Google Ads Not Converting? Complete Diagnostic Guide

Getting clicks but no conversions is frustrating and expensive. The good news: the problem is diagnosable. The challenge: there are many potential causes.

The Conversion Chain

Every conversion requires:

1. Right audience sees your ad
2. Compelling ad gets the click
3. Relevant landing page keeps them engaged
4. Clear offer motivates action
5. Easy process allows completion
6. Tracking works to record it

A break in any link means no conversion.

Diagnostic Approach

This guide follows a systematic process:

1. Verify tracking is working
2. Check traffic quality
3. Audit the landing page
4. Evaluate the offer
5. Test the conversion process
6. Analyze by segment
