The defaultJavaScript tracking snippet for Google Analytics runs when a web page is first loaded and sends a pageview hit to Google Analytics. If you want to know about more than just pageviews (e.g. where the user clicked, how far they scroll, did they see certain elements, etc.), you have to write code to capture that information yourself.

Since most website owners care about a lot of the same types of user interactions, web developers end up writing the same code over and over again for every new site they build.

Autotrack was created to solve this problem. It provides default tracking for the interactions most people care about, and it provides several convenience features (e.g. declarative event tracking) to make it easier than ever to understand how people are interacting with your site.

Theautotrack.js file in this repository is small (8K gzipped) and comes with all plugins included. You can use it as is, or you can create acustom build that only includes the plugins you want to make it even smaller.

The following table briefly explains what each plugin does; you can click on the plugin name to see the full documentation and usage instructions:

Disclaimer: autotrack is maintained by members of the Google Analytics developer platform team and is primarily intended for a developer audience. It is not an official Google Analytics product and does not qualify for Google Analytics 360 support. Developers who choose to use this library are responsible for ensuring that their implementation meets the requirements of theGoogle Analytics Terms of Service and the legal obligations of their respective country.

To add autotrack to your site, you have to do two things:

1. Load theautotrack.js script file included in this repo (or acustom build) on your page.
2. Update yourtracking snippet torequire the various autotrack plugins you want to use on thetracker.

If your site is currently using thedefault JavaScript tracking snippet, you can modify it to something like this:

<script>window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+newDate;ga('create','UA-XXXXX-Y','auto');// Replace the following lines with the plugins you want to use.ga('require','eventTracker');ga('require','outboundLinkTracker');ga('require','urlChangeTracker');// ...ga('send','pageview');</script><scriptasyncsrc="https://www.google-analytics.com/analytics.js"></script><scriptasyncsrc="path/to/autotrack.js"></script>

Of course, you'll have to make the following modifications to the above code to customize autotrack to your needs:

• ReplaceUA-XXXXX-Y with yourtracking ID
• Replace the sample list of pluginrequire statements with the plugins you want to use.
• Replacepath/to/autotrack.js with the actual location of theautotrack.js file hosted on your server.

Note: theanalytics.js plugin system is designed to support asynchronously loaded scripts, so it doesn't matter ifautotrack.js is loaded before or afteranalytics.js. It also doesn't matter if theautotrack.js library is loaded individually or bundled with the rest of your JavaScript code.

If you use npm and a module loader that understandsES2015 imports (e.g.Webpack,Rollup, orSystemJS), you can include autotrack in your build by importing it as you would any other npm module:

npm install autotrack

// In your JavaScript codeimport'autotrack';

Note: autotrack's source is published as ES2015, and you will need to make sure you're not excluding it from compilation. See#137 for more details.

The aboveimport statement will include all autotrack plugins in your generated source file. If you only want to include a specific set of plugins, you can import them individually:

// In your JavaScript codeimport'autotrack/lib/plugins/event-tracker';import'autotrack/lib/plugins/outbound-link-tracker';import'autotrack/lib/plugins/url-change-tracker';

The above examples show how to include the autotrack plugin source in your site's main JavaScript bundle, which accomplishes the first step of thetwo-step installation process. However, you still have to update your tracking snippet and require the plugins you want to use on the tracker.

// Import just the plugins you want to use.import'autotrack/lib/plugins/event-tracker';import'autotrack/lib/plugins/outbound-link-tracker';import'autotrack/lib/plugins/url-change-tracker';ga('create','UA-XXXXX-Y','auto');// Only require the plugins you've imported above.ga('require','eventTracker');ga('require','outboundLinkTracker');ga('require','urlChangeTracker');ga('send','pageview');

Note that it's generally not a good idea to include any analytics as part of your site's main JavaScript bundle since analytics are not usually critical application functionality.

If you're using a bundler that supports code splitting (via something likeSystem.import()), it's best to load autotrack plugins lazily and delay their initialization until after your site's critical functionality has loaded:

window.addEventListener('load',()=>{constautotrackPlugins=['autotrack/lib/plugins/event-tracker','autotrack/lib/plugins/outbound-link-tracker','autotrack/lib/plugins/url-change-tracker',// List additional plugins as needed.];Promise.all(autotrackPlugins.map((x)=>System.import(x))).then(()=>{ga('create','UA-XXXXX-Y','auto');ga('require','eventTracker',{...});ga('require','outboundLinkTracker',{...});ga('require','urlChangeTracker',{...});// Require additional plugins imported above.ga('send','pageview');});})

If you're not sure how do use code splitting with your build setup, see thecustom builds section to learn how to manually generate a custom version of autotrack with just the plugins you need.

All autotrack plugins accept a configuration object as the third parameter to therequire command.

Some of the plugins (e.g.outboundLinkTracker,socialWidgetTracker,urlChangeTracker) have a default behavior that works for most people without specifying any configuration options. Other plugins (e.g.cleanUrlTracker,impressionTracker,mediaQueryTracker) require certain configuration options to be set in order to work.

See the individual plugin documentation to reference what options each plugin accepts (and what the default value is, if any).

Autotrack comes with its own build system, so you can create autotrack bundles containing just the plugins you need. Once you'veinstalled autotrack via npm, you can create custom builds by running theautotrack command.

For example, the following command generates anautotrack.js bundle and source map for just theeventTracker,outboundLinkTracker, andurlChangeTracker plugins:

autotrack -o path/to/autotrack.custom.js -p eventTracker,outboundLinkTracker,urlChangeTracker

Once this file is generated, you can include it in your HTML templates where you loadanalytics.js. Note the use of theasync attribute on both script tags. This preventsanalytics.js andautotrack.custom.js from interfering with the loading of the rest of your site.

<scriptasyncsrc="https://www.google-analytics.com/analytics.js"></script><scriptasyncsrc="path/to/autotrack.custom.js"></script>

All autotrack plugins supportmultiple trackers and work by specifying the tracker name in therequire command. The following example creates two trackers and requires various autotrack plugins on each.

// Creates two trackers, one named `tracker1` and one named `tracker2`.ga('create','UA-XXXXX-Y','auto','tracker1');ga('create','UA-XXXXX-Z','auto','tracker2');// Requires plugins on tracker1.ga('tracker1.require','eventTracker');ga('tracker1.require','socialWidgetTracker');// Requires plugins on tracker2.ga('tracker2.require','eventTracker');ga('tracker2.require','outboundLinkTracker');ga('tracker2.require','pageVisibilityTracker');// Sends the initial pageview for each tracker.ga('tracker1.send','pageview');ga('tracker2.send','pageview');

Autotrack will safely run in any browser without errors, as feature detection is always used with any potentially unsupported code. However, autotrack will only track features supported in the browser running it. For example, a user running Internet Explorer 8 will not be able to track media query usage, as media queries themselves aren't supported in Internet Explorer 8.

All autotrack plugins are tested in the following browsers:
