Frequently asked questions

Why are some of my keywords disappearing before generation?

Every keyword must have a numeric search volume. CSV rows where the volume cell is empty or non numeric are skipped silently, and in manual entry any line that is not a keyword,volume pair is ignored. Compare the "Prepared N keywords" count against your file before generating.

Is every keyword guaranteed to appear in the sitemap?

No. Inclusion is requested in the prompt, then after generation the app compares output against input case insensitively and shows a warning listing missing keywords, plus an info notice for extra category names the model invented. There is no automatic retry, so regenerate if the missing list matters.

Is there a practical size limit on the keyword list?

The model response is capped at 4,000 tokens, and the entire hierarchy including every keyword has to fit in that JSON response. Very large lists can be truncated mid JSON and fail to parse, so split big keyword sets into batches if generation errors.

What does it cost to run?

One OpenAI chat completion per generation on your own API key. Input tokens scale with the keyword list, which is sent as JSON with volumes, and output tokens with the hierarchy size. gpt-4o-mini is the default and cheapest of the three model options, and temperature is fixed at 0.
