By following these steps, you ensure click IDs are correctly captured in your form submissions for accurate ad attribution.

​
1. Add Hidden Fields in Feathery

  1. Open your form and go to Settings > Data Tracking > Edit Hidden Fields.
  2. Add hidden fields with the exact IDs for the platforms you are using:
    • gclid
    • fbclid
  3. Save and Publish your form.
See Feathery’s docs on setting field values from URL params.

​
2. Google Ads: Appending gclid

​
Option A: Auto-Tagging

  1. In Google Ads, go to Settings > Account Settings > Auto-tagging.
  2. Check “Tag the URL that people click through from my ad”.
Google Ads will automatically append ?gclid=XYZ to your final URLs. When users land on your Feathery form, Feathery will detect and populate the gclid hidden field from the query parameter. Learn more about auto-tagging.

​
Option B: Final URL Suffix or Tracking Template

  1. Sign in to Google Ads and open your campaign.
  2. Go to Settings > Advanced settings > Campaign URL options.
  3. In Final URL suffix, enter:
Google will append ?gclid=CLICK_ID (or &gclid=CLICK_ID) to your ad URLs. Optionally, use a Tracking Template instead:
{lpurl} expands to your ad’s Final URL; other placeholders fill at click time.
Use Auto-Tagging (Option A) when:
  • You primarily rely on Google Analytics or Google Ads reports for attribution.
  • You don’t need to control or combine the click ID with other URL parameters.
  • You want a zero-maintenance setup.
Use Final URL Suffix / Tracking Template (Option B) when:
  • You need multiple parameters (e.g. utm_source, campaign, gclid) in a specific order.
  • You’re using a non-Google analytics platform or a mix of tools with custom UTM naming.
  • You want different URL-parameter strategies across ad groups or individual ads.

​
3. Facebook Ads: Appending fbclid

Facebook automatically appends ?fbclid=… to destination URLs on ad clicks. Ensure your Feathery form URL accepts unknown query parameters so it arrives as:
If your form host strips unknown params, explicitly set URL parameters in Ads Manager under Tracking > URL Parameters:
Learn more about Facebook URL parameters.

​
4. Combined URL Setup

Example URL where both fbclid and gclid are collected:
  • Google Ads → Final URL suffix: gclid={gclid}
  • Facebook Ads → URL parameters: fbclid={fbclid}

​
5. Verification

  1. In Google Ads, go to your campaign’s Ads & extensions and create a draft ad pointing at your Feathery form URL. Leave it as a draft or pause the ad group.
  2. Click the Ad Preview & Diagnosis icon (🔍) in the top-right corner.
  3. Enter a keyword from your draft ad and click the ad headline in the preview pane.
  4. You’ll land on your Feathery form URL with ?gclid=… appended.
  5. Submit the form, then check Feathery’s Results tab to verify the gclid field captured the previewed click ID.

​
Facebook Ads

  1. In Ads Manager, create a draft ad. Set the Website URL to your Feathery form and add fbclid={fbclid} under Tracking > URL Parameters. Do not activate or publish.
  2. In the Ads table, check the box next to your draft ad and click Preview > Facebook Feed.
  3. In the preview pane, click the Share icon and copy the link. Paste it into a new browser tab.
  4. Your form URL will include ?fbclid=IwAR… in the address bar.
  5. Submit the form, then check Feathery’s Results tab to confirm the fbclid field captured the click ID.
