What are cookies anyway?
On this topic, Whatarecookies.com gives a very succinct answer:
“Cookies are small files which are stored on a user’s computer. They are designed to hold a modest amount of data specific to a particular client and website, and can be accessed either by the web server or the client computer. This allows the server to deliver a page tailored to a particular user, or the page itself can contain some script which is aware of the data in the cookie and so is able to carry information from one visit to the website (or related sites) to the next.”
What does EU cookie law mean for you?
Actually, we believe there is still uncertainty in its interpretation and implementation. However, if you are a Visual Website Optimizer customer based out of Europe, please read and understand what your country directive is (since EU law also differs from country to country). That said, the common consensus seems to be this: a website must inform its visitors that: a) cookies are being set on their computers/devices; b) explain what cookies are; c) communicate why cookies are being set and what sort of cookies are being set; d) give them an option or inform them how to opt-out of cookies/tracking.
To see how different websites are implementing this policy, we recommend you to read this excellent article by eConsultancy: 20 examples of EU cookie law compliance.
The difference between first party and third party cookies
Cookies are usually associated with one particular domain (the domain they are set on) and only that domain can access the data contained in the cookie. A first party cookie is where the domain you visit and the cookie owner are the same. For example, you visit www.some-web-app.com and the cookie information also says www.some-web-app.com.
A third party cookie is when you visit a certain domain, but the cookie dropped by that domain on your computer identifies itself as belonging to someone else. For example, you visit www.some-web-app.com but the cookie dropped has the information www.web-app-analytics.com
Visual Website Optimizer by default only uses first party cookies. However, if you have cross domain tracking enabled in the test, we use third party cookies to track conversions across multiple different domains. Please see details on Cross Domain Tracking feature to get more information. Note that only if your tests run across multiple domains simultaneously should you be bothered about third party cookies.
