GRADE B
BAND 65–75

What their homepage claims

“Powering the best of the internet | Fastly Take control of all AI and agent traffic with Fastly AI Runtime Control Learn more”

What that means

Fastly operates a global content delivery and edge compute service with AI tools to manage traffic, protect content from bots, and run code at the edge with real-time visibility.

Verdict

The copy signals a broad, platform-oriented offering with strong proof of performance, but it does not present a single concrete product noun in the opening, limiting immediate clarity about what a buyer should buy.

What to fix first

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.

  1. 1Clarity quick win 50 → 65+4.5

    Replace the opening line with a concrete product noun: 'Fastly CDN and edge compute for global delivery'.

  2. 2Jargon-free quick win 50 → 65+3

    Use buyer-focused wording that describes capabilities without abstractions, e.g., 'protect apps from bots while delivering real-time content at global scale'.

  3. 3Call to action quick win 80 → 95+2.3

    Place a single, unambiguous CTA directly under the main product statement, such as 'Learn more'.

All three together: 70 → 80. Every dimension one rung up: 80 (grade A). Ceiling is 95.

“Fastly provides a global CDN with edge compute and security.”

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.

How this compares

48%of the index scores lower
+1vs index mean (69)
-1vs infrastructure mean (71)
0vs median (70)
100%of headline words survive
3×independently scored

Strongest: Specificity 95. Weakest: Clarity 50. The 3 passes agreed within 6 points. The band 65–75 is where a re-score of this unchanged page would most likely land: on 42 dry re-scores (12 Oct 2026) the median move was 6 points and one in four moved more than 10. A grade only changes when a new score clears the boundary by 5.

Nothing struck

No word in the headline itself was judged empty, yet jargon-free scores 50: the scorer found generic phrasing further down the page. Headlines rely on abstractions like platform and programmable platform.
