I want to start this post with a big disclaimer over it I'm not publishing it in order to tell anyone how they should be doing the Google Analytics tracking to comply with the GDPR / CCPA . The goal of this post being able to start an open discussion about the reliability of this exposed method and any final decision should be taken the site owners under their own responsability. One of biggest…
It has been a hard week with all these vendors announcing the Four Hoursemen of the Cookies Apocalypse arrival.There're a lot of changes coming when we talk about cookies ( 1st, 3rd party ), ITP, GDPR, CCPA,etc . I understand it may be a terrible headache for anyone but we need to keep some calm. Last update has came from Google Chrome, which was expected to start…
It's been a long time since I wrote my post about how to prevent duplicate transactions on Google Analytics. At that point, the customTask wasn't a thing on the Google Analytics JS library, and the approach consisted of writing a cookie on each transaction and then work with some blocking triggers. It's a working solution for sure, but based on all the feedback I had over the years, it was not easy…
team has just added, in a stealth mode, a new Test API for the Custom Templates. This Test API will allow us to define some Unit Tests in order to be able to automate the testing of our template before publishing them. You will find a new tab within the templates editor named "test" where you will be able to run some code before the tests start, and then add a set of unit test…
Some years ago, I published my "Tealium Debugger" extension for Chrome which after a nice email my Inbox got, ended being named "UDO Debugger" ( no hard feelings at all ). You may click no the next CTA if you want to install the extension in your browser =) That version published circa Apr 2017, was just showing up the current app state on the page loads, the current account, profile, and environment details. There…
It happened to me a lot of times that while working with cookies that for whatever the reason I didn't remembered to add the domain name to the settings, or that I was not able to properly define the root domain. If you ever have had the need to set a cookie to the main root domain for your current domain, to make a cookie available for all the place, that depending on your current domain it may not be just enough to split the current hostname, because…
Since GDPR was announced and more even with the rise of Safari's ITP and the other upcoming protection feature by the other major browsers, the concers about users privacy was grown which is really nice. But despite browsers taking some actions to prevent the abuses, it's difficult to follow up the current cookies being used in our sites because we may end finding new ones that has been added by…
Yeah, I know, this has been done before by others, but since I had this piece of code around, I decided to publish it. It's not going to be usual, method since we'll be relying on sending a duplicate hit to our tracking subdomain. That way we'll be able to have our stuff tracked server-side in a secondary dimension while those hits will take care of setting the cookie expiring time on the main. isn't it cool? What we'll need A subdomain for our domain,…
