What Does CRO Mean? Conversion Rate Optimization Explained (Process, Examples, Tools and Quick Wins)
What CRO stands for in marketing
In this article
In digital marketing, CRO stands for conversion rate optimization: the practice of increasing the percentage of website or app visitors who take a desired action, such as buying, booking, signing up or requesting a quote. Instead of buying more traffic, CRO gets more results from the traffic you already have by understanding visitors and improving pages, offers and user experience. (In other fields, CRO can also mean Chief Revenue Officer or Contract Research Organisation.)
Conversion rate basics
Conversion rate = conversions ÷ visitors × 100
If 2,000 visitors produce 60 leads, the conversion rate is 3%. Raise it to 4.5% and you get 90 leads from the same traffic and ad spend. (More: What is a landing page conversion?)
Why CRO matters
- Lower acquisition costs: more customers for the same budget
- Higher ROI from ads, SEO and content
- Better user experience
- Customer insight: you learn what persuades your audience
- Compounding gains: small improvements across the funnel multiply
The CRO process
- Define goals and metrics: primary conversion, micro conversions, revenue per visitor
- Analyse data: analytics funnels, drop-off points, device and source differences
- Qualitative research: heatmaps, session recordings, surveys, user tests, sales and support feedback
- Form hypotheses: "Because users can't find pricing, adding a pricing section will increase demo requests"
- Prioritise: frameworks like PIE or ICE (impact, confidence, ease)
- Test: A/B or multivariate tests with enough traffic
- Analyse and implement winners
- Document learnings and repeat
