What is the AltF Signals opportunity score?

An AltFTool editorial judgement on a 0-100 scale, not a measured metric. It is not sourced from an SEO platform, it is not audited, and it is not a prediction of commercial success. Competition and momentum labels are editorial in the same way.

Which numbers on AltF Signals are actually live?

One: the relative search-interest chart on each signal page, which is fetched from Google Trends when the page loads and is a 0-100 relative index rather than absolute volume. Everything else comes from a hand-reviewed snapshot last checked 2026-07-22.

Does AltFTool have a tool for every category it researches?

No. Of the 12 tracked categories, 7 have a working AltFTool tool and 2 are only partly covered. 3 have nothing behind them - AI content detector, Plagiarism checker, AI writing humanizer - and those pages say so and are excluded from search indexing rather than competing for a query they cannot answer.

Can I get the AltF Signals data as JSON?

Yes. GET /api/signals returns the catalogue with a dataAsOf date, a count and a results array, and accepts q, category, momentum and sort parameters. It needs no API key and is rate limited to 60 requests per minute.
