Aloodo is the un-tracker
designed to be blocked
by all the popular Web privacy tools. You can use it
to help your users learn if they are still vulnerable
to third-party tracking, and start to do something
about it.
How it works
It starts with one script that attempts to load a
tracking
iframe.
<script src="https://ad.aloodo.com/track.js"></script>
Is the browser vulnerable to third-party tracking? Check it in a few lines of JavaScript.
if(typeof aloodo === 'object') {
aloodo.onLoad(trackerDetected);
aloodo.onDetected(trackingConfirmed);
}
The onLoad
callback is called when a fake tracker
iframe loads, and onDetected
is called when tracking
is confirmed. In the above example, Aloodo will call your
functions trackerDetected
and trackingConfirmed
.
What can sites do with it?
Brands: Understand how well your customers and prospects are protected from misleading tracking and targeting by fly-by-night competitors. And check your marketing technology against tracking protection rates by known customers to weed out
too good to be true
ad impressions.Ad-supported sites: Now it's easy to create a report for your advertisers on the trackability of your site's real audience—if a low-value competitor claims to reach the same people for less money, now you can show the difference between your real humans and their adfraud bots. (More: Aloodo for publishers)
Everybody: Warn users who might be trackable from site to site, so that you can recommend legit tracking protection in place of a problematic ad blocker.
The un-tracking pixel
The un-tracking pixel attempts to set a third-party
tracking
cookie. Use it on sites where you prefer
not to run third-party JavaScript.
It will prime the browser with a tracking
cookie, so that tracking will be detected more quickly
on a site that does have the script.
(If you have a main site where you want to show warnings or do other actions, you can put the pixel on your other sites. For example, some blogs will let you use a third-party image but not a third-party script.)
Include the un-tracking pixel with
<img src="https://ad.aloodo.com/px/www.example.com/"
alt="">
Substitute your site's hostname for www.example.com
.
If you set up the pixel URL correctly, Aloodo will serve the pixel with a long expiration time, so that the browser won't re-load it from every page on your site. (This helps minimize the amount of data that we can collect, and the load on our servers.)
You can use developer tools in your browser to check
that an Expires:
header is being set for the image.
If you do not see Expires:
and the browser is
re-loading the image on each page view, check that
the hostname in the image URL matches the hostname
part of the URL in the Referer header.
(Please contact us if you would like to start receiving reports based on aggregated usage of the un-tracking pixel on your site. We delete logs frequently, so we we are not set up to do reports from old data.)
