choreograph-create-pixel v1.4.1

Choreograph Create Pixel

This library lets you apply best practises to Create pixel development and implementation.

Features

• Supports scraper, segment and post-click pixels
• Supports dynamic page content updates
• Prevents scraping browser-translated content
• Continuous URL validation
• User interaction triggers
• Console debugger

Scraper pixels

Type: scraper

Scraper pixels are used to scrape (collect) data from websites, and store that data as products within an advertiser's product store.

Segment pixels

Types: viewed, basketed and purchased

Products in ads are shown by recommendation. Segment pixels determine this recommendation on a consumer level, by storing a cookie at different moments or events during the consumer's journey.

Post-click pixels

Types: attribution and conversion

Post-click conversion attribution tracks which clicked creative variant attributed to a website conversion. The attribution pixel collects the creative's impression ID from the URL (ccpid query parameter) on the landing page, and the conversion pixel logs this ID as a performance metric in Create when a user performed a conversion, like a purchase.

Quickstart

The following theoretical snippet includes all pixel types, can be embedded on every page of example.com, and will automatically determine which pixel to enable and disable through continuous URL validation.

ES module

import Pixel from "choreograph-create-pixel";

// Scraper pixel
new Pixel({
  advertiser: 0,
  type: "scraper",

  // Where on the website should this pixel be enabled?
  url: /example\.com\/products\/\d/,

  // Scrape functions are continuously re-evaluated for value changes
  scrape: {
    // Data layer example
    sku: () => window.dataLayer[0].product.sku,

    // DOM example
    name: () => document.querySelector("#product-name").innerText,

    // Helper example
    url: Pixel.getUrl,
  },
});

// Viewed segment pixel
new Pixel({
  advertiser: 0,
  type: "viewed",
  url: /example\.com\/products\/\d/,

  // Segment pixels only require an SKU to be scraped
  scrape: () => window.dataLayer[0].product.sku,
});

// Basketed segment pixel
new Pixel({
  advertiser: 0,
  type: "basketed",
  url: /example\.com/,

  // [Optional] Trigger by DOM events, rather than scrape content updates
  trigger: {
    event: "click",
    elements: "button.basket[data-sku]",
  },

  // The "element" parameter only becomes available when using a trigger
  scrape: (element) => element.getAttribute("data-sku"),
});

// Purchased segment pixel
new Pixel({
  advertiser: 0,
  type: "purchased",
  url: /example\.com\/cart/,

  trigger: {
    event: "click",
    elements: "button.checkout",
  },

  // Segment pixels support multiple SKUs
  scrape: () => window.dataLayer[0].cart.map((product) => product.sku),
});

// Attribution post-click pixel
new Pixel({
  advertiser: 0,
  type: "attribution",

  // Uniquely label each set of post-click pixels
  label: "example",

  // Match this URL to the landing page of your campaign
  url: /example\.com\/products\/\d/,
});

// Conversion post-click pixel
new Pixel({
  advertiser: 0,
  type: "conversion",
  label: "example",

  // Match this URL to the conversion page of your campaign
  url: /example\.com\/cart/,

  trigger: {
    event: "click",
    elements: "button.checkout",
  },
});

ES modules require manual bundling and transpiling before they can be safely embedded on websites.

CDN library

This alternative implementation method allows for direct embedding on pages without the need for bundling nor transpiling.

<script src="https://cdn.jsdelivr.net/npm/choreograph-create-pixel@1"></script>
<script>
  new ChoreographCreatePixel({
    // ...
  });

  new ChoreographCreatePixel({
    // ...
  });
</script>

Debugging

Enable browser console debugging by adding ?pixel_debug or #pixel_debug to the page's URL.

Configuration

Static methods (helpers)

.getUrl({ allowedQueryParameters, allowHash })

Returns the bare page URL without query parameters or location hash. This is highly recommended to exclude (UTM) tagging, or other unwanted side effects.

.getAllPathSegments()

Retrieves all path segments from the URL as an array. E.g. http://www.example.com/foo/bar returns ["foo", "bar"].

.getPathSegment(index)

Retrieves a specific segment from the URL. E.g. getPathSegment(0) on http://www.example.com/foo/bar returns "foo".

.getAllQueryParameters()

Retrieves all query string parameters from the URL as an object. E.g. http://www.example.com/?foo=bar returns { foo: "bar" }.

.getQueryParameter(key)

Retrieves a specific query parameter from the URL. E.g. getQueryParameter('foo') on http://www.example.com/?foo=bar returns "bar".
