The Analytics Google Ads reports import data directly from the Google Ads system. The data in Google Ads and Analytics is usually consistent, however, there are circumstances in which the data can differ:
- Comparing long date ranges may include periods during which your accounts were not linked.
- Linking multiple Google Ads accounts to the same Analytics view complicates the information in your reports.
- Filters may remove some of the data from your Analytics reports. Check that there are no filters editing your campaign final URLs.
- Google Ads data is imported into Analytics at the time you view your report, so data is current as of the most recent hour.
Use the check list provided here to verify your configuration. See the rest of the article for further discussion of why data differences can occur.In this article:

Discrepancies between clicks and sessions
If you're experiencing any of the following discrepancies between clicks and sessions, you can use the clicks vs. sessions troubleshooter to identify and resolve problems.
If your're seeing (not set) as the value for your Google Ads data (e.g., as the value for the Account or Campaign dimension), use the (not set) troubleshooter to identify and resolve the cause.
There are a number of reasons why Google Ads and Analytics may report different numbers of clicks and sessions:
- Clicks and Sessions are different metrics.
Google Ads tracks Clicks, while Analytics tracks Sessions. If a user clicks on your ad twice within thirty minutes without closing his or her browser, this is registered by Analytics as one session, even if the user left your site and then returned shortly after. For example, if a user clicks on your ad once, clicks the back button, and then clicks your ad again, Google Ads registers two clicks while Analytics registers one session.
- Google Ads filters invalid clicks from your report, while Analytics shows all data.
Google Ads automatically filters certain clicks from your reports, while Analytics reports on all the resulting sessions. The clicks we filter from your Google Ads reports are the occasional instances of someone clicking repeatedly on your ad in order to increase your costs or to increase your clickthrough rate. Google Ads considers these clicks to be invalid and automatically filters them from your Google Ads reports. You are not charged for these potentially invalid clicks.
- You turned off auto-tagging for your URLs in your Google Ads account.
If auto-tagging is turned off, and you did not manually tag the final URLs with campaign tracking variables, the traffic is not marked as Google CPC (clicks that came through from Google Ads ads), but instead may be attributed to Google Organic (clicks from organic search results on Google.com). Ensure that your Google Ads account either has auto-tagging turned on or has campaign tracking variables appended to the end of every final URL.

- Make sure your Google Ads Import & Export Settings are correct.
If you are sure the accounts are linked and you still do not see click or cost data, check to make sure that you have selected the option to import the data from the linked account to the view in question.

- Your site has a server side URL rewrite
Adding additional parameters to your URL may cause your rewrite rule to break. A small percentage of websites do not allow arbitrary parameters in the URL and consequently serve error pages when you include those parameters. We suggest that you lobby your webmaster to allow arbitrary URL parameters.
- Your landing page might redirect to a different page.
Redirects in landing pages can often keep the Analytics code from launching and properly identifying the traffic as having come from a paid search campaign. For example, if your ad leads to
http://www.mydomain.com/page2.html, the campaign information that was originally appended to the landing page is lost upon redirection.
Learn how to track redirecting pages.
- Make sure the landing page for your ads is being tracked.
If the landing page for your ads is not being tracked, your campaign information is not passed to Analytics. Ensure that you are tracking all landing pages for your Google ads.
- Users might have set their browser preferences in ways that prevent Analytics used on websites from collecting data.
- Make sure your landing page is able to load the code properly.
Clicks reported on Google Ads but not on Analytics may be the result of an obstruction between the Google Ads click event and the ability to load the tracking code on the landing page. If this is the case, ensure that your web hosting servers are functioning properly, the page is loading for all possible users and IPs, and the tracking code is installed correctly on your web pages.
Learn how to check that you've installed the Analytics code properly.
- Users return during the lifetime of a campaign.
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. To see the number sessions from returning users, cross-segment the campaign by User Type.
- Users return to your site via bookmarks.
Analytics uses the gclid parameter in your final URLs to identify traffic from Google Ads ads. The gclid parameter shows up in your landing page URL when a user arrives at your site from your ad. For example, if your site is
www.example.com, when a user clicks on your ad, it appears in the address bar as:
If users bookmark your website along with the gclid parameter, Analytics records traffic from these bookmarks arriving from your Google Ads ads. However, Google Ads doesn't record the clicks (and advertisers are not charged for these sessions since they're not actual clicks on the ads).
- Server latency
If a user comes to your site from an ad, and then leaves the landing page before the tracking code executes, then the gclid parameter is never passed to the Google servers, and that click is not associated with the session. The result is a clicks vs. sessions discrepancy.
Discrepancies in the Conversion Rate
In Analytics, Conversion Rate is the percentage of users that convert on at least one of the Goals you have defined for that view. This is different than the Google Ads Conversion Rate you see in your Google Ads account. In Google Ads, the Conversion Rate refers to the percent of clicks that end in a Google Ads conversion, defined by the Google Ads Conversion Tracking code. Please refer to the following article for more information on the differences between these two types of conversion tracking.
