Larger companies invested in data analytics and worked on modelling the missing data, while the rest of us either didn&#8217;t enable the banners at all or simply accepted that Google Analytics could no longer be trusted. Here&#8217;s our takeaway from Data Restart 2022 \u2014 the leading data analytics conference \u2014 and what you can do about the cookie apocalypse right now.<\/strong><\/p>\n\n\n\n<p>Over the past 12 months, a number of ways to tackle the data drop have emerged and improved. Google Analytics 4, Server-side Google Tag Manager, Consent Rate measurement, Enhanced Conversions and Consent Mode for Google Ads, Conversion API for Facebook, and more.<\/p>\n\n\n\n<p>Just when we e-shop managers started to breathe a little easier, data analysts began sounding the alarm again: <strong>for roughly the next three years, there will be a vacuum in which 3rd-party cookies (which we all rely on for ad targeting) disappear from browsers, while no systemic solution is ready to replace them \u2014 one that would let us keep serving relevant ads that customers appreciate and that generate revenue.<\/strong><\/p>\n\n\n\n<p><em>The ePrivacy Regulation, which is supposed to eliminate cookie banners and allow users to set preferences directly in their browser, won&#8217;t come into force until at least 2025.<\/em><\/p>\n\n\n\n<p>That&#8217;s why I headed to <a href=\"https:\/\/www.datarestart.cz\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Data Restart<\/strong><\/a> \u2014 organised by <strong><a href=\"https:\/\/academy.taste.cz\" target=\"_blank\" rel=\"noreferrer noopener\">Taste Academy<\/a><\/strong> \u2014 as I do every year, to hear how the best data analysts in the Czech Republic are preparing for the data apocalypse.<\/p>\n\n\n\n<p><strong>I&#8217;m not a data analyst myself, and I&#8217;m not a developer either.

We measured everything, everyone, everywhere. There was so much data that you could easily create a campaign offering a free coffee with cake to all secondary school students who walked within 100 metres of your shop between Monday and Friday. We knew about our customers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>which websites they visited<\/li>\n\n\n\n<li>what they did on those websites<\/li>\n\n\n\n<li>what they purchased<\/li>\n\n\n\n<li>what topics they liked reading about<\/li>\n\n\n\n<li>which devices they used to visit us<\/li>\n\n\n\n<li>what electronics they owned<\/li>\n\n\n\n<li>where they worked<\/li>\n\n\n\n<li>which shops and stores they visited<\/li>\n\n\n\n<li>what they did in their spare time<\/li>\n\n\n\n<li>&#8230;.<\/li>\n<\/ul>\n\n\n\n<p>Those days are over (and, frankly, that&#8217;s a good thing). <strong>Since 2022, users have the right to choose whether we can track them on our websites or not.<\/strong> This simple mechanism means that media houses, despite their best efforts, are losing roughly 20% of their data, while e-shops can easily lose 50%.<\/p>\n\n\n\n<p>Users express their preference via the so-called &#8220;cookie banner,&#8221; though soon it won&#8217;t just be about cookies \u2014 because their days are numbered too.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Technological_Changes_in_Browsers_%E2%80%94_The_End_of_Cookies\"><\/span><span class=\"ez-toc-section\" id=\"Technological_Changes_in_Browsers_The_End_of_Cookies\">Technological Changes in Browsers \u2014 The End of Cookies<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>It started with ad blockers, which simply strip ads from websites and block the storage of 3rd-party cookies in the browser. Users install ad blockers proactively, and data professionals have more or less learned to live with them.<\/p>\n\n\n\n<p class=\"has-pale-cyan-blue-background-color has-background\">\ud83d\udca1<strong> What are 3rd-party cookies?<\/strong> Third-party cookies are cookies stored in your browser by a website other than the one you&#8217;re currently visiting. For example, cookies from advertising platforms (like Google) that use the cookie to track your activity across the websites where they run ads.<\/p>\n\n\n\n<p>But browsers themselves have also started blocking 3rd-party cookies, which makes the problem much bigger. Firefox and Safari block 3rd-party cookies by default \u2014 this currently affects roughly 30% of web traffic, and that number will only grow, because it&#8217;s just a matter of time before other browsers, including Google Chrome, follow suit.<\/p>\n\n\n\n<p><strong>Due to the blocking of 3rd-party cookies, we&#8217;re losing data for remarketing, customer segmentation, and other marketing tools<\/strong> \u2014 without which, under the current setup of ad platforms, we should expect a significant drop in revenue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Google_Privacy_Sandbox\"><\/span><span class=\"ez-toc-section\" id=\"Google_Privacy_Sandbox\">Google Privacy Sandbox<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Google keeps delaying the rollout of cookie blocking in Chrome because it&#8217;s searching for a replacement solution. In simple terms: <strong>how to continue profiling users without needing 3rd-party data. One of the approaches being considered is Google Privacy Sandbox in Google Chrome.<\/strong> The browser itself will continue collecting data, but it won&#8217;t send all of it to ad platforms. Instead, it will only provide them with a user profile (e.g. that the user is interested in Apple iPhones).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Czech_Ad_ID\"><\/span><span class=\"ez-toc-section\" id=\"Czech_Ad_ID\">Czech Ad ID<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In the Czech Republic, an alternative approach to profiling users without cookies is emerging. Two major Czech digital players \u2014 Seznam and CPEx \u2014 have jointly created and launched the Czech Ad ID project, which enables ad targeting without the need for cookies. <strong>Instead, matching will be based on email addresses.<\/strong> <em>Sounds like 2000 all over again? And what about GDPR?<\/em><\/p>\n\n\n\n<p>Anyone can join Czech Ad ID; the only requirement is to use one-way email hashing. <strong>You hash the customer&#8217;s email on your end and send it to Czech Ad ID, which stores the hash in a database. Over time, this builds up a customer profile that can be targeted through programmatic advertising.<\/strong><\/p>\n\n\n\n<p>Just as with other forms of tracking, you&#8217;ll still need the user&#8217;s consent for processing their data for marketing purposes (Hello, cookie banner!).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Tackle_the_Data_Loss_Right_Now\"><\/span><span class=\"ez-toc-section\" id=\"How_to_Tackle_the_Data_Loss_Right_Now\">How to Tackle the Data Loss Right Now<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>As the volume and reliability of your data decline, your ad performance will drop too (at least according to the reports from ad platforms) \u2014 regardless of where or how much you&#8217;re spending.

Together, these make up your Consent Rate.<\/p>\n\n\n\n<p>You compare the number of page views with consent and divide it by the total number of page views. <strong>This tells you exactly how much data you&#8217;re actually losing in your analytics.<\/strong><\/p>\n\n\n\n<p class=\"has-pale-cyan-blue-background-color has-background\">\ud83d\udca1<strong>How to set up Consent Rate measurement?<\/strong> The team at <strong><a href=\"https:\/\/taste.cz\" target=\"_blank\" rel=\"noreferrer noopener\">Taste<\/a><\/strong> can help \u2014 they already have a ready-made tool for this.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Start_Using_Google_Analytics_4\"><\/span><span class=\"ez-toc-section\" id=\"Start_Using_Google_Analytics_4\">Start Using Google Analytics 4<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Yes! Deploy Google Analytics 4 (GA4) as soon as possible. You can run Universal Analytics (the current version of Google Analytics) and GA4 side by side, but start learning the new platform.<\/p>\n\n\n\n<p>As of July 2023, Universal Analytics is being sunset and you&#8217;ll have no choice but to use GA4. GA4 takes a fundamentally different approach to measurement, and at first glance it may seem like you can&#8217;t find the information you&#8217;re used to seeing in UA. That&#8217;s partly true. <strong>Some data you see in UA simply won&#8217;t be measurable in the future, and GA4 doesn&#8217;t even account for it.<\/strong><\/p>\n\n\n\n<p><strong>On the other hand, GA4 is designed to work with incomplete data.<\/strong> It uses algorithms to automatically model and estimate missing data. Once you&#8217;ve deployed a cookie banner, you&#8217;ll actually have higher-quality data in GA4 than you ever had in UA.<\/p>\n\n\n\n<p class=\"has-pale-cyan-blue-background-color has-background\">\ud83d\udca1 <strong>How to get started with Google Analytics 4?<\/strong> Ideally, attend a training course. One of the best options is the <strong><a href=\"https:\/\/academy.taste.cz\/google-analytics-4-masterclass\" target=\"_blank\" rel=\"noreferrer noopener\">GA4 Masterclass<\/a><\/strong> by Czech analytics expert Jan Tich\u00fd.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Deploy_Server-Side_Google_Tag_Manager\"><\/span><span class=\"ez-toc-section\" id=\"Deploy_Server_Side_Google_Tag_Manager\">Deploy Server-Side Google Tag Manager<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>This option is more suited to those running e-shops on custom platforms with server access. By using Server-Side GTM, you theoretically don&#8217;t lose data due to cookie restrictions, because everything is tracked on the server side and isn&#8217;t dependent on browser settings.<\/p>\n\n\n\n<p><strong>Server-side data collection helps with modelling, because you can compare it against data captured by client-side tracking codes in Google Analytics.<\/strong> But remember \u2014 even for server-side tracking, you still need user consent, regardless of whether you&#8217;re sending the data anywhere or not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Make_Logging_In_More_Attractive\"><\/span><span class=\"ez-toc-section\" id=\"Make_Logging_In_More_Attractive\">Make Logging In More Attractive<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The data you collect about customers in your own CRM system will become increasingly valuable, and you&#8217;ll need to feed it into advertising platforms (like Czech Ad ID or similar initiatives). Your job is to figure out how to encourage users to hand over their contact details (email or phone number). <strong>You want as many people as possible to log in on your website.<\/strong> Here are a few ideas:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a shopping basket that syncs across devices<\/li>\n\n\n\n<li>saved sizes on fashion e-shops<\/li>\n\n\n\n<li>members-only sections with exclusive content or offers<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CRM_in_a_Cookieless_World\"><\/span><span class=\"ez-toc-section\" id=\"CRM_in_a_Cookieless_World\">CRM in a Cookieless World<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Customer data has always been important, but measurement challenges (and the rising ad costs that come with them) are pushing marketers to embrace the &#8220;less glamorous&#8221; communication channels \u2014 especially working with their customer database. <strong>Honestly, when was the last time you called a customer to thank them for their order?<\/strong><\/p>\n\n\n\n<p class=\"has-pale-cyan-blue-background-color has-background\">\ud83d\udca1What is CRM (= Customer Relationship Management)? A CRM is any tool where you collect customer data. It could be a spreadsheet, your e-commerce platform, an email marketing tool\u2026<\/p>\n\n\n\n<p>Your CRM is a goldmine of information waiting to be tapped. If you connect the data correctly, you can find out \u2014 even without cookies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Which channels are bringing in new customers<\/li>\n\n\n\n<li>What made customers register with you<\/li>\n\n\n\n<li>Who your most loyal customers are<\/li>\n\n\n\n<li>Why customers leave, and what to offer them<\/li>\n<\/ul>\n\n\n\n<p>Within your CRM, you can segment customers (by purchased items, purchase frequency, order value, etc.) and create audiences from those segments that you can target with specific campaigns (display advertising, email marketing, phone outreach, etc.).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>I&#8217;d recommend starting with an audit of your email marketing, which I consider a <strong>low-hanging fruit<\/strong> for most e-shops \u2014 an opportunity to earn more money with minimal effort.<\/li>\n\n\n\n<li><strong>To evaluate an email campaign, you don&#8217;t need to rely on web analytics.<\/strong> Discount coupon usage can be reliably measured within your CRM database.<\/li>\n\n\n\n<li>Have a reactivation email campaign but people aren&#8217;t opening the emails? Take that segment, export the data to Facebook\/Google, and try delivering the same message via paid advertising.<\/li>\n\n\n\n<li>Look after your top customers. You can personally call them on their birthday and ask what would make them happy.<\/li>\n\n\n\n<li>You can call customers who haven&#8217;t bought from you in over a year \u2014 not to sell, just to ask why they stopped shopping with you.<\/li>\n\n\n\n<li>Set up email automation (or make phone calls) targeting customers who placed a high-value order but haven&#8217;t collected it from the pickup point, risking a return.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/www.loudavymkrokem.cz\/wp-content\/uploads\/2023\/05\/appeltauer-mailing.png\" alt=\"CRM and mailing strategy overview\" class=\"wp-image-58315\" title=\"\"><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"List_and_Measure_All_Customer_Subscriber_Sources\"><\/span><span class=\"ez-toc-section\" id=\"List_and_Measure_All_Customer_Subscriber_Sources\">List and Measure All Customer \/ Subscriber Sources<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>You&#8217;ll probably be surprised by the sheer number of ways customers and contacts end up in your database. Write down all the sources, review them, and optimise where possible (add incentives, etc.). Here are the typical ways customers enter the system:<\/p>\n\n\n\n<p><strong>During a website visit<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>newsletter sign-up in the footer<\/li>\n\n\n\n<li>newsletter sign-up via pop-up<\/li>\n\n\n\n<li>newsletter sign-up from a promotional offer<\/li>\n<\/ul>\n\n\n\n<p><strong>During checkout<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>guest checkout with newsletter opt-in<\/li>\n\n\n\n<li>account registration during purchase<\/li>\n<\/ul>\n\n\n\n<p><strong>From campaigns<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>newsletter sign-up from a Facebook campaign<\/li>\n<\/ul>\n\n\n\n<p><strong>Offline<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>in-store registration<\/li>\n\n\n\n<li>sign-up via offline competition at a trade fair<\/li>\n<\/ul>\n\n\n\n<p>There are many more registration methods, and you&#8217;ll work with each source differently. Next, find out how you&#8217;re currently handling each group and whether anything can be improved. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Are you tagging the source of each contact in your database?<\/li>\n\n\n\n<li>What newsletters are they receiving?<\/li>\n\n\n\n<li>What onboarding campaigns are running for them?<\/li>\n\n\n\n<li>Do they have their own sales funnel?<\/li>\n\n\n\n<li>What do you want to do with them going forward?<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Consolidate_All_Your_Data_in_One_Place\"><\/span><span class=\"ez-toc-section\" id=\"Consolidate_All_Your_Data_in_One_Place\"><strong>Consolidate All Your Data in One Place<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Choose a system where you&#8217;ll centralise your data. I use <a href=\"https:\/\/loudavymkrokem.cz\/en\/ecomail-review-email-marketing\/\">Ecomail<\/a> for this, for example. What do you know about your customers that you can leverage in campaigns? Things like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>gender<\/li>\n\n\n\n<li>name<\/li>\n\n\n\n<li>email<\/li>\n\n\n\n<li>phone number<\/li>\n\n\n\n<li>name day, birthday<\/li>\n\n\n\n<li>registration date<\/li>\n\n\n\n<li>registration source<\/li>\n\n\n\n<li>reason for registration<\/li>\n\n\n\n<li>product categories purchased<\/li>\n\n\n\n<li>specific products purchased<\/li>\n\n\n\n<li>purchase frequency<\/li>\n\n\n\n<li>order value<\/li>\n\n\n\n<li>email engagement, etc.<\/li>\n<\/ul>\n\n\n\n<p><strong>And then experiment. \u263a\ufe0f<\/strong> The possibilities for leveraging your database are practically endless. You&#8217;ll find plenty of tips in our <a href=\"https:\/\/loudavymkrokem.cz\/en\/ecomail-review-email-marketing\/\"><strong>Ecomail review<\/strong><\/a> and in our article with <a href=\"https:\/\/loudavymkrokem.cz\/en\/email-marketing-tips\/\"><strong>18 practical email campaign tips<\/strong><\/a>.<\/p>\n\n\n\n<p>There was much more covered at the conference.
