README

A library for assigning an attribution channel to an entity based on tracking properties of that entity.

This library is in early release and is pending unit tests.

Use Case

A typical use case is that you have a trackable entity (a user or lead) which registers or is created via an API, with one or many tracking properties (http_referer, utm_source, utm_medium gclid, etc).

Given the entity and its tracking properties, you'd like to classify it into an attribution channel, and store that attribution channel (Organic Search -> Google) against the entity for reporting purposes.

Installation

composer require balfour/attribution-tracker

Usage

Step 1:

You create an AttributionTracker and define your tracking rules.

This repo includes a GenericChannel class for ease of use; although you can create a custom class implementing the ChannelInterface. In a real world app, your channels & rules might be models loaded from a database.

use Balfour\AttributionTracker\AttributionTracker;
use Balfour\AttributionTracker\GenericChannel;
use Balfour\AttributionTracker\Rules\GoogleAdsRule;
use Balfour\AttributionTracker\Rules\GoogleTrackingRule;
use Balfour\AttributionTracker\Rules\HttpRefererRule;

$tracker = new AttributionTracker();

$channel1 = new GenericChannel('Direct', 'Direct');
$tracker->setDefaultChannel($channel1);
// if the tracker can't find a matching rule, the default channel is returned

$channel2 = new GenericChannel('Paid Media', 'Google');
$rule1 = new GoogleAdsRule($channel2);
$tracker->addRule($rule1);

// this will match on utm_source = google AND utm_medium = ppc
$rule2 = new GoogleTrackingRule($channel2, 'google', 'ppc');
$tracker->addRule($rule2);

$channel3 = new GenericChannel('Referral', 'Facebook');
$rule3 = new HttpRefererRule($channel3, 'lm.facebook.com');
$rule4 = new HttpRefererRule($channel3, 'm.facebook.com');
$rule5 = new HttpRefererRule($channel3, 'l.facebook.com');
$rule6 = new HttpRefererRule($channel3, 'www.facebook.com');
$rule7 = new HttpRefererRule($channel3, 'facebook.com');
$tracker->addRules([$rule3, $rule4, $rule5, $rule6, $rule7]);

Step 2:

You have an object, implementing the TrackableEntityInterface, which you'd like to classify.

A GenericTrackableEntity is included in this repo; however in a real app, this may be a user or lead model.

use Balfour\AttributionTracker\GenericTrackableEntity;
use Balfour\AttributionTracker\TrackingMeta;

$props = new \stdClass();
$props->http_referer = 'https://google.co.za';
$props->utm_source = 'google';
$props->utm_medium = 'ppc';
$meta = new TrackingMeta($props);

$entity = new GenericTrackableEntity($meta);

Step 3:

With your AttributionTracker and TrackableEntityInterface, the entity can be classified.

$channel = $tracker->getChannel($entity);

var_dump($channel);
var_dump($channel->getCategory()); // Paid Media
var_dump($channel->getLabel()); // Google
var_dump($channel->getFullName()); // Paid Media -> Google
