Using etracker Optimiser without cookies

etracker Optimiser and cookies

By default, the etracker Optimiser only runs A/B tests and website overlays if etracker cookies are activated. The use of cookies has three advantages:

  1. Cookies can be used to display targeted content based on visit history or user profile properties.
  2. Recognition via cookies ensures that visitors always receive the same version of a test. On the one hand, this prevents possible irritations when visiting the website, and on the other hand, it enables clear statements about the success of the respective variants.
  3. In the case of longer customer journeys, target achievements during subsequent visits can also be attributed to the respective A/B testing variants. 

This means that A/B testing and smart messaging cannot be used in the standard, full function mode, if consent dialogues and cookie activation are not used.

However, the etracker Optimiser can optionally be operated in a cookie-less mode. This is intended for the following cases:

  • Consent dialogues are not used on the website and etracker Analytics is used exclusively in the standard cookie-less mode.
  • The cookie consent rate is not high enough to conduct meaningful tests. This can be particularly true if tests are carried out on specific sub-pages.

etracker Optimiser in cookie-less mode

In order to use the etracker Optimiser without cookies, the following parameter must be added to the parameter block of the tracking code:

var _etr = {eoForced:true}

The tracking code is as follows:

<! – Copyright (c) 2000-2021 etracker GmbH. All rights reserved. – >
<! – This material may not be reproduced, displayed, modified or distributed – >
<! – without the express prior written permission of the copyright holder. – >

<script type="text/javascript">
// var _etr = {eoForced:true};
// var et_pagename = "";
// var et_areas = "";
// var et_tval = 0;
// var et_tsale = 0;
// var et_tonr = "";
// var et_basket = "";
</script>
<script id="_etLoader" type="text/javascript" charset="UTF-8" data-block-cookies="true" data-respect-dnt="true" data-secure-code="XXXXX" src="//static.etracker.com/code/e.js"></script>
<! – etracker tracklet 5.0 end – >

(The data-secure-code “XXXXX” is to be replaced by the individual account key).

If etracker cookies have been activated after consent has been given, these will also be used for the delivery of etracker Optimiser projects.

Please note:

The parameter var _etr = {eoForced:true} enables the optimiser to also work in the case of users who do not allow cookies. To do this, the parameter must be passed in the etracker parameter block when the page is called up.

If the Optimiser is used in the cookie-less variant, not all functionalities are available. This includes, in particular, user recognition.

For A/B testing, this means that the assignment of the user to a page call (group A or group B) is not saved and is lost the next time the page is called up. This means that visitors can be presented with different variants when they call up pages with tests several times.

In addition, all conditions of the segmentation rules that are based on user recognition do not apply. With smart messages, this means that the smart message may be displayed to the user on every page.
