## Markdown access

Every public HTML page has an explicit Markdown alternate. Use the exact URLs below instead of guessing routes. The homepage Markdown URL is `/index.md`; every other public page appends `.md` to its canonical HTML path. A client may also request the canonical HTML URL with `Accept: text/markdown`. Negotiated responses include `Content-Type: text/markdown`, `Content-Location`, and `Vary: Accept` headers.

## Core benchmark facts

- Each run freezes 25 questions: 20 neutral discovery questions and 5 target-named diagnostic questions.
- The same 25 questions are sent to four providers, creating 100 planned answers.
- Shared web-search grounding is required. Failed, unsupported, or unsourced results are excluded from eligible-score denominators and remain visible in coverage.
- Headline measures include discovery visibility, prominence, share of voice, claimed-domain citation rate, sentiment, and coverage.
- Metrics are marked provisional below 90% coverage.
- Completed reports include up to five evidence-linked actions plus owner-only PDF and CSV exports.
- Reruns reuse the same questions and compare visibility, citations, competitor mentions, and coverage against the baseline.
- Results are time-stamped, directional API-grounded snapshots and do not claim parity with consumer chat products.
- Runs are private to the authenticated owner. The default answer-retention window is 30 days.
- Billing uses prepaid benchmark credits, not a subscription: $9 for a first benchmark, then $15 for one, $39 for three, or $99 for ten. Credits are valid for 12 months.
- Best fit: consultants, agencies, and in-house teams that need a bounded baseline, evidence-linked deliverable, or comparable post-implementation rerun.
- Not a fit for: teams that require daily alerts, continuous prompt monitoring, Perplexity coverage, or consumer-chat-interface replication.

## Important limitation

The generated question set is not claimed to be a random or statistically representative sample. With 25 questions, a simple worst-case interval is roughly plus or minus 20 percentage points; this is a scale cue, not a precision claim.
