Landing page checker: audit your copy in 60 seconds

A checker, not a checklist.

60 seconds, not a 60-minute teardown

Paste a URL, get a scored report. No discovery call, no "book a demo", no PDF that arrives next Tuesday. The checker fetches your live page and runs while you watch.

Median run: ~60s

16 automated checks, free

The free check runs the Clarity and Trust lenses: single dominant H1, jargon in the hero, testimonial quality, proof near claims, and 12 more. The full report runs all 55 checks across 9 lenses.

Every flag cites its source

This isn't a linter of one developer's opinions. Each check traces to Ogilvy, Cialdini, Schwartz, or published CXL Institute research — so you can verify the rule before you rewrite anything.

4 primary sources

What a finding looks like

This one is from our Notion teardown, word for word. Your report lists every failed check in the same format: the check, the quote from your page, and the source.

CL-3mediumNotion · 76/100
Hero 5-second test
Hero H1: 'Where teams and agents Jam together.' Subhead: 'Capture context, find answers, and automate tasks with AI built for your team.' The WHAT is unclear in 5 seconds — 'Jam together' is a vague metaphor that does not communicate whether this is a workspace, a chat tool, a project manager, or an AI assistant. The subhead adds partial clarity but requires reading. WHO ('your team') is broadly stated but not specific enough to be meaningful.
Source: Ogilvy, 'Ogilvy on Advertising' (1983): 'The headline is the most important element in most advertisements. It is the telegram which decides the reader whether to read the copy.' A headline that fails to communicate the product category wastes the primary impression.
