Frequently asked questions
- How much of my content is actually analysed?
- Only the first 8,000 characters are sent to the model, whether pasted or from a file. Keywords that appear only later in a long article will not be extracted, so put key sections first or split long content into chunks.
- How does the verbatim validation work?
- After the model responds, every keyword is checked as a case-insensitive substring of your full content and anything not found is silently dropped. This stops the model inventing phrases, but it also means paraphrases the model returns disappear without warning, which is one reason you may get fewer keywords than the per-category limit.
- Why did the anchor exclusion remove so many keywords?
- The filter is substring-based in both directions: a keyword is removed if it contains an existing anchor or an existing anchor contains it. A short anchor like 'welding' will eliminate every extracted phrase containing that word, so keep the exclusion list to specific multi-word anchors.
- Can it fetch content from URLs?
- No. There is no scraping in this tool; the URL and H1 fields are passed to the model as context only. You must paste content or upload a CSV/Excel file with a content column (plus optional URL, H1 and existing-anchors columns for bulk runs).
- Are results reproducible?
- With Claude, yes in principle: calls use temperature 0 and a 2,000 output token cap. With OpenAI, the response is forced into a strict JSON schema but the temperature is not pinned, so runs can differ slightly. Bulk mode adds a 1 second pause per row.
