Piwik provides advanced ecommerce analytics features. This page will guide you through the following steps:

1. Enable Ecommerce on your website’s tracking.
2. Modify the Piwik tracking code to track Ecommerce data, products, orders on your website.
3. An overview of the Ecommerce analytics reports to help you understand and improve your online shop!

Enable Ecommerce Tracking

Ecommerce reporting is disabled by default. To enable Ecommerce analytics reporting, click onSettings > Websites > Edit” and select Ecommerce enabled from the dropdown in the Ecommerce column.

Once Ecommerce is enabled for a website, the Goals menu will be renamed to Ecommerce & Goals and will display Ecommerce reports.

If you do not see the Goals menu, it is probably because the Goals plugin is disabled.

Go toSettings & Pluginsto enable the Goals plugins.

Using a Piwik plugin for your Ecommerce Software

If you use a popular Ecommerce Software platform such as Magento, Prestashop, Zen Cart, oxid, VirtueMart or osCommerce, there could already be a Piwik Plugin that will install the tracking automatically on your pages. Click on this link and then download the Piwik plugin, install the plugin in your Ecommerce app, enter the Piwik URL, Website Id in the plugin settings. Your Ecommerce pages should then be automatically tagged with the Javascript code and track Cart Updates, Orders and Products/Category views.

    

If your platform is not in this list, please consider developing an open source plugin to enable Ecommerce Tracking for the software you use. We would be glad to add it the Plugin List and have the whole community benefit!

If you use a custom-made Ecommerce software, you must implement Ecommerce Tracking using the Javascript function calls, in your website pages.

Ecommerce tracking

Once you have enabled Ecommerce tracking for a website, you need to implement tracking of the various Ecommerce interactions on your website. There are three main Ecommerce interactions that are tracked with Piwik:

• Ecommerce Orders (and products),
• Ecommerce Cart update (and products),
• Product (and/or category) page views.

The following sections explain how to set up Ecommerce tracking, using the JavaScript TrackerEcommerce tracking methods.

Tracking Ecommerce Orders & Items Purchased (required)

Tracking Ecommerce orders and product details will allow Piwik to process reports on:

• Product SKU,
• Product name,
• Top Product categories and general overview of Ecommerce performance in your online shop.

To track Ecommerce orders, two Javascript functions are used:

1. addEcommerceItem(productSKU, productName, productCategory, price, quantity) This adds a product into the order, and must be called for each product in the order. productSKU is a required parameter, it is also recommended that you send other parameters if they are applicable in your Ecommerce shop.
2. trackEcommerceOrder(orderId, grandTotal, subTotal, tax, shipping, discount) This tracks an Ecommerce order and sends the data to your Piwik server, for both this order and products previously added. Only orderId and grandTotal (ie. revenue) are required.

Here’s an example of tracking an Ecommerce order containing two products – this code should be inserted in the “Order confirmation” page, once  the visitor has checked out and issued payment. If you installed Piwik correctly, your pages should already have a tracking code. The Ecommerce code below must be added and generated based on the Order:

[...]
// add the first product to the order
_paq.push(['addEcommerceItem',
"9780786706211", // (required) SKU: Product unique identifier
"Endurance: Shackleton's Incredible Voyage", // (optional) Product name
"Adventure Books", // (optional) Product category. You can also specify an array of up to 5 categories eg. ["Books", "New releases", "Biography"]
8.8, // (recommended) Product price
1 // (optional, default to 1) Product quantity
]);
// Here you can add other products in the order
[...]
// Specifiy the order details to Piwik server & sends the data to Piwik server
_paq.push(['trackEcommerceOrder',
"A10000123", // (required) Unique Order ID
35, // (required) Order Revenue grand total (includes tax, shipping, and subtracted discount)
30, // (optional) Order sub total (excludes shipping)
5.5, // (optional) Tax amount
4.5, // (optional) Shipping amount
false // (optional) Discount offered (set to false for unspecified parameter)
]);
// we recommend to leave the call to trackPageView() on the Order confirmation page
_paq.push(['trackPageView']);
[...]

Important notes about the functions parameters:

• price (parameter of addEcommerceItem() function), grandTotal, subTotal, tax, shipping, discount (parameters of trackEcommerceOrder() function) must be supplied as integer or floats, not as string. For example, all the following values are not valid: “14.4$”, “EUR14.4″, “14,4″, “14.4″. The following values are valid: 5, 3.3, 5.44. If your Ecommerce software provides the values as string only, you can call the Javascript function parseFloat() after making sure the string does not contain currency symbol or other characters, for example: parseFloat(“554.20″). Note that the Javascript parseFloat() does not support comma separated decimal values “25,3″ so you might have to replace the commas with dots before calling parseFloat().
• orderId parameter is a unique string identifier for the order. If the page containing the trackEcommerceOrder() call is refreshed by the customer a few hours or days after the initial Order, Piwik will automatically discard the order as it is already recorded. You can use the same orderId for different Websites id, but for a given website, orderId must be unique.
• If you print out some of these parameters in the HTML code, make sure that the Product SKUs, Names and categories are escaped in particular the ” character (double quotes), otherwise it may create Javascript parse errors.

Tracking Add to Cart & Items Added to the Cart (optional)

Every time a visitor adds (or updates, deletes) an item from his/her cart, you can use Piwik to track the latest cart subtotal as well as products left in the cart. Tracking cart updates will allow you to see how much revenue was left in your visitors’ carts for each day/week/etc, as well as getting reports on which products are most often left in the cart and which product categories are most often left abandoned in carts. Also, you can visualize each visit and the content of the cart they abandoned in the Visitor Log.

Some frequent causes for cart abandonment are:

• high shipping prices,
• complicated forms for new users (lack of “Anonymous checkout” option),
• complicated / lengthy checkout process,
• slow website,
• visitor was just browsing the site or wanted to compare total cost with competitor.

When you make changes to your website to lower the cart abandonment rate, and try to increase your revenues, you can use Piwik to understand if your changes are making a positive impact.

To track Shopping Carts with Piwik, you would call the javascript function trackEcommerceCartUpdate() every time a user is adding, updating or deleting a product from the cart.

Example tracking an Ecommerce order containing two products:

the code is added every time the “cart” page is loaded, or when the “Add to cart” button is clicked:

[...]
// add the first product to the order
_paq.push(['addEcommerceItem',
"9780786706211", // (required) SKU: Product unique identifier
"Endurance: Shackleton's Incredible Voyage", // (optional) Product name
["Adventure Books", "Best sellers"], // (optional) Product category, string or array of up to 5 categories
8.8, // (recommended) Product price
1 // (optional, default to 1) Product quantity
]);
// Here it is important to add all other products found in the cart, even the products not updated by the current "Add to cart" click
[...]
// Records the cart for this visit
_paq.push(['trackEcommerceCartUpdate',
15.5]); // (required) Cart amount
_paq.push(['trackPageView']);
[...]

Tracking Product Page Views & Category Page Views (optional)

Tracking product page views, and/or category page views lets Piwik process the conversion rate for each product and/or category.
It can be useful to know which product or category pages have converted your visitors into customers. For example, perhaps some product pages have below average conversion rates but generate high revenue. You may decide to improve these product pages and check their conversion rates over time.

To track a product or category page view, the function setEcommerceView( productSKU, productName, categoryName, price ) is used, just before the call to piwikTracker.trackPageView() on the product/category page.

Example Tracking a Product Page View

In this example, the following code is added to the Product page for the book “Endurance” which is in the category “Adventure Books”:

[...]
// all parameters are optional, but we recommend to set at minimum productSKU and productName
_paq.push(['setEcommerceView',
"9780786706211", // (required) SKU: Product unique identifier
"Endurance: Shackleton's Incredible Voyage", // (optional) Product name
"Adventure Books", // (optional) Product category, or array of up to 5 categories
20.11 // (optional) Product Price as displayed on the page
]);
_paq.push(['trackPageView']);
[...]

Example tracking a Category page view

This code is added on the Category page “Adventure Books”

[...]
// on a category page, productSKU and productName are not applicable and are set to false
_paq.push(['setEcommerceView',
productSku = false, // No product on Category page
productName = false, // No product on Category page
category = "Adventure Books" // Category Page, or array of up to 5 categories
]);
_paq.push(['trackPageView']);
[...]

Ecommerce reports in Piwik

In your Piwik interface, you can find Ecommerce reports by clicking on the main menu on “Ecommerce & Goals”.

Assuming you have set up Ecommerce tracking as explained above, Piwik will provide the following Ecommerce reports

• Ecommerce Metrics
  • Ecommerce orders
  • Total revenue
  • Average order value
  • Ecommerce conversion rate
  • Purchased products
  • Abandoned carts metrics: Visits with abandoned carts, revenue left in carts
• Ecommerce Reports
  • Ecommerce overview: revenue, orders, conversion rate, AOV (Average Order Value), etc.
  • Best productSKUs
  • Best product Names
  • Best product Categories
  • Ecommerce Log – displays all visits containing an Ecommerce Order, so you can visualize your customers clickpath
• Improved standard Reports
  • Existing reports will now include the “Ecommerce revenue” in the processing of the “Revenue” column.
  • These standard reports will also have a new metric column: “Ecommerce conversion rate”

Ecommerce Activity Overview

By default, Piwik will display the Ecommerce metrics for the selected date range, as well as a graph showing historical values for the selected metric.

Best Products & Best Categories

Piwik processes the list of Top Products sold, ordered by any of the Product metrics: Revenue, Quantity purchased, Unique Purchases, Average price, Average quantity, Visits or Conversion rate.

You can get the top products reports by Product SKU, by Product Name or by Category.

Note that you can access a help definition for each column by hovering on the column name.

Ecommerce Activity log

With Piwik, you can view (in real time!) the detailed Ecommerce log, showing all visits that have made a purchase on your website, as well as all visitors who have abandoned their shopping cart with products left in them.

Ecommerce Metrics in Standard Reports

Existing reports will now display the Ecommerce metrics in column list, so that Ecommerce performance can be visualized in any existing report and not only in the Ecommerce report page.

Advanced Ecommerce Statistics API

All the data available in the User Interface Ecommerce reports is also available via the Piwik Analytics API.

You can easily request the list of products purchased on your site, either grouped by Product SKU, Product Name or Product Category.

For each entry; the following metrics are returned:

• Total revenue
• Total quantity
• Average price
• Average quantity
• Number of orders (or abandoned carts) containing this product
• number of visits on the Product page
• Conversion rate

You can request these reports for Ecommerce orders, and also for abandoned carts.
