I would like to track clicks of a specific button on my website of people who came from the Facebook/Instagram ads I created.
I implemented the Facebook pixel which triggers on pageview.
I also put gtag('send', 'event','apply btn') on the Apply button. This shows me reports on Google Analytics but it doesn't show if those people came from the ads I created.
Is there a view on google analytics where you can see the name of the campaign the user came from, or is there something specific I might be missing in the configuration of the campaign or the gtag?
You have to add parameters to URLs to identify the campaigns that refer traffic.
utm_source: Identify the advertiser, site, publication, etc. that is sending traffic to your property, for example: google, newsletter4, billboard.
utm_medium: The advertising or marketing medium, for example: cpc, banner, email newsletter.
utm_campaign: The individual campaign name, slogan, promo code, etc. for a product.
There are also utm_content and utm_term.
