secrets before pasting; clear the field when you finish.

What are the key features of Keyword Density 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.

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.

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.
