Why Quantserve.com Script is injected after enabling the Ad Blocking Feature?

    Hello Igor,

    Hope you are doing well.

    I have noticed that after enabling the Ad Inserter plugin and especially the Ad Blocking Feature, I can see a big script getting injected at the footer if you look at the source page of my website.

    Below you can find the start of the script:

    / var ai_cookie_js=!0,ai_block_class_def="code-block"; /
    JavaScript Cookie v2.2.0
    https://github.com/js-cookie/js-cookie
    Copyright 2006, 2015 Klaus Hartl & Fagner Brack
    Released under the MIT license
    */

    Additionally, if we enable and use the external scripts option in the Ad Blocking Feature, then we can see the following external 5 sites + JS scripts are getting added as well which is slowing my site.

    data="https://securepubads.g.doubleclick.net/tag/js/gpt.js"
    data="https://www.google-analytics.com/analytics.js"
    data="https://contextual.media.net/dmedianet.js"
    data="https://z-na.amazon-adsystem.com/widgets/onejs"
    data="https://secure.quantserve.com/quant.js"

    We don’t like this approach of using an external script, especially quantserve.com.

    As soon as we disable Ad Blocking feature is disabled, all those external scripts and https://github.com/js-cookie/js-cookie are gone.

    This is slowing the website and we don’t want external scripts that create web beacons and cookies operated by audience research and behavioral advertising company Quantcast.

    Please advise?

    Your help is highly appreciated.

    Thank You!

    Hello,

    that’s why you have the option to disable external scripts if you don’t want them to be loaded. They are needed for reliable ad blocking detection as they will very likley be blocked. You can also disable each of them individually:

    Thank you @spacetime for your kind and fast response!

    I decided to stop using completely the Ad Blocking feature because even if I disabled the use of external scripts, the quantserve is still getting loaded on the site with this crazy big script coming from here: https://github.com/js-cookie/js-cookie

    You can see it here: https://www.screencast.com/t/QhW0AXncd

    I am happy without Ad Blocking, I would prefer better performance site speed and without quantserve Tracker/SPY.

    Thank You!

    When you disable ad blocking detection (or external scripts) no quantserve?script is loaded. And when it is loaded, it is loaded from an external file.

    The code on the screenshot is inline JavaScript code for client-side features. You can also load it from a file:

    Thanks for the note @spacetime,

    I have switched to JavaScript mode (File) and removed the use of external scripts as shown in the screenshot below:

    But quantserve.com is always getting loaded in the Footer as shown below:

    https://www.screencast.com/t/XRRFsncl8R4

    In between, I am using Server-side and NOT client-side as shown in the above screenshots.

    So, why quantserve.com is still getting loaded?

    Thanks!

    Ad blocking detection code is always loaded inline as othewise the file would be blocked and the detection would not work.

    The plugin does not load any quatcast script. The screenshot shows ad blocking detection code with debugging enabled.

    Thanks for the clarification @spacetime,

    I prefer to ditch the Ad Blocking module and keep it disabled. I don’t want extra code loaded.
    Ezoic Leap is detecting and scans if quantserve.com is available on the page and then flags it. Even if the plugin does not load any Quantcast script. You can see it below.

    I don’t want to see quantserve loaded on my pages.

    Disabling Ad Blocking feature solved this issue.

    Thanks!

    Interesting. But you can’t make conclusions only from one word you see somewhere. Not sure how such messages can help their users.

    BTW this word is present only in the debugging version of the code. In the production code (when debugging is not enabled) there is no such string.

    Thanks for note @spacetime,

    I don’t have debugging enabled in the Ad Inserter plugin. You can see below:

    Why this Word quantserve is showing then?

    And Ezoic said that: 37% of domains using this technology (quantserve) perform significantly worse than the average site.

    ??

    It seems some (not used) debugging code is present in the ad blocking detection script. Will be fixed with the next version.

    Thanks for reporting this!

    Ohhhhh… Good to hear that ??????

    I have been debugging this shit (quantserve) for two weeks to find the root cause.

    Looking forward for the fix in the next version.

    Many Thanks!

    Please try the latest development version:

    Hello @spacetime,

    Yes, the latest development version is working and quantserve is removed. Thank You!

    However, by using the File option for JavaScript Code, we have another script loaded in the footer: /ad-inserter/js/ai-functions.min.js?ver=2.7.25-0 which is nearly 43KiB. And Google PageSpeed Insights is complaining about Reducing unused JavaScript.

    And if we use Inline for JavaScript code in the footer, you have removed quantserve, Ezoic is happy, but you kept amazon, media.net, etc.

    To me, the best is to keep the Inline option instead of using File for JavaScript Code and disable Ad Blocking Feature. In this way, I don’t have anything loaded in the Footer anymore (ai-functions.min.js nor JavaScript Cookie v2.2.0 by https://github.com/js-cookie/js-cookie).

    I am using Google Ad blocking recovery option loaded which is enough for me, one script to load.

    Thanks!
