Web analytics is the measurement and analysis of data to inform an understanding of user behavior across web pages.
Analytics platforms measure activity and behavior on a website, for example: how many users visit, how long they stay, how many pages they visit, which pages they visit, and whether they arrive by following a link or not.
Businesses use web analytics platforms to measure and benchmark site performance and to look at key performance indicators that drive their business, such as purchase conversion rate.
Why Web Analytics Are Important
There’s an old business adage that whatever is worth doing is worth measuring.
Website analytics provide insights and data that can be used to create a better user experience for website visitors.
Understanding customer behavior is also key to optimizing a website for key conversion metrics.
For example, web analytics will show you the most popular pages on your website, and the most popular paths to purchase.
With website analytics, you can also accurately track the effectiveness of your online marketing campaigns to help inform future efforts.
How Web Analytics Work
Using this tag, the analytics tool counts each time the page gets a visitor or a click on a link. The tag can also gather other information like device, browser and geographic location.
Since some users delete cookies, and browsers have various restrictions around code snippets, no analytics platform can claim full accuracy of their data and different tools sometimes produce slightly different results.
