How to Measure the ROI of Your B2B Website | Tolosa Designs

Many Swiss executives invest in a new website without ever knowing how much it returns. While defining the ROI of an e-commerce is simple, it's much more complex for a B2B service business where the final sale happens offline.

1. Define Measurable Goals (Macro and Micro Conversions)

On a B2B site, your MACRO-conversions are contact form submissions, quote requests, or phone calls triggered from mobile. Your MICRO-conversions are whitepaper downloads, newsletter sign-ups, or reading a concrete business case.

2. Assign Financial Value to Leads

Here's the calculation:

- What is your "Qualified Prospect to Client" conversion rate? (e.g.: 25%)
- What is the average value of a new contract (LTV)? (e.g.: CHF 10,000)
- Prospect value = 10,000 × 25% = CHF 2,500.

If your site generates 4 qualified leads per month, it generates CHF 10,000 in monthly pipeline value.

3. Configure Google Analytics 4 (GA4)

It's essential to configure custom event tracking in GA4. Stop looking at "page views". Look at engagement rate, traffic origin (SEO vs Social), and conversion paths that lead to contact email clicks.
