Web Analytics

Definition

Web analytics is the practice of collecting, measuring, and analyzing data about visitor behavior on a website to understand traffic, engagement, and conversion performance.

Overview

Web analytics turns raw visitor activity — page views, clicks, session duration, traffic sources, device types, and conversion events — into data that businesses use to understand how people find and use their site. Most implementations work by embedding a small tracking snippet or SDK on each page, which fires events to an analytics platform as users interact with the site; tools like Google Analytics and Google Tag Manager are among the most widely used for this. Data is typically aggregated into dashboards covering acquisition (where visitors come from), behavior (what pages and features they use), and conversion (whether they complete a goal like a purchase or signup). Key metrics include sessions, users, bounce rate, average engagement time, conversion rate, and funnel drop-off between steps of a process like checkout or onboarding. Beyond simple pageview counting, modern web analytics platforms support event-based tracking of specific interactions (button clicks, video plays, scroll depth), audience segmentation, A/B test measurement, and attribution modeling that credits marketing channels for conversions. Web analytics data increasingly informs SEO strategy, product decisions, and marketing spend, and it intersects with privacy regulation — cookie-based tracking is subject to consent requirements under laws like GDPR, pushing many platforms toward more privacy-conscious, sometimes cookieless measurement approaches. Complementary tools like Google Search Console focus specifically on organic search visibility rather than on-site behavior.
