Landing Page Checklist Grader

How this tool computes its result

A fixed list of 11 weighted checklist items (weights 8–10, e.g. value proposition headline, message match, CTA above the fold, form friction, social proof, trust cues, mobile speed, confirmation step) sums to a `totalWeight` via reduce. Checking a box adds its weight to `completedWeight`. Score = `round(completedWeight / totalWeight * 100)`, mapped to a letter grade (≥85 A, ≥70 B, ≥55 C, else D). "Top improvements" lists unchecked items sorted by weight descending, showing the top 3.

Worked example

Total weight across all 11 items = 100. Checking the seven highest-weight items (value prop 10, message match 10, CTA above fold 10, form friction 10, social proof 10, next step 10, benefits 8 = 68 points) leaves subheadline, visual, trust elements, and mobile-fast unchecked (each worth 8) → score = round(68/100*100) = 68 → Grade C, with the three unchecked 8-point items surfaced as top improvements (tie broken by array order since sort is stable on equal weight).

When not to use this tool

This is a self-reported checklist, not an automated page scan — checking a box records that the user believes the criterion is met, it never inspects a live URL or DOM, so an inaccurate self-assessment produces a misleading grade with no way for the tool to catch it.

Common mistakes

• - Treating the numeric score as an automated audit result rather than a reflection of manually checked boxes — nothing about the page itself is verified.
• - Assuming all 11 items carry equal weight; the 10-point items (headline, message match, CTA placement, form friction, social proof, next step) count noticeably more toward the grade than the 8-point items.
• - Using the notes field to track item-specific follow-ups — notes are freeform and only appended at the end of the downloaded report, not linked to individual checklist rows.
