About cookiesCookies are small files sent by web servers to your web browser (e.g. Internet Explorer, Firefox or Chrome), and stored on your computer’s hard drive.
The information is then sent back to the server each time the browser loads a website page from the server. This enables a web server to identify and track individual web browsers.
There are two main kinds of cookies: session cookies and persistent cookies. Session cookies are deleted from your computer when you close your browser, whereas persistent cookies remain stored on your computer until deleted, or until they reach their expiry date.
Great Ormond Street Hospital Children’s Charity uses certain essential cookies which are needed to enable the provision of our website’s core service, which is to raise funds for the charity through online donations and inform users of our fundraising activities. In accordance with the Privacy and Electronic Communications Regulations (EC Directive) 2011, no consent is needed to place these cookies on your browser.
In addition to these essential cookies, the cookies that follow are not essential to provide the core service but do help us to improve our website experience and measure our advertising activity. By using our website you are consenting to these cookies being placed on your browser, however you can disable them using your browser settings. Details of how to do this are listed below.
Google Analytics cookiesGreat Ormond Street Hospital Children’s Charity uses Google Analytics to analyse the use of this website. Google Analytics generates statistical and other information about website use by means of cookies, which are stored on your computer. Although these cookies are not essential to the core function of the website, they are useful in enabling the charity to raise more money through the website and to spend our donors’ money more effectively.
When you arrive on our website Google Analytics will place the following four cookies on your computer:
The _utma cookie helps us to identify whether you are new or returning visitor, or how long it has been since you visited our site. This helps us to identify what content is most useful for each type of visitor, and to assess whether our website is successful at providing useful content that means people want to come back. It is what is called a persistent cookie, which means it doesn’t expire and stays on your computer unless you choose to delete it.
_utmb & _utmc cookiesPurpose: Determining visitor session
The _utmb and _utmc cookies work together to calculate the time you spend on our site. The _utmb cookie takes a timestamp of the exact time you enter our site, and the utmc cookie takes a timestamp of the exact time you leave. Both the _utmb and _utmc cookies are “session” cookies, which mean they expire at the end of your session.
The information they provide helps us to understand whether pages are useful and engaging. For example, if 100 people visit a page and the average time on the page is just five seconds, we know that the page is not very useful and people do not find the page interesting. If the page has an average visit time of three minutes we can see that the content is working and can use that information to help us make underperforming pages work better to encourage more people to donate to the charity.
_utmz CookiePurpose: Tracking traffic sources and navigation
When you reach our site via a search engine result, a direct link, or an ad that links to your page, Google Analytics stores the type of referral information in the _utmz cookie. It provides us with the search term you typed into your search engine; which site you were on before you arrived; if the link was in an email, which email you received; if you clicked on an advert; or whether you typed our web address directly into your browser. The expiration date for the cookie is set as 6 months into the future. This cookie gets updated with each subsequent page you visit, and is therefore the cookie used to determine which pages you have visited on our site.
We use this information in a number of ways. For example, to understand if our advertising campaigns are working, to track if someone has made a donation, or if somebody who receives our email newsletter has visited our website. This helps us to spend our advertising budgets more effectively, or to change the content of our email newsletter to make it more relevant to our subscribers.
Double Click cookiesGreat Ormond Street Hospital Children’s Charity uses Double Click cookies to serve DART-enabled sponsored adverts on Google’s search results pages, and through Google’s search partner and content advertising network. The Double Click cookie is set and stored by your browser the first time you view our website or are served a DART-enabled ad. Your browser then sends that cookie ID back to the ad servers each time it requests a DART-trafficked ad. When a DART ad server receives one of these cookies, it queries the DART user database for information to help it serve an appropriately targeted ad.
We also use the Double Click to cookies to collect page views, sales and generated revenue linked to the adverts you have seen or clicked on. The Double Click cookie expires two years after it is set.
Our online advertising generates significant amounts of money for the charity. The information provided by Double Click cookies help us to better target our advertising, to assess the success of our advertising campaigns, and to make the most of our advertising budgets.
