Google Analytics is a web analytics service provided by Google, offering statistics and analytical tools for SEO and marketing purposes. As part of the Google Marketing Platform, Google Analytics helps organizations track website performance, gather visitor insights, and optimize marketing strategies. This service is freely available to users with a Google account.

How Google Analytics Works

Google Analytics utilizes page tags, specifically JavaScript tags, embedded in the code of each webpage. These tags collect data from website visitors and send it to Google’s data collection servers. The information is then used to generate reports, tracking various metrics like user traffic, bounce rates, session durations, and more. The service offers features such as data visualization tools, filtering, APIs, predictive analytics, segmentation, and integration with other Google products.
