<h1>Web analytics</h1>

<p>Web analytics involves collecting, processing, visualizing web data to enable

critical thinking about how users interact with a web application.</p>

<h2>Why is web analytics important?</h2>

<p>User clients, especially web browsers, generate significant data while users

read and interact with webpages. The data provides insight into

how visitors use the site and why they stay or leave. The key concept to

analytics is <em>learning</em> about your users so you can improve your web

application to better suit their needs. </p>

<h2>Web analytics concepts</h2>

<p>It's easy to get overwhelmed at both the number of analytics services and

the numerous types of data points collected. Focus on just a handful of

metrics when you're just starting out. As your application scales and you

understand more about your users add additional analytics services

to gain further insight into their behavior with advanced visualizations such

as heatmaps and action funnels. The

post is an amusing read and provides context for how to begin and then grow

tracked metrics over time.</p>

<h3>User funnels</h3>

<p>If your application is

selling a product or service you can ultimately build a

<a href="http://moz.com/blog/building-your-marketing-funnel-with-google-analytics">user funnel</a> (often called "sales funnel" prior to a user becoming a customer)

to better understand why people buy or don't buy what you're selling. With

a funnel you can visualize drop-off points where visitors leave your

application before taking some action, such as purchasing your service.</p>

<h2>Open source web analytics projects</h2>

<p><a href="http://piwik.org/">Piwik</a> is a web analytics platform you can host yourself.

Piwik is a solid choice if you cannot use Google Analytics or want to

customize your own web analytics platform.</p>

<p><a href="http://www.openwebanalytics.com/">Open Web Analytics</a> is another

self-hosted platform that integrates through a JavaScript snippet that

tracks users' interactions with the webpage.</p>

<h2>Hosted web analytics services</h2>

<p><a href="http://www.google.com/analytics/">Google Analytics</a> is a widely used

free analytics tool for website traffic.</p>

<p><a href="https://mixpanel.com/">MixPanel</a>'s analytics platform focuses on mobile

and sales funnel metrics. A developer builds what data points need to be

collected into the server side or client side code. MixPanel captures that

data and provides metrics and visualizations based on the data.</p>

<p><a href="https://www.kissmetrics.com/">KISSmetrics</a>' analytics provides context

for who is visiting a website and what actions they are taking while on

the site.</p>

<p><a href="https://heapanalytics.com/">Heap</a> is a recently founded analytics service

with a free introductory tier to get started.</p>

<p><a href="http://www.crazyegg.com/">CrazyEgg</a> is tool for understanding a

user's focus while using a website based on heatmaps generated from mouse

movements. </p>

<h2>Web analytics learning checklist</h2>

<p><i class="fa fa-check-square-o"></i>

Add Google Analytics or Piwik to your application. Both are free and while

Piwik is not as powerful as Google Analytics you can self-host the application

which is the only option in many environments.</p>

<p><i class="fa fa-check-square-o"></i>

Think critically about the factors that will make your application successful.

These factors will vary based on whether it's an internal enterprise app,

an e-commerce site or an information-based application.</p>

<p><i class="fa fa-check-square-o"></i>

Add metrics generated from your web traffic based on the factors that drive

your application's success. You can add these metrics with either some custom

code or with a hosted web analytics service.</p>

<p><i class="fa fa-check-square-o"></i>

Continuously reevaluate whether the metrics you've chosen are still the

appropriate ones defining your application's success. Improve and refine the

metrics generated by the web analytics as necessary.</p>

<h2>Difference between monitoring and logging</h2>

<p>Monitoring and logging are very similar in their purpose of helping to

diagnose issues with an application and aid the debugging process. One way

to think about the difference is that logging happens based on explicit events

while monitoring is a passive background collection of data. </p>

<p>For example, when an error occurs, that event is explicitly logged through

code in an exception handler. Meanwhile, a monitoring agent instruments the

code and gathers data not only about the logged exception but also the

performance of the functions.</p>

<p>This distinction between logging and monitoring is vague and not necessarily

the only way to look at it. Pragmatically, both are useful for maintaining a

production web application.</p>
