tracking protection for sites and brands

Aloodo for Web Sites

How many of the people who visit your site are using some kind of protection from third-party tracking?

Ad fraud and attribution fraud can make data-driven marketing difficult, by creating confusing data about which campaigns and projects are bringing in your desired users.

Data on tracking-protected users can be a valuable way to check that your audience is authentic. When you know the tracking protection profile of your real users, campaigns that bring in bogus users will stand out right away—and help keep your marketing focused.

Measuring the problem

In order to measure tracking protection, you can use some first-party data collection to measure people's vulnerability to third-party data collection.

The three parts of that big question are:

This will be easy to do with a little single-pixel image and the Aloodo tracking detection script.

The lines that matter are:

<script src="/code/check3p.js"></script>
<script src=""></script>
<img id="check3p" src="/tk/sr.png"
 height="1" width="1" alt="">

I'm including a single-pixel image and two scripts: the Aloodo one and a new first-party script.

In most tracking protection configurations, the Aloodo script will be blocked, because appears on the commonly used tracking protection lists.

Step two: write the first-party script

The local script can be as simple as this: /code/check3p.js

All it does is swap out the tracking image source three times.

The work is done in the setupAloodo function, which runs after the page loads. First, it sets the src for the tracking pixel to js.png, then sets up two callbacks: one to run after the Aloodo script is loaded, and switch the image to ld.png, and one to run if the script can track the user, and switch the image to td.png.

Step three: understand your users

In this example you can use the regular server logs to compare the number of clients that load the original image, and the JavaScript-switched one, to the number that load the two tracking images.

(There are two different tracking callbacks because of the details of how Aloodo has to detect Privacy Badger, among other things. Not all tracking protection works the same.)

This can be connected to other analytics systems, too. Some analytics, however, are blocked by some tracking protection.

This data helps you create a report on the trackability of your site's real audience. If a campaign claims to reach the same people for less money, now you have the data to evaluate it.
