Maximizing Google Ads Performance with Enhanced Conversions

Monitoring and Optimization

Once you've implemented Enhanced Conversions, it's crucial to monitor its performance and make adjustments as needed.

Performance Review

Regularly assess your conversion data in Google Ads for accuracy and any discrepancies. Compare the data before and after implementing Enhanced Conversions.

Improvement = (Enhanced Conversions - Standard Conversions) / Standard Conversions * 100

For example, if you were tracking 100 conversions per week with standard tracking and now see 120 conversions with Enhanced Conversions, the improvement would be:

(120 - 100) / 100 * 100 = 20%

If you notice any unexpected changes or inconsistencies, review your implementation and adjust your Enhanced Conversion settings accordingly.
