A cookie is a small piece of text that is sent to a browser and stored by it. Each cookie is associated with the domain that delivered it, and is given an expiry date and a name. Cookies are useful on the web because each time you visit a site within a domain, your browser checks to see whether it has a cookie for that domain and, if the cookie hasn’t expired, sends it back to the site. In this way, websites can keep you logged in and generally make the experience easier for you. Companies in the advertising industry, such as Infectious Media, also make use of cookies. We tell you how in this document.

Although we think of a web page as a single document, in fact it can consist of many different bits of content, all pulled together into a single page by a browser. For example each image on a page will be distinct and could come from anywhere on the web. So for each image a browser makes a request to the site where the image is located, before showing the content. Typically a beacon consists of an image that a browser is told to display so small that it does not interrupt the view of the page. This is sometimes known as a “tracking pixel”, a “clear gif”, a “web bug” or similar. When a browser wants to display that tiny image, it sends a request to us (for example) and in that request it will send any cookies that have not expired and that are set for our domain (see above for more info).

Cookies help us to recognise a browser we have already “met”. A web-beacon informs us when a computer/tablet or other device has seen a piece of content.

A typical scenario where this is useful is when you are on a site on which we have purchased advertising space. We show you an advert for (say) shoes that you find of interest, so you click on it. The ad is linked to a site called fabulousshoes.com which is managed by our advertiser. The advertiser puts our web-beacon on its site so that when you arrive there, we know that you have been safely redirected. If you subsequently make a purchase, another web-beacon might be put on the last page of the purchase process.

It is important to note that the Cookie does not identify you. It just identifies the browser that you are using. Unless you have chosen to give us your name (for example by registering with us), and are logged in to our site, the cookie does not tell us who you are.

Some companies pay thousands of web-sites to deploy their web-beacons so that they can build a large profiling database. We do not. We deploy web-beacons only as part of advertising campaigns for our clients. The web-beacons are placed on appropriate pages of our clients’ sites and help us analyse the performance of our clients’ advertising.

Currently we set and use some cookies ourselves but only on our site. These are called first party cookies.
When cookies are served by another domain they are called “third party cookies”. We use some third party cookies on our site.
We list these below:

For advertising on most external websites, we use a variety of proprietary and third party technologies to ensure the ads are efficiently and anonymously targeted to the audiences requested by our advertisers. We primarily use our own Impression Desk (IDB) technology but sometimes employ the use of other ad-exchange platforms, including but not limited to those operated by AppNexus and Google.

Depending on which technology platforms are used, a set of their cookies will be sent to your browser:

  • Whenever you visit a page that has advertising provided through that technology platform (whether or not it is us that eventually provides the advertising to you)
  • When you visit any page that has a web-beacon embedded from one or more of the technology platforms we work with


These cookies, and in particular the Impression Desk/AppNexus/DoubleClick user IDs which are contained in the cookies called idb, uuid2 and id respectively, are used for behavioural advertising; in other words: to help us recognise a browser so that we can provide more relevant advertising; and to recognise a user who has opted out of behavioural advertising.

Impression Desk and our third party technology partners are also integrated with a number of other advertising exchanges and third parties. For example in some cases where Impression Desk, AppNexus or DoubleClick sets a cookie, they may also send a number of other pixels to your browser at the same time that allows those third parties to synchronise any cookies that they have previously sent to your browser (and you have not deleted) with the Impression Desk, AppNexus or DoubleClick cookies. This is known as “cookie-syncing”.

For more detailed information on Impression Desk cookies please see below. For AppNexus and Google Doubleclick cookies please see the following links – AppNexus, Google Doubleclick.

Infectious Media has created a technology platform (Impression Desk) that is used to buy and deliver online advertising, including interest-based (behavioural) advertising, mostly through real-time bidding. Impression Desk is designed to use only non-personally identifiable information (non-PII). Impression Desk uses cookies to associate non-PII with browsers and devices, to facilitate targeted delivery of our clients online advertising campaigns . For a detailed privacy statement that applies to Impression Desk, and information about how we use technologies other than cookies, see our Privacy Policy. Below you will find information on Impression Desk cookies, all of which are set on the impdesk.com domain.

Cookie Names Purpose
idb This cookie contains a unique randomly-generated value that enables Impression Desk to distinguish browsers and devices. It is matched against information – such as advertising interest segments and histories of ads shown in the browser or device – provided by clients or other third parties and stored on Impression Desk. This information is used by clients to select advertisements for delivery by Impression Desk, and to measure the performance of, and attribute payment for, those advertisements. In addition, to enable clients to use non-PII they collect outside the Platform or acquire from other third parties, this cookie is sometimes matched to clients’ or other third parties’cookies that contain such non-PII. For more information about information collected and used on the Platform, see our Privacy Policy.
idb (opt out) When a user opts out of having Impression Desk used to select ads based on online behaviour, the unique value in uuid2 is deleted and replaced with the non-unique value “AA”. For more information about Impression Desk opt out, click here.

Not at the moment. But you can achieve the same result by changing your browser settings so that it does not store cookies. The site All About Cookies has good information about how to do this.

BUT, if you do stop cookies from being delivered then you may find your experience on our site to be quite limited. For example you may not be able to log in, or you may be asked to log in every time you click on a link.

Yes you can (please see our privacy policy to understand the effect of this). You can opt-out of behaviourally targeted advertising from us by clicking the “OBA Cookie Opt Out” button in this website’s footer, or by visiting Your Online Choices.

When you opt-out, we set the idb cookie to have an anonymous value. In this way the cookie still exists but it cannot be used to associate your visit with any of your previous visits. We also ask AppNexus to do the same with the uuid2 and DoubleClick with the id cookies.

Please note that the opt-out is browser specific. You must opt-out for every browser that you use. It is also reliant on the idb/uuid2/id cookies being alive. If you delete the cookies or they expire then on your next visit to a page with advertising provided by us or members of the AppNexus or DoubleClick services you will get a new idb/uuid2/id cookie and will need to opt-out again.

We are committed to following best practice in the areas of privacy and cookies. We will keep this policy and our use of cookies under constant review and we work with the IAB and other organisations in monitoring potential new standards.

In particular we will honour Do Not Track browser requests when we feel that a cross-industry standard is sufficiently set in stone for it to be meaningful.
We are also very interested in the possibilities offered by an alternative set of information (known as device identification or Device ID). Using Device ID may mean that we could avoid using cookies altogether, or at least reduce our usage. It will also provide, we hope, a greater degree of permanence to any opt-out from behavioural advertising. We are trialling Device ID technology now and will evaluate its privacy advantages and efficacy in early 2013.

As with our Privacy Policy, we may change this policy at any time. If the changes are material we will provide a suitably prominent notice so that you can read about the changes.
