Measuring when visitors complete valuable actions so you can tie results back to marketing.

What Conversion tracking means

Without conversion tracking, you cannot tell which ads, pages or campaigns bring in leads and sales. It connects your site to analytics and ad platforms. Accurate tracking is the difference between guessing and managing a marketing budget.

Why it matters for your website

Without tracking, you cannot tell which campaigns bring leads and which just burn budget. Accurate conversion data also feeds ad platforms' bidding systems, helping them find more people likely to buy. Broken or missing tracking is one of the most common reasons ad spend underperforms.

Example

A roofing contractor tracks form submissions and phone clicks as conversions in GA4 and Google Ads. It discovers one campaign drives most of its leads and shifts budget there.

Tips

  • Define which actions count as conversions before setting up tags.
  • Test every conversion by completing it yourself and checking the reports.
  • Track phone calls as well as forms if customers often call.

Common mistakes

  • Counting page views of the contact page as conversions instead of actual submissions.
  • Firing the same conversion twice, which inflates results.

Questions about Conversion tracking

What should I track as a conversion on my website?
Track actions that signal real business value: form submissions, calls, bookings, purchases and sometimes key steps like starting a quote. Avoid counting low-value clicks as conversions.
What is the difference between a conversion and a key event in GA4?
In GA4, Google renamed conversions to key events. Conversions in Google Ads are tracked separately and can be imported from GA4 key events.
