Why don't my Google Ads clicks match my sessions in Google Analytics?

What causes it?

1. Google Ads counts clicks on your ads. Google Analytics counts visits (sessions) and people. They measure different things, so they will never match exactly.

   In the Google Ads help: Google Ads tracks Clicks, while Analytics tracks Sessions and Users. It's important to understand that these are different metrics, and some level of discrepancy is expected.

2. If someone clicks your ad twice within half an hour, Google Ads counts two clicks but Google Analytics may count just one visit.

   In the Google Ads help: If a user clicks your ad twice within 30 minutes without closing their browser, Analytics may register this as one session, even if they left and returned. Google Ads, however, would count two clicks. Clicks and Sessions Discrepancy for Google Ads and Google Analytics: Troubleshoot, read 2026-11-12.

3. Google Ads removes clicks it judges invalid, but Google Analytics still shows the visits those clicks produced, at least at first.

   In the Google Ads help: Google Ads filters out invalid clicks, while Google Analytics initially reports all sessions before potential filtering. Clicks and Sessions Discrepancy for Google Ads and Google Analytics: Troubleshoot, read 2026-11-12.

4. If someone clicks your ad and leaves before your page finishes loading the tracking code, Google Ads records a click but Google Analytics records no visit.

   In the Google Ads help: A user might click an ad but close their browser or navigate away before the Google Analytics tracking code on your landing page fully loads, resulting in a click but no session.

5. People who come back to your site later can still be credited to the ad campaign that first brought them, so you can see more visits than clicks.

   In the Google Ads help: During the lifetime of a given campaign, a returning user to your site is attributed to that one campaign. In such cases, you can expect to see more sessions than clicks. Clicks and Sessions Discrepancy for Google Ads and Google Analytics: Troubleshoot, read 2026-11-12.

How do I check it myself?

1. Check that auto-tagging is turned on in Google Ads. It adds a tag to each ad click that lets Google Analytics recognise the visit as coming from your ads.

   In the Google Ads help: Ensure that your Google Ads account has auto-tagging turned on to allow the GCLID parameter to be automatically appended to your URLs. Clicks and Sessions Discrepancy for Google Ads and Google Analytics: Troubleshoot, read 2026-11-12.

2. Open your ad's landing page with a test tag added to the end of the address and see whether the tag is still there on the page you end up on. If a redirect strips it, the visit can lose its link to the ad.

   In the Google Ads help: Test your landing page URLs directly by appending parameters (for example ?gclid=test or ?utm_source=test) to see if they persist after the redirect and on the final landing page.

3. Make sure every page your ads send people to has your Google Analytics tracking on it.

   In the Google Ads help: Ensure that you're tracking all landing pages for your Google ads. Clicks and Sessions Discrepancy for Google Ads and Google Analytics: Troubleshoot, read 2026-11-12.

4. If you compare dates from before your Google Ads and Google Analytics accounts were linked, the older data will not be filled in after the fact.

   In the Google Ads help: Confirm if the date ranges you’re comparing include periods during which your Google Ads and Google Analytics accounts weren’t linked. Data will not populate retroactively.

How would I know the day it starts?

• Feder reads your ad clicks from Google Ads and your page views and sessions from Google Analytics each day, and compares each with your own history.
• Feder does not expect the two to match. It tells you when either one goes quiet or moves outside its usual range.

Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.

See what Feder reads from Google Ads, which feeds Visits. Feder only reads. It never changes anything in Google Ads.
