What screenshots catch that Lighthouse misses
A cookie banner covering the CTA, a font that failed open, a hero that cropped on mobile, a pricing table that wrapped into nonsense — none of that is “INP,” and all of it loses money.
Diffs are not about pixel perfection. They are about noticing that last night’s deploy changed the story visitors see.
Keep noise down
Watch money pages first: home, pricing, signup. Ignore pages that intentionally rotate ads every hour.
Compare against the previous good run, not against an ancient baseline from a redesign you already shipped.
Schedule it
AuditHQ stores screenshots with audits so visual history sits next to scores and competitor deltas — one timeline instead of three Slack threads.
