Marc's analytics tool, graded against the rules Marc wrote — and it's a clinic on most of them. A free trial, not a free plan (#1); numbers everywhere — “18,512 users,” “142 visitors found, 9 became customers” (#3); six testimonials (#29); his own face on a “Hey, Explorer from Earth 🌍 I'm Marc” note (#15); a live demo dashboard (#10, #25). The slips are small and honest: “Revenue-first analytics” is a clean category label where #18 wants a feeling, the trial is “no card required” where #8 wants payment before data, and the pricing shows two tiers where #12 wants three.

Category scores
Fix these first.
Ordered by how much each one is costing you. Start at the top.
- 1
A category label where the rule wants a feeling
rule 18Found: Rule #18: a headline should “make people laugh, say wow, or think what the fuck is this.” “Revenue-first analytics” is an accurate, clear category descriptor — and emotionally flat. The author's own strictest rule is the one his headline grades softest on.
Fix: Lead with the feeling the product delivers — knowing exactly which tweet paid the rent — then let “revenue-first analytics” be the subline.
- 2
“No card required” isn't a hard paywall
rule 8Found: Rule #8: “Ask for payment before asking for data.” The hero promises “14-day free trial. No card required” — signup before payment, the inverse of the hard paywall #8 describes.
Fix: This is a deliberate funnel choice for a validated SaaS, so it's a knowing trade, not a mistake — but by the letter of his own rule, it's a miss worth owning.
- 3
Two tiers, not three
rule 12Found: Rule #12: “Keep it to three choices: Good. Better. Best.” The page shows Starter ($9/mo) and Growth ($19/mo) — two options.
Fix: Add a third tier (a team/scale plan) so the pricing reads as a Good/Better/Best decision instead of a binary.
The rest of the rubric
Needs work
- Footer isn't built to be sharedlow confidencerule 4
Rule #4: “Finish strong.” An analytics tool sits on shareable numbers — engineer the last screen to push a card people post.
- OG image not verifiedlow confidencerule 5
Rule #5: the share card is the most-seen asset. We can't confirm it from the live render — flagged low-confidence.
- Customer-voice copy unverifiedlow confidencerule 14
Rule #14: “Write like your customers talk.” The testimonials are there; we can't confirm the headline copy is lifted from them.
