Enabling Meta Campaign ID in UTM Parameters

To provide accurate and verifiable ad performance insights, Dash.fi matches user events tracked by the Dash.fi Pixel on your site with data from ad platforms (Facebook, Google Ads).  For this matching to work effectively, it's critical that the URLs in your ads contain complete campaign information, especially the campaign_id, along with standard UTM parameters.

What Happens If Parameters Are Missing?

When someone clicks your ad, the Dash.fi Pixel captures their session and activities. We try to match that visit to the exact campaign using data passed in the URL.

If essential information like campaign_id, utm_source, or utm_campaign is missing:

• We can’t identify which exact campaign drove that user.
• Attribution becomes partial or incorrect.
• You lose clarity on what ads are actually working.

What You Should Include in Every Ad URL

Each of these plays a role in our tracking. But without campaign_id, we can’t reliably verify campaign performance from the source platform.

Example of a Well-Tagged Ad URL

https://yourwebsite.com/?utm_source=facebook&utm_medium=cpc&utm_campaign=black_friday_sale&utm_content=carousel_ad1&campaign_id=123456789

Why this works:

• We know the platform (facebook)
• We know it’s a paid ad (cpc)
• We know the campaign context (black_friday_sale)
• We know the creative variant (carousel_ad1)
• We have an exact campaign match via campaign_id

This gives us 100% confidence when linking website events to ad campaigns in your Dash.fi audits.

What a Poorly Tagged URL Looks Like

https://yourwebsite.com/

This gives us:

• No source
• No medium
• No campaign name

• No campaign ID

  ➡️ Result: No reliable attribution

Why campaign_id Deserves Extra Attention

While UTM parameters provide descriptive context, they can sometimes be:

• Misnamed (utm_campaign=spring2025test vs Spring_2025_Final)
• Inconsistent across ads
• Not unique across platforms

But campaign_id is:

• Automatically assigned by platforms like Google and Facebook
• Globally unique
• Traceable directly to your ad dashboard
• Immune to naming inconsistencies

That’s why we recommend treating campaign_id as mandatory, and supporting it with clean UTM parameters.

Platform Examples for Adding campaign_id

Facebook Ads URL template:

?utm_source=facebook&utm_medium=cpc&utm_campaign=summer_launch&campaign_id=

Google Ads Final URL Suffix:

utm_source=google&utm_medium=cpc&utm_campaign=summer_launch&campaign_id={campaignid}

This ensures every ad carries the data Dash.fi needs to give you accurate tracking.
