To capture if a visitor is from a Google Adwords click, you can use tracking parameters that are added to the destination URL of your ad. These parameters are automatically added by Google Adwords when you create a new ad, and they help you track the performance of your ad campaigns.
The tracking parameter that you can use to capture if a visitor is from a Google Adwords click is called "gclid". This parameter is added to the destination URL of your ad and contains a unique identifier for each click that comes from your ad.
To capture the "gclid" parameter, you can use a web analytics tool like Google Analytics. In Google Analytics, you can set up a conversion tracking goal that captures the "gclid" parameter when a visitor completes a desired action on your website, such as filling out a form or making a purchase. You can then view the performance of your ad campaigns in Google Analytics and see which ads are driving the most conversions.
To set up conversion tracking in Google Analytics, follow these steps:
Note: It's important to ensure that your website is correctly set up to capture the "gclid" parameter. You may need to work with your website developer or IT team to implement this tracking correctly.
Additionally, you can also use URL parameters in your landing pages to capture information about the referral source, including whether it is from a Google Adwords click. For example, you can add a parameter like "utm_source=google&utm_medium=cpc" to your landing page URL. This parameter will be passed along with the click and can be captured by your web analytics tool.
To capture this parameter, you can set up a custom tracking in your web analytics tool. In Google Analytics, you can create a custom report that filters for visitors who have the specific URL parameter you defined.
Keep in mind that tracking parameters added to the destination URL or using URL parameters require proper implementation and testing to ensure accurate tracking of Adwords traffic.
