We collect different types of information about our users for two main reasons:
1. To help us to monitor and improve the services we offer.
2. To sell advertising space on the site, to help us keep the site free of charge.
1. For statistical purposes to track how many individual unique users we have and how often they visit our websites. We collect data listing which of our pages are most frequently visited and by which types of users and from which countries.
2. We use third parties to collect anonymous user information, sometimes through cookies and web beacons.
3. Our advertising is run by Guardian Select. To do this, Guardian News and Media and third party advertisers generate statistical cookies to track advertising impressions and conversions. There is further information about this below.
4. Placing cookies on your computer means we can serve you adverts that you might be more interested in, and allows us to control the number of times you see them and measure how effective the ad campaign has been. This helps us to keep the site free of charge. There is further information on this below, including how to opt out.
You can turn cookies off but if you do this you may not be able to use all services on the website and you might see more pop-ups and other intrusive advertising, as we won’t be able to limit what you see using cookies. You will, however, still be able to view editorial content.
For more information about cookies and managing them, including how to turn them off, please visit the Guardian’s page on Cookies.
About our advertising
In December 2011 the advertising service Ones to Watch uses, Guardian Select, introduced Online Behavioural Advertising (OBA) to our website. OBA allows Guardian Select to deliver targeted advertising to visitors to our website. OBA works by showing you adverts that are based on the type of content you have been reading, and delivering adverts which we believe may be of interest to you.
As you browse Ones to Watch, some of the cookies we place on your computer will be advertising cookies, so we can understand what sort of pages you are interested in.
This information we collect about behaviour on your computer enables us to group it with computers that show similar behaviour. We can then display advertising to your computer which is based on these interests.
It is important to remember that none of the OBA techniques we employ uses or requires us to collect information such as your name, email address, postal address or telephone number.
We may also share behavioural data with other websites. This may mean that when you are on other websites you are served advertising based on your behaviour on guardian.co.uk and guardiannews.com (and Ones to Watch), [on our sites] you may be served advertising based on your behaviour on other sites.
If you want to opt out of receiving online behavioural advertising this does not mean that you will no longer receive advertising when you are using guardian.co.uk or guardiannews.com. It just means that the advertising you see will not be customised for you.
If you would like more information about OBA and how to opt out of it, please visit youronlinechoices.com/uk/.
