How to track ROI from your website
Last updated 3 July 2026 | Websites for Trades editorial team
1 min read"How's your website performing?" If you can't answer with numbers, you can't improve it. Here's the minimum stack you need.
1. Google Analytics 4 (free)
Replaced Universal Analytics in 2023. Set up event tracking for form submissions, phone clicks, scroll depth, and outbound clicks.
2. Form tracking
Every form on the site fires a GA4 event with the form ID. Lets you see which forms convert best, which fields people abandon.
3. Call tracking
Use a service like CallRail, Mediahawk or Phonewagon. They give you dynamic numbers that swap based on traffic source, so you can see "Google Ads sent us 12 calls last month, organic SEO sent 18". Critical for trades.
4. Google Search Console (free)
Shows what keywords you actually rank for, click-through rates, technical issues. Most businesses leave it disconnected.
5. Conversion goals tied to revenue
Tag every conversion with an estimated value. Even if it's rough ("each enquiry = average £200 of revenue x 30% close = £60"), it lets you compare channel ROI properly.
What not to use
- Bounce rate (deprecated in GA4, was a misleading metric anyway).
- Average session duration (heavily skewed by single-page visits).
- "Total page views" with no conversion context.

Frequently asked questions
What is the minimum website ROI tracking setup?
At minimum, track form submissions, phone clicks, key button clicks, traffic source, landing page and an estimated value for each qualified lead.
Do small businesses need call tracking?
Call tracking is very useful for service businesses because many high-value leads happen by phone rather than through forms.
Is bounce rate a good ROI metric?
No. Bounce rate does not show revenue or lead quality. Conversions, qualified enquiries and booked jobs are more useful website ROI metrics.
