Why microconversions matter for diagnosis
The macro conversion rate (final signup, purchase, demo booked) is a lagging indicator. By the time it moves, the cause is weeks in the past. Microconversions move first — and let you separate "the page is broken" from "the funnel after the page is broken." If your video plays and scroll-past-75% rates are healthy but signups are down, the page is doing its job and the issue is downstream (broken form, slow checkout, sales-team backlog). If microconversions are also down, the page itself stopped building intent.
What to instrument
Five microconversions cover most landing pages: (1) scroll past 75% of page height, (2) hero video play (if you have one), (3) pricing-page visit, (4) feature-tour or product-tour click, (5) any clicked CTA — even on competing buttons that aren't your primary. Wire these in PostHog, GA4, or your analytics tool of choice. Track week-over-week ratios to your macro conversion to build a baseline conversion model.
The trap: optimizing for the micro
The danger is over-optimizing the leading indicator — making people watch the video without making them sign up. We've seen pages where video plays 3x'd after a redesign but signups stayed flat. That's a sign the video became more entertaining without becoming more persuasive. Microconversions are diagnostic tools, not goals. Keep the macro as the north star and use the micros to find leaks.
