Reasons for Google Analytics and Search Console Data Not Matching

While Search Console looks at the canonical URL of the landing page, Google Analytics reports the opened URL.
Google Analytics collects data through the Javascript code added to the pages on the websites, it cannot measure on the pages where this code is blocked or on the pages without a measurement code, but Search Console can. If the visitor to the website uses a plugin that blocks the Javascript code that triggers the GA code, or if this code is prevented from being triggered in any way, GA cannot collect data.
Search Console measures data on a single domain, if the Google Analytics property collects data from more than one domain (subdomains), there may be data differences.
Google Search Console transfers data according to the Pacific Time Zone, while Google Analytics transfers data according to the defined time zone. When the data is analyzed daily, if the two instruments do not measure in the same period, data differences arise.
While Search Console shows up to 1000 URLs, Google Analytics can show more than 1000 URLs, there is no URL limit.

Not every user from the SERP has visited the page. The user may have clicked on your page with the query he made on Google, but maybe he left the page as he clicked or closed the tab. In this case, the page may not have loaded and the GA code may not have been triggered, but GSC will count it.

Why Google Analytics and Search Console Data Never Match
