Ranked by what each change is worth on the composite — the gap to the next rung of the ladder times the dimension’s weight. Computed from the scores, not written by the model; the model’s sentence under each is the action.
Replace abstract terms like 'Designed For Long Running Agents' and 'MCP' with explicit features such as CLI control (--json), static IPs, and per-minute pricing.
Pair the primary CTA with pricing or a trial cue, such as 'Start with pay-as-you-go pricing' or 'Try a VM today'.
Include an additional quantified stat (e.g., uptime or provisioning speed) beyond the current 99.99% uptime to diversify proof.
All three together: 82 → 90. Every dimension one rung up: 90 (grade A). Ceiling is 95.
Built only from facts already on the page — not the company’s words. Shown so the gap between what was written and what could have been written is concrete rather than a number.
Five alternative headlines in five angles, a subhead, a call-to-action line, and a line-by-line edit for each of the five dimensions — written only from facts already on machine0.io, gated like a rating (anything with a struck word is dropped, not sold). Delivered on a private page in about a minute.
Five dimensions on one ladder — 5 · 20 · 35 · 50 · 65 · 80 · 95 — weighted clarity 30%, specificity 20%, jargon 20%, proof 15%, call to action 15%. For each: the rung the page matched, the words that drove it, and what would reach the next rung. Full rubric →
The headline explicitly states the product category (virtual machines) in plain terms.

Strongest: Clarity 95. Weakest: Jargon-free 65. The 3 passes agreed within 6 points.
No word in the headline itself was judged empty, yet jargon-free scores 65: the scorer found generic phrasing further down the page. Several phrases use abstractions and domain-specific terms (e.g., MCP, profiles, Claude Code, Codex).
