FAQ

Does this keyword checker show search volume or difficulty?

No. It runs fully offline and focuses on list cleanup, basic intent tagging, and optional mention counts in your text.

How are duplicates detected?

By default it trims and collapses spaces, optionally lowercases, then deduplicates on the normalized phrase.

How accurate is the intent classification?

It’s rule-based (e.g., “best”, “pricing”, “how to”, “buy”). Treat it as a quick label, not a final decision.

Can I check if my draft mentions the keywords?

Yes—paste text into the optional box to get mention counts per keyword (whole-phrase match is enabled by default).

What does “slug” mean here?

A slug is a URL-friendly version of a phrase (lowercase, hyphen-separated). It’s helpful for planning URLs or internal anchors.

What’s a good character length for keywords?

There’s no single rule, but very long phrases can be awkward for titles/ads; use the min/max filters to flag outliers.

Is my data sent anywhere?

No. The tool runs in your browser and does not make network requests.
