Conversion funnel

Represents the succession of specific steps that a user goes through on a website or app between their first visit and a final conversion action, such as a purchase, a sign-up, or a contact request. It formalizes the process of turning visitors into customers, by modeling the behavioral and decision-making journey in a digital environment.

Typical funnel steps:

1. Arrival on the site: via SEO, advertising campaigns, social media, or direct traffic.
2. Discovery of offers: exploration of product pages, services, informational content.
3. Selection: adding to cart, clicking to a form, making contact...
4. Transactional engagement: start of the purchase process or form completion (checkout, sign-up, booking...).
5. Final conversion: actual completion of the expected action.

CRO challenges:

Optimizing the conversion funnel is a major performance lever. It aims to:

• identify friction points (e.g.: cart abandonment, steps that are too long, usability issues),
• formulate improvement hypotheses based on behavioral analysis and user feedback,
• test concrete solutions through A/B tests, user tests, or interactive prototypes,
• measure and iterate to build a smoother, more reassuring funnel that is better aligned with expectations.

Analysis tools and methods:

• Quantitative: GA4 (custom funnels, drop-off rate by step), Mixpanel, BigQuery, scroll/click heatmaps, form completion rate.
• Qualitative: user testing, session replays (Hotjar, Clarity), verbatims, VoC, post-conversion NPS.
• Segmentation: funnel analysis by user profile (new vs returning, mobile vs desktop, acquisition channels...).

Benefits of an optimized funnel:

• Improved overall conversion rates,
• Reduced customer acquisition cost (CAC),
• Increased user satisfaction and trust,
• Better profitability of marketing actions,
• Smoother, more consistent customer experience at every step.
