<\/figure>\n<\/div>\nWith its latest ITP system update for iOS and macOS, Safari is blazing
\nthe trail for increased privacy among the major browsers. Earlier this year Firefox
\nalso updated its privacy policy, and even Microsoft and Google are set to give
\nusers more control over their cookie options. Are we witnessing the start of a
\nmajor new trend for web browsers?<\/p>\n
ITP has been around for a while now. Introduced in June 2017, Safari\u2019s With 14 and 15% respectively, the combined hits generated by Firefox and ITP doesn\u2019t only affect cross-site tracking \u00ad\u2013 This leads to distorted figures with an Firefox 66 has just introduced a pre-checked box in the new browser Safari\u2019s requirements state that cookies must be http-only, i.e. server-side, as opposed to client-side management (JavaScript). They must be explicitly set with a secure flag and only on https \u2013 secure http. Their collection domain also needs to be the same as the website domain, i.e. 1st party.<\/p>\n To ensure that their traffic is not significantly affected by ITP, analysts today need to be able to rely on a powerful and high-performance analytics solution. Analytics tools will always be impacted by web browser evolution, especially with the increasing shift towards data privacy. However, it is possible to be fully privacy-compliant and still maintain a clear and detailed overview of your traffic. CDDC (Custom Domain Data Collection) is an AT Internet solution that collects and sends data directly via your own domain name (instead of AT Internet\u2019s domain) so that tracking scripts are not disabled, making it possible to retrieve the majority of traffic lost due to ad blocker usage.<\/p>\n Another key to your analysis is identified In terms of 3rd<\/sup> party cookies, their If your users rely on ITP 2.2 and try to At the leading edge of the digital analytics You can find more in our video on Custom Domain Data Collection, and the impact of ad blockers and ITP on web analytics tools:<\/p>\n \n
\nprivacy feature began cancelling any 3rd<\/sup> party cookies from being
\ndeposited on a browser by default. In March this year, Firefox introduced new
\nprivacy rules with the
\nrelease of 66.0, and Safari came out with ITP 2.1 which also restricts 1st<\/sup>
\nparty cookies.<\/p>\n
\nSafari account for nearly a third of the internet. Blocking 3rd<\/sup>
\nparty cookies by default could therefore have a seismic impact on companies
\nthat rely on cross-site traffic measurement and retention analyses.<\/p>\nThe technical consequences <\/strong><\/h2>\n
\nby drastically limiting the lifetime of first party cookies, it potentially
\nprevents a user from being recognized from one session to the next.<\/p>\n
\ninflated number of unique visitors, audiences that do not reflect reality, and
\na complete fragmentation of conversion paths. In practical terms, on the basic
\nindicators, session and new visitor figures are artificially inflated. In terms
\nof allocation, ITP and especially ITP 2.2 have a bias in favour of free
\nchannels (less likely to include parameters in URLs) and contact points at the
\nend of the several-day process (favoured by the limited cookie duration). <\/p>\n

\ncookies; while it\u2019s private-browsing mode cancels all hits. Safari already
\nblocked 3rd<\/sup> party cookies by default \u2013 its new rule now means that all<\/em> remaining cookies that are not ITP

\nspreading their information to external sites \u2013 you can therefore carry out
\ncross-site analysis without affecting user privacy. This is the time to get
\nvisitors to subscribe to your sites.<\/p>\n
\ndays are numbered. For anonymised visitors, the domain structure will
\neventually need to be updated not just for analytics but for all resources. To
\nstay ahead of the game, you can avoid the impact of ongoing restrictions by
\nadjusting your measurements to ITP standards. Analytics solutions such as AT
\nInternet already offer its customers ways to analyse anonymised visitors with
\nITP activated on the browser.<\/p>\n
