Displaying User Ads From Organic Sources

[XPgalaxy]

Hello; when I search for a keyword and enter my site organically, the URL appears as domain.com/page-name/?gclid=EAIaIQobChMIyMTE3LLf7gIViOhRCh0qewCTEAAYASAAEgIUwPD_BwE. When I check Google Analytics, it shows as coming from cost-per-click (CPC) advertising, even though the ad was not live at the time I visited. How do you think this is happening? This situation occurs only on one page; I checked other pages, and this issue does not occur.
