Conversions & goals explained
A plain-English guide to conversions and goals in Google Analytics 4 — what counts as a conversion, how they are tracked, and why they are the most important metric on your site.
Traffic numbers are interesting. Conversion numbers are vital. A conversion is when a visitor takes the specific action you actually want them to take on your website. This guide explains what conversions are and why they matter far more than raw visitor counts.
Quick summary
A conversion is any action that matters to your business — a form submission, a phone call click, a purchase, a file download. GA4 tracks these as "key events" (formerly called goals). A high conversion rate means your website is working. A low one means something needs attention.
What is a conversion?
A conversion is a valuable action taken by a website visitor. What counts as a conversion depends entirely on your business goals.
Common conversions include:
- Submitting a contact form
- Clicking your phone number
- Completing a purchase (for online stores)
- Downloading a brochure or guide
- Signing up for an email newsletter
- Booking a call or appointment
- Watching a key video
You decide what matters. GA4 tracks it.
Why conversions matter more than traffic
It is tempting to celebrate when your visitor numbers go up. But traffic without conversions is just noise.
Consider this scenario:
- Website A: 5,000 visitors per month, 10 enquiries
- Website B: 1,000 visitors per month, 40 enquiries
Website B is performing far better for business — even though it has one-fifth the traffic.
The metric that captures this difference is conversion rate: the percentage of sessions that result in a conversion.
Website A: 0.2% conversion rate Website B: 4% conversion rate
How GA4 tracks conversions
In GA4, conversions are tracked as key events (this is the newer GA4 terminology — you may also hear them called "conversion events").
Chykalophia sets up key events for you when we install GA4. Common ones we configure include:
form_submit— when your contact form is submittedphone_call— when someone clicks your phone numberpurchase— for e-commerce stores- Custom events for specific actions on your site
Once these are set up, GA4 automatically counts them and shows you conversion totals in your reports.
Where to find conversions in GA4
In GA4, go to Reports > Engagement > Conversions. You will see a list of all your key events with:
- The number of times each event was triggered
- The number of users who triggered it
- The conversion rate
You can also see conversions broken down by traffic source — so you can see which channels (Google search, social media, email) are driving the most valuable actions.
Check conversions by traffic source
Go to Reports > Acquisition > Traffic acquisition, then change the metric to "Key events" or "Conversions." This shows you which channels drive not just visits, but actual business outcomes.
Conversion rate: what is good?
Average conversion rates vary enormously by industry and by what the conversion is. Some rough benchmarks:
| Conversion type | Typical range |
|---|---|
| Contact form submission | 1–5% of sessions |
| E-commerce purchase | 1–3% of sessions |
| Newsletter signup | 1–4% of sessions |
| Lead magnet download | 3–10% of sessions |
If your rate is significantly below these ranges, there may be friction in the user journey — unclear calls to action, too many form fields, or a slow-loading page.
Micro vs macro conversions
A macro conversion is your primary goal — a purchase, an enquiry, a booking.
A micro conversion is a smaller step that suggests interest — watching a video, clicking to your pricing page, spending more than two minutes reading.
Tracking both gives you a more nuanced picture. High micro conversions with low macro conversions means people are interested but something is stopping them from taking the final step.
