What Is Auto Tagging in Google Ads?
Auto Tagging is a Google Ads feature that automatically adds a unique tracking parameter (gclid) to your destination URLs. This allows Google Analytics to collect detailed campaign, keyword, ad group, and conversion data without manually adding UTM parameters.
Auto tagging significantly reduces the risk of tracking errors and ensures reliable reporting.
Manual Tagging vs Auto Tagging: Key Differences
There are two ways to track Google Ads traffic using URLs:
1. Manual Tagging
Manual tagging requires adding UTM parameters manually to your URLs. This method sends data only to the following Google Analytics dimensions:
- Campaign
- Source
- Medium
- Content
- Keyword (Term)
Common UTM Parameters Used
- utm_source
- utm_medium
- utm_campaign
- utm_content
- utm_term
Example of a Manually Tagged URL
https://www.example.com/?utm_source=google&utm_medium=cpc&utm_campaign=camp1&utm_term=keyword&utm_content=creative
Limitations of Manual Tagging
- Higher chance of human error
- Limited data compared to auto tagging
- Requires manual updates for every campaign
2. Auto Tagging
Auto tagging automatically creates custom URLs that include a Google Click Identifier (gclid). This allows Analytics to show advanced Google Ads metrics, such as:
- Campaign performance
- Ad group data
- Keyword-level tracking
- Conversion attribution
- Offline conversion tracking
⚠️ Important:
Do not use manual tagging and auto tagging together, as this can cause data conflicts and inaccurate reporting.
