Frequently asked questions
What are typical conversion rates at each funnel stage?
Industry averages: Visitor-to-lead 2–5%, Lead-to-MQL 25–50%, MQL-to-SQL 20–40%, SQL-to-customer 15–30%. Overall visitor-to-customer rates of 0.3–1% are common for B2B SaaS. E-commerce funnels differ — visitor-to-purchase typically runs 1–4%.
What is the difference between MQL and SQL?
A Marketing Qualified Lead (MQL) meets marketing criteria (downloaded content, hit lead score threshold) but is not yet ready for sales outreach. A Sales Qualified Lead (SQL) has been reviewed by sales and confirmed as a genuine opportunity with budget, authority, need, and timeline (BANT).
How do I improve visitor-to-lead conversion?
Improve your lead magnet offer, simplify lead capture forms (fewer fields), add exit-intent popups, and use social proof near opt-in forms. A/B test CTAs on your highest-traffic pages. Even a 1% lift in visitor-to-lead rate compounds significantly across the entire funnel.
Should I optimise the top or bottom of the funnel first?
Optimise the bottom first. Improving SQL-to-customer rate from 20% to 30% requires no additional traffic. Top-of-funnel improvements are only worthwhile after you have maximised the efficiency of what happens after the lead is captured.

How to Use Funnel Data to Find Your Biggest Growth Lever
Most businesses obsess over top-of-funnel traffic while their biggest opportunity lies in converting the leads they already have. A funnel conversion analysis immediately highlights the stage with the biggest drop-off. If 800 leads become only 240 MQLs (30%), but 96 of 240 MQLs become SQLs (40%), the lead-to-MQL stage is the constraint — not SQL-to-customer. Fixing the constraint delivers compounding improvements across every subsequent stage without spending more on acquisition.
B2B vs B2C Funnel Benchmarks
B2B funnels are longer with more decision-makers and lower overall conversion rates — 0.1–0.5% visitor-to-customer is typical. B2C e-commerce funnels are shorter but still multi-stage: visitor → product page → add to cart → checkout → purchase. Cart abandonment alone averages 70%, meaning recovering even 10% of abandoned carts can lift revenue by 7% with zero additional traffic. Use the funnel calculator to model both types of funnels and identify where intervention has the highest leverage.
