A conversion is often treated as a single event - the purchase, the form submission, the sign-up. In reality, every conversion is the end of a chain of smaller decisions. Understanding that chain is what separates a CRO programme that improves checkout rates from one that improves checkout rates, session depth, add-to-cart rates, and video completion rates simultaneously.
Macro conversions: the primary goal
A macro conversion is the primary goal of the page or campaign - the action that directly drives business value. Examples:
- Completing a purchase (e-commerce)
- Submitting a lead enquiry form (B2B, property, financial services)
- Booking an appointment (healthcare, real estate, hospitality)
- Signing up for a paid subscription (SaaS)
- Calling a phone number (service businesses)
Micro conversions: the signals
Micro conversions are the smaller, intermediate steps that signal intent and precede the macro conversion. They matter for two reasons: they reveal where friction exists in your funnel, and they give you a measurable conversion event on low-traffic pages where macro conversions are too rare to test against.
- Adding a product to cart
- Watching more than 50% of an explainer video
- Downloading a brochure or pricing guide
- Scrolling past a key information section
- Using an interactive tool (mortgage calculator, size guide, configurator)
- Clicking a phone number on mobile
- Spending more than 3 minutes on a pricing page
Why micro conversions change your testing strategy
A page that gets 500 macro conversions per month can support an A/B test. A page that gets 50 cannot - at least not on the macro metric. But if that page gets 2,000 video plays or 1,800 pricing-guide downloads, you have a test-ready conversion event. Micro conversions unlock testing for low-traffic pages.
Industry breakdown
| Industry | Macro Conversion | Key Micro Conversions to Track |
|---|---|---|
| E-commerce | Purchase | Add to cart, checkout initiation, coupon code applied |
| Property / Real Estate | Enquiry form submitted | Floor plan download, virtual tour views, price guide request |
| B2B SaaS | Free trial sign-up | Pricing page visit, feature video play, demo request |
| Lead generation | Form submission | Phone number click, live chat opened, return visit |
| Media / Publisher | Newsletter sign-up | Article scroll depth, second article viewed, time on site |
When to focus on micro conversions
There are three specific situations where prioritising micro conversions is the correct strategy:
- Low-traffic pages: insufficient macro conversion volume for statistically valid A/B tests. Use micro conversions as the primary test metric instead.
- Long sales cycles: B2B deals that take weeks or months to close. Track engagement depth and intent signals, not just form submissions.
- Complex funnels: multi-step checkout or onboarding flows where micro conversions at each step reveal exactly where you're losing people.
Setting up micro conversion tracking
In Google Analytics 4, micro conversions are created as custom events. The most valuable ones to instrument first:
Primary documentation: Google Analytics: recommended events
- Scroll depth (25%, 50%, 75%, 90% of page height)
- Video play and percentage watched (25%, 50%, 75%, 100%)
- File downloads (PDFs, pricing guides, brochures)
- Outbound link clicks
- Add to cart (if not tracked as standard e-commerce)
- CTA button clicks (track as events even if the destination is another page)
