Acoustic Digital Analytics Impression Attribution is an optional module that allows you to track impressions from offsite marketing placements directing traffic back to a Digital Analytics-tagged web site.
Through sophisticated cookie mapping and attribution logic, it is possible to understand basic information such as impressions, clicks, and click-throughs, in addition to advanced metrics such as "attributed" sales, orders, sessions, and events over defined attribution windows and selected credit logic. This module may require a tag library update. To determine if you need an update, please contact your assigned Implementation Engineer or Customer Support.
Using Impression Attribution, it is possible to answer questions such as:
- Am I under-invested in Display Advertising with a particular publisher or network?
- Do those who convert on my site ever view our ads? Where do they see them?
- Does someone who views our High Interest Checking ad banner on a particular site sign up for a new account on our site within 90 days?
- How often is a particular ad viewed across all sites? By how many unique viewers?
- Do those who watch our syndicated video or view our micro-sites ultimately convert on our site?
- What components of our widget are people viewing/utilizing? Does interest in a particular widget component signal a high likelihood of a downstream Home Goods purchase?
Independent Request
In order to limit the impact on performance/latency on the publishing site, independent requests are preferred. In the case of a micro-site, the request may simply be included directly into the page source. In the case of a display ad, the request would be called simultaneous with the ad request. In other words, the publishing site code would make a request for both the Digital Analytics Impression Attribution tag and the actual advertisement content at the same time.
Sample Independent Request:
http://data.cmcore.com/imp?tid=17&ci=11111111&vn1=4.1.1&vn2=imp&ec=UTF-
8&rnd=1234567890123&cm_mmc=Washington%20Post-_-Display%20Ads-_-Boat%20

Redirect request
The 'redirect' request leverages a redirect through which the publishing site requests the Digital Analytics Impression AttributionMarketing Impression Attribution tag and it, in turn, redirects to the advertisement URL. The redirect URL (?ul=) must come before the tag parameters.
Sample Redirect Request:
http://data.cmcore.com/imprd?ul=http://ad.doubleclick.com/ad/N733/B32049394.2%3

Marketing impression tag specification
The Marketing Impression tag is a lightweight direct image request to Digital Analytics that sets or collects a 3rd party cookie (CoreID6).
Digital Analytics records an "impression" for each tag received. Data.cmcore.com responds to requests with a transparent 1x1 pixel GIF image.
Parameter | Required | Description |
---|---|---|
Protocol | Required | http:// or https:// |
Request Domain | Required | The Digital Analytics domain receiving this request - always use "data.cmcore.com" |
Requested File | Required | "/imp?" is used for an independent request. "/imprd?" is used for a redirect request. |
Tag ID (tid=) | Required | "17" indicates a 'Marketing Impression' - always use this value. |
Client ID (&ci=) | Required | The 8-digit 9-series ID value, or 5-series ID + siteID value (5xxx0000%7CsiteID) |
&vn1=4.1.1 &vn2=imp &ec=UTF-8 | Required | Always include these parameter values as demonstrated. |
Marketing Program (cm_mmc=) | Required | Four-level definition of the Marketing Program using the standard "vendor-_-category-_-program-_-item" convention (see 4.1). This should match the associated marketing URL values. |
Random Number (rnd=) | Required | Any random number (integer up to 13-bytes) sent per tag to break the client request cache. Identical http requests sent from the same client in a session can be redirected to the local cache if that client supports caching. This parameter can be used in addition to the required st= or when a new st= timestamp parameter value cannot be regenerated per tag sent. |
Marketing Attributes | Optional | Up to 15 "-_-" delimited 100-byte attribute values. This should match the associated marketing URL values. |
Marketing program and impression correlation
The Marketing Program link URL and associated Marketing Impression requests for the same Advertisement should contain the same Marketing Program (cm_mmc=) and Marketing Attribute (cm_mmca1-a15) parameter values.
For the following display Ad example linking to your site's home page:
http://data.cmcore.com/imp?tid=17&ci=11111111&vn1=4.1.1&vn2=imp&ec=UTF-8&cm_mmc=
Washington%20Post-_-Display%20Ads-_-Boat%20Insurance-_-Boat_vA_c432&cm_mmca1=
300x250&cm_mmca2=german
The target URL should contain:
http://www.yoursite.com?cm_mmc=Washington%20Post-_-Display%20Ads-_-Boat%20
Insurance-_-Boat_vA_c432&cm_mmca1=300x250&cm_mmca2=german
Matching Marketing Program parameters and Marketing Attributes across the Marketing Impression and Marketing URL ensures correct marketing reporting.
Independent request HTML example
In order to limit the impact on performance/latency on the publishing site, independent requests are preferred. In the case of a micro-site, the request may simply be included directly into the page source. In the case of a display ad, the request would be called simultaneous with the ad request. In other words, the publishing site code would make a request for both the Digital Analytics Impression Attribution tag and the actual advertisement content at the same time.
Sample HTML for Independent Request:
<a alt="banner ad link" href="http://www.thesite.com/landingpage.html?
cm_mmc=Washington%20Post-_-Display%20Ads-_-Boat%20Insurance-_-Boat_vA_c432&
cm_mmca1=300x250&cm_mmca2=german"><img alt="a banner ad image" height="45"

Testing marketing impression tags
The Marketing Impression Attribution reporting module is not available in Digital Analytics test reports.
About this task
To test new impression requests, use the following procedure.
Procedure
- Create a local HTML page for your new Impression tag following the HTML example in the Independent request HTML example and modify it as needed if you are testing a Redirect request.
- Modify the HTML anchor href= to point to a tagged production web site page sending data to the same Client ID (&ci=) value as the new Impression request.
- Run the local HTML in your browser to send the impression tag and display the link.
- Click the link to navigate to the tagged production landing page and use tagbar to verify a Page View or Technical Properties tag is sent with the expected cm_mmc= value in the Destination URL (ul) parameter.
- The next day, generate an Explore / Marketing module report for the prior day, including relevant Impression Attribution metrics. To reduce the number of rows in this production report, consider Filtering the report by the Marketing Program (cm_mmc=) VCPI value associated with the test.
