- Web analytics cookies / Marketing effectiveness cookies
- These cookies allow us to understand general customer behaviour on thetrainline.com; such as which bits of our website customers use, where they exit the site and, if anything goes wrong, where it happens; helping us to make our website better. We also track how customers find our website, for example which search engine was used or which online adverts were clicked on before visiting us, helping us understand our marketing effectiveness. Data is anonymised and aggregated so we can monitor trends and count visitors rather than tracking individual customers. They have no impact on what you see on the website and do not store or track any of your personal data.
- Cookies for personalising your experience on our website
- These cookies allow us to understand the way you specifically use our website and tailor your experience on thetrainline.com. For example, by understanding the searches and selections you make on our website, we may be able to show you special offers and deals that are more relevant to you. If you have searched for tickets on a particular route, we may show you offers for this route in future.
- Cookies for personalising your experience elsewhere on the internet
- These cookies allow us to understand your online behaviour and tailor your experience outside of our site. For example, the adverts you see for thetrainline.com on other websites may be specially targeted to include the routes that you have searched for on thetrainline.com.
- Cookies for optimising the content shown on our website
- We sometimes may wish to test a change or new feature on the site to see if it is effective before rolling it out to all our users. Cookies allow a random sample of site visitors to see it one way, and a different group another and ensure that you consistently get the same experience on repeat visits.
