A cookie is a text-only string of data that is entered into the cookie file or “memory” of the web browser on your computer or mobile device. It will typically contain the name of the domain from which the cookie has come, the “lifetime” of the cookie, and a value, usually a randomly generated unique number. If you would like to know more about cookies we recommend you visit www.aboutcookies.org

Is this cookie section referring just to cookies?

No, it refers to all tracking devices that are used to store information such as Local Shared Objects, web beacons or transparent or clear gifs.


As the UK's leading technology media company, IDG UK is committed to providing our readers with the best user experience while visiting our sites. To help us improve and enhance this experience, we and third parties employ cookies to provide a wide range of crucial services to our users.

This section outlines the three main types of cookies operating across our sites:


These anonymous cookies are required for us to deliver core site functionality and are automatically enabled when you use our sites. All the required cookies operating on our sites are first-party cookies – meaning that they are set by our websites with the express purpose of helping the user experience. For example, these cookies currently help us to remember log-in details for returning users, lead to accurate survey results by preventing users from re-entering polls or mean that users are not required to repetitively complete forms when downloading whitepapers or interacting in Forums.

Site-analytics cookies

Site-analytical cookies are used by us to help improve site content and usability by tracking and recording user journey details such as what pages you viewed and for how long. For example, we currently use this information to identify what is the most popular content and how we should prioritise this content on our sites. These cookies are generated by the third-party web analytics providers we partner with and provide statistical data and insight only. Unless you have registered on our sites, these cookies are anonymous and they cannot identify you as an individual (see below).

Registration cookies

When you register on one of our sites, we automatically set cookies that enable us to deliver the services you have requested. These cookies identify the account you are signed up to and provide you with the relevant services or content associated with this account. If you have opted to be logged in automatically, then these cookies will remain on your device to help us to identify you when you return, otherwise these cookies will be automatically deleted when you close your browser. To enable us to improve the services we provide to registered users, we occasionally combine registration and site-analytical cookie data (see previous section) for statistical purposes. In addition, if registered users have indicated they are happy for us or third-party providers to contact them, we may also use this combined data approach to ensure they receive communications that are most relevant to them. You can change your registration preferences at any time by simply logging in and altering your account detail on any IDG UK websites.

Functional third party cookies

By partnering with third-party providers we can provide additional functionality that enhances the content and services we offer on our sites. For instance, we work with social media providers such as Facebook, LinkedIn and Twitter to help create a community environment for our users, where they can safely communicate and share relevant content and ideas with colleagues and friends.

We only work with respected partners that we feel will help provide the tools and services that our users want. In order to deliver these services via our website, these partners in some cases serve cookies on our sites. The companies that generate these cookies have their own privacy policies. Other than serving the coding they request to deliver these services, we don’t have access to how these companies employ these cookies. For more information on how to manage cookies being used by these parties, please click here.

Advertising-analytics cookies

At IDG UK we cap the number of adverts seen by each user. We do this by automatically serving a cookie on any first and third party advertisements appearing on our sites using the third party ad server provider. The same cookie is also used to help us, and the clients we work with, analyse the effectiveness of online campaigns to improve the marketing services provided. These cookies are entirely anonymous and used for statistical purposes only. For example, we frequently use these cookies to analyse how many users saw an advert and compare it against how many then clicked on the advert to find out more.

First party advertising cookies

To help users find out more about the products and services we offer, we often run in-house advertising campaigns on our own websites. To track the performance of these adverts, we use the advertising analytics cookies listed above to help us improve how we market our services to our users. None of these cookies involve collecting or using personally identifiable information like your name, email address, postal address or telephone number.

Third party advertising cookies

Many of the adverts you see on our sites are generated by third parties. Before running on our sites, adverts are vetted for their content and we only work with companies that we feel are appropriate for our users.

The companies that generate these adverts have their own privacy policies and may set their own or other third party cookies via these adverts. Other than setting up the coding they request when we receive the advert we don’t have control over how these companies employ cookies.

In some instances, you may find these adverts contain anonymous cookies which they use for analytical purposes such as to track how many people have seen an advert. Alternatively, they may use data from these cookies to anonymously target advertising to you on other websites based on your visit to our sites (known as Behavioural Retargeting).

To help our advertisers deliver more targeted and relevant advertising to our users, we also occasionally serve adverts using selected third party OBA service providers via platform providers such as Google, Krux and Pubmatic that target our users based on the content they may have viewed across our websites (known as Online Behavioural Advertising). These cookies are anonymous and do not involve using personally identifiable information like your name, email address or telephone number. 

If you wish to know more about how to manage your cookie preferences with these or other companies, please click here.

No third party advertising is in operation on the following IDG UK websites:

Please note that by permitting cookies to be used when visiting our sites you are agreeing to the use of cookies described in this section.


How to manage cookies

There are several approaches that can help you manage your cookie preferences. These options enable you delete all cookies that are being dropped on your machine or select only ones you are happy with. We have outlined these below as well as a number of useful sites that can provide you with more insight and guidance around cookie use and practice.

Option 1: Using your browser 

These days all browsers are set up with the capability to allow you to manage your cookie preferences directly. You can easily set your browser to stop accepting specific types of cookies, all cookies or even cookies from a particular website or provider. If you wish to not receive any cookies while visiting our sites for instance, we recommend that you use this approach. 

These settings are typically found in the 'options' or 'preferences' menu of your browser. However, each browser is set up slightly differently so, for the latest instructions on how to do this across the various different browsers, we recommend that you visit http://www.allaboutcookies.org/manage-cookies/

Option 2: Using trade associations/industry services

If you are principally concerned about third party cookies generated by advertisers, there are several websites that have been created to help you opt out of these. Below are a few we recommend: 

Your Online Choices: this site is an initiative from the EDAA that enables you to opt out from receiving cookies from hundreds of advertisers. To visit it, click here

Option 3: Contacting the company directly

A lot of major companies and advertisers enable you to opt out of the cookies they serve. To do this, we recommend you visit their specific cookies and privacy pages for more information. 

We have also provided a link below to the third party companies that we work with directly on a regular basis to deliver OBA advertising to you. Each of these provide opt out options which will ensure we can no longer serve advertising targeted on your online behaviour via these platforms:





Advertising analytical cookies:

When you visit any of our IDG UK sites or visit partner sites under our IDG TechNetwork, we drop a cookie via our analytics provider that enables us to analyse the performance of advertisements served to you. The data from this cookie also ensures we cap the number of adverts you see to enhance your site experience.

Please note that none of this information has any personal identifier information (PII) attached to it (such an email, telephone, name etc) and is for analytical purposes only.

The current provider we use for this service is Double Click for Publishers, a company owned by Google. If you wish to opt out of receiving a Double Click cookie, please click here 

Advertising cookies: 

In addition to the above, where we serve advertisements across third-party sites, we also use cookie data, where applicable, to help us deliver more targeted and relevant advertising to you. This targeting is based upon the content that you have viewed and is known as Online Behaviourial Advertising. We conduct this targeting via endorsed and carefully selected third-party partners that we work with.

The current partners that we work with to deliver these services are listed below. Each offer the capability to opt-out of these services and take privacy seriously which is one of the reasons we like them so much. To do this, simply click on the links provided.
